I live in a life care community - one of 450 people in 300 apartments on 3 floors. When I moved in a year ago, I could get Internet from the house cable, and they provided the modem. I bought wired and wireless 802.11n dual band routers for two apartments, a two bedroom for us and an alcove for my shop. There was plenty of noise from other such routers, but no problem within an apartment. I couldn't use a wireless keyboard, though. The cursor wandered around with the noise. Last month, a company experienced in wiring hotels for wireless put DSL to RJ-45 and 11n wireless access points in each apartment on the second floor, adding 100 transmitters to the mix. DSL with existing phone wiring was far cheaper than running new cable. The intent was to provide universal public Wi-Fi for the children of the residents. They might as well have installed 100 jammers. There were complaints of unusable cordless phones (most in the 2.4 GHz range) and lost Wi-Fi connections that simply reverted to the default IP address range and failed to reconnect. I got a home copy (this is my home) of InSSIDer software and surveyed the halls at 2.4 GHz with a Windows 7 laptop (you need a larger screen to see the signal distribution) I could see 10 to 20 of the new access points, as well as the occasional excursion to -10 dbm (top of scale) as nearby routers and printers kicked in. Great stuff. There are environments where time sync with Wi-Fi hasn't got a chance. Jim Lux was looking for a COTS solution to time sync, and this might work in a controlled environment. Don't even think about consumer radio clocks that sync from unknown Wi-Fi environments.
