Introduction
The GSM Radio Frequency Unit (GRFU) is a Radio Frequency (RF) unit based on the multicarrier technology. GRFUs are installed in the indoor macro base station (including the BTS3900 and the BTS3900L) and the outdoor macro base station (namely, the BTS3900A). They are usually used in scenarios requiring large capacity. A GRFU supports a maximum of six carriers. a.1 shows its exterior. Figure a.1 Exterior of the GRFU
