But it changes how much signal is needed to be useful.

Sensitivity does not change the power level of the received signal. -- Josh Reynolds CIO, SPITwSPOTS www.spitwspots.com On 02/22/2015 08:42 PM, Patrick Leary wrote: ...also, seriously. You any like it's even possible to compute a link budget without accounting for sensitivity, MIMO scheme etc. Thinking dBm and dBi are the only numbers in the equation has me wondering how experienced you are Adam. You do realize don't you it's impossible to understand link budget without knowing a whole host of things besides the output power and antenna gain?

And I wonder if he was comparing the naked 10dbi SM to a 15dbi wimax CPE. You could definitely get 10db more by turning up the tx power all the way and using a bigger antenna, and maybe you can do some electronic magic to make a little more out of the signal you're getting, but there's no magic that makes more db's appear. If both systems started with the legal +40dbm then how does one end up with 10db more at the CPE? I'm a skeptic by nature. <blockquote> Testing back to back between Cambium and Telrad products on the same tower at the same azimuth, we found an average of 10dB better RF levels with Telrad’s equipment." </blockquote> </blockquote>
