AT&T, Verizon and T-Mobile laid out the foundation for their plans of a 5G network earlier this year. The only other remaining carrier left to jump in on the 5G buzz was Sprint. Now it has, revealing plans to launch its 5G network in late 2019.

Sprint is joining forces with Qualcomm and SoftBank to launch its 5G network, but it didn't get into specifics during its announcement. What we do know, however, is that it will be using 2.5GHz airwaves across Band 41 to deliver the new network.

Earlier this year, Sprint partnered up with Qualcomm and Motorola to show off the speeds of Gigabit LTE, and they were getting over 500mbps. Gigabit LTE is the necessary network to lay the foundation for 5G networks.

The 2019 date is quite ambitious. To develop a network takes years and tons of infrastructure expansion. That's the reason all the major carriers are developing a Gigabit LTE network in the meantime to improve their networks while concurrently building the infrastructure for 5G networks.

This puts Sprint in direct competition with other carrier's 5G plans

Last week, T-Mobile unveiled its 5G network plans and it will continue to do so in incremental fashion throughout 2019 with full adoption expected in 2020. AT&T is planning to unveil its 5G network in late 2018. Verizon has already started the process of building its 5G network as well. This will put Sprint's 5G roadmap in the same timeframe as the rest of the major networks despite being so late with its announcement.
