    1. Wireless Data Technologies MM Clements

    2. WDT 2 Last Week w is used when we want to measure the the rate of change of an angle per unit time - measured in Hertz AM is produced by multiplying the input signal by the carrier wave. There are TWO distinct sidebands produced when using AM. AM is used for low quality broadcasts and is susceptible to induced noise. FM may have many sidebands and is used for high quality broadcasts as it does not suffer badly from noise

    3. WDT 3 This week………. RAN and EDGE networks Base Stations Transmitter types Backhaul network Mobile telephony operation

    4. WDT 4 RAN and EDGE networks Network divided into TWO parts Radio Access Network (RAN) where mobile users interact with the network Edge network The part of the network that interconnects all parts of the network including RANs

    5. WDT 5 Base Stations Transceiver often on a mast, BST Controller to coordinate the action of the base station, BSC Located at the centre of an area that has mobile users Connected to rest of network by backhaul

    6. WDT 6 Sharing Facilities Masts or sites may be shared between mobile providers Cost-effective solution for providers Shared masts tend to be tall to space the transceivers and may require extra planning permission Visual impact of mast may be reduced with disguised BSTs e.g. trees, flagpoles

    7. WDT 7 Disguising Transmitters
