ROC vs. CEC

• The Roll-Out Configuration (ROC) Node B provides customers with a lower cost Node B with relatively low downlink air-interface capacity. This is relative to the Capacity Enhanced Configuration (CEC)

• The ROC configuration shares WPA between sectors rather than dedicating a WPA to each sector

• 1+1 ROC Node B have a single 20 W WPA or a single 40 W WPA to share between sectors

• 1+1+1 ROC Node B have a single 20 W WPA or a single 40 W WPA to share between sectors

• The same downlink signal is transmitted by all ROC sectors

WPDA WPDB

ROC – Wideband Power Divider

• Wideband Power Divider A (WPDA) is used for 3 sector ROC and WPDB is used for 2 sector ROC

• The WPDA is a passive component and has an insertion loss of 5.6 dB compared to the ideal 3-way splitter loss of 10*LOG(3) = 4.8 dB

• The WPDB is a passive component and has an insertion loss of 3.6 dB compared to the ideal 2-way splitter loss of 10*LOG(2) = 3.0 dB

• The WPD insertion loss reduces the transmit power available at the Node B antenna connector

• The WPD unit fits into an empty WPA slot within the Node B cabinet

Metrosite 50 – Introduction

• Nokia MetroSite 50 BTS support 1+1+1 ROC, 1+1 ROC, 2-Omni and 1-Omni configurations.

• MetroSite 50 BTS have single 54 W WMP (Power Amplifier) to share between sectors.

• MetroSite 50 BTS is suitable for locations with limited space, such walls, tunnels and attics

• The small size and light weight of MetroSite 50 BTS enable wide range of installation locations to be used. The cabinet can be installed both indoors and outdoors, on a wall or a pole, in a vertical or horizontal position.

3-way splitter (or 2-way in case of 1+1 ROC) divides power in DL

ROC Concept – Metrosite 50

• MetroSite support both Omni and ROC configurations (1+1 ROC & 1+1+1 ROC)• Instead of dedicating own Power Amplifier (WMP) for each sectors, ROC

configurations shares WMP between sectors in DL

• MetroSite have single 54 W WMP to share between sectors. And due to this limitations, it is not possible to upgrade MetroSite ROC to CEC

• The Same DL signal is transmitted by all ROC sectors

• 1+1+1 CEC has 3 cell and 3 sectors

• 1+1+1 ROC has 1 cell and 3 sectors
