Metro Wi-Fi Imbroglio?
With Google soon to open their massive Mountain View Wi-Fi "experiment," metro Wi-Fi networks will only become more important not less. In fact they already have in places like Anaheim (CA), Philadelphia (PA), Tempe and Tuscon (AZ), Corpus Christi (TX), Henderson (NV), New Orleans (LA), Daytona Beach (FLA), etc.
The big question is will users be able to actually get on these networks from inside their homes and offices and use them for anything other than getting to myspace.com? And there remains a fair amount of skepticism about how these metro Wi-Fi networks will perform with lots of users on them....IF users can get on them.
There's recently been a ruckus about how hard it is for subscribers to reliably connect to these metro Wi-Fi networks despite the density of the node deployment. This AP story made the rounds across the country about how hard (and frustrating) it can be for people to connect.
Meanwhile Google's network in Mountain View (population 71,000+) is expected to go live (read FREE) over the next couple months and now has more than 400 nodes dispersed throughout the 12 square mile city. Google has recognized that the success with which people can connect to this network is extremely important. That's why they're fairly religious about having people use "purpose-built" metro devices in their homes to connect to the network.
The problem is that most people will expect to use a Wi-Fi-enabled laptop to connect to these metro networks. That's great if you're close to a Wi-Fi node and sitting in your front yard. But most will want to be inside their home, behind walls and encumbered by trees. The Wi-Fi cards in laptops are typically low power and make lousy roaming and association decisions. Generally speaking, several times each minute the laptop will do a background scan to see if there are better access points with which to connect.
This constant probing is useful for users walking around in a building where there are lots of APs from which to choose but can be detrimental for metro environments. This adds a tremendous amount of overhead to these outdoor networks which need to conserve as much airtime as possible. And if and when they do connect to a metro node, they don't do it based on any real intelligence.
Using multiple antennas and software that determines the best metro node to use (based on things like fast probe responses, signal strength, etc.) would provide a much higher resolution picture of the Wi-Fi environment. Add to this, more power and the ability to automatically alter the TX/RX path and you have a much better chance of connecting (and staying connected) to the best metro node even if stuff changes (and stuff changes).
Ultimately people will want to cut the broadband cord to the home if they can, just like they're doing with their cell phones. Though a "B" reality show at this point, these kinds of innovations and technical advancements are making metro Wi-Fi more real than ever.
This is an odd story of one of our employees (and boy do we have some odd employees). 

The IPTV hype is happening in a big way, just not in the U.S.
In France, IPTV is even sold in consumer electronic stores like
