First Claim
1. Apparatus for manufacturing a base station cabinet temperature at least at a minimum temperature level, said apparatus comprising:
- a signal generator for generating a transmit signal of a selected signal frequency, for at least a selected time period;
a controller coupled to said signal generator, said controller for selectively generating a control signal to cause said signal generator to generate the transmit signal;
an amplifier coupled to said signal generator to receive the transmit signal generated at said signal generator, said amplifier for amplifying the transmit signal, said amplifier further generating thermal energy as a by product of amplification of the transmit signal; and
a transmit filter coupled to said amplifier to receive the transmit signal, once amplified by said amplifier, said transmit filter for filtering the transmit signal, thereby to prevent transmission thereof.

Abstract
Apparatus, and an associated method, facilitates maintenance of ambient temperature levels within a radio base station cabinet above a minimum temperature level. During periods of low activity at a radio base station, signals are applied to a power amplifier of the transmitter portion of the radio base station. Thermal energy is generated as a byproduct of amplification of the signals provided thereto. The signals are selected such that the signals are rejected by filter circuitry, such as the duplexer filter circuitry, of the radio base station. Thereby, thermal energy is generated but amplified signals are prevented from being transmitted by the radio base station.

11. In a radio device positioned at a cabinet at least partially to enclose the radio device, an improvement of apparatus for at least selectively increasing a temperature level at the cabinet, said apparatus comprising:
a controller operable at least when the temperature level at the cabinet is below a first threshold, said controller for generating a control signal to cause the radio device to generate an amplified signal of a selected frequency, the selected frequency beyond a pass band of a transmit filter of the radio device, thereby to prevent transmission of the amplified signal, thermal energy generated as a byproduct of formation of the amplified signal for increasing the temperature levels at the cabinet. - View Dependent Claims (12, 13, 14, 15)
