SpotCell™ 100 Series Application Overview

SpotCell is a band selective, fully adaptive repeater that provides always-on coverage solutions for both 800MHz (cellular) and 1900 MHz (PCS) frequency bands. SpotCell is easily installed in buildings requiring improved wireless coverage. Gaps in wireless coverage due to signal degradation may be a result of terrain, urban environmental influences (buildings, tunnels or underground garages) or user distance from closest cell site coverage area.

Typically, SpotCell 100 series products provide coverage up to 50,000 feet (4600 square meters). See figure 1 for typical application and coverage examples.

Components SpotCell is a complete “out of the box” coverage solution. There are four SpotCell components:

Donor Unit (DU): Provides the air interface to the host base-station, and can be installed in an indoor or outdoor location.

Coverage Unit (CU): Provides the air interface to the mobile handset, and is located within the desired coverage area.

Cable: RG-6 quad-shielded cable connects the Donor Unit to the Coverage Unit, carrying both RF signals and power.

AC Adapter: Provides DC power for the SpotCell. The adapter is connected to the Coverage Unit, and power both the Coverage Unit and Donor Unit.

Installation The SpotCell DU is installed in an indoor or outdoor location where receive signal strength (RSSI) from the base station is adequate for operation.

The SpotCell CU is installed in the indoor location that requires improved coverage.

SpotCell 112 CDMA, 1XRTT

SpotCell uses proprietary, adaptive signal processing technology to implement an adaptive algorithm. This adaptive approach is critical to the product’s rapid installation, and eliminates the need for ongoing maintenance, monitoring and reconfiguration.

SpotCell uses this adaptive algorithm to control system operation in the following key ways:

Installation & Alignment: The adaptive algorithm determines the optimum Base Station alignment and reports this to the user via an LED located on the DU. Once the system is in active mode, the algorithm monitors the selected control or pilot channel for any significant changes in level. If a significant change is detected, a new, optimal control or pilot channel is selected.

Intelligent Gain Control: This determines the gain required using the available BS downlink signal and sets the uplink and downlink gains so that the system is effectively balanced in either direction, while achieving maximum coverage area.

Isolation: The algorithm also determines isolation provided by the environment, and adjusts the system gain to a level that ensures stability under all operating conditions.
