CHL - 5G: The Main Challenge And Its Initial Implications
5G is the upcoming mobile network standard. Its large scale deployment should start in 2019. Succeeding 4G/LTE, 5G promises much higher bandwidth, lower energy usage (per bit transmitted), and the ability to serve many more simultaneous devices.
5G is set to deliver on its promises through a number of changes over 4G:
- The best-known one is the usage of much higher frequencies, including those above 15GHz, around 26-30GHz and 37-40GHz. Higher frequencies allow for higher bandwidth since more wave peaks and valleys are available to represent data (there are other ways to improve bandwidth, like
