WIRELESS COMMUNICATION HOW WIRELESS FITS IN
Fiber network is 95% installedNeeded Temporary connectionMost critical equipment is IP
basedNeed High ThroughputCost effectiveEase of installation and
configuration
WIRELESS COMMUNICATION THE DESIGN OF WIRELESS
Researched 6 different manufacturers
Wanted Point 2 PointEncryption Ethernet BridgePTZ standard is NTSC, needed to
covert to IP or purchase new PTZ
WIRELESS COMMUNICATION MAKING THE CHOICE
Maxstream Xpress Ethernet BridgeThroughput : 15 MbpsInterference possible on the 900 Mhz$390 per pair of modems
Needed in house Design for AntennasYagi antennas - 40 miles Line of SightLow Loss cable with 50 Ohm impedance
