C-band frequency

The c band frequency is transmitted from 3.7 to 4.2 GHz in two tranches. The first 100 MHz is currently available in 50 markets in the United States, covering approximately 60% of the American population. Verizon and AT&T share the 60/40 "Block A" airwaves. So Verizon would be on top, and AT&T on the bottom, the 50 MHz rule of thumb that I use for real 5G differentiation.

Another 180 MHz is expected to be released at the end of 2023. That includes a lot of Verizon and AT&T spectrum, as well as wireless spectrum purchased by T-Mobile, US Cellular and some other phone companies. At that time, Verizon will end up with an average of 160 MHz of spectrum and AT&T with an average of 80 MHz, both of which could offer a truly different 5G experience.

 The program provides for the launch of these networks at the end of 2023 or 2024. These launches may, however, earlier in 2023, if the standards of the 600 MHz band are maintained. T-Mobile took over a large part of the 600 MHz band, which used to be TV channels 14 to 55, in 2017. This has a license that extends until July 2020. But T-Mobile works with broadcasters (and pays) to get licenses early, getting licenses from New York City more than a year ahead of schedule, for example.

AT&T, Dish and T-Mobile are the customers of the 3.45 GHz frequency. AT&T and Dish said they plan to turn them on as soon as the equipment is available, either later in 2022 or early 2023. T-Mobile is keeping its 3.45 GHz for when it needs the license.

 

CIENA NETWORKS THE OCEAN FLOOR

 Southern Cross is an independent company that provides capacity, mostly undersea, to network operators and their ISPs in Australia, New Zealand and the Asia-Pacific region. Shareholders include New Zealand's Spark provider, Australia's Singtel Optus, Verizon (NYSE: VZ) and Telstra. 

Southern Cross's key projects was his just-announced NEXT cable. It operates between Sydney, Auckland and Los Angeles, with fiber optic connections to the islands of Tokelau, Kiribati and Fiji. NEXT took two years to complete and is one of three cable systems that will form the Southern Cross ecosystem in the Asia-Pacific region.

Ciena networks are leading optical networking company, provided the underwater switching technology that forms the basis of NEXT. The switch implemented was a WaveLogic 5 Extreme (WL5e) model with coherent optics, a laser designed to transmit large amounts of data over long distances. WL5e connections operate at speeds of up to 800 Gbps and are used in the networks of Comcast, Deutsche Telekom, Spark, Sparkle, Telus, Verizon, Vodafone New Zealand, and Windstream, to name a few. The

Cienas WL5e was the provider's platform for operating his GeoMesh Extreme technology and connected the rest of the cables in the Southern Cross ecosystem to his NEXT. As the name suggests, GeoMesh creates a network between terrestrial and subsea connections. This is more difficult than it sounds. The optical signal is a type of packet used on land using technology that is routed over an undersea link from an inland terrestrial Point of Presence (PoP), rather than from a hut on the shore, and is deployed under the waves. Must support exchange.

GeoMesh uses artificial intelligence (AI), monitoring and telemetry, software-defined networking (SDN), integration testing, and other measures to track network performance and prevent fiber damage from passing ships or tsunamis. Fix the unavoidable errors that occur when etc. will be interrupted. and other marine threats.
