Encom Wireless Data Solutions has over 20 years of experience providing wireless networks for traffic control, focusing on license-free frequencies like 900 MHz, 2.4 GHz, and 4.9/5.8 GHz. The presentation discusses the advantages and cautions associated with various frequency bands, as well as their applications in traffic infrastructure and wireless technology. Encom's ControlPak software offers user-friendly configuration and diagnostics for managing radio systems efficiently.

4. License Free Bands

5. Choosing Frequencies 900 MHz 900 MHz Advantages: Foliage Penetrating Non-Line-of-Sight Long Range (up to 20Mi.) Does not interfere with Wi-Fi systems Cautions: Lower bandwidth compared to higher frequencies

6. Choosing Frequencies 2.4 GHz 2.4 GHz Advantages: High bandwidth WiFi standard frequency Will work on combination with other frequencies Cautions Saturated due to Wi-Fi / Wi-Max Affected by weather

7. Choosing Frequencies 4.9/5.8 GHz 4.9/5.8 GHz Advantages: Higher bandwidth Less interference 4.9 GHz Public Safety band Cautions Clear Line-of-sight required Shorter range (up to 10 miles)

8. Spread Spectrum Technology A transmitting technique where the original signal is spread over a wider area than is required for the data to be sent. Benefits: Higher throughputs and less bit errors Direct Sequence Spread Spectrum (DSSS) Frequency Hopping Spread Spectrum (FHSS)

9. 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

10. 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
