1.0 RF Engine OEM Modules
RF Engine modules meet IEEE 802.15.4 specifications. These modules provide a
low power, highly reliable sensor wireless network at very low cost. The modules provide
up to 16 channels of operation in the ISM 2.4GHz frequency band. The are two versions
of modules. One version has an external power amplifier. This module will be referred to
as RF Engine with amplifier. The other module has no external power amplifier and is
referred to as RF Engine without amplifier.
