Clark, what I agreed after reading your very good and informative postings, is that WLL is cheaper to install, more robust and easier to tune.

What I disagree is that it would be "substantially" cheaper. Lets have a look at this:

The infrastructure is virtually the same.

Installation costs are mostly the same (acquiring the BTS sites, building them, fitting the masts, getting the transmission such as microwave links or cable, getting the power source, telling the families living in the building they will not get brain cancer). Savings come from the fact that you don't have to be so much concerned with quality.

The operation is also easier and cheaper, as it is only Mqurice who has fitted the WLL into his car and the handoff problems and resulting dropped calls have not to be monitored and fixed. Its adequate to make sure that certain buildings are covered (plus Mqurice's drive in case his car breaks down just there).

IMO a good analogy is that with WLL you build a Cadillac with a Yugo engine to save costs. Then you try to flog it to the third world to the less fortunate.
