h1. RRUS The RRU (remote Radio Unit) is basically an outdoor version of the classic indoor radio units like the [[RUS]]. This provides the advantage that it can be mounted on the top (or at half height) of the tower, reducing the length of the lossy coaxial cables, and extending the length of the front-haul interface. The front-haul distance is limited by signal propagation speeds and is in the magnitude of 40km between RRUS and digital unit. h2. Models h3. RRUS 01 * 1 TX/RX and 1 RX branch * 4 carriers over 20MHz IBW * 20kg h3. RRUS 02 * 2 1TX/RX and 1 RX branch * up to 8 GSM carriers * up to 4 WCDMA carriers * 20/40/60/80/100W RF (more than 20W requires license) * up to 2.5 Gbps CPRI * Weight: 23.5kg h3. RRUS 11 * 2 TX/RX branches h3. RRUS 12 * 2 TX/RX branches * up to 8 GSM carriers * up to 4 WCDMA carriers * up to 2 LTE carriers * 2x10/2x20/2x30/2x40/2x50/2x60W (more than 20W requres license) * up to 2.5 Gbps CPRI * weight: 22.4-26.3kg, depending on band h3. RRUS 13 * 2 TX/RX branches * up to 8 GSM carriers * up to 8 WCDMA carriers * up to 3 LTE carriers * 2x10/2x20/2x30/2x40/2x50/2x60W (more than 20W requres license) * up to 10 Gbps CPRI * weight: 22.4-29.6kg, depending on band h3. RRUS 14 * 2 TX/RX branches * up to 8 GSM carriers * up to three LTE carriers * 2x10/2x20/2x30/2x40/2x50/2x60W (more than 20W requres license) * up to 10 Gbps CPRI * 26 kg h2. Power Supply all RRUS are powered by -48 V DC (-38.0 to -58.5V). There are optional 90-275V AC PSU modules ("PSU AC") that can be mounted on the RRU back.
