Channel center frequencies are defined at every integer multiple of 5 MHz above the cha1111el starting 

frequency. The relationship between center frequency and ch31111el number is gi\·en by Equation {17-27): 

Ch31111el center frequency = Ch31111el starting frequency + 5 x nch (MHz) {l 7-27) 

where 

Channel starting frequency is defined as dotl IChannelStartingfactor x 500 kHz or 

is defined as 5 GHz for systems where dotl I OperatingClassesRequired is 

false or not defined. 

For example, dotl l ChannelStartingFactor = 10000 indicates that Channel 0 center frequency is 5.000 GHz. 

A cha1111el center frequency of 5.000 GHz shall be indicated by dotl l Channe!Startingf actor = 8000 and

J_ We authorize two different types of unlicen ed operations- standard-power and indoor 

tow-power operations. We authorize standard-power access points using an automated frequency 

coordination (AFC) y tern. These acces points can be deployed anywhere as part of hotspot networks, 

rural broadband deployments, or network capacity upgrades where needed. We also authorize indoor 

low-power access points across the entire 6 Gllz band. These access points wilt be ideal for connecting 

devices in homes and businesses such smartphones, tablet devices, laptops, and Internet-of-things (loT) 

devices to the Internet. As has occurred with Wi-Fi in the 2.4 GI lz and 5 GHz bands, we expect that 6 

Gt lz unlicensed devices will become a part of most peoples' everyday lives. The rules we are adopting 

will also play a role in the growth of the loT; connecting appliances, machines, meters, wearables, and 

other consumer electronics as well as industrial sensors for manufacturing.4

Identification 

The WiFi 6 standard includes the HE spatial reuse operation, in which the same frequency channel of the plurality 

of frequency channels is provided in two or more adjacent portions of the service area. 

For example, this is used for different basic service sets (BSS) to operate within a dense enviromnent. Stations 

(STA) identify whether physical layer protocol data units (PPDUs) originate from within their own BSS when the 

sets are overlapping. 

T.6 BSS color and spatial reuse 

rThe BSS color is an identifier of the BSS and is used to assist a receiYing ST A in identifying the BSS from 

M"hich a PPDU originates so that the STA can follow the cham1el access mies to pe1fom1 spatial reuse. The 

~bjectiYe of spatial reuse operation is to allow the medimn to be used more often between OBSSs in dense 

kteployment scenarios by the early identification of signals from OBSSs and inteiierence management.

true: 

- The RXVECTOR parameter BSS _ COLOR is not 0 and is not the BSS color of the BSS of ,vhich the 

ST A is a member. 

A STA shall classify the received PPDU as an intra-BSS PPDU if at least one of the following conditions is 

true: 

- The RXVECTOR parameter BSS _ COLOR of the PPDU can-ying the frame is the BSS color of U1e 

BSS of which the ST A is a member or the BSS color of any TDLS links to which the ST A belongs

• Select the Keep my channel selection during power cyde 

check box to save your channel selection when your 

Verizon Router is rebooted. 

• Enable DFS channels during channel scan: DFS channels 

are enabled by default during channel scans. 

Note: DFS channels are a subset of the 5 GHz network that 

is shared with radar systems. Some consumer devices do 

not support these channels and cannot connect to routers 

using them. Examples include some media streaming devices. 

Disabling this feature will allow the router to select the best 

available channel to broadcast on and allow these devices to 

connect.

The second tier of the scheduling strategy is to allocate the assigned frequency channels resulting from the first tier 

of the scheduling strategy among the network nodes disposed in each po1tion of the service area in real-time,

Through the spatial reuse operation, frequency channels are allocated by BSS color (marking PPDUs as inter-BSS).
