Claim Rejections - 35 USC § 103
In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status.
The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action:
A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made.
The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows:
1. Determining the scope and contents of the prior art.
2. Ascertaining the differences between the prior art and the claims at issue.
3. Resolving the level of ordinary skill in the pertinent art.
4. Considering objective evidence present in the application indicating obviousness or nonobviousness.
Claims 1-3, 5, 7-9, 11, and 15-19 are rejected under 35 U.S.C. 103 as being unpatentable over Mahasenan et al. (US 2014/0198670), hereinafter “Mahasenan”, in view of Kasch et al. (US 2018/0060476), hereinafter “Kasch”.
Regarding claim 1, Mahasenan teaches:
A method for assisting private wireless network access point (AP) placement, comprising:
positioning two or more devices with radio frequency (RF) transmitter and receiver functionality (T/R devices) at a plurality of locations within a site (see Mahasenan, Figs. 1 and 2, par. [0030]: At block 232, method 230 includes placing a number of wireless nodes at a first set of locations. The number of wireless nodes can include nodes that are capable of sending and/or receiving wireless messages, and see par. [0034]: At block 238, method 230 includes moving the number of wireless nodes to a second set of locations that is in communication with the root access point at the particular location), wherein each of the two or more devices is configured to transmit an RF signal of a form typically transmitted by an AP to the other T/R device which measures the received RF signal as an indication of the wireless AP transmission characteristics of RF signals transmitted between the two or more devices at the plurality of different locations within the site (see Mahasenan, Figs. 1 and 2, par. [0032]: At block 236, method 230 includes receiving communication metrics from the number of wireless nodes at the first set of locations and the root access point. Receiving communication metrics can include sending and/or receiving a number of beacon messages between the number of wireless nodes. The sending and/or receiving the number of beacon messages between the number of wireless nodes can be used to determine communication metrics between the number of wireless nodes, and see par. [0035]: At block 240, method 230 includes receiving communication metrics from the number of wireless nodes at the second set of locations and the root access point. Receiving communication metrics from the number of wireless nodes can include determining the communication metrics by analyzing sent and received beacon messages between the number of wireless nodes and between the number of wireless nodes and a computing device; in this case, RF signals are sent for determining communication metrics (i.e. for measuring the signal as an indication of the wireless AP transmission characteristics) at several locations);
causing the two or more devices to begin measuring the wireless network AP transmission characteristics at the plurality of locations within the site (see Mahasenan, Figs. 1 and 2, par. [0032]: At block 236, method 230 includes receiving communication metrics from the number of wireless nodes at the first set of locations and the root access point. Receiving communication metrics can include sending and/or receiving a number of beacon messages between the number of wireless nodes. The sending and/or receiving the number of beacon messages between the number of wireless nodes can be used to determine communication metrics between the number of wireless nodes, and see par. [0035]: At block 240, method 230 includes receiving communication metrics from the number of wireless nodes at the second set of locations and the root access point. Receiving communication metrics from the number of wireless nodes can include determining the communication metrics by analyzing sent and received beacon messages between the number of wireless nodes and between the number of wireless nodes and a computing device; in this case, RF signals are sent for determining communication metrics (i.e. for measuring the wireless network AP transmission characteristics) at several locations);
generating an AP installation map (see Mahasenan, Fig. 2, par. [0039]: At block 242, method 230 includes generating a node coverage map based on the received communication metrics, wherein the node coverage map includes the first and second set of locations. The received communication metrics from the number of wireless nodes can be used to generate the node coverage map. The node coverage map can include a heat map that can represent communication metrics for an area that includes the first location and the second location. The heat map can be a graphical representation of the various communication metrics for an area surrounding the first location and the second location)
However Mahasenan does not teach:
determining when a data set representative of the measured wireless network AP transmission characteristics in the site has been collected that meets a set of criteria for minimum data set characteristics; and
generating an AP installation map based on the collected data set when the set of criteria has been met.
Kasch, in the same field of endeavor, teaches:
determining when a data set representative of the measured wireless network AP transmission characteristics in the site has been collected that meets a set of criteria for minimum data set characteristics (see Kasch, Fig. 3, par. [0037]: Operations 302-306 (or a subset of these operations) may be repeated a number of times depending on the number of available sensors and/or the size of the deployment area, until the coverage is fully mapped for the entire deployment area. The process of measuring the coverage and signal quality for the deployment area is discussed in additional detail in copending application Ser. No. 14/506,106, which is hereby incorporated by reference into the present specification. Once the signal measurements of the deployment area are complete, a heatmap or other visual representation of the signal quality and coverage may be generated and displayed to the user; in this case, measurements of coverage and signal quality (corresponding to wireless network AP transmission characteristics) are performed until coverage is fully mapped and signal measurements are complete (corresponding to determining when a set of criteria is met for minimum data set characteristics)); and
generating an AP installation map based on the collected data set when the set of criteria has been met (see Kasch, Fig. 3, par. [0037]: Operations 302-306 (or a subset of these operations) may be repeated a number of times depending on the number of available sensors and/or the size of the deployment area, until the coverage is fully mapped for the entire deployment area. The process of measuring the coverage and signal quality for the deployment area is discussed in additional detail in copending application Ser. No. 14/506,106, which is hereby incorporated by reference into the present specification. Once the signal measurements of the deployment area are complete, a heatmap or other visual representation of the signal quality and coverage may be generated and displayed to the user, and see par. [0046]: Once all necessary simulations have been completed, access point locations and configurations can be presented to the user at operation 310. In some embodiments, a heatmap is presented showing the signal coverage for the deployment area together with the original access point locations, the new access point locations, and a channel assignment for each access point; in this case, a heatmap with access point locations corresponds to an AP installation map. The heatmap is generated after collecting all the measurements (i.e. when the set of criteria has been met)).
Therefore, it would have been obvious to one of ordinary skill in the art, before the effective filing date of the claimed invention, to have modified the method of Mahasenan with the determining meeting a set of criteria for measurements and generating an AP installation map when meeting the criteria of Kasch with a reasonable expectation of success. One of ordinary skill in the art would have been motivated to make this modification for the benefit of maximizing signal coverage in a site (see Kasch, par. [0015]).
Regarding claim 2, the combination of Mahasenan in view of Kasch teaches the method.
Mahasenan does not teach, but Kasch teaches:
the steps of causing the devices to begin mapping and determining when a data set has met the set of criteria are carried out by a command device (see Kasch, Figs. 3 and 5, par. [0049]: processor 502, whether configured through hardware or through execution of program instructions stored in memory 504, may be configured to perform and/or control performance of operations in accordance with various embodiments disclosed herein. Display 508 is operable to display a user interface allowing a user to view signal data from sensors such as sensor 400, proposed access point locations, and estimated signals strength data, as well as to enter data such as that relating to actual access point and sensor locations. The operation of and information displayed by display 508 is discussed in greater detail above with respect to method 300, and see par. [0037]: Operations 302-306 (or a subset of these operations) may be repeated a number of times depending on the number of available sensors and/or the size of the deployment area, until the coverage is fully mapped for the entire deployment area. The process of measuring the coverage and signal quality for the deployment area is discussed in additional detail in copending application Ser. No. 14/506,106, which is hereby incorporated by reference into the present specification. Once the signal measurements of the deployment area are complete, a heatmap or other visual representation of the signal quality and coverage may be generated and displayed to the user; in this case, the controller device in Fig. 5 performs the method of Fig. 3, which includes performing measurements for mapping and determining when measurements are complete ((corresponding to determining when a set of criteria is met for minimum data set characteristics)), and wherein the command device further provides instructions to a user for repositioning at least one of the two or more devices after readings at a location pair are taken (see Kasch, Figs. 3 and 5, par. [0049]: processor 502, whether configured through hardware or through execution of program instructions stored in memory 504, may be configured to perform and/or control performance of operations in accordance with various embodiments disclosed herein. Display 508 is operable to display a user interface allowing a user to view signal data from sensors such as sensor 400, proposed access point locations, and estimated signals strength data, as well as to enter data such as that relating to actual access point and sensor locations. The operation of and information displayed by display 508 is discussed in greater detail above with respect to method 300, and see par. [0037]: Operations 302-306 (or a subset of these operations) may be repeated a number of times depending on the number of available sensors and/or the size of the deployment area, until the coverage is fully mapped for the entire deployment area. The process of measuring the coverage and signal quality for the deployment area is discussed in additional detail in copending application Ser. No. 14/506,106, which is hereby incorporated by reference into the present specification. Once the signal measurements of the deployment area are complete, a heatmap or other visual representation of the signal quality and coverage may be generated and displayed to the user; in this case, the controller device in Fig. 5 performs the method of Fig. 3 which includes repeatedly determining recommended placements (i.e. instructing a user for repositioning)).
Therefore, it would have been obvious to one of ordinary skill in the art, before the effective filing date of the claimed invention, to have modified the method of Mahasenan with the command device performing the steps of Kasch with a reasonable expectation of success. One of ordinary skill in the art would have been motivated to make this modification for the benefit of maximizing signal coverage in a site (see Kasch, par. [0015]).
Regarding claim 3, the combination of Mahasenan in view of Kasch teaches the method.
Mahasenan does not teach, but Kasch teaches:
wherein the command device further provides real-time feedback and instructions to the user based on the collected data set (see Kasch par. [0046]: Once all necessary simulations have been completed, access point locations and configurations can be presented to the user at operation 310. In some embodiments, a heatmap is presented showing the signal coverage for the deployment area together with the original access point locations, the new access point locations, and a channel assignment for each access point; in this case, access point locations and configurations correspond to real-time feedback and instructions).
Therefore, it would have been obvious to one of ordinary skill in the art, before the effective filing date of the claimed invention, to have modified the method of Mahasenan with the feedback and instructions of Kasch with a reasonable expectation of success. One of ordinary skill in the art would have been motivated to make this modification for the benefit of maximizing signal coverage in a site (see Kasch, par. [0015]).
Regarding claim 5, the combination of Mahasenan in view of Kasch teaches the method. Mahasenan further teaches:
wherein the AP transmission characteristics include the strength of transmitted and received RF signals at the various locations within the site (see Mahasenan, Figs. 1 and 2, par. [0032]: At block 236, method 230 includes receiving communication metrics from the number of wireless nodes at the first set of locations and the root access point. Receiving communication metrics can include sending and/or receiving a number of beacon messages between the number of wireless nodes. The sending and/or receiving the number of beacon messages between the number of wireless nodes can be used to determine communication metrics between the number of wireless nodes, and see par. [0007]: A wireless network site survey can be used to determine a number of communication metrics (e.g., connection qualities, received signal strength indication (RSSI), link quality indicator (LQI), received signal quality indicator (RSQI), etc.) for a wireless network)
Mahasenan does not teach, but Kasch teaches:
the T/R devices include a power sensor configured to measure and record the strength of transmitted and received RF signals (see Kasch, Fig. 4, par. [0048]: Sensor device 408 may be a wireless communications interface or may be a dedicated sensor operable to collect a wide variety of data regarding electromagnetic signal in the vicinity of sensor 400. For example, sensor device 4088 the signal strength from one or more nearby access points, a noise level on one or more frequencies or channels, or any other information).
Therefore, it would have been obvious to one of ordinary skill in the art, before the effective filing date of the claimed invention, to have modified the method of Mahasenan with the power sensor of Kasch with a reasonable expectation of success. One of ordinary skill in the art would have been motivated to make this modification for the benefit of maximizing signal coverage in a site (see Kasch, par. [0015]).
Regarding claim 7, the combination of Mahasenan in view of Kasch teaches the method.
Mahasenan does not teach, but Kasch teaches:
wherein the AP transmission characteristics further comprise at least one of a throughput, a signal-to-noise ratio, and interference levels at the plurality locations within the site (see Kasch, par. [0036]: Sensors 218 may utilize a variety of metrics to measure coverage. For example, sensors 218 might measure the raw signal-to-noise ratio (SNR) for a given channel or frequency. Alternatively, the sensors might measure one or more higher-level network characteristics directly. For example, throughput, latency, jitter, and/or congestion might be measured under a given work load to measure the coverage).
Therefore, it would have been obvious to one of ordinary skill in the art, before the effective filing date of the claimed invention, to have modified the characteristics of Mahasenan with the specific characteristics of Kasch with a reasonable expectation of success. One of ordinary skill in the art would have been motivated to make this modification for the benefit of maximizing signal coverage in a site (see Kasch, par. [0015]).
Regarding claim 8, the combination of Mahasenan in view of Kasch teaches the method.
Mahasenan does not teach, but Kasch teaches:
wherein the T/R devices are capable of communicating with each other using a variety of RF wavelengths (see Kasch, par. [0025]: each access point will typically operate on one of a fixed number of channels or frequencies).
Therefore, it would have been obvious to one of ordinary skill in the art, before the effective filing date of the claimed invention, to have modified the method of Mahasenan with the variety of RF wavelengths of Kasch with a reasonable expectation of success. One of ordinary skill in the art would have been motivated to make this modification for the benefit of maximizing signal coverage in a site (see Kasch, par. [0015]).
Regarding claim 9, the combination of Mahasenan in view of Kasch teaches the method. Mahasenan further teaches:
wherein the T/R devices can selectively switch between transmitter and receiver roles to mimic the interaction between access points and client devices within the wireless network (see Mahasenan, Figs. 1 and 2, par. [0032]: At block 236, method 230 includes receiving communication metrics from the number of wireless nodes at the first set of locations and the root access point. Receiving communication metrics can include sending and/or receiving a number of beacon messages between the number of wireless nodes. The sending and/or receiving the number of beacon messages between the number of wireless nodes can be used to determine communication metrics between the number of wireless nodes; in this case, the nodes used for measuring can both send and receive messages with each other, corresponding to switching between transmitter and receiver roles).
Regarding claim 11, Mahasenan teaches:
A system for assisted private wireless network access point (AP) placement, comprising:
two or more devices equipped with radio frequency (RF) transmitter and receiver functionality, these devices (T/R devices) being capable of repositioning throughout various locations within a site to measure the AP transmission characteristics of RF signals (see Mahasenan, Figs. 1 and 2, par. [0030]: At block 232, method 230 includes placing a number of wireless nodes at a first set of locations. The number of wireless nodes can include nodes that are capable of sending and/or receiving wireless messages, and see par. [0034]: At block 238, method 230 includes moving the number of wireless nodes to a second set of locations that is in communication with the root access point at the particular location, and see par. [0032]: At block 236, method 230 includes receiving communication metrics from the number of wireless nodes at the first set of locations and the root access point. Receiving communication metrics can include sending and/or receiving a number of beacon messages between the number of wireless nodes. The sending and/or receiving the number of beacon messages between the number of wireless nodes can be used to determine communication metrics between the number of wireless nodes, and see par. [0035]: At block 240, method 230 includes receiving communication metrics from the number of wireless nodes at the second set of locations and the root access point. Receiving communication metrics from the number of wireless nodes can include determining the communication metrics by analyzing sent and received beacon messages between the number of wireless nodes and between the number of wireless nodes and a computing device; in this case, RF signals are sent for determining communication metrics (i.e. for measuring the signal as an indication of the wireless AP transmission characteristics) at several locations);
However, Mahasenan does not teach:
a command device configured to cause a processor within each T/R device to direct the T/R device to reposition its location throughout the site, the command device further being programmed with criteria for assessing whether a data set representative of wireless network AP transmission characteristics meets predetermined minimum requirements.
Kasch, in the same field of endeavor, teaches:
a command device configured to cause a processor within each T/R device to direct the T/R device to reposition its location throughout the site (see Kasch, Figs. 3 and 5, par. [0049]: processor 502, whether configured through hardware or through execution of program instructions stored in memory 504, may be configured to perform and/or control performance of operations in accordance with various embodiments disclosed herein. Display 508 is operable to display a user interface allowing a user to view signal data from sensors such as sensor 400, proposed access point locations, and estimated signals strength data, as well as to enter data such as that relating to actual access point and sensor locations. The operation of and information displayed by display 508 is discussed in greater detail above with respect to method 300, and see par. [0037]: Operations 302-306 (or a subset of these operations) may be repeated a number of times depending on the number of available sensors and/or the size of the deployment area, until the coverage is fully mapped for the entire deployment area. The process of measuring the coverage and signal quality for the deployment area is discussed in additional detail in copending application Ser. No. 14/506,106, which is hereby incorporated by reference into the present specification. Once the signal measurements of the deployment area are complete, a heatmap or other visual representation of the signal quality and coverage may be generated and displayed to the user; in this case, the controller device in Fig. 5 performs the method of Fig. 3 which includes repeatedly determining recommended placements (i.e. instructing a user for repositioning)), the command device further being programmed with criteria for assessing whether a data set representative of wireless network AP transmission characteristics meets predetermined minimum requirements (see Kasch, Figs. 3 and 5, par. [0049]: processor 502, whether configured through hardware or through execution of program instructions stored in memory 504, may be configured to perform and/or control performance of operations in accordance with various embodiments disclosed herein. Display 508 is operable to display a user interface allowing a user to view signal data from sensors such as sensor 400, proposed access point locations, and estimated signals strength data, as well as to enter data such as that relating to actual access point and sensor locations. The operation of and information displayed by display 508 is discussed in greater detail above with respect to method 300, and see par. [0037]: Operations 302-306 (or a subset of these operations) may be repeated a number of times depending on the number of available sensors and/or the size of the deployment area, until the coverage is fully mapped for the entire deployment area. The process of measuring the coverage and signal quality for the deployment area is discussed in additional detail in copending application Ser. No. 14/506,106, which is hereby incorporated by reference into the present specification. Once the signal measurements of the deployment area are complete, a heatmap or other visual representation of the signal quality and coverage may be generated and displayed to the user; in this case, the controller device in Fig. 5 performs the method of Fig. 3, which includes performing measurements for mapping and determining when measurements are complete ((corresponding to determining when a set of criteria is met for minimum data set characteristics)).
Therefore, it would have been obvious to one of ordinary skill in the art, before the effective filing date of the claimed invention, to have modified the system of Mahasenan with the command device performing the steps of Kasch with a reasonable expectation of success. One of ordinary skill in the art would have been motivated to make this modification for the benefit of maximizing signal coverage in a site (see Kasch, par. [0015]).
Regarding claim 15, the combination of Mahasenan in view of Kasch teaches the system.
Mahasenan does not teach, but Kasch teaches:
wherein the T/R devices further comprise a power sensor that measures and records RF signal strength at the various locations throughout the site (see Kasch, Fig. 4, par. [0048]: Sensor device 408 may be a wireless communications interface or may be a dedicated sensor operable to collect a wide variety of data regarding electromagnetic signal in the vicinity of sensor 400. For example, sensor device 4088 the signal strength from one or more nearby access points, a noise level on one or more frequencies or channels, or any other information, and see par. [0037]: Operations 302-306 (or a subset of these operations) may be repeated a number of times depending on the number of available sensors and/or the size of the deployment area, until the coverage is fully mapped for the entire deployment area. The process of measuring the coverage and signal quality for the deployment area is discussed in additional detail in copending application Ser. No. 14/506,106, which is hereby incorporated by reference into the present specification. Once the signal measurements of the deployment area are complete, a heatmap or other visual representation of the signal quality and coverage may be generated and displayed to the user).
Therefore, it would have been obvious to one of ordinary skill in the art, before the effective filing date of the claimed invention, to have modified the T/R devices of Mahasenan with the power sensor of Kasch with a reasonable expectation of success. One of ordinary skill in the art would have been motivated to make this modification for the benefit of maximizing signal coverage in a site (see Kasch, par. [0015]).
Regarding claim 16, the combination of Mahasenan in view of Kasch teaches the system.
Mahasenan does not teach, but Kasch teaches:
wherein the power sensor readings contribute to determining optimal wireless network access point locations based on signal coverage and performance metrics (see Kasch, Fig. 4, par. [0048]: Sensor device 408 may be a wireless communications interface or may be a dedicated sensor operable to collect a wide variety of data regarding electromagnetic signal in the vicinity of sensor 400. For example, sensor device 4088 the signal strength from one or more nearby access points, a noise level on one or more frequencies or channels, or any other information, and see par. [0037]: Operations 302-306 (or a subset of these operations) may be repeated a number of times depending on the number of available sensors and/or the size of the deployment area, until the coverage is fully mapped for the entire deployment area. The process of measuring the coverage and signal quality for the deployment area is discussed in additional detail in copending application Ser. No. 14/506,106, which is hereby incorporated by reference into the present specification. Once the signal measurements of the deployment area are complete, a heatmap or other visual representation of the signal quality and coverage may be generated and displayed to the user, and see par. [0046]: Once all necessary simulations have been completed, access point locations and configurations can be presented to the user at operation 310. In some embodiments, a heatmap is presented showing the signal coverage for the deployment area together with the original access point locations, the new access point locations, and a channel assignment for each access point).
Therefore, it would have been obvious to one of ordinary skill in the art, before the effective filing date of the claimed invention, to have modified the system of Mahasenan with the power sensor of Kasch with a reasonable expectation of success. One of ordinary skill in the art would have been motivated to make this modification for the benefit of maximizing signal coverage in a site (see Kasch, par. [0015]).
Regarding claim 17, the combination of Mahasenan in view of Kasch teaches the system.
Mahasenan does not teach, but Kasch teaches:
wherein the T/R devices are configured to measure and record additional RF signal characteristics, including throughput, signal-to-noise ratio, and interference levels at different site locations (see Kasch, par.

Alternatively, the sensors might measure one or more higher-level network characteristics directly. For example, throughput, latency, jitter, and/or congestion might be measured under a given work load to measure the coverage).
Therefore, it would have been obvious to one of ordinary skill in the art, before the effective filing date of the claimed invention, to have modified the characteristics of Mahasenan with the specific characteristics of Kasch with a reasonable expectation of success.

One of ordinary skill in the art would have been motivated to make this modification for the benefit of maximizing signal coverage in a site (see Kasch, par. [0015]).
Regarding claim 19, the combination of Mahasenan in view of Kasch teaches the system. Mahasenan further teaches:

[0032]: At block 236, method 230 includes receiving communication metrics from the number of wireless nodes at the first set of locations and the root access point. Receiving communication metrics can include sending and/or receiving a number of beacon messages between the number of wireless nodes. The sending and/or receiving the number of beacon messages between the number of wireless nodes can be used to determine communication metrics between the number of wireless nodes; in this case, the nodes used for measuring can both send and receive messages with each other, corresponding to switching between transmitter and receiver roles).

Egner, in the same field of endeavor, teaches:
further including a step of having the command device transmit the data set to an external server (see Egner, par. [0019]: The WLAN AP base transceiver location optimization system of various embodiments of the present disclosure may operate in some example embodiments as a software agent, in whole or in part, within a WLAN AP or other wireless network access point while other portions of the WLAN AP base transceiver location optimization system may operate on remote server systems, and see par. [0048]: in FIG. 4 at arrow 406, the WLAN AP base transceiver location optimization system 126 and may receive a neighborhood radio frequency (RF) traffic report data from the unlicensed small cell WWAN base station 204 detailing the identifications, operating channels, traffic load, signal strength, and locations of all unlicensed small cell WWAN base stations known to the unlicensed small cell WWAN base station 204, and see par. [0048]: the WLAN AP base transceiver location optimization system 126 may receive a similar RF traffic report from each of the plurality of unlicensed small cell WWAN base stations 204-226 in the wireless network; in this case, the optimization system may be run on a server and may receive traffic reports (i.e. data sets) from the APs (i.e. the command device transmits to the server)), wherein the step of generating the AP installation map based on the collected data set is carried out by the external server (see Egner, Fig. 5, par. [0087]: At block 516, the WLAN AP base transceiver location optimization system in an embodiment may transmit machine-readable code instructions to the WLAN AP to instruct the digital display to display a graphical indicator of a direction pointing toward the optimal geographic location. For example, with reference to FIG. 4, at arrow 414, the WLAN AP base transceiver location optimization system may transmit code instructions to the WLAN AP 202 instructing its digital display 110 to display an arrow 420 indicating a direction (shown here as an arrow) pointing toward the optimal geographic location 408; in this case, a graphical representation of optimal location corresponds to an AP installation map), and wherein the AP transmission characteristics readings are used by the external server to determine optimal locations for the placement of wireless network with the AP installation map based on signal coverage and network performance criteria (see Egner, Fig. 5, par.

As described above, situating BTS systems (including both WLAN AP and unlicensed small cell WWAN base stations) geographically close to one another may yield direct interference among the BTS systems, and may increase roll-off into adjacent radio channel frequencies, causing further interference. As also described above, many installers of WLAN AP base transceiver stations are not technologically proficient enough to identify an optimal geographic location for a WLAN AP operating geographically close to one or more unlicensed small cell WWAN base stations. The WLAN AP base transceiver location optimization system operates to identify the optimal geographic location and communicate that location to the installer; in this case, interference and optimal AP location are determined based on signal coverage and network performance using measurements).

Therefore, it would have been obvious to one of ordinary skill in the art, before the effective filing date of the claimed invention, to have modified the method of Mahasenan with the command device of Kasch with a reasonable expectation of success. One of ordinary skill in the art would have been motivated to make this modification for the benefit of maximizing signal coverage in a site (see Kasch, par. [0015]).
However, the combination of Mahasenan in view of Kasch does not teach:
