Figure 1. Access point placement in a large system. Place access points that share a channel at least 50 m (approx. 160 ft) apart. Minimize the number of access points that use the same channel. For example, in a system that uses 16 access points, you should assign 2 access points on each channel. If an access point has its own dedicated channel, you can place it freely anywhere on the site. Additional placement recommendations Figure 2. Access point distribution example in a large building. If the site has more than one monitored space, place access points that share a channel in different spaces. Maintain the recommended 50 m (160 ft) minimum distance between channel sharing access points. Figure 3. Access point distribution example in a multi-floor building. Use concrete walls, floors, and other heavy structures to limit the range of channel sharing access points. Data loggers that are in range of channel sharing access points should have a strong signal from only one of them. This helps to prevent situations where simultaneous transmissions block the connection.
