• The potential to place hardware near entrances or windows for better GSM coverage
• The number of repeaters to install
• The optimal locations for the repeaters, within a 25 m line of sight of the gateway or another
repeater
• If you need to install repeaters on opposite sides of a wall to improve signal strength
• The location of doorways where you can install repeaters if existing walls impede the signal
strength
Note:
• It is advisable to provide a separate, independent, and clearly tagged power supply for the
gateway and repeaters.
• Install the gateway and repeaters at a height that is free of interference from staff and
customers.
• Do not position hardware above ceiling tiles.
