		<description><![CDATA[The sharing capabilities Om describes are already available in routers from Gargoyle, Open Mesh and the newer Buffalo models. Unfortunately most of the sharing is designed for WAN to LAN and not wireless LAN to LAN.

The opportunity is not merely in enabling wireless clients to share the Internet, but to access resources on the LAN ... particularly at venues where Internet is unavailable, unnecessary or unreasonably priced. This is where most of the available routers fall down.]]></description>

		<description><![CDATA[The most critical new feature in 802.11ac is Downlink Multi-User MIMO, which allows simultaneous transmission of independent data streams from the AP to multiple clients. A dirty secret of 802.11n is that no matter how sophisticated your AP is (up to 4 antennas), the achievable MIMO data rate is almost always limited by the client devices, such as smartphones, tablets, game consoles, etc., which have one or two antennas at the most.  By aggregating transmissions to multiple clients, 11ac will get back the promise of higher-order MIMO that never panned out in 11n, due to the proliferation of clients with limited antenna counts. Also, by serving multiple clients at once, this will greatly alleviate network contention issues associated with having a large number of users served by a single AP.]]></description>

		<description><![CDATA[Om, this post and the discussion above are some of the best I read on your site lately. I completely subscribe you your view about Wi-Fi, and as you may know Wi-Fi sharing has been the initial vision of WeFi (you actually wrote about us in that context a few times)

Having grown as a company in parallel to companies like FON and Meraki we have followed all the transitions that you described, and WeFi has changed as well along those lines.

The fact is that whether they like it or not, Carriers are desperately seeking to give users the desired wireless Internet experience (just as you described), and knowing that 3G/4G technology have no change to keep up with the demand, they realize now that Wi-Fi provides the missing pieces of the puzzle. So we believe their end-game will be to provide a service, transparent to the user, which gets them connected to the best available bandwidth source around, a lot of which will be Wi-Fi networks which are already deployed &quot;in the wild&quot; (and not only &quot;carrier controlled&quot; hotspots like Wayport, T-Mobile etc.)

So what I foresee is an intertwined ecosystem of Wi-Fi technologies (Meraki-type mesh networks, dual/shared routers like FON&#039;s, manged hotspots as well as a zillion different types of simple low-cost routers) and a smart system controlled by carriers which knows how to navigate and keep the user connected either over 3G/4G or the surrounding Wi-Fi.]]></description>
