Page 7: General
ease of installation and use – the pMDDL2450 module uses a subset of standard AT style commands, very similar to those used by traditional telephone line modems. -
Page 8: Output Power Level
While the typical application for the pMDDL2450 is to provide a short- to mid-range wireless communications link between DTEs, it can be adapted to almost any situation where an asynchronous serial interface is used and data intercommunication is required. -

3. Installation 3.0 Overview The pMDDL2450 complies with FCC part 15 at the modular level for operation in the license-free 2400-2483.5 MHz ISM band. This chapter provides guidelines for installing and deploying equipment which incorporates the pMDDL2450 module. 3.1 Estimating the Gain Margin... - Page 10 Figure 1 Gain Calculation The power level has been set to 30dBm (1W) on the transmitter, and the receiver sensitivity for the pMDDL2450 is -108dBm. System gain would be calculated to be: 30 - 2 + 6 + 3 - 2 + 108 = 143 dB.
