Comments on: Citywide Wi-Fi equipment maker boosts speeds

Tropos Networks announces an upgrade to its product that will boost capacity 50 percent.

Expect great stuff from TROPOS

the self forming, self healing network is here. Expect the synergy with 802.11n consumer gear, and services such as VONAGE, to push copper into the recycling bins.

*laff* if the price of copper gets much higher, the scrap copper value will pay for the Fiber Being Laid.

Bandwitdh statement is flat-out wrong

The article claims: "Because the 5GHz spectrum works at a higher frequency, it offers more bandwidth...."

This statement is simply not true. What determines the bandwidth is how much spectrum is allocated. There are twleve 20 megahertz channels allocated for 802.11a in the range of 5.0 gigahertz and above.

The data rate achieved, up to 54 megabits / second, is a function of the amount of spectrum allocated and the chosen communications protocol.

802.11a is less congested and therefore a good choice for building a mesh network. It is not faster because it's at 5 gigahertz.
