Couple of Satellite Backhaul Presentations


After publishing the emergency communication options last week, I was made aware of couple of recent presentations on Satellite backhaul options. The first one is from Richard Deasington of iDirect at MWC 2015:



The other one is from Vince Onuigbo of Hughes. As can be seen above, the biggest issue with Satellites is the latency which is 600ms for the geostationary satellites. Anyway, here is their presentation:

    Thanks Zahid. Although its very much possible small cell backhaul through satellites, satellite latency budget is much higher than LTE requirements. Secondly, since its only meant for rural areas, I am assuming there would not be X2 interface, if it does exist, I am not sure how the latency will play the role to establish X2. Any field trial result will be very helpful.

    Thanks Rao, agree that Satellite operators need to get the prices down. Its happening, give it a couple more years and they will be very competitive.

    Manoj, agree with the high latency but sometimes there are no options. I am aware of some trials but not sure of the details, will try to find out. With regards to X2, it wont be practical with the satellite backhaul. There are other arrangements where a mesh has been formed between multiple small cells using another backhaul technology like 5GHz WiFi and only one small cell has satellite as the backhaul to connect to the core. Again, not sure of the results and whether any workarounds were done/required.

    In the US the public safety group FirstNet will require satellite backhaul for their remote and emergency deployments for LTE.

In case when fiber and microwave is not available, satellite backhaul comes into play.
