T-Mobile the underdog changing things

I want to explain some of the few details behind what makes a carrier a carrier and how the perception of connection changes based on different factors. These factors often depend on resources that are limited and largely owned by the bigger corporations. To start, I will need to give brief overview on how you connect to a carrier like AT&T or T-Mobile. They each own certain amount of airwaves known as spectrum, much like a TV station or radio broadcast. Each carrier can only then broadcast over spectrum that each of them own. And spectrum for cellular carriers is a very limited resource. The original spectrum to go up for sale was bought up by many different regional carriers. Most of these carriers have now been swallowed up by either AT&T or Verizon, who own the majority of the available low band spectrum. What is low band spectrum versus the high band? Well, low band spectrum can reach much further distances, and penetrate walls much better than high band, but hig...

AWS was the clear best choice for deployment which currently housed their HSPA+ network. After this rollout was complete it would get LTE onto all the current AWS towers along with the current HSPA+.  By the end of 2013 T-Mobile had a decent LTE footprin...
