I love Wi-Fi. I used to use it at Starbucks for meetings. Not any more–it costs at Starbucks. I rarely have meetings at Starbucks anymore. I love to go use it where it is free. There are lots of other people doing the same thing. I have talked with them. I see them at free hot-spots regularly. Sometimes the network we’re on crashes and either you go elsewhere or wait until it comes back online. I usually wait. I get something to eat (I need to support the establishment since they are providing me with this service – plus I take up one of their tables for many hours – I need to support them). I do work that I do not need Wi-Fi for while I wait. Once the network is back up, it’s business as usual.
Or is it?
The perspective below by Selina Lo, CEO of Ruckus Wireless, makes some good observations. Take a read and tell me what you think.

Originally developed to allow multiple computers to share access to the Internet, the Wi-Fi lure of “free spectrum, no strings attached,” is driving every imaginable type of handheld device to embed the technology as users demand Wi-Fi access at home, in the workplace and in public venues. Yet as more and more content is poured into Wi-Fi networks, the technology is now struggling to keep pace.
Next generation Wi-Fi technology, 802.11n, is widely viewed as a panacea to the current limitations. A tremendous boost to Wi-Fi, 802.11n increases the capacity of the technology to hundreds of megabits per second (Mbps) from 54 Mbps today. This is achieved by ganging multiple Wi-Fi radios together in a single Wi-Fi device. At challenging locations where the higher data rates are not possible–for example, at the far ranges or in noisy environments–the extra Wi-Fi radios are used to strengthen the signal and extend its reach.
These all sound appealing except for a nagging blind spot–interference caused by neighboring devices that operate in the same unlicensed spectrum.
