Hello David, Why is it people associate increase in power as a good thing? If it throws out more then it can hear from the other end, then it's polluting the spectrum, esp with the 200 -> 500 mW devices...
It's possible to do even longer distance links on less power using better antenna... if you're in a country with EIRP restrictions (well UK has 100 mW, or was it 200?, Australia has a max EIRP of 4W, and the US has a max EIRP of 4W on multipoint setups) then less output allows you to do longer links... By using a higher gain antenna you reduce the interference, and increase the signal strength in both directions... using say a 30 mW device in the Europe, you'd normally only be allowed a 5 dBi antenna max (assuming 100 mW is the max)... Maximum system RX/TX = 15 + 5 + 5 + 84 = 109 dBm 3km FSL = 109.54 dBm So less then 3km max... What if you had a -4 dBm radio device, you then might get away with a 24 dBi antenna... Maximum system RX/TX = -4 + 24 + 24 + 84 = 128 dBm 25km FSL = 127.95dBm 25km on 100 mW EIRP... Imagine what distances are likely with 4W, or more... Problem is no one makes devices that do below 0 dBm output... Although once you take cable losses into account this then could drop things a bit as well... -- Best regards, evilbunny mailto:evilbunny@;sydneywireless.com http://www.cacert.org - Free Security Certificates http://www.sydneywireless.com - Telecommunications Freedom Saturday, October 12, 2002, 3:50:20 AM, you wrote: LDC> I just received my first Hawking WB320 and immediately pulled it apart.
