A regular wireless G setup will pick up the signal in a trailer. Upgrading to wireless N will only be of benifit if your wireless is extremely onld because the distance is dependant on the transmitter.  I've used a pc with external antenae and a few laptops with std. wireless G and they all work fine. If you have a windows based mobile device, the software will run on it too.

One trick you'll need is to refresh your layout (explained in the instructions) every once in a while if the broadcast stalls in between groups going out on the track.

Otherwise it works great and is nice to be able to relay times to your driver  (during practice)

Do we have any knowledge as to whether or not the evening's Delnet race results will be posted online as they were last year, or was that something different?
