What risks are there in operating in a public park?
As none of the short-range devices in a ‘public park’ band is subject to frequency coordination, the risk of unplanned interference between uncoordinated users is always present. There is no coordination between WLANs or between WLANs and other short-range devices sharing the 2.4 GHz band. Interference risk is managed by the combination of class licence technical conditions and equipment design. So, the likelihood of interference is related to whether devices operating at low power will be so close together as to cause interference. WLAN devices are specifically designed to work in environments where there may be significant and uncertain amounts of interference; however, communications range and the rate of information transfer reduce as levels of interference increase. In assessing whether operations in a ‘public park’ would be fit for the intended purpose, users and service providers are encouraged to identify and take into account all possible risks. These would include: • any safe
