Dr. Zaghloul, very interesting achievements. Where copper is impractical or too expensive, you've demonstrated that wireless fits the bill.

I'm guessing that the 45-24 ethernet bridge is characterized by 4.5 Mbps bandwidth at 2.4 GHz. What is the line-of-sight range of your technology? I'm also interested to know what the physical limit is before there is excessive saturation of the airwaves such that units begin to jam each other. I am by no means an RF or communications engineer (I am an investment analyst by trade), but a more technical colleague described to me a shortcoming of wireless communications whereby modems will begin to jam/collide when multiple units are used, saturating or "using up" the common airspace.

I'm just envisioning what will happen if multiple providers and multiple clients want to use wireless technology sharing the same range of carrier frequencies. Surely there is a limitation at some point??

Also, is it possible to achieve bandwidth binding, effectively getting greater bandwidth by using multiple ethernet bridges? For example, using a pair of your 45-24 units at each end of the wireless bridge to achieve 9 Mbps (close to 10Mbps 10Base-T speeds)? Or, say, 22 units on each end to achieve near 100 Mbps?

Congratulations on the recently increased profile and visibility to the world.

Randall
