Hi Crown techs,

If I assembled several racks with I-tech amps and equipped each rack with a wireless ethernet bridge, will I be able to use Iqwic to access all amps assuming all IP addresses are set correctly?

thanks,

Steve

Steve,

Are you referring to Multiple Wireless Access Points or Wireless Bridges? Multiple Access points would require your computer to change IP to access the different networks as well as each WAP would need to use a different frequency. WAPs allow for the connection of multiple users to each other and a wired network.

As Wireless Bridges are fairly new we do not have much experience with them. If you try it let us know how it works.  smile.gif

Without going into too much detail, for those of you who do not know what a Wireless Bridge is, they are devices that allow connecting physically separated networks. Until recently Wireless bridges have been expensive and mainly intended for "Enterprise" use. (No, this is not the Starship  laugh.gif ) Some of these devices use their own proprietary standards that do not work well with 802.11b/g equipment. However some of the more recent Wireless Bridges are compatible with the 802.11b/g standards.

A couple of things to consider when using Wireless Bridges.

*When using Wireless Bridges you may or may not, depending on the model and features, need a Wireless Access Point so that a wireless client (computer) can access the network(s).

*Some Wireless Bridges are designed to share the same channel (Multi-Point Transmission). When you take into account Ethernet overhead and that the Wireless Bridges are sharing the available frequency bandwidth the Total wireless bandwidth can be reduced to as low as 4Mbps with just two Bridges.

*For those Wireless Bridges that may not share channels but are setup to use a different frequency between the different networks (Point to-Point Transmission) you will have a different situation. The 802.11b protocol divides the available spectrum into “overlapping” channels of 22 MHz each. In the States we have 11 channels, numbered 1 through 11. Channels, 1, 6 and 11 don't overlap thus allowing only up to three separate 802.11 systems to operate in the same vicinity of one another. This would allow for only four networks to be wirelessly bridged together that are in close proximity to each other.
