My company was recently acquired by a third party which is now in the process of reviewing our infrastructure.
One of the things they are covering is our existing MAN, so I'd like to get some unbiased input regarding MAN technologies.
Sites A and B are half a mile apart.
Site C is about 10 miles from both A and B.
Site D is about 20 (?) miles from site C and 15 miles from sites A and B.
At an absolute minimum, sites A, B, and D all need to connect to site C. I'd like to keep them all in a mesh like we do now.
We're currently using a 100 megabit fiber optic product from ATT, and it's working fine. During a normal day, the lines hover around 5 - 10 megabits utilization, but when the backups run (or I reimage a system over the network) we can easily hit 80 megabits per second.
We're using VoIP at all of these locations.
Our auditors are suggesting that we use some kind of point to point wireless technology between these sites instead of the fiber optic lines we're currently using.
What are the pros and cons between these technologies?
