Chapter 2. Tag Operation 4 Recommendations for optimizing battery lifetime: Scan only channels that are in use in your network. Typically, because of overlap of channels, there are only 3 or 4 channels in use from the 11 (or 13/14) available. Use single SSID whenever possible. Using multiple SSIDs requires additional network scans and decreases battery lifetime. When using dynamic IP addressing tune the DHCP server to provide very long lease times for tags.
