    Identifies strategies that could be used to prevent loss and corruption of

    points for and/or against these strategies

    Sample answer:
    In the multi-player environment, it is necessary that each player’s transmitter has a unique IP
    address or that it is linked to the wireless access point via its own dedicated channel.
    Interference in the wireless frequency band would have to be minimised so that data does not
    get corrupted and lost.
    Increased number of receivers or increased transmission signal strength can decrease the
    chances of signal loss and subsequent data loss. However, these measures could impact
    negatively on the health of the player. The tiny device may also be damaged from a serious
    impact and needs to be securely placed on each player while minimising discomfort to the
    player.
