Abstract

En un sistema de telecomunicaciones, en el que se intercambian senales entre una estacion de base y una terminal radioeléctrica fija, vía una unidad de antena, esta ultima se instala separada de la terminal radioeléctrica fija, la cual incluye partes radioeléctricas y un amplificador. Para la unidad de antena se dispone de varias configuraciones posibles, eligiéndose la configuracion sobre la base del entorno radioeléctrico del sitio de instalacion. La unidad de antena puede incluir un cable de antena y una antena. La unidad de antena también puede incluir un amplificador de antena y un dispositivo para determinar el modo de operacion de la terminal radioeléctrica fija. La unidad de antena puede incluir, además, un conversor de frecuencias para convertir las senales de alta frecuencias recibidas en senales de baja frecuencia o bien, las senales de transmision de una baja frecuencia a una alta frecuencia, segun el modo de operacion. El modo de operacion se puede determinar usando un detector de rampa para detectar una rampa de transmision. Como alternativa, se puede usar una senal de control enviada desde la terminal radioeléctrica fija, como indicacion del modo. El amplificador de la terminal radioeléctrica fija puede ajustar la potencia de salida, teniendo en cuenta un factor de amplificacion constante conocido de un amplificador de antena lineal o no lineal o bien, puede hacerlo el amplificador de antena de la unidad de antena, sobre la base de los comandos de control recibidos de la terminal radioeléctrica fija o la estacion de base. Los comandos de control de potencia pueden contener tanto valores absolutos como valores relativos a la potencia de salida de la corriente.In a telecommunications system, in which signals are exchanged between a base station and a fixed radio terminal, via an antenna unit, the latter is installed separately from the fixed radio terminal, which includes radio parts and an amplifier. Several possible configurations are available for the antenna unit, the configuration being chosen based on the radio environment of the installation site. The antenna unit may include an antenna cable and an antenna. The antenna unit may also include an antenna amplifier and a device for determining the operation mode of the fixed radio terminal. The antenna unit may also include a frequency converter to convert the received high frequency signals into low frequency signals or, the transmission signals from a low frequency to a high frequency, depending on the mode of operation. The mode of operation can be determined using a ramp detector to detect a transmission ramp. Alternatively, a control signal sent from the fixed radio terminal can be used as an indication of the mode. The amplifier of the fixed radio terminal may adjust the output power, taking into account a known constant amplification factor of a linear or non-linear antenna amplifier, or the antenna amplifier of the antenna unit may do so, on the basis of the control commands received from the fixed radio terminal or the base station. The power control commands can contain both absolute values and values relative to the power output of the current.
