Office Action

§103
DETAILED ACTION In response to communication filed on 7/9/2026. Claims 1-11 and 23-32 are pending. Claims 1-11 and 23-32 are rejected. Notice of Pre-AIA or AIA Status The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Continued Examination Under 37 CFR 1.114 A request for continued examination under 37 CFR 1.114, including the fee set forth in 37 CFR 1.17(e), was filed in this application after final rejection. Since this application is eligible for continued examination under 37 CFR 1.114, and the fee set forth in 37 CFR 1.17(e) has been timely paid, the finality of the previous Office action has been withdrawn pursuant to 37 CFR 1.114. Applicant's submission filed on 7/9/2026 has been entered. Response to Amendments This communication is in response to Applicant’s reply filed under 3 CFR 1.111 on 7/9/2026. Claims 1 and 8 were amended, claims 12-22 were canceled, claims 23-32 were added and claims 1-11 and 23-32 remain pending. Claim Rejections - 35 USC § 103 The text of those sections of Title 35, U.S. Code not included in this action can be found in a prior Office action. Claims 1,5,6,8,23-27, and 30-32 are rejected under 35 U.S.C. 103 as being unpatentable over Nair et al. (US Pub. 2022/038118)(N1 hereafter) in view of Anchala et al. (US Pub. 2024/0048256)(A1 hereafter). Regarding claim 1, N1 teaches a wireless network optimization system [refer Fig. 1; 115][paragraph 0068] comprising: a communication interface (i.e. antenna)[refer Fig. 1; 113] to receive data associated with a wireless network operational area while moving along a survey path through the wireless network operational area (a device can be on a vehicle and can move within an environment capturing transmitted signals to generate channel responses)[paragraph 0098], the data including one or more signal characteristic measurement values [paragraph 0115]; and a controller (i.e. processor)[paragraph 0047] to: train a machine learning model [paragraph 0049], based at least partially on the data [paragraph 0088]. However, N1 fails to disclose building a signal propagation model for the wireless network operational area, the signal propagation model built using the trained machine learning model, the signal propagation model is configured to estimate signal propagation at locations within the wireless network operational area beyond the survey path along which the one or more signal characteristic measurement values were obtained. A1, in the field of tuning a wireless network propagation model, for each location, a process can compare signal measurements from crowdsourced data with signal measurements predicted in the propagation model and can adjust the model to accurately represent network coverage in an area [paragraph 0035], when the predicted signal measurements of the propagation model at locations are outside of a predetermined range of the crowdsourced data measurements at those locations, the nominal propagation model is tuned with the collected crowdsourced data to more accurately simulate the network coverage provided to the coverage area and can predict signal strength at particular locations (i.e. beyond surveyed area)[paragraph 0036]. It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the teachings of N1 for training a channel decoder network to adjust variables over time to mirror the evolution of propagation effects [refer N1; paragraph 0086] to incorporate the collection of data and tuning of a wireless network propagation model for locations as taught by A1. One would be motivated to do so to improve quality of service [refer A1; paragraph 0036]. Regarding claim 5, N1 fails to disclose the controller further: estimates a location of one or more access points in the wireless network operational area, based at least partially on one or more Received Signal Strength Indicator (RSSI) measurements included in the data, and trains the machine learning model, based at least partially on the location of the one or more access points. A1, in the field of tuning a wireless network propagation model, for each location, a process can compare signal measurements from crowdsourced data with signal measurements predicted in the propagation model and can adjust the model to accurately represent network coverage in an area [paragraph 0035], such that collecting data for network performance, a device can collect RF signal measurements, such as signal strength, from various locations [paragraph 0029]. It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the teachings of N1 for training a channel decoder network to adjust variables over time to mirror the evolution of propagation effects [refer N1; paragraph 0086] to incorporate the collection of data and tuning of a wireless network propagation model for locations as taught by A1.

Regarding claim 6, N1 teaches the controller further trains the machine learning model, based at least partially on a transmit power of one or more access points in the wireless network operational area (channel responses for signal approximation represent values of power received at different delays form one or more antennas)[paragraph 0063]. Regarding claim 8, N1 fails to disclose the signal propagation model covers a requirement area larger than the survey path along which the data is obtained. A1, in the field of tuning a wireless network propagation model, for each location, a process can compare signal measurements from crowdsourced data with signal measurements predicted in the propagation model and can adjust the model to accurately represent network coverage in an area [paragraph 0035], when the predicted signal measurements of the propagation model at locations are outside of a predetermined range of the crowdsourced data measurements at those locations, the nominal propagation model is tuned with the collected crowdsourced data to more accurately simulate the network coverage provided to the coverage area and can predict signal strength at particular locations (i.e. beyond surveyed area)[paragraph 0036]. It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to modify the teachings of N1 for training a channel decoder network to adjust variables over time to mirror the evolution of propagation effects [refer N1; paragraph 0086] to incorporate the collection of data and tuning of a wireless network propagation model for locations as taught by A1.

However, N1 fails to disclose building a signal propagation model for the wireless network operational area, the signal propagation model built using the trained machine learning model, and use the signal propagation model to simulate an effect of adding a new access point within the wireless network operational area on signal propagation.
