Long Range Base Radio Repeater Description

(continued) The measurement data starts with the Wireless Field Units that are battery powered transceivers with integral sensing and signal conditioning. These establish a wireless communication link to the Base Radio; which, in turn, passes the data to the secondary repeater, located in the field, near the Base-Radio. The secondary repeater makes a wireless data retransmission to the primary repeater located where the data is needed. The Long Range Repeater Radio is a powered radio repeater, allowing wireless data transmission at the full FCC power level limit for an unlicensed radio, providing the best possible link strength, the longest range and most reliable connection. . The repeater radio is packaged in a rugged NEMA 4X, watertight housing, with antenna cables of either 10 or 25 feet. This cable allows for remote, optimal, location of the Accutech high-gain “Yagi” and high-gain pole antennas for transmission and reception.

Physical Characteristics

Weather-tight and corrosion-resistant acrylic housing, rated NEMA-4X.

Communication Range

The communication range of any radio is greatly influenced by the characteristics of the installation. Maximum link margin, antenna height and obstacles in the path of the communication are the primary determinants of communication range. Determining the effects of site-based parameters and establishing sufficient link margin emphasize the practical improvements to be realized from conducting a site survey. Antenna placement is a major variable influencing range. Small changes in antenna placement can easily have the effect of doubling the effective working range of a wireless device. Optimal antenna placement is best determined under conditions of actual use. The flexibility afforded by the Accutech remote cable antenna allows an optimal antenna placement, as determined in a survey.
