Radio system i.e. guest system, for operation in flexible connection line-radio cell, has transmitter sending power, where frequency bands of host system are divided into sub-frequency bands in which operation of host system is not impaired
摘要
<p>The system has a transmitter for transmitting power that is below a preset threshold value. The system operates in a frequency band of a host system and monitors the frequency band of the host system within a radio cell. The system divides the frequency bands into sub frequency bands, in which operation of the host system is not impaired. The system functions only in a small region. The host system is monitored in transmission breaks of the system by utilizing band spread transmission methods. The radio cell is provided with a measurement receiver.</p>
