3 Detailed Description

APCD-LM043-4.0 31

The CCU and EUM transmit power can each be set to +15 dBm (LOW power setting) to

address special or regional applications of the LMS4000, or for bench testing.

Receive Sensitivity

The receive sensitivity (received signal required to attain a raw data BER of 10

-5

or better

using 1000-byte packets) of the CCU and EUM is <

-86 dBm, measured at the unit’s RF

connector.

Antenna Connector

The RF connector used on the CCU and EUM is a WaveRider-proprietary connector. As noted

above, the use of a proprietary antenna connector is mandated by FCC requirements for a

unique RF connector on ISM products.

Antenna Control (EUM)

A DC voltage (5 VDC or 7.5 VDC) is applied to the EUM RF connector for powering and

controlling the WaveRider diversity antenna. One beam pattern is selected if the voltage is 5

VDC. A second beam pattern is selected if the voltage is 7.5 VDC.

CAUTION: The EUM sends DC power and control voltages

through the RF connector to the switched-beam diversity

antenna. You must use WaveRider-approved indoor or outdoor

antennas; otherwise, you could inadvertently short out the DC

voltage and damage the EUM. Contact WaveRider Technical

Support for a list of approved antennas.

Propagation Path

CCU and EUM radios and antennas provide the basis for excellent radio propagation in both

line of sight (LOS) and non line of sight (NLOS) EUM installations. Radio propagation in the

902 – 928 MHz ISM band is superior to propagation in higher ISM bands for several reasons:

• Lower free space loss

• Lower cable loss

• Lower vegetation loss

• Better wall and glass penetration

• More signal recovery from diffraction

• More signal recovery from reflections

Radio line of sight exists when there is a clear optical path between the CCU and EUM

antennas, as well as adequate clearance of the path over terrain, foliage, and buildings. This

clearance requirement is called the Fresnel clearance. The required clearance varies along

the path and reaches a maximum at the path midpoint. If you have a path with Fresnel

clearance, the loss between the antennas is generally equivalent to free-space loss and can

be readily calculated.
