I have a good one for you to chew on.... I currently have a WAN using PTP T1's to 3 remote offices, about a 75 mile haul on 2, 10 on the 3rd. I run EMHR (electronic medical health records)database, practice management, http, DNS, domain, etc, etc, plus VoIP (Cisco) over this WAN. You guessed it, I am in healthcare... My boss just came to me and said. I want you to be prepared to meet with me next week and discuss Microwave. If we had it, how would we use it? Here is my concern; VoIP- QoS, latency Remote access via internet/VPN, NAT Any of you out there have any experience with this? BTW, I use 2800 series Cisco routers at all locations and am currently using DSL for Internet access.

Thanks. We'll let you know when a new response is added.

The 75 miles would be a problem, but the 10 mile would be ok. I would just watch the voip.

    I would also be leery of rain, fog, large trees, and anything else that can absorb the signal. I've used microwave links of 1 mile and had no problems, and the other poster is probably right about 10 miles. However, unless you've got a REALLY tall set of towers (or buildings to use the roof), I dare say that if you can't clear ground-based objects, even the 10 mile one could be iffy. Bob

    I've deployed microwave for a major cellular company. All of the things you want to do can be done, and have been done, but distance and path quality are the issues (besides cost) that will need to be scrutinized. For a quick, free estimation: go to any of the microwave manufacturer web sites, like Harris Microwave. http://www.harrisstratex.com/ They will have calculation tools. Put in the information from your system and you can get a rough calculation of whether or not the path can even be considered. There is a great deal of difference in capability when it comes to licensed microwave versus unlicenced. The vendor rep can help you, and will provide some free pre-sale analysis. Send me a private message if you'd like to discuss this more.
