panasonic toughbook c-29 with external wlan antenna (2.4ghz and 5ghz) and internal gps.
Bluetooth USB Dongle with antenna

Kismet 2010-01-R1 does support bluetooth scanning/discovery, but what kind of usb bluetooth dongles with a antenna ( or a optional antenna connector) is supported by linux ?

CF-29 toughbook has a internal mini-pci wlan card, and a connector for a external antenna. The external antenna is usually a U.FL connector, that is possible to replace with a more sturdy SMA connector.

there are GPS kits that can be mounted internally:

The panasonic toughbook series are IP55, and possible to get in IP65.

Is wigle maps and openstreet linked?
it should be possible to do that, so open/free wlan acess nodes can be shared between wigle and openstreet.

the internal wlan card in a CF-29 can be upgraded to a card with more output power.

some cards that is usable is:
EnGenius EMP-8602 Plus S 600mW, it has the same connectors as the standard one.

ALFA AWPCI085H High Power 1W 802.11A/B/G mini PCI Card. ( i have read that the alfa cards can be crap )
Antenna connector U.FL connector x2
Power Consumption TX: under 1000 mA
RX: under 450 mA
Output power
IEEE802.11a:
193mW (Average Pow) , 385mw(Peak Pow) at 6Mbps.
IEEE802.11g/b:
522mW(Average Pow), 1574mw(Peak Pow).

the Atheros 5418 AR5BXB72 AR5008 Wifi Mini-PCI 802.11ABGN has 3 connectors, so it needs 3 internal antennas. it is a MIMO card, so think the number of antennas will be a issue.

SparkLAN WMIA-166AGH 802.11a/b/g high power Mini PCI Module (Atheros AR5006XS AR5414) 400mW
Antenna connector: MMCX *1

MikroTik R52 802.11a/b/g High Power MiniPCI
dual antenna connectors

Ubiquiti XTREMERange2 2.4Ghz 600mW 802.11b/g
single MMCX antenna connector

EnGenius EMP-8603 28dB Atheros 11a/b/g mini-PCI
EMP-8603 Premium is mini-PCI types A module, supports dual-band (2.4GHz & 5GHz) high transmit output power up to 400mW in 5GHz and 800mW in 2.4GHz. It has 2x mmcx connectors and 2x jumper wires for external DC 5 volt or 9 ~ 24 V
power supply.

i can legally run 100W maximum output power, since i have a radio-amateur license. No restrictions on the ERP.

I should be able to get some long distance connections with a suitable 20db+ directive antenna.

Here is a calculator that calculates effective radiated power:
http://www.csgnetwork.com/antennaecalc.html

some modes that can possibly be used for long distance wlan is:

moonbounce:
http://en.wikipedia.org/wiki/EME_%28communications%29
meteor scatter

tropospheric scatter:
http://en.wikipedia.org/wiki/Tropospheric_scatter
Atmospheric ducting
http://en.wikipedia.org/wiki/Atmospheric_duct
Tropospheric ducting

high gain antennas and "enough" ERP is needed for this.

Satellite downlinks

some interesting links and facts:
A distance of 304km (189 miles), was achieved using Ubiquiti’s XtremeRange5 High-Power mini-PCI radio and 35dBi 5 GHz parabolic dish antennas.

The link extends from Sardinia to Central Italy achieving data-rates of about 5Mbps. The Italian Center for Radio Activities (C.I.S.A.R), an association founded by a group of Italian radio amateur operators, oversaw the project.

Here is a nice PA, makes about 100- 120W
http://www.sk0ct.se/2g3pa/2g3pa.htm

100W in to a 24db directive antenna is 15316.3 Watts ERP!
That is 15.3 Kilowatts of effective radiated power. :shock:

it should be possible to do that, so open/free wlan acess nodes can be shared between wigle and openstreet.
for various boring reasons the projects are not linked, although we love what OSM does, and have a link to their project from our file post page.

please don't cook yourself while out stumbling :-)

I am not going to stand in front of my antennas while transmitting with that kind of power levels..

0.5W alone can be dangerous if its fed to the correct antenna..
A 36 dbi antenna will result in 1213.7W, if cable loss is left out of the equation.

A wise old saying.

...you are cooking your eyes, nads, etc. so be careful w/a high gain dish esp when sitting right in front of the antenna ;)
