Claim(s) 1-20 is/are rejected under 35 U.S.C. 103 as being unpatentable over Amini et al (Amini), US 2018/0103505, in view of Liu et al (Liu), US 2019/0342916.
As per claim 1, Amini teaches the invention including a wireless component arranged in a wireless network having a current topology that enables communication with another wireless component over a backhaul link, the wireless component comprising:
A first radio operating in a first wireless band (pp. 0036, 0042);
A second radio operating in a second wireless band, the second wireless band being different from the first wireless band (pp. 0036, 0042: Fronthaul communication link can be established by access point node at the 2.4 GHz band. By contrast, backhaul communication links can be established to operate at a different band than the fronthaul communication links such as within the 5 GHz lower band); and
A control circuit configured to perform the steps of:
Detecting when a client device connects to the wireless component over a new fronthaul link (pp. 0035-0036; 0044-0047),
Determining wireless communication capabilities of the client device (pp. 0044-0047),
Based on the wireless communication capabilities, determine which one of the current topology of the wireless network and a new topology of the wireless network would result in greater throughput of packets through the wireless network (pp. 0044-0051), and
When it is determined that the new topology would result in greater throughput, adjusting the topology by designating one of the first radio and second radio form communication over the backhaul link and designating the other of the first radio and second radio for communication over the new fronthaul link (pp. 0047-0051).
Amini does not teach the wireless component, wireless network and wireless band and wireless communication to be Wi-Fi component, Wi-Fi network and Wi-Fi band and Wi-Fi communication; and wherein the backhaul link and fronthaul link are configured to operate in different Wi-Fi bands so as to enable simultaneous packet reception over the first or second Wi-Fi bands and packet transmission over the other of the first or second Wi-Fi bands without queuing packets on a same channel. However, Wi-Fi is a well-known type of wireless communication and suggested by Amini. Amini provides a motivation to implement the wireless mesh network of the invention according to IEEE 802.11 standards in WLAN, which is Wi-Fi standard known in the art (pp. 0004: IEEE 802.11 is Wi-Fi standard). Liu teaches a Wi-Fi component implemented with multi Wi-Fi band with a first radio operating in a first Wi-Fi band (pp. 0007, 0036, 0056); a second radio operating in a second Wi-Fi band, the second Wi-Fi band being different from the first Wi-Fi band (pp. 0007, 0025) for performing Wi-Fi communication over a Wi-Fi component (pp. 0007, 0025); and wherein the backhaul link and fronthaul link are configured to operate in different Wi-Fi bands so as to enable simultaneous packet reception over one of the first or second Wi-Fi bands and packet transmission over the other of the first or second Wi-Fi bands without queuing packets on a same channel (pp. 0007, 0025-0027; simultaneously receive from and transmit to). It would have been obvious to one of ordinary skill in the art at the time the invention was filed to combine the teachings of Amini and Liu and further implement the system with dual Wi-Fi baseband processors to process egress and ingress traffic concurrently using different Wi-Fi bands such as 900 MHz, 2.4 GHz, 3.6 GHz, 5 GHz bands…etc.
As per claim 2, Amini and Liu teach the invention as claimed in claim 1. Amini further teaches wherein the control circuit is configured to cause the first radio to operate at a first channel in the first Wi-Fi band and cause the second radio to operate at a second channel in the second Wi-Fi band (pp. 0004, 0008, 0038, 0040-0041).
As per claim 3, Amini and Liu teach the invention as claimed in claim 1. Liu further teaches wherein the first Wi-Fi band includes the 5GHz band (pp. 0025-0027, 0036) and second Wi-Fi band includes the 6GHz band (pp. 0025-0027). Amini and Liu do not teach wherein the first Wi-Fi band includes at least a portion of the 5GHz band as defined in Wi-Fi 6E and Wi-Fi 7 standards and the second Wi-Fi band includes at least a portion of the 6 GHz band as defined in the Wi-Fi 6E and Wi-Fi 7 standards. However, since Wi-Fi 6E and Wi-Fi 7 standards are available at the time of the filing of this application, it would have been obvious to one of ordinary skill in the art at the time the invention was filed to combine the teachings of Amini, Liu and further implement the latest version of IEEE 802.11 to operate the Wi-Fi communication using different bands.
As per claim 4, Amini and Liu teach the invention as claimed in claim 3. Amini and Liu do not teach wherein:
When the control circuit determines that the Wi-Fi communication capabilities of the client device allows operations in the 6 GHz band, the control circuit is configured to designate the first radio for communication over the backhaul link and designate the second radio for communication over the new fronthaul link, and
When the control circuit determines that the Wi-Fi communication capabilities of the client device do not allow operation in the 6 GHz band, the control circuit is configured to designate the second radio communication over the backhaul link and designate the first radio for communication over the new fronthaul link.
However, it is obvious to first determine if the client device has the capability to support 6 GHz band transmission before designating the 6 GHz band radio for communication over such link or otherwise designate another radio which the client device supports in order to perform the communication properly and maintain or increase throughput. It would have been obvious to one of ordinary skill in the art at the time the invention was filed to combine the teachings of Amini and Liu and further check to determine if the client device is able to support certain frequency band transmission or not before allocating the link with said frequency band to the client device for transmission and ensure the communication thereof is performed efficiently.
As per claim 5, Amini and Liu teach the invention as claimed in claim 1. Amini further teaches to comprise a third radio operating a third Wi-Fi band that is different from the first and second Wi-Fi bands (pp. 0036, 0048: 2.4 GHz, 5 GHz upper, and 5 GHz lower). Amini and Liu do not teach the third radio is configured for communication over one or more additional fronthaul links. However, it is obvious to establish more than one fronthaul link to a network component for different types of communications. It would have been obvious to one of ordinary skill in the art at the time the invention was filed to combine the teaching of Amini and Liu and further establish multiple fronthaul links to communicate different types of data to other network devices.
As per claim 6, Amini and Liu teach the invention as claimed in claim 1. Amini further teaches to comprise an adjustable third radio operating a channel in one or more of the 2.4 GHz band, 5 GHz band (pp. 0036, 0048). Amini and Liu do not teach the third radio to operate in 6 Ghz band as defined in the Wi-Fi 6E and Wi-Fi 7 standards. However, Amini suggests to implement the wireless mesh network of the invention according to IEEE 802.11 standards in WLAN (pp. 0004: IEEE 802.11 is Wi-Fi standard). Since Wi-Fi 6E and Wi-Fi 7 standards are available at the time of the filing of this application, it would have been obvious to one of ordinary skill in the art at the time the invention was filed to combine the teachings of Amini and Liu and further implement the latest version of IEEE 802.11 to operate the Wi-Fi communication using different bands.
As per claim 7, Amini and Liu teach the invention as claimed in claim 1. Amini further teaches wherein the control circuit is configured to determine which one of the current topology and the new topology would result in greater throughput based on one or more of: multiple parallel streaming capabilities of the client device, one or more radios of the client device, a location within the Wi-Fi network or a Wi-Fi component to which the client device is connected, and a number of other client devices connected to the Wi-Fi component to which the client deice is connected (pp. 0043-0051).

As per claim 9, Amini and Liu teach the invention as claimed in claim 1. Amini further teaches wherein the Wi-Fi component is a gateway device (figure 1: AP 130 functions as a gateway connecting Internet 125).

However, notifying the nodes in the topology of the routing link changes is a common practice well known in the art to allow the nodes to update the new routing links for communication. It would have been obvious to one of ordinary skill in the art at the time the invention was filed to combine the teachings of Amini and Liu and further sends out topology change notification to all the nodes in the topology and allow routing updates of the established links.
As per claim 10, Amini and Liu teach the invention as claimed in claim 1. Amini further teaches wherein the Wi-Fi component is a leaf nod and the other Wi-Fi component is a gateway device (figure 1: AP 130 functions as a gateway connecting Internet 125).
