  • Wireless Is Simple!

    1. 1. ENCOM Wireless Data Solutions presents Wireless is Simple Principles of Wireless for Traffic and ITS Please note: At the end of this presentation, we will ask for the full name and email of each attendee to provide PDH credit information. For large groups, please provide all individual names and a single contact email.
    2. 2. ENCOM Wireless Data Solutions <ul><li>Supplier of Wireless Networks for over 20 years </li></ul><ul><li>Over 15 Years of Traffic and ITS experience </li></ul><ul><li>Only wireless company specific to traffic and ITS </li></ul><ul><li>Thousands of radios deployed in Traffic controller cabinets throughout North America </li></ul><ul><li>Research and development for new radio products ongoing </li></ul>
    3. 3. Presentation Overview Serial Contact Closure Ethernet Wireless Technologies
    4. 4. License Free Bands
    5. 5. Choosing Frequencies 900 MHz 900 MHz <ul><li>Advantages: </li></ul><ul><ul><li>Foliage Penetrating </li></ul></ul><ul><ul><li>Non-Line-of-Sight </li></ul></ul><ul><ul><li>Long Range (up to 20Mi.) </li></ul></ul><ul><ul><li>Does not interfere with Wi-Fi systems </li></ul></ul><ul><li>Cautions: </li></ul><ul><ul><li>Lower bandwidth compared to higher frequencies </li></ul></ul>
    6. 6. Choosing Frequencies 2.4 GHz 2.4 GHz <ul><li>Advantages: </li></ul><ul><ul><li>High bandwidth </li></ul></ul><ul><ul><li>WiFi standard frequency </li></ul></ul><ul><ul><li>Will work on combination with other </li></ul></ul><ul><ul><ul><li>frequencies </li></ul></ul></ul><ul><li>Cautions </li></ul><ul><ul><li>Saturated due to Wi-Fi / Wi-Max </li></ul></ul><ul><ul><li>Affected by weather </li></ul></ul>
    7. 7. Choosing Frequencies 4.9/5.8 GHz 4.9/5.8 GHz <ul><li>Advantages: </li></ul><ul><ul><li>Higher bandwidth </li></ul></ul><ul><ul><li>Less interference </li></ul></ul><ul><ul><li>4.9 GHz Public Safety band </li></ul></ul><ul><li>Cautions </li></ul><ul><ul><li>Clear Line-of-sight required </li></ul></ul><ul><ul><li>Shorter range (up to 10 miles) </li></ul></ul>
    8. 8. Spread Spectrum Technology <ul><li>A transmitting technique where the original signal is spread over a wider area than is required for the data to be sent. </li></ul><ul><li>Benefits: </li></ul><ul><ul><li>Higher throughputs and less bit errors </li></ul></ul><ul><ul><ul><li>Direct Sequence Spread Spectrum (DSSS) </li></ul></ul></ul><ul><ul><ul><li>Frequency Hopping Spread Spectrum (FHSS) </li></ul></ul></ul>
    9. 9. Spread Spectrum Technology <ul><li>Direct Sequence Spread Spectrum (DSSS) </li></ul><ul><ul><li>Spreads its signal by “expanding” the signal over a broad portion of the radio band </li></ul></ul><ul><ul><li>High bandwidth applications </li></ul></ul><ul><ul><li>Wi-Fi, video, OFDM, WIMAX </li></ul></ul><ul><ul><li>Ideal for higher bandwidth apps </li></ul></ul><ul><ul><ul><li>Up to 108 Mbps throughput </li></ul></ul></ul>
    10. 10. Spread Spectrum Technology <ul><li>Frequency Hopping Spread Spectrum (FHSS) </li></ul><ul><ul><li>Spreads its signals by “hopping” the narrowband signal using matching hopping patterns </li></ul></ul><ul><ul><li>Allows to be immune to noise </li></ul></ul><ul><ul><li>Reliable and secure </li></ul></ul><ul><ul><li>Ideal for lower bandwidth apps </li></ul></ul><ul><ul><ul><li>Up to 1.1 Mbps throughput </li></ul></ul></ul>
