This is a great idea IF you have mountains. Not much chance of setting records in the lowcountry of South Carolina.

Its interesting but, I would be more impressed with such an endeavor if it was being done on 10 GHz!

Makes you kinda wonder what the longest distance record is for a 500mw cellphone doesn't it?

W7PUA and KD7TS did almost 200mi at 10GHz (cw and ssb) over two years ago. (http://pnwvhfs.org)

But getting a 1MB/s path that far is a trick. Good work guys.

This is impressive for unamplified (200mW)distance but it has already been eclipsed by non-hams @ 137.2 miles, on both 2.4 & 5.8GHz, datarate@2.3mbps.

It won't be long before some whacko says all of them violated Part 15 ERP limits. Folks, this is cutting edge technology, available off the shelf, yet some amongst us look down their nose at the accomplishment because it isn't "pure ham radio". Ham radio has failed to keep pace with the wireless world being built around us. RF is RF, radio is radio. Do not underestimate people with the drive to excel but no desire for a ham license!

These are the current 10 GHz standings:

Actually, Part 15 doesn't have ERP limits; it has feild strength limits. See 47 CFR 15.109(a), (b).
I'll let you do the calculations.

The article does not say whether the students, mostly hams, operated under Part 15 or Part 97.

Am I a whacko 'cause I can read a code section?

I still think what they did was mightly cool.

I was at the DEFCON WiFi shootout on the mountain when the record was made. I shot the video. They operated under Part 97, the SSID had the operators callsign.

If you are in the Los Angeles area, we are going to discuss this at our SOCALUG meeting tonight 08/25/05.

Seems to me the better WiFi can be made to work
the less chance BPL has. There is a several square mile WiFi provider in Newport RI targeted on all the boaters who visit during the summer with laptops on board. Because of the propagation over water a good number of land based users are taking advantage of it as well. Now apparently a company is making WiFi
"centers" for installation in high traffic areas like malls prefabbed, not custom built like the Starbucks deal. We have DSL, cable, and now WiFi access locally now and I don't see much room for BPL unless they give it away.

"Now apparently a company is making WiFi "centers" for installation in high traffic areas like malls prefabbed, not custom built like the Starbucks deal. "

Access points come in many flavors, Plug-N-Play. This can even be a "POP in a box" which is a small, integrated WISP server, & access point radio. Access points are appearing everywhere. I spotted several in downtown Arlington VA on lamp posts with diversity antennas pointed downward. I confirmed these were AP's with my laptop while sitting at the lights.

"We have DSL, cable, and now WiFi access locally now and I don't see much room for BPL unless they give it away."

WiFi is only 1/4 of the equation. There is WiMax or 802.16 which is a more robust protocol that would support mobility & roaming. That is already being deployed, in a pre-IEEE standard configuration. Add EV-DO & UMTS highspeed being offered by several nationwide wireless carriers, again offering mobilty & speed. BPL will have limited impact at its' peak since it is not a mobile platform. Everyone is "cutting the cord" including people dropping their landline phones for cellular. As VoIP telephony emerges, a majority will require these delivery platforms to accomodate mobilty, roaming abilty & highspeed. BPL offers none of these...

Anyone wishing to learn more about wireless/wifi/wimax should visit http://www.dailwireless.org for daily updates & in depth news from multiple sources.
