I do some consulting and contract IT work for various police departments. Due to various reasons, some of my customers are wanting to utilize the 4.9Ghz public safety band for their wireless needs.
There are a few products out on the market, and the one that I see most often is from Ubiquiti Networks: http://ubnt.com/sr4
. I have also seen a handful of Motorola PCMCIA cards. Both of these solutions fall in the sub $200 range.
These work well and good, but newer laptops and MDC's (Mobile Data Computers) utilize PCIe and expresscards, rendering the before-mentioned options unusable.
The only thing that I have been able to come up with is utilizing a 4.9Ghz Access Point (like a Proxim AP4900) or a mobile router (Like the Oncomm Rocket - http://www.utility.com/solutions/mobile_appliances
). However, these solutions cost north of $1000 per client.
I was hoping some of you experts had experience in this field and would be able to to point me towards a more affordable solution. I am aware that I won't be able to directly source the radios without a license. I just need a direction to steer my customer.
