1400 signal strength

Unanswered Question

I am just wanting to check and see if I have good signal strength, hard to find documentation.


I am using 802.11a with the 1400 outdoor bridges. Signal strength is -35. I am used to 802.11g where it is usually -45 to -65 that is considered good, what does it mean that I am lower?

-35 is relatively a good signal strength when compared to -45 to -65. Negative numbers should be looked in a reverse order.

Agree, -35 is stronger than -45, as in 35 below zero is warmer than 45 below. :)

I would also think that you would be connecting at 54mb with no problem. Do a

"show dot11 associations all" command in priviledge mode to get more details about your connection. It should show you how fast you're connected.

These signal strengths are dBm values. The dBm is the logarithmic ratio of received signal strength to 1 mW. -35dBm is about 0.3microwatts, -45dBm is 0.03 microwatts and -65 is 0.0003 microwatts. So the -35 received signal is actually 10 times stronger than the -45 signal, and 1,000 times stronger than the -65 signal. Thats a strong signal!
