ericdabbs Posted April 10, 2012 Share Posted April 10, 2012 Just curious if anyone knew if Sprint is planning to deploy microwave backhaul at 60 GHz or 80 GHz during Network Vision? I know that 60 GHz is unlicensed spectrum while 80 GHz is licensed spectrum so I would think that 80 GHz backhaul would be more costly. It appears that 80 GHz backhaul has a few benefits over 60 GHz backhaul in that it can travel farther and has higher overall throughput capacity. Millimeter-wave (60 GHz) E-Band (80 GHz) Range 3 Km 5 Km Throughput 1 Gbps 10 Gbps Frequency 57-64 GHz 71-84 GHz Licensed No Yes http://www.wimax.com/microwave-backhaul/backhaul-for-wimax-top-8-technical-considerations Quote Link to comment Share on other sites More sharing options...

To me it appears that the contracts for the backhaul put the entire burden on the vendor. They provide a complete package. Ethernet via AAV, Microwave, fiber...whatever. Then NV OEM's take the ethernet connection left for them at every site and connect it all up. How the vendor gets the ethernet to the site is largely up to them. I imagine each backhaul vendor will have their own microwave schemes and you will see tons of variability between vendors. Robert Quote Link to comment Share on other sites More sharing options...
ericdabbs Posted April 11, 2012 Author Share Posted April 11, 2012 Can those specific microwaves used for LTE? This article stated those microwaves used to support WiMax network I am pretty sure that 60 GHz and 80 GHz microwave backhaul is applicable to both WiMax and LTE. Those 2 frequency ranges are common for microwave backhaul. 1 Quote Link to comment Share on other sites More sharing options...

NiteSnow Posted April 11, 2012 Share Posted April 11, 2012 Microwave links are just wireless bridges. They can be used with any technology that requires IP connectivity. Quote Link to comment Share on other sites More sharing options...
digiblur Posted April 11, 2012 Share Posted April 11, 2012 And one frequency doesn't provide more bandwidth than the other. It all depends on the modulation scheme and channel width they can use. As you go higher in the spectrum you also have to worry about more rainfade. 1 Quote Link to comment Share on other sites More sharing options...

irev210 Posted April 11, 2012 Share Posted April 11, 2012 (edited) I have recently seen some of the Backhaul contract awards.

I imagine each backhaul vendor will have their own microwave schemes and you will see tons of variability between vendors. Robert The backhaul component is very interesting. Do you have any other examples, like you provided with the Chicago rollout (like boston ) I've always been curious how the backhaul vendor effects the end-user's experience and how local backhaul actually ties into the sprint network. I would love to hear any insight on how they choose backhaul, the performance difference between vendors (say AT&T vs. Level 3, Comcast, etc). Lastly, how often does sprint actually have their own fiber reach a base station? Edited April 11, 2012 by irev210 Quote Link to comment Share on other sites More sharing options...
xcharles718 Posted April 11, 2012 Share Posted April 11, 2012 I wonder why doesn't microwave their own fiber when they can? They do have fiber in a few U.S. cities but not the metro loops needed to bring them to the tower. So I wonder if they ever considered microwaving it from their IP Node to the tower. 2 Quote Link to comment Share on other sites More sharing options...
Deval Posted April 13, 2012 Share Posted April 13, 2012 (edited) Lastly, how often does sprint actually have their own fiber reach a base station? I'm assuming where ever Sprint can provide local loop access, they can do that. Edited April 13, 2012 by Deval Quote Link to comment Share on other sites More sharing options...

I am also curious if a base station hooked directly into sprint's network performs better than one that is not. Quote Link to comment Share on other sites More sharing options...

Or maybe it's this, can't really tell the difference. 1 Quote Link to comment Share on other sites More sharing options...
