The upcoming 5G can be beneficial for IoT in various aspects:

  • higher data-rates
  • low latency
  • better utilization of bandwidth
  • potential wireless power transfer/harvest

Introduction of mm-waves (28 GHz and higher) would be a part of 5G standards. However, mm-waves are tricky and usually require line-of-sight in order to operate.

I wonder, about the IoT devices/applications that would (and could) benefit particularly from the introduction of mm-waves (which differentiates this question with an already cited one and another question of mine that focuses solely on the heavy-load part). How the IoT plans (if it does) to overcome the short-range of mm-wave part of the upcoming 5G? Are there concrete IoT projects that target the usage of mm-waves for its operation?

MIMO and beamforming FTW!!!!!!!

Most carriers aiming on 5G will have very dense antenna networks in order to make the signal available on as many devices as possible.

I think that 5G on IoT will (at least in short term) solely focus on high-bandwith low-range applications while 4G will ensure coverage. In very dense urban areas beamforming (take a look at this) can be used to direct the waves and many antennas can set up a MIMO enviroment where you can get the signal from multiple antennas with LoS and from reflections on surfaces.

As I see things, applications placed away from urban areas will not benefit from 5G at all. On the other side, on urban areas with a good coverage 5G basically solves most IoT problems. As an IoT/embedded systems developer myself, I feel butterflies on my stomach when I think the times of sending only a few bytes a minute will be over for my babies. =)
