Quick Security Alerts for the Week Ending 3/7/2010

Latest in Optical Wireless

Slashdot shares a new development in optical wireless. The comments on the ISP Review piece are skeptical, hinting that there may be hurdles other than cost to this application competing with radio based wireless. I could not find a link through to any more detail on the research but the remark about dark walls absorbing too much signal has me concerned.

The commenters seem to point out another limitation, that of the need to essentially put optical hardware in each room needing to serve wireless devices. Despite the claims of working around corners, this seems more like an option for new construction to wire a concentrated area rather than doing what WiFi or WiMAX do which is cover small and large areas regardless of construction or infrastructure.

The State of Wireless Mesh Networking

Timothy B. Lee has a good survey of the current field of mesh networking at Ars. The good news is that it seems to be thriving outside of the labs where it originated. Better, the costs of deployment and operation seem especially conducive to use in developing countries. This is consistent with the highest profile mesh networking about which I know much of anything, the OLPC project.

The throughput pales compared to fiber of cable broadband but is directly comparable to what many folks use in developed nations in lieu of running cable throughout their homes, plain old WiFi. I was pleased to note among his examples mesh vendors working on municipal coverage.

There’s also an excellent section on open versus proprietary, noting that much of the systems out there may be open at the lower layers but are largely proprietary. The author definitely throughs his weight behind the need for open standards to aid competition and adoption.
