Wireless LAN (WLAN) channels are frequently accessed using IEEE 802.11 protocols. The 802.11 standard provides several radio frequency bands for use in Wi-Fi communications, each divided into a multitude of channels numbered at 5 MHz spacing (except in the 45/60 GHz band, where they are 0.54/1.08/2.16 GHz apart) between the centre frequency of the channel.
Unlimited outgoing international calls to US numbers over WiFi calling. [567] [568] Yes [568] Owned by Verizon [569] Operates on Verizon's native 4G/LTE network and WiFi calling (no 3G – Verizon will shut this down at the end of 2020 anyway or roaming- some reports of LTEiRA roaming with talk and text).

Apart from their main spectrum holdings across large regions in the country (listed below) the major US carriers (AT&T, Sprint, T-Mobile & Verizon) also hold various Cellular Market Area (CMA) and/or Economic Area (EA) licenses for the AWS 1700 band, as well as Major Trading Area (MTA) and/or Basic Trading Area (BTA) licenses for the PCS 1900 band.
From Tables 5.5-1 "E-UTRA Operating Bands" and 5.6.1-1 "E-UTRA Channel Bandwidth" of the latest published version of the 3GPP TS 36.101, [1] the following table lists the specified frequency bands of LTE and the channel bandwidths each band supports.

The range originally adopted in 1945 began with channel 201 (88.1 MHz), or a value high enough to avoid confusion with television channel numbers, [2] which over the years have had values ranging from 1 to 83. Having a gap between the highest TV channel number and the lowest FM channel number allowed for expansion, which occurred in 1978 when ...
The station's virtual channel number follows the call letters. For the table for the owned-and-operated outlets, the number in parentheses that follows is the station's actual digital channel number; the digital channel number is listed as a separate column in the list of private affiliates. The article also includes a list of its former ...
