You're right, Rick. It's nothing more than an ongoing progression into smaller and smaller cells, to accommodate more and more users within a given amount of spectrum. They're calling these new and even smaller cells "femtocells," last I've seen. But really, it's just a progression of something that's been happeneing for a long time.

And, for home use, these smaller cells will (or can, at least) use your broadband access as their backhaul network, so in essence, not so different from "WiFi offload."

As I understand it the rapid ramp in use of smartphones and mobile data is putting huge pressure on carrier nets, especially in urban areas. A heterogeneous network (HetNet) of small cells filling in between traditional macro cells in urban areas is now widely seen as the solution. There will be indoor, outdoor and home versions of small cells, and they are still being defined.

It's very complicated to get right. The carriers are trying to leveragre WiFi, too. Many have bought enterprise WiFi gear companies. But its another wrinkle in an already complex job of building out their nets.

I agree @GSMD, I thought WiFi offload was the way to go. Maybe this is for a niche/unique app?

@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

thanks...I thought it sounded too good to be true...need to read more carefully next time

when the market is growing by double digits then its better late than never. And most of the time its company reputation and marketing that wins the customer rather than actual product benefits.

A terrific example of how SoC is beneficial!

krisi, the smoke detector sized unit is just the antenna and amp, not the whole base station.

"base station size of the smoke detector" - amazing what the electronics integration can do...soon some people will be carrying their base stations inside their pockets ;-)

I'd love any analysis of how this compares to Alcalu's Lightradio, SpiderClooud's E-RAN or other approaches.

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
