<br />Wireless Solutions Examined <br /> <br />The wireless (mobile data) infrastructure is an integral part of the <br />project. No amount of hardware and software data can be useful if it doesn't <br />get to the emergency workers that need it. Many topologies and mediums <br />were considered. These include Cellular Air Cards, UHF Data Radio, Fire-Tide <br />Mesh, Motorola Canopy Mesh, and GE MDS 900 Mercury Network. Staff made <br />site visits at San Marcus, Wiley, Mt. Pleasant, and talked with many other cities <br />regarding their current wireless mobile network infrastructure. <br /> <br />· Cellular Air Cards <br /> <br />· Pros <br /> <br />No upfront cost, 3rd Party Supported <br /> <br />· Cons <br /> <br />Recurring monthly charge, $4500+ <br />· Undependable <br />· Network Security out of our Hands <br /> <br />· UHF Data Radio (400 Mhz) <br /> <br />.
