JThorson Posted January 5, 2015 Share Posted January 5, 2015 With T-Mobile and now Verizon making a big push for LTE LAA (license assisted access), I thought I'd start a thread for general discussion of it.For those who are unaware, LTE LAA is the planned use of 5GHz spectrum to supplement downlink with licensed spectrum. Since there is a lot of unused 5GHz spectrum (500MHz+), it allows for many 20MHz wide carriers to aggregate with licensed downlink. This will never be done on a macro cell, and is designed for small cell deployment in dense areas where the capacity is needed.What do you guys think about it? If T-Mobile deploys it as well and as fast as they say they will (they intend to start seeding devices this year), I don't think Sprint could be the speed king even with 2.5GHz small cell deployment. That makes me wonder if Sprint is going to utilize LAA in the future. Merged two threads on same topic -- Tim They are planning on using the 5Ghz that is used with Wifi. I don't know about that. It is an interesting idea. http://www.cnet.com/news/ericsson-aims-to-triple-network-speeds-for-4g-phones/ Quote Link to comment Share on other sites More sharing options...
stuckinohio1 Posted January 5, 2015 Share Posted January 5, 2015 old news is old? It was discussed in the T-Mo thread that T-Mo was looking to use some Unlicensed 5GHz on its network. Quote Link to comment Share on other sites More sharing options...

caspar347 Posted January 5, 2015 Share Posted January 5, 2015 This is pretty cool, but I'm not totally sure where I stand on carriers, especially the big 4, using unlicensed spectrum. Technically it is allowed, but what happens if hypothetically all 4 are using multiple channels of 5Ghz in the same area? Would interference between carriers and consumer/business routers be an issue? I know 5Ghz unlicensed is a huge band, but like 900 and now 2.4 it will eventually become saturated. Anyone else? Am I crazy for thinking this? 4 Quote Link to comment Share on other sites More sharing options...
JThorson Posted January 6, 2015 Author Share Posted January 6, 2015 I was thinking the same thing about interference. It will be interesting to see how this plays out. 1 Quote Link to comment Share on other sites More sharing options...

Am I crazy for thinking this? Ericsson RBS6402 picocell solution will be able to consistently sweep the unlicensed spectrum within it's individual RF environment, and adjust the connectivity (attach) to a vacant 5GHz on the fly. This way each SmallCell radio within any given indoor environment could be attached to a completely different WiFi channel, while the IMS core takes care of the rest. Obviously at some point all freq bands will get saturated, but right now 5GHz is still fairly vacant. 1 Quote Link to comment Share on other sites More sharing options...

Fraydog Posted January 31, 2015 Share Posted January 31, 2015 http://blogs.cisco.com/sp/cisco-wifi-wi-fi-service-provider-lte-u-by-any-other-name-is-licensed-assisted This is a good, balanced account of the pros and cons of LTE-LAA. I support using this spectrum but I would hope the politeness work done in Europe would apply here. Quote Link to comment Share on other sites More sharing options...

Paynefanbro Posted February 12, 2015 Share Posted February 12, 2015 Sprint is already at an advantage by having higher propagation spectrum than 5GHz. They also have tons of it. And when Sprint feels necessary, they can also dive into the LTE-LAA game and go even further. So no, I don't think Sprint has lost its advantage at all. 1 Quote Link to comment Share on other sites More sharing options...

So no, I don't think Sprint has lost its advantage at all.Plus 2.5 will be deployed on macro cell giving sprint the coverage advantage. I imagine it'll be hard for mutiple carriers to all find enough physical room to place small cells in congested locations. Quote Link to comment Share on other sites More sharing options...
Destroyallcubes Posted February 12, 2015 Share Posted February 12, 2015 That would give house sized coverage zones with that spectrum if it is anything like Wifi. If Verizon and Tmobile start this, what keeps a troll from using the same spectrum just to cause issues? it honestly is sort of a last ditch effert for them to try and maintain their "speed king" title Quote Link to comment Share on other sites More sharing options...

With WiFi you have to rely on 5GHz for uplink, but with this solution the licensed spectrum is used for uplink. 3 Quote Link to comment Share on other sites More sharing options...
