WiFi: Born Again (Modern Day Phoenix)
Many may not agree with this post, some may will, but what I feel LTE and enormously increasing demand of data with always on applications has given us the modern example of PHOENIX. WiFi in recent times has emerged strongly as a big time competitor to cellular world, Although it started and still believed to be an offloading option for cellular with free spectrum and cost margins. May be it would be too strong statement to underestimate WiFi, but wouldn't the case be different if WiFi was not deployed as a Offloading option? The serious deployment around the globe WiFi as unlicensed offloading with 3GPP could be one of the reasons operators, engineers and the world has started looking WiFi as option for cellular killer, don't know would that be ever possible. Taking no credit away from WiFi world, they have come up with seriously good solutions with 802.11n/ac.
If I try to look ahead, 3GPP coming up with LTE-U/LAA trying to "provide the solution to a old solution which itself has become problem now, in short to halt the increasing popularity and gaining importance of WiFi as primary technology. Yes it is too early to predict but the pressure is mounting.
That is why I believe the WiFi has born again and this time it is much stronger and has much stronger portfolio and the re-birth has alot to do with using WiFi as a offloading technique.

9 年Of course using unlicenced spectrum is quite cost effective and this definately means that wifi will catch considerable portion of cellular traffic. However, the relatively low carrier flexibility will increase interference in dense wifi deployment scenarios which will eventually saturate unlicenced band and this will drive the need towards more advanced technologies and/or additional spectrum deployment.

9 年i use 4G-LTE if i'm in a car, bus, train, remote-rural-village_without_optical-fiber; in-Flight & in-Ship i use ?? Satellite-GSM https://goo.gl/ysxXH6 ??; at home & office i use optical-fiber-internet+WiFi; i pay 99% internet bill for fiber+WiFi & 1% for LTE; i watch Youtube only on WiFi+optical-fiber-traffic..
