4 Preparing the Range Extender
The PHANTOM 2 VISION range extender is a wireless communication device that operates within the 2.4 GHz
frequency band and is used for extending the effective range of communication between a mobile device
(Smartphone) and the PHANTOM 2 VISION. In an open unobstructed area, the transmission distance can reach
up to 300 meters, but is usually affected by the surrounding environment, such as trees, buildings and other
sources of the same frequency. Before every flight, it is suggested that you ensure the range extender functions
properly. Otherwise you may experience a communication issue with the mobile device and the PHANTOM 2
VISION.
Each range extender has a unique MAC address and network name (SSID), details of which are printed on the
back label as ‘Phantom_xxxxxx’. The ‘xxxxxx’ represents the last six letters or numbers of the MAC address
for the range extender.
