Demoing improvements to mobile phone networks is difficult. Where an individual vendor such as Intel or AMD can show off an improved CPU architecture mostly by themselves, it takes a lot of cooperation between companies to show off advanced mobile data initiatives.
This is just what Sprint, Qualcomm, and Motorola teamed up to do last week at the Smoothie King Center in New Orleans, Louisiana.
The first part of the story revolves around Sprint’s unique placement in the US mobile network market. While network operators such as Verizon, ATT, and T-Mobile in the US currently operate their LTE networks on low and mid-band LTE frequencies, the vast majority of Sprint's allocated frequency into the high-band range of 2.5GHz. The reason that Sprint has this spectrum is from their short-lived rollout of WiMax technology with Clear.
High-band frequencies can provide several advantages when deploying technologies enabling Gigabit-class LTE and on the road to 5G.
First, the antenna size needed in the 2.5GHz range is substantially smaller than the antenna size for a more common LTE frequency like 1900MHz. This means that when looking to deploy cellular sites utilizing technologies like 4X4 MIMO antenna arrays, Sprint can make smaller cell sites and be more nimble by placing them in areas where they are seeing substantial network load.
