Hey guys - was wondering if anyone out here has any good material on the access points. The manuals on the samsung website just do not go into detail about everything that the ap's can do. I have a customer with 4 ap's installed for voice and data and the voice breaks up real bad. They are not even using the data at this point. Thanks in advance. I also posted this in the Installers forum but no response so I thought I would try here as well.

If there are other wireless in area, try changing
to "B" instead of "G", this worked for me

I didnt see any other wireless devices in the area. But I will give it a shot. thanks jb

From what I have learned you have to attend the instructor led wireless course in Texas to get the documentation on the access points. There are a lot of things that would affect the handofs between access points including whether or not a wireless study was done before the installation.

When you say you don't see any other wireless devices, did you do any spectrum analysis? Even if you used something like Net Stumbler, you might be missing other devices. Remember that even microwave ovens cover the same spectrum, so don't place AP's close to a break room.

How close are the AP's? Did you do the recommended "planning survey" to determine their locations?

Also, as someone mentioned... you get better output from the AP's if they are set on 802.11b instead of 802.11g. The phones don't need the extra bandwidth and you get a stronger signal.

First: Did you install your access points in a non-overlapping channel layout? In North America only channels 1,6 & 11 do not overlap frequency spectrum of each other, so you should make certain that you never position access points of the same channel within range of each other. The layout of channels accross your coverage area should look like this:

...ch 1...........ch 11.............ch 1...
..............................................
..........ch 6...............ch 6............
..............................................
...ch 11...........ch 1.............ch 11..


Second: Have you measured the "Signal Level" and "Call Quality" with the SMT-W5100's (or WIP-5000) by using the "Display RSSI" feature in the Hidden Menu? This can be a great tool to find areas that have poor signal or access points that are interfering with each other. If you do not know how to do this you can send me a Private Message and I can respond.

Third: As already stated in previous post; anything that operates in a 2400Mhz freq. in the coverage area can and will interfer with the quality of reception on the Wireless IP Phones. So these items should be removed from the operational coverage area. This includes: Any Bluetooth device, Microwaves, Cordless Phones, Wireless Video transmiters and other Wireless Access Points/Routers.

Hope that helps,

Thanks for all of the replies guys - great info.

First - My supervisor conducted a "planning and design" according to the manual. He conducted this in a wide open warehouse (before all of the metal shelving and racks arrived)

Second - When we became delears I received all of the certs listed on their website(did not know that the wireless was instructor led - until I called tech support and they would not offer any support - this was of course after the sales team sold a few of them)

Third - I did set the WAP's up in channels 1---->6------>11------>1------->6 so that neither wap would overlap with one on the same channel.

I did not know about net stumbler so thanks alot for the info. We became dealers about 6 months ago and this product line is the first that I have dealt with WAP's. These babies are much much more than your standard linksys waps. I am still trying to get my company to send me to school for the wireless course but they are reluctant. Of course this is a customer that is 2 1/2 hrs away (Isn't that the way it usually goes - lol). thanks for all of the help guys - you truly make this a great site for all of us tech's out there!
