ENCOM Wireless DataSolutions
Supplier of Wireless Networks for over 20 years
Over 15 Years of Traffic and ITS experience
Only wireless company specific to traffic and ITS
Thousands of radios deployed in Traffic controller cabinets throughout North America
Research and development for new radio products ongoing
Choosing Frequencies900 MHz
900 MHz900 MHz
Advantages:Foliage PenetratingNon-Line-of-SightLong Range (up to 20Mi.)Does not interfere with Wi-Fi systems
Cautions:Lower bandwidth compared to higher frequencies
Choosing Frequencies2.4 GHz
2.4 GHz2.4 GHz
Advantages:High bandwidthWiFi standard frequencyWill work on combination with other
frequencies
CautionsSaturated due to Wi-Fi / Wi-MaxAffected by weather
Choosing Frequencies4.9/5.8 GHz
4.9/5.8 GHz4.9/5.8 GHz
Advantages:Higher bandwidthLess interference 4.9 GHz Public Safety band
CautionsClear Line-of-sight requiredShorter range (up to 10 miles)
Spread Spectrum Technology A transmitting technique where the original signal is spread over a spread over a wider areawider area than is required for the data to be sent.
Benefits:Benefits:– Higher throughputs and less bit errors
• Direct Sequence Spread Spectrum (DSSS)• Frequency Hopping Spread Spectrum (FHSS)
Spread Spectrum Technology Direct Sequence Spread Spectrum (DSSS)
Spreads its signal by “expanding” the signal over a broad portion of the radio band
High bandwidth applications
Wi-Fi, video, OFDM, WIMAX
Ideal for higher bandwidth apps Up to 108 Mbps throughput
Spread Spectrum Technology
Frequency Hopping Spread Spectrum (FHSS)
Spreads its signals by “hopping” the narrowband signal using matching hopping patterns
Allows to be immune to noise
Reliable and secure
Ideal for lower bandwidth apps Up to 1.1 Mbps throughput

Hardwire vs WirelessConduit Design and Installation - Corridor
50 - 75 (2004)
0.02 (1999)
Cost is per mile. Includes boring, trenching, and conduit (3 or 4 inch). Cost would be significantly less for an aerial installation. In-ground installation would cost significantly less if implemented in conjunction with a construction project.
Twisted Pair Installation
