Sounds interesting...if interesting is the correct word to use...

The School in question is a public school, is this any different?

I will be passing this onto the boss tomorrow.....

Thanks,

B.

Brian,

Since it looks like you're doing this for a public body, you should
be aware that you need to keep within 100mW (20dBm) EIRP (effective
isotropic radiant power).

To reach 2km with a good signal level, you are very likely going to
break the UK maximum permited RF power levels unless you buy some
very fancy high gain aerials.

See:

http://www.cisco.com/warp/public/102/wlan/faq-hardware-us-calc.xls

For a good design reference.  (Don't forget to set the regulatory
domain to ETSI)

Other manufacturers may have slightly more sensitive radio kit than
Cisco to improve the range but I doubt if they'll be significantly
different.

Sorry to be a spoil sport.

Regards,

James
