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.
