I have done this MANY times without cellular and without mesh. Cellular is too expensive and WAY too slow to be really very useful. Mesh is simply not needed for what MOST of them need. > or to use a Mesh network designed for mobility (since 802.11G tends to fall > apart past 30MPH or so). You are thinking that an officer of the law is gonna be using the network while driving at 30MPH+? If their need is to have it working that way, then I would agree that it may be necessary to increase coverage. > Unless this city want's to make a major investment in Mesh...

It's all about explaining benefits and pitfalls. Once the network needs are known (which they are not at this point), THEN a solution is devised. For what it's worth, the second time I did this type of network, we watched a LIVE streaming video from one cop car as it drove all over town without more than a 1 second hiccup (which happened 2 times). Additionally, he was talking to us via an 802.11g wireless voip phone and NEVER lost the call. This was using a mixture of 2.4GHz 802.11b, 802.11g and 900MHz (Mikrotik 802.11a I think), if you're interested. Not too bad for not having purchased, or even considered Moto. I think to dismiss a technology outright before understanding what good engineering can do is pretty short sighted. -- ******************************************************************** * Butch Evans * Professional Network Consultation* * http://www.butchevans.com/ * Network Engineering * * http://www.wispa.org/ * Wired or Wireless Networks * * http://blog.butchevans.com/ * ImageStream, Mikrotik and MORE! * ******************************************************************** -------------------------------------------------------------------------------- WISPA Wants You!
