Will it not be simp,er to use wifi inside the building, maybe bridge the baseband protocols and wifi. Since there is a spectrum scarcity, I think it makes sense to stick to a single radio link, wifi and have multiple back ends. Maybe the radio and handover portions of wifi can be decoupled from the upper layers.
In fact it would be a radical telco model, if they were decoupled like wifi providers. the radio network can be a different operator and the back haul a different operator. Works for cable, long distance and wifi. Why not for cellular ? will save enormous spectrum.
@GSMD: Wi-Fi is a part of the Ericsson strategy, and part of pretty much everyone's small cell strategy although details are fuzzy to me. Here's what ABI analyst Nick Marshall said in a bullet point about Radio Dot:
· Integrates with Ericsson WiFi and can do real-time traffic steering Wi-Fi/3GPP
I get the feeling telcos discourage the wifi offload. They probably feel, retaining services in the cellular bands lets them control their customers. Most of us are in wifi hotspots during office hours or at home except when travelling. We may find we need cellular access only for backup access.
Not a likely scenario but telcos are not known for great foresight or radical changes in business models. Or innovation. I have two telco CEOs in my circle of friends, I should know !
