1 Introduction

The MBSC-C Fiber Optic Coverage System is used to extend wireless coverage to specific areas in building(s), or throughout a complex zone. The mBSC product family offers a flexible, scalable, modular platform to improve signal quality and enhance the services to meet the increasing demands.

The MBSC-C system components include a Host Unit (HU) and a Remote Node. Each Host Unit can feed up to eight multi-band Remote Nodes, each utilizing a single fiber. A Remote Node can accommodate between one and five single-band bi-directional amplifiers (Remote Units) – install only the bands required at the time of deployment. As requirements change, additional single-band units can be easily installed in the field. This modular architecture provides optimum implementation flexibility, reduces initial cost, and defers further investment until required.

1.1System Solution Block Diagram

The MBSC-C platform allows flexible system deployment to support mixed mode 700~2700MHz services in SISO and/or MIMO configurations.

3 System Overview and Unit Description

3.1System Overview

The MBSC-C system is a multi-operator, multi-band and multi-technology coverage system that provides in-building / venue coverage for up to five operating bands. Large buildings typically interfere with the transmission or reception of cellular phone system signals by imposing high attenuation losses on the RF signal. The mBSC system is designed to overcome these losses which otherwise make cellular communications within buildings or structures difficult or impossible. With the mBSC system, cellular phone RF signals can be distributed to the interior areas of any building or structure to eliminate dead spots and improve reception.

The MBSC-C coverage solution interconnects to, and extends, the wireless service provider base station equipment (BTS) and service antennas. A functional overview is illustrated below.

Figure 3mBSC System Functional Overview

The mBSC system provides downlink signal amplification and uplink sensitivity improvement for multi-band RF signals, which may be comprised of multiple carriers and multiple standards.

The Host Unit provides the input interface for RF signals from a base transceiver station (BTS). The Host Unit converts the RF signals into a digital format and distributes the digitized signal over fiber to multiple output ports. An optional Multi-operator Point-of-Interface (POI) combines multiband BTS inputs from several operators into a single TXin / RXout interface to the Host Unit. Refer to “SP-MBSC-C-POI” for additional details.

The Remote Node receives the optical signals from the Host Unit, converts the signals back into RF and interfaces with the service antennas to amplify the RF signals throughout the building. The Remote Node is typically wall-mounted within an equipment room.

mBSC0850i-005-RUCM11	April 15, 2013
	Page 4

mBSC-CM RUM

3.1.1 Interface with BTS

The Host Unit is typically installed close to the wireless service provider BTS equipment. In the downlink path the Host Unit combines RF signals from up to 5bands and feeds the combined signal to a fiber-optic transceiver for transmission to the interconnected Remote Node(s).In the uplink path the Host Unit converts a composite multi-band optical signal into independent RF signals for interconnection with the BTS receive elements.

3.1.2 Interface with Cellular Phones

The mBSC Remote Node interfaces with the cellular phones through the service antennas. In the reverse path, the Remote Node receives RF signals from cellular phones. In the forward path, the Remote Unit transmits the RF signals to the cellular phones. A bi-directional antenna is connected to the mBSC Remote Node to transmit and receive RF signals from the cellular phones.

3.1.3 Fiber Optic Transport

The Host Unit is connected to each Remote Node over a single optical fiber. The optical fibers must be terminated withE2000/APC connectors for connection with the Host Unit and the Remote Node. For MIMO operation a duplicate set of BTS interface, fiber transmission, and remote node equipment is required, along with an additional optical fiber.

3.1.4 Powering

The Host Unit is powered by -48V DC which is supplied by either the equipment room power distribution cabinet or an AC/DC converter. The Remote Node is powered by 110/220VAC, 50/60Hz power which is supplied through a power supply distribution junction box.

3.1.5 Cooling

The Host Unit is cooled through cross-convection without fans.

The Remote Node contains multiple single-band Remote Units, which are cooled through continuous air flow fans mounted on the top of each singe-band unit. A minimum of 200mm (7.87 inches) of clearance space must be provided on both the top and the bottom sides of the Remote Node for air flow.

An alarm is provided that indicates if a high temperature condition occurs.

3.1.6 Fault Detection and Alarm Reporting

LED indicators are provided on the front panel of the Host Unit to indicate if the mBSC system is operating as expected (normal) or if a fault is detected. In addition, normally open and closed alarm contacts (for both major and minor alarms) are provided at the Host Unit for connection to a customer provided external alarm system.

The mBSC system also includes a standalone (optional) Element Management System server, which interconnects with each Host Unit in a multi-system deployment, and is used for system configuration, status monitoring, and SNMP alarm reporting / management.

3.3Remote Node Description

The Remote Node serves as the remote interface unit for the fiber optic mBSC system. It is a multi-slot chassis and consisting of 12 slots numbered from left to right, enclosure for up to five RUMs (Remote Unite Module), RTM (Remote Transmission Unit), RPM (Remote Power Module) BCM (Band Combiner Unit) and Fan. The Remote Node provides the following basic functions:

RF interface to the mobile end-systems via an external service antenna

Optical interface to the Host Unit FIU

Conversion of the forward path(downlink) optical signal to original RF signal

Conversion of the reverse path(uplink) RF signal to an optical signal

Transports alarm status over the optical fiber

Supplies in-band messaging between the Host Unit and the Remote Node for Remote Node alarms and configuration

3.3.1 BCM Enclosure

The BCM module provides function:

Combines the RF signals from each single-band RU Enclosure for duplex interconnection with the service antenna

3.3.2.1.1Multi-Carrier Power Amplifier (MCPA) Modules

The MCPA Module is the heart of the mBSC RUM Enclosure. The MCPA Module boosts the BTS forward link transmission signal. Operating on28VDC input, the MCPA Module produces 5W composite RF power for each band (measured at output of the antenna combiner).

The mBSC system provides linear amplification of multi-carrier, mixed-mode signals in the 700MHz, 850MHz, 1900MHz, 2100MHz and 2600MHz frequency bands with the respective RU’s.

3.3.2.1.2Duplexer

The duplexer is used to make the bi-directional signals into simplex signals and provides sufficient isolation

3.3.2.1.3CPU(Central Processing Unite

The CPU provides communications and monitors with power amplifier module or other functional module.

3.3.2.2Mounting

The single-band RUM enclosure is plug in REMOTE NODE multi-slot chassis.

3.3.2.3RF Connection

The RF signal connections with the single-band enclosure are supported through two QMA female coaxial connectors and one N female connector. The two QMA female connectors are used for coaxial cable connection (RF jumper) of the Tx and Rx RF signals between the RTM enclosure and the single-band RUM enclosure. The N female connector is used for coaxial cable connection of the amplified duplex Tx/Rx RF signal to the BCM enclosure.

3.3.2.4Cooling

The single-band RUM enclosure is cooled by cooling fans in the bottom of the casing. A minimum of 200mm (7.87 inches) of clearance space must be provided on both the top and the bottom sides of the Remote Node for air convection.
