I am looking to order 350 Access-Points and Wireless Bridge but I am confused by the power options. The sites are small (5 802.11b users) so I do not need a switch (3524-PWR). Do I have to buy a Power Injector for both AP and bridge or can I power them via mains (not inline power).
Also can one AP support 5 users, I know it says 3 non-overlapping channels, does this mean that the bandwidth will reduce if all 5 access at the same time. Any assistance would really help.
The 350 Series gear all ships with an included single-port inline power injector. You can just plug this into a wall outlet (ups is preferable).
The bandwidth of APs is going to be around 6 Mbps in an all-Cisco environment; this bandwidth will be shared among all users, if they are all trying to access the AP at the same time.
Cisco says 20-30 users, depending on what they are doing across the wireless link. Latency-sensitive apps, like voice or video, are going to decrease the number of users you can have on each AP.
Do you have any network utilization stats for the site you are trying to connect? Typically, 6 Mbps of bandwidth is plenty for 5 users, as long as they're not pushing huge files around all day.
