2 W IRELESS C OMMUNICATION F IBER N ETWORK

3 W IRELESS C OMMUNICATION H OW W IRELESS F ITS I N Fiber network is 95% installed Needed Temporary connection Most critical equipment is IP based Need High Throughput Cost effective Ease of installation and configuration

4 W IRELESS C OMMUNICATION T HE D ESIGN OF W IRELESS Researched 6 different manufacturers Wanted Point 2 Point Encryption Ethernet Bridge PTZ standard is NTSC, needed to covert to IP or purchase new PTZ

5 W IRELESS C OMMUNICATION M AKING THE C HOICE Maxstream Xpress Ethernet Bridge Throughput : 15 Mbps Interference possible on the 900 Mhz $390 per pair of modems Needed in house Design for Antennas Yagi antennas - 40 miles Line of Sight Low Loss cable with 50 Ohm impedance Paul Coffelt, PE - ITS Engineer

6 W IRELESS C OMMUNICATION M AXSTREAM

7 W IRELESS C OMMUNICATION F IELD D EVICES

8 W IRELESS C OMMUNICATION E NCODERS - D ECODERS Convert NTSC to MPEG Or Motion JPEG IP addressable Web based IP programming Single or 4 video signal versions Ethernet with Serial port for control Up to 30 fps possible With Wireless we use 3 fps per channel
