To the best of my knowledge Terabeam is the "ONLY" true point-multipoint solution. The Multilink system from GoC that you referred to is a pt-pt solution, they are using multiple transmitters and receivers on each link for redundancy etc. The other system that is advertising a solution suggesting some form of multi-point environment is Airfiber, the reality there however is that they have designed a meshed network of point-point links via ATM.

As for point-point being old hat, it is in a base form, however significant strides are being made with regards to reliability of the links etc. as well as the deployment of eye-safe systems. Ourselves (fSONA) and Terabeam are running at 1550nm which allows for much higher laser power use compared to other wavelengths, but getting that laser power at 1550, cost effectively, is no slam dunk. For that reason I would suggest that the optical wireless sector is really just starting to look at coming out of it's infancy and into the mainstream.

There is an advantage to the pt-pt concept as well, that is flexibility. From a network capability perspective a meshed or switched pt-pt network compares quite nicely with the point to multipoint networks. The drawbacks for a large point-point network is the number of transmitters required, the benefit is the cost where only a couple of links are required and the flexibility of how and where you deploy.

I hope this has been of some help.

Sincerely,
