>The Cincinnati FM Club is delighted to invite anyone and everyone 
>interested in digital communications to a presentation by  Brandon 
>Schamer, KG4NVK, who will describe long-distance (55 mile) communication 
>on the 2.4 GHz ham band using 802.11b protocol, and a host of computer 
>aids, along with novel antennas and lots of ham ingenuity.
>
>The meeting will be held at 7:30 p.m., Wednesday, February 2, 2005 at

>Any and all amateur radio operators and interested parties are cordially

>Brief Synopsis of the meeting follows:
>
>================================
>
>Long Distance (Multi-Mile) 2.4GHz 802.11b Communications
>Featured Speaker: Brandon Schamer, KG4NVK
>
>We will be treated to a discussion about how a group of four local hams 
>won the  2004 "Wifi Shootout" in in Law Vegas, Nevada,  at the DefCon 
>conference, which bills itself as the largest underground hacking event in 
>the world.  This is a competition to see who can make a Wi-Fi connection 
>reach the farthest.  Brandon will describe how the group made a 1MBPS 
>connection over a distance of 55 miles, first using an amplifier and ham 
>radio protocol, and then turning off the amplifier and using the "bare" 
>32mW per station.  This was done using inexpensive (<$100) off the shelf 
>hardware and a bit of ingenuity. He will also discuss practical matters 
>relating to ham operation using WiFi equipment.
>
>The group consisted of Andy Meng, N8MX, Brandon Schamer, KG4NVK, Justin 
>Rigling, KC8OIO, and Ben Corrado, KC8RKO.  Each is studying engineering at 
>schools dispersed throughout the country.  Brandon is currently enrolled 
>at the University of Cincinnati, studying Electrical Engineering.  They 
>plan to get together again next summer and attempt to set an even longer 
>record. The main problem they had this year was that the road ran out long 
>before the signal strength dropped.
>
>Brief Bio:
>Brandon's first experience of electronics was finding friends with similar 
>highly creative personalities in high school theatre group. They led him 
>to the amateur radio club at Xavier High School and the variety of their 
>activities and pure mayhem of extreme ideas kept him hooked. He loves to 
>help with the building of all of the millions of their crazy ideas, as 
>well as the WiFi competition, and he will join them again this year.
