  • Page 5: General

    The small-size and superior RF performance of this module make it ideal for many applications. While a pair of MHX2421 modules can link two terminal devices (“point- to-point” operation); multiple modules can be used together to create a network of various topologies, including “point-to-multipoint”...
  • Page 6: Output Power Level

    While the typical application for the MHX2421 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.

  • Page 8: Installation

    Qualified and experienced personnel must carry out the installation, removal or maintenance of all antenna components. The MHX2421 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 MHX2421 module.
  • Page 9 Figure 1 Gain Calculation The power level has been set to 30dBm (1W) on the transmitter, and the receiver sensitivity for the MHX2421 is -108dBm. System gain would be calculated to be: 30 - 2 + 6 + 3 - 2 + 108 = 143 dB.
