RE: Cisco Aironet 340
Dennis, I've worked with the Aironet 340 wireless bridge, and my experience hasn't been a joyous one. The wireless bridge is usually used to connect buildings using an 11mbps spread spectrum radio connection. For around four months, the airbridge worked nearly flawlessly except for some excessive broadcast traffic. (my fault - didn't bother to segment into broadcast domains)Around a month ago, we started to experience tremendous amounts of interference, which would bring the airbridge down for hours at a time. For two weeks I moved the antenna, modified the configuration on the airbridge to a lower speed, and ultimately called Cisco to try to solve, what appeared to be a complete enigma. Turns out it wasn't a hardware issue or a configuration issue. A voicestream cellular tower on one of our buildings was causing the interference. Our airbridge was apparently interfering with their cell tower, and as a result, their high power testing of the tower caused interference on our airbridge. While you're using the roaming aironet 340, I thought you could still use the info. BTW, we use a 3com wireless inside our buildings for laptops and it works pretty well.

RE: Cisco Aironet 340
Dennis, That is basically what it is...wireless networking. The Aeronet card will slide into the PCMCIA slot on your laptop. You will also have to have wireless hub(s) installed. At least one for each floor where you want to implement the wireless cards. We use two per floor here where I work so that all users can obtain a good reception from pretty much anywhere on the floor. You will also probably want to employ the wireless encryption (WEP) so that someone cannot pick up your network from outside your building or your elevator lobby area. ;-) We use Lucent technology here so I am not as familiar with the Cisco product line but I believe most (if not all) of the wireless use the same standard.

Re: Cisco Aironet 340
Do you have the omni-directional antenna, or directional? The directional is polarized and shouldn't interfere or be interfered with other RF sources. The first time I used directionals, they wouldn't get a strong signal, that is until we had both in the same orientation. I had them 90 degrees out of phase, anyway they work rather well.

RE: Cisco Aironet 340
Rodgers, We use the omni-directional yagi antenna. Perhaps the directional antenna may help. The configuration worked pretty well until around a month ago when the interference began. Prior to that signal strength and quality were high. I don't believe normal cellular transmissions interfere with the bridge however, it appears that interference occurs only during testing periods of the cellular tower. This is largely my guess since I am not up for a spread spectrum analysis of something I couldn't correct. Voicestream itself wasn't responsive to queries regarding their cell tests, but the FCC informed us that indeed the cell carrier is capable of interfering with the bridge since our frequency is unlicensed.
