required to take responsibility of the module through a change in FCC ID or new application. The FCC ID of the
module cannot be used on the final product. In these circumstances, the host manufacturer will be responsible
for re-evaluating the end product (including the transmitter) and obtaining a separate FCC authorization.
Antennas
Antenna specification are as follows:
• Type: External antenna connector
• Gain: 2.33 dBi
This device is intended only for host manufacturers under the following conditions:
• The transmitter module may not be co-located with any other transmitter or antenna.
• The module shall be only used with the external antenna(s) that has been originally tested and certified with
this module.
• The antenna must be either permanently attached or employ a ‘unique’ antenna coupler.
As long as the conditions above are met, further transmitter test will not be required. However, the host manufac-
turer is still responsible for testing their end-product for any additional compliance requirements required with this
module installed (for example, digital device emissions, PC peripheral requirements, etc.).
Label and Compliance Information
Host product manufacturers need to provide a physical or e-label stating “Contains FCC ID: 2AC7Z-ESPC3MINII”
with their finished product.
Information on test modes and additional testing requirements
• Operation Frequency:
– WiFi: 2412 ~ 2462 MHz
– Bluetooth: 2402 ~ 2480 MHz
• Number of Channel:
– WiFi: 12
– Bluetooth: 40
• Modulation:
– WiFi: DSSS; OFDM
– Bluetooth: GFSK; π/4 DQPSK; 8 DPSK
Host manufacturer must perform test of radiated and conducted emission and spurious emission, etc., according
to the actual test modes for a stand-alone modular transmitter in a host, as well as for multiple simultaneously
transmitting modules or other transmitters in a host product. Only when all the test results of test modes comply
with FCC requirements, then the end product can be sold legally.
