nice
About LWA, it is not true that "LWA requires a considerable CAPEX because existing operators' Wi-Fi APs have to be replaced with LWA-aware APs and the existing Wi-Fi APs everywhere (operator-deployed Wi-Fi and user-deployed Wi-Fi) will not be used. ". China Telecom just showed a LWA demo using an off-the-shelf WLAN AP with quite good performance. You could find the information here (in Chinese). http://www.c114.net/news/117/a920814.html
Theoretically, it IS possible for a Wi-Fi AP to implement LWA through software upgrade. However, existing Wi-Fi APs installed across the operators’ networks are, in general, low-priced (and thus not high-performance) APs specifically designed for massive, nationwide deployment. Given that, it is NOT impossible, but practically hard for these Wi-Fi APs to implement LWA due to their poor CPU capability.
Of course, we agree that supporting LWA through software upgrade IS possible when high-performance APs are used instead.
Interesting reading developed by Netvision Telecom about LTE/Wi-Fi Multi-path aggregation is the most cost-efficient LTE/Wi-Fi integration solution as it allows an operator to expand network capacity by using existing Wi-Fi networks (operator-deployed Wi-Fi and user-deployed Wi-Fi) and will support 300Mbps on LTE and 866Mbps on Wi-Fi, theoretically maximum download speeds can be 1.17Gbps.
It is a must read as everywhere this is getting discussed... how to introduce WiFi as another telecom technology. Nice information.
This is LWA LTE and WiFi link aggregation option under finalization at 3GPP level (R13), that can be considered as an alternative to LAA based on LTE Advanced Carrier Aggregation using unlicensed spectrum.
Yes, LWA is uder standardisation process, but at radio access level point of view, whilst the Netvision solution is a parallel approach based on trasport layer, hence not involving 3GPP process, with related Pros and Cons...
Thanks for sharing yet another piece of great information. The MP-GW which apart from UE (app) support seems to be the heart of the solution, do we have any lab trials or demo going on with this or this is much earlier stage as of now?
@Rahul, this solution has been commercialized in KT - http://bit.ly/1ZCq2Iy
