There is no evidence that microwaves cause anything but heat dissipation 
damage. A microwave oven operates on about 2 GHz and a fair bit of energy must 
leak out of some of these as they have an ERP (Effective Radiated Power) of 
about 1 KW or so. Mobiles operate on 0.9, 1.8 and 3 GHz (I think)
Microwaves are officially from 1 GHz up (UHF below this)
I cant imagine a LAN link having an output power of more than 100mW or so. A 
high gain dish would focus this by 10 dB or so which would give an ERP of 1W, 
hardly enough to do much harm
