  For 5G to deliver a better experience than 4G, it needs a wide, dedicated channel, preferably 50 MHz or more. That's where C-band comes in: the frequency that can save 5G in the United States. He came. You see. The planes did not fall from the sky. AT&T and Verizon recently rolled out their C-band 5G networks after months of wrangling with airlines and the FAA. In logging, so far, we have not seen any major aviation problems or threats to aviation safety. After two years of AT&T and Verizon's "national 5G" network looking like 4G, C-band may finally increase speed. But what is C-band and what does it mean for 5G? Do you need a c band phone? Is C-band the new frequency? Should we fear group C? We can explain. Satellite recovery There is also another range of radio waves involved, from 3.45 to 3.55 GHz. No one really decided what to call them: they were "3.45", "DoD" (the military used them), or even "Andromeda". Bu...

    OPTK Networks, a Nebraska-based regional fiber optic provider, is increasing the speed capacity of its 4,000 miles of fiber optic network from 100 Gbps to 400 Gbps. This upgrade was made possible by Ciena's 6500 packet optical transport platform, which was deployed on OPTK's long-haul route from Denver to Omaha. Tim Smith, operations manager at OPTK, said the deployment will meet increasing customer demand and increase network capacity across a wider range of locations. Ciena networks 6500 hardware includes WaveLogic 5 Extreme 800G and WaveLogic Ai 400G coherent optical modems. WaveLogic 5e, launched in 2020, can send and receive up to 800G of network traffic on a single wavelength. OPTK's dark fiber, wavelength, carrier Ethernet and Internet solutions span Colorado, Nebraska and Iowa, and the company specifically serves businesses, service providers and utilities in the region. Smith said that at OPTK, the primary use case for 400G speeds "overwhelmingly...
