Zebra Devices Operating with Standard Power

This section describes how information elements advertised by an Access Point dictates how a device realizes the AP mode of operation.
The device determines the Access Point mode of operation (LPI, SP or VLP) from the information elements advertised by the AP in beacons. These information elements are examined by the device to determine the operating transmit power:
  • Country Element (ID 7)
  • Power Constraint Element (ID 32)
  • Transmit Power Envelope Element (ID 195)
The device calculates the minimum allowed transmit power from the above information elements as well as its internal regulatory power tables.
When connected to a Low Power Indoor AP, the device operates at or below the power levels advertised by the LPI AP.
When connected to a Standard Power AP the device operates at 6 dB lower than the SP AP’s authorized power level established by the AFC system. More about the Standard Power operation is explained in the Standard Power section, along with the 6dB reduction requirement.
