IPTV over wireless? Why not?
Ruckus' Selina Lo talks home improvement and Wi-Fi futures
SaaS data loss: The problem you didn’t know you had
Interview You want cheap Wi-Fi? "You'll get what you pay for," warns Selina Lo. "Wi-Fi makers are in denial. The system doesn't work properly, and will get worse."
Thank God, she says happily, "for manufacturers like us!"
No, overweening modesty isn't her major personality flaw. And as CEO of Ruckus Wireless, her third start-up company (previous success was Alteon), it's not obvious why she should suffer from it. Anyway, I agree with her:
Ruckus president and CEO, Selina Lo.
"Wi-Fi is a selfish technology. What people need is the ability to make Wi-Fi behave. That's what we do - we make Wifi into a utility."
For anybody who lives in a congested wireless neighbourhood, the "will get worse" prediction is already coming true. You go to the computer store, you buy your Wi-Fi access point, and then you find that you aren't the first; and you also find that it's slow. Promises of "faster than wired Ethernet" are made - promises which don't translate well into reality.
If you think your Wi-Fi is the exception, Selina Lo has an acid test for you; try running IPTV across your wireless link. With a Ruckus wireless link, you can.
This, says Lo, explains why all the "triple play" service providers are queueing up to buy Ruckus technology. It's a technology with the snappy name of MediaFlex: "The first in-home multimedia 802.11a/b/g system developed specifically for service providers" says the blurb.
Sitting listening to Lo explain all this, I had to admit that she doesn't present the typical image of a CEO of a high-tech start-up. She is (you should excuse my directness) tiny and cute. If you're looking around the hotel lounge for her, and spot her, you might easily notice her, and pass her by as being far too young anyway, and lacking in the sort of charisma which the typical American VP tries to cultivate.
Listen to her talk, however, and the charisma hits you between the eyes.

Don't you just
Hate it when those socialists are right for a change? I mean it's not like you can't get a wifi mesh set up the problem is security on such networks.
Although saying that, I'm starting to believe WiFi is a bad idea and we should have never eft the oceans.
Radio systems engineering
The traditional approach to radio systems engineering attempts to maximize the use of the radio spectrum, because it is a finite, limited resource that has to be shared effectively by all users.
As the density of WiFi networks increases in an area, they increasingly interfere with one another. Eventually they will all become useless.
The solution to piping television around your house is to use wires - either traditional co-ax carrying base-band analogue or RF signals, or twisted-pair carrying IP network packets. Neither of these will deteriorate because of your neighbors competing for use of the same radio spectrum.
Well, sounds good, but...
I regularly (nightly) stream recorded TV (MPEG4) over WIFI through three floors of a Central London terraced house, without any issues.
Maybe I'm just lucky :)
