| T-Mobile said in October that it is expanding its LTE fixed wireless access pilot to more than 20 million households in parts of 450 cities and towns. T-Mobile’s President of Technology Neville Ray has said, “As we look ahead at driving competition, one of our major focuses is on fixed broadband. Today this is one of the most uncompetitive industries in America. Across the U.S., and in rural areas in particular, people lack options, and millions of folks are suffering from high prices and no choice. We’re going to change that.”T-Mobile isn’t just broadening its coverage to rural areas out of the goodness of its heart. The company made specific commitments to the FCC and the Department of Justice as part of the approval process for its purchase of Sprint. For example, T-Mobile has pledged to cover 85% of rural America with 5G on low-band spectrum in three years and 90% in six years.“Over time, LTE technology has advanced with features like carrier aggregation that combines different channels of spectrum so you have a fatter pipe,” said Gubbins. “When you combine that increased speed with the fact that the price of LTE technology has come down over the years, you get the kind of cost per bit that allows you to make a business case for serving these residential broadband use cases in a more reasonable way.”Many of these WISPs are founded by scrappy entrepreneurs who simply got so frustrated about the lack of internet in their area that they set up their own companies to provide it via FWA. This involves finding some vertical infrastructure, such as a water tower, to set up point-to-point or point-to-multipoint antennas to serve a several-mile area. Another critical piece of the puzzle is to access spectrum. CBRS spectrum in the 3.5 GHz band is often a good choice. And of course, there’s a need for backhaul. The WISPs can sometimes reach fiber via a telephone pole for their backhaul. But often they have to access fiber via a couple of microwave hops.Jaime Fink, VP of technology for fixed wireless at Airspan, said that Mimosa is focused on helping WISPs, DSL providers and cable operators to provide FWA. “Mimosa is extremely strong on high-performance backhaul,” said Fink. “We offer both backhaul point-to-point and edge multipoint FWA subscriber service as alternatives to mobile tech. We do this in a mix of unlicensed 5 GHz, the new 6 GHz band, and certain dedicated point-to-point licensed microwave and lower millimeter wave bands like 11 GHz and 24 GHz.” -- ???????? | |||
