Many of the big carriers are working on building up their 5G networks now. This includes Verizon, AT&T and Sprint. Verizon is working on implementing mmWave, and T-Mobile is working on low- and midband 5G first.
Led by T-Mobile, carriers are starting to embrace the idea of a multi-tier 5G strategy, which includes the use of low-band, midband and mmWave frequencies. T-Mobile has started to launch 5G in half a dozen markets currently.
Verizon is another leader in the 5G market and is currently focusing on the implementation of mmWave 5G. In addition, Verizon created an investment fund named Verizon Ventures. Verizon Ventures aims to invest in areas that would benefit from 5G, such as augmented reality, IoT and artificial intelligence.
Sprint is also offering midband 5G using 2.5 GHz frequencies. AT&T has started investing in 5G but is currently lagging behind the competition a bit. The company has also rolled out 5G Evolution (5GE), which is not actually 5G.
