102. Robust and reliable communications are critical to managing any event and become critical in an emergency.

103. Adventure sport events often take place in areas where there is no mobile phone network coverage. Mobile phones can also suffer from signal interference, particularly where large numbers of people are present and using the networks. It is, therefore, important to consider alternative communication methods, such as setting up a radio network, to ensure organisers can maintain contact with their event teams across the entire area. 

104. Satellite PTT radios, satellite phones and satellite internet connections that enable WIFI calling phones have a place in some events, but the cost of using these is significant.

105. It is also important to test the communication systems in advance of the event so that the scope and limitations are understood. While it may not be possible to achieve 100% coverage, it is important to understand where event personnel can and cannot communicate within the Event Area so that any gaps can be manage appropriately.

106. Wherever possible a ‘closed network’ where all messages are routed through ‘Race Control’ is recommended. This allows the personnel in the Race Control to monitor the event as it unfolds and coordinate resources and staff effectively. 

107. Large events may have a management structure where staff cascade communications through their supervisors, but the ability to cut straight through to Control in an emergency is recommended.

108. Larger events may refer to the ‘Race Control’ as the Emergency Liaison Team (ELT) and this should include representatives responsible for all aspects of the event.

109. The Race Control team should maintain a log of all critical decisions and actions during the event. This may be as simple as written notes through to sophisticated digital systems that integrate and log all communications and tracking/timing data.
