Two weeks ago I purchased and started using a Fitbit Flex. It is basically a set of accelerometers, some computing, and a Bluetooth wireless connection bundled into something you can wear on your wrist. This little gadget won’t turn me into an athlete, but I’m hoping it might make me a little more aware of my astounding lack of activity. And in the process, possibly shame me into moving a bit.
A lot of folks these days have at least part of their home network on wireless ethernet, or WiFi. I have two wireless access points in my house, for example, and plan on adding a third. Wireless networking has security considerations: unless your WiFi network is encrypted, someone outside your home can use your bandwidth or, potentially worse, intercept your data. Wireless security was improved significantly a few years ago with the introduction of WPA (WiFi Protected Access) after the previous security method, WEP (Wireless Encryption Protocol) was “cracked”. Since then, wireless networking has been pretty much secure against any intrusion. Until now…
I would love to have a no-compromise wireless network in my home. In this imaginary scenario, I would be able to put a computer anywhere in the house, even carry one out onto the patio, and get something approaching gigabit Ethernet speeds. Heck, I’d even be happy with half that: 300 Mbps… or even a really reliable true 100 Mbps link- that would be nice.
Unfortunately, after about a decade of living with wireless, I can say that surprisingly little actual progress has been made. Using wireless still means giving up network performance…
