7 RF Specifications
The following content is the description of module radio frequency performance.
7.1 Technical Specification for UMTS Mode Radio Frequency
7.1.1 Maximum Transmission Power
In the normal test environment, UMTS 2100/1900/850/900/(1700)MHz maximum output power meets
the requirement in Table 7-1. The test values are the average of some test samples. Under different
environments, the testing results might be slightly different. Take the actual situation as the reference.

7.1.2 Receiving Sensitivity
UMTS 2100/1900/850/900/(1700)MHz receiving sensitivity meets 3GPP TS 34.121 protocol
requirement. Under the specification that BER does not exceed 0.001, it meets the requirement in Table
7-2. The test values are the average of some test samples. Under different environments, the testing
results might be slightly different. Take the actual situation as the reference.
