WOCC: Wireless & Optical Communications Conference 2009
I recently attended: WOCC: Wireless & Optical Communications Conference 2009.
I mostly attended the wireless sessions. What I found new and interesting was cooperative networks and wireless sensor networks.

The need for speed | The Economist
Or, why I still have a job. Thanks iPhone!
Wireless communications | The need for speed | The Economist.
I’ve also pondered the LTE vs. WiMAX. While which technology wins will largely determined by incumbency, I just think the people behind LTE just have the experience and the accompanying better grasp of what it takes to build a massive mobile wireless network. The physical layer hardly matters (see IS-95 vs. GSM).

WiFi Tomato
My old wireless 802.14 router/access point died. In between the Wii, Chumby, and iPhone 3G, a functioning WiFi is nearly a necessity.
But any old access point won’t do; it’s gotta be able support replacement firmware. I settled on Tomato Firmware and the Buffalo WHR-HP-G54. The Tomato Firmware has a slick interface (much nicer than the manufacturer’s) and offers a ssh server, wake-on-lan, and https. It also scans all the nearby networks.
Installation went as described in documentation. For a working configuration, I disabled DHCP service and changed the IP address to one on my subnet. The final troublesome configuration was to set the static DNS server to the default gateway (the default gateway acts like a DNS server, but actually just forwards them, I think). I discovered this issue when attempting to set the time via NTP; the router could not resolve the NTP server address.

On My Reading List
Great scholarly book on telecoms policy, the Internet and innovation – Boing Boing looks like great reading material, and the PDF is free to download.
