Telecommunication company, Sprint corporation is planning to launch a 5G network until next year, and the carrier is moving toward developing a next-generation network by releasing names of the first six cities where the company is planning to roll out Massive MIMO antenna technology: Atlanta, Chicago, Dallas, Houston, Los Angeles, and Washington, DC.
Currently, Massive Multiple inputs and multiple outputs (MIMO) is not necessary for placing 5G but it’s an important step toward reaching higher speeds and multiplying the capacity of radio links, especially at lower areas of the cellular spectrum. Latest MIMO technology uses 2X2 (where two antennas are used for sending and receiving data) or 4X4 (four antennas) arrays. Massive MIMO uses far more and the total number of antennas on Sprints arrays reaches to 128, with 64 for transmitting and 64 for receiving, which are used to enable faster speeds.
Marcelo Claure, CEO of Sprint mentioned that “We are working with Qualcomm and network and device manufacturers in order to launch the first truly mobile [5G] network in the United States by the first half of 2019, this development will put Sprint at the forefront of technology innovation on par with other leading carriers around the world. We believe our next-gen network will truly differentiate Sprint over the next couple of years. Sprint is the only carrier that doesn’t have to compromise what 5G can deliver because we can deliver super-wide channels of more than 100 MHz while still delivering mid-band coverage characteristics, we have come to an agreement with Qualcomm that they are going to be able to release this at the latter end of 2018, the new chipsets.
Meanwhile, T-Mobile is promising to build 5G infrastructure in 30 cities till the end of this year, preparing for an initial rollout of the 5G network next year. Neville Ray, Chief Technology Officer at T-Mobile quoted that “At T-Mobile, our vision of a 5G future keeps the customer front and center, just like the way we built the nation’s fastest LTE network.”
