Fiber-Fed DAS Distribution Configuration

The goal of the DAS is to faithfully deliver the critical radio message to the first responder in the target coverage area either via off-air antenna or direct feed from a donor Base Station/Radio Repeater. Uplink and downlink are balanced to assure reliable bidirectional communications. For simple systems, off-air signal pickup is typically less costly than a direct feed, but is also subject to any donor signal quality variation due to interference, and fading. For more complex systems, this cost scenario is quickly reversed, and in extreme RF signal environments, a direct feed may be mandated. In other cases, the use of channelized Headend Repeater Units (HRU) may be required to help maintain the desired off-air RF signal quality in the presence of a cluttered frequency spectrum. The FTU accepts the downlink RF signal and converts it to light for delivery via singlemode fiber to one or more RRUs selected according to the DAS coverage requirements. The antenna network itself is designed to provide the required received signal level throughout the target coverage area. In the uplink direction, the RF signals received from portable radios within the DAS coverage area are amplified by the RRU and converted to light. These optical signals are received in turn by the FTU at the Headend, converting them back to RF for amplification by the HRU (and/or conditioning by the BSU), and ultimate delivery to the donor signal source.

SYSTEM ARCHITECTURE The diagram below illustrates a simplified distribution network within a building for coverage of both commercial and public safety bands. The commercial base station hotels (BTS) are connected to TE’s Universal Host unit and the Public Safety BDAs are connected to FTU. These Head-end Units then interface with the FTU Fiber Transceiver Units which convert the Radio Frequency (RF) signals into optical signals. The signals are then distributed through fibre optic cable to a series of multiple-band RRU remote units installed throughout the building. The signal is then re-converted back to RF at the remote units for distribution through the passive portion of the DAS which includes coaxial cables, splitters and antennas installed in the areas of the facility requiring coverage.

NETWORK SOLUTIONS /// TE PUBLIC SAFETY DAS

HEADEND CONSIDERATIONS In general, two options exist at the Headend (also known as the donor location). The owner, or Agency having jurisdiction, often provides a base station for direct connection to the DAS. Unlike as in cellular networks, this provides additional coverage (not additional capacity) in simulcast systems. Directs connection also avoids potential interference and overloading of the an outdoor macro network directly handles the high RF output power of the Base Radio and splits and combines the signals in both directions for interfacing with the Fiber Transceiver Unit (FTU). In cases where local radio coverage near the head-end is required, the IHU provides a high power output to drive the local passive DAS along with the fiber output for the remote Repeater units. In an off-air scenario, the Headend Repeater Unit (HRU) provides the additional functions needed for over the air reception and transmission of the DAS signal such as low-noise receiver, and high power transmitter. This donor antenna is pointed at a remote Base station transmitter/ receiver. The HRU provides the proper filtering to maintain signal integrity - both uplink and downlink. Current public agency

requirements demand the highest level of filtering to assure the integrity of their First Responder radio communications - a task perfectly suited to TE’s Headend Channelized BDA. This unit uses advanced Digital Signal Processing to distortion free fi ltering of individual radio channels – rather than wide filtering which simultaneously passes multiple radio channels. Wide filtering, or broadband filters, can pass intermodulation spurs and other

interference. A Channelized DSP filter will eliminate all out-ofband interference and mitigate intermodulation distortion which can otherwise hamper radio communications. The above Headend equipment is then interfaced with the FTU. The FTU converts the radio frequency signal to an optical signal in both directions, uplink (from handset to base station) and downlink (from basestation to handset).

REMOTE UNIT CONSIDERATIONS The fiber infrastructure then connects to the RRU, or in many cases multiple RRUs in remote locations. Intermediary optical drops can be configured depending on the layout of the facility or campus. If the system is large enough, Secondary Headends may be required to manage the signal flow and optimize system performance. The secondary head-end is used to managed large networks and to achieve the highest level of

performance and reliiability. Features such as noise-squelching can be implemented at this level to protect the base station head-end from excessive noise that would desensitize the uplink receiver. This is a critical feature that is needed to maintain the maximum coverage area in large DAS and to assure first responders ubiquitous communications. Additional filters, low-noise amplifiers and power amplifiers boost the signal

for clean transmission via the distributed antenna system. The DAS itself may consist of an array of discrete antennas, used where the target coverage area is wide, such as buildings, rooms, and arenas; or radiating cables - often used for coverage of long thin areas such as tunnels or walkways, or judicious combinations of the two. TE can engineer a coverage extension solution for any space your clients or users may have.

PRODUCT COMPONENTS BSU: Base Station Interface Unit Downlink RF signals levels from the HRU or Basestation typically exceed the maximum input level for Fiber Transceiver Units (FTUs). The primary function of the downlink path of the BSU is to condition, or attenuate and split, RF signals prior to the RF-to-optical conversion by the FTU. The BSU also conditions RF signals from the FTU in the uplink path to the HRU or Basestation. Downlink RF signals are split from one common port to multiple ports that interface with one or more FTUs. Uplink RF signals are combined from multiple ports to one common port that interface with the HRU or Basestation. Multi-port unit provides very flexible connectivity options for interfacing with Basestation/repeater, HRU, and FTU. Built-in adjustable attenuators are available on the rear panel as shown.

HRU: Headend Repeater Unit TE’s equivalent to the BDA. The HRU is the interface to the donor antenna and is located at the Headend of any in-building offair coverage solution. The HRU amplifies RF frequencies in both the downlink and uplink paths with duplexers that allow both downlink and uplink frequency bands to co-exist on a single DAS.

FTU: Fiber Transceiver Unit The FTU converts downlink RF signals to light and uplink optical signals back to RF. The FTU feeds one or more Remote Repeater Units (RRU) via single mode fiber-optic cable. The FTU interfaces with an HRU or a Basestation through the BSU. Fiber Transceiver Unit converts RF to light and back. Can feed up to four (4) RRUs. Front panel displays Alarm Transmitter and Receiver Alarm Status.

RRU: Remote Repeater Unit The RRU is equipped with an internal optical transceiver that converts the downlink optical signals to RF and the uplink RF signals to light. The downlink RF signals then pass through a power amplifier and are combined with the uplink RF signals using a duplexer. The downlink and uplink are available on the “DAS” RF port on the bottom of the unit. The uplink RF signals are fed into the fiber-optic transceiver inside the unit where they are converted to light. The downlink optical signals are fed optically into the RRU via the “Optical In” port. The uplink optical signals are sent from the “Optical Out” port. The fiber-fed Remote Repeater Unit connects to the FTU via singlemode fiber link. The broadband RF output port of this unit connects to the network of antennas collectively known as the DAS. The RRU is optionally available in a NEMA4 or 4X housing for NFPA compliance.

NETWORK SOLUTIONS /// TE PUBLIC SAFETY DAS

PRODUCT COMPONENTS IHU: Integrated Headend Repeater Unit Unique in the industry, the IHU incorporates all the essential ingredients of an HRU (BDA) and FTU in a single enclosure. This includes combining/splitting sub-system, fiber optic transceivers, as well as separate coaxial RF ports for local DAS connections, making it arguably the most cost-effective off-air Headend solution available. This Headend Repeater combines the fiber interface functions of the FTU with the off-air gain and output power of the HRU - all in one package. Up to four (4) RRUs may be connected. Discrete RF (Tx/Rx) ports are also available for local coaxial DAS connections.

CRRU: Compact Remote Repeater Unit As the name suggests, the CRRU is a small form-factor fiber-fed Remote Repeater Unit designed for lower RF power (and lower cost) applications. Equipped with an internal optical transceiver, operational concepts are similar to those of its bigger brother, the RRU. However, in the interest of saving space, no internal duplexer is included exccept for higher frequency bands. Small form-factor unit designed for lower RF power applications. Built-in fiber transceiver. A fiber transceiver is built-in and an external duplexer is required at lower frequency bands for a single DAS infrastructure.

Advanced (NMS Compatible) FTU The Advanced FTU provides extreme flexibility via modular construction. Plug-in modules provide all functions including FTU cards, and even redundant power supplies. TE NMS compatibility ensures end-to-end network visibility.

Headend Channelized BDA This DSP-based channelized repeater ensures robust system operation in hostile RF environments while offering extreme configuration flexibility. A built-in web interface is provided for easy configuration, operation, and troubleshooting.

PUBLIC SAFETY NETWORK MANAGEMENT SYSTEM (NMS) The Network Management System is a comprehensive monitor and control system with GUI integration and optional SNMP v2 connectivity to a Network Operations Center (NOC). It is designed to provide extremely flexible and scalable end-to-end connectivity between the NOC, Headend and all Remote Units and other TE elements comprising a Distributed Antenna System (DAS).

Flexible and Scalable Design * GUI with customizable ‘Home Page’ providing an immediate visual indication of the overall system event status. * Extremely cost-effective solutions using serial communication with remote units via Ethernet: over your existing network or over the DAS fiber plant by TE. * Local NMS access is provided via USB port, facilitating on-site test and setup activities at a Remote Unit. * On-board microcontrollers included in each of the major DAS components report equipment status and support overall monitor and control capabilities. * Optional SNMP v2 compatibility The essential elements comprising the NMS are illustrated in Figure 1, below. Note that this platform can be expanded by adding more FTU rack-mount modular chassis. These are daisy-chained for NMS purposes, and this approach is scalable to accommodate extremely large systems. A single USB Gateway will support up to 24 connected elements. An element is an FTU (Fiber Transceiver Unit), HRU (Headend off-air pickup Repeater Unit), BSU (Base Station signal conditioner), or any of various other local units.

NETWORK SOLUTIONS /// TE PUBLIC SAFETY DAS

Thus, larger systems can be accommodated simply by partitioning the elements in sub-groups of maximum size 24, each with its own Gateway.

Key NMS Features The TE NMS system home page is a summary representation of the overall system, from head-end to remote units. It can be customized and it displays three fundamental status levels of your DAS elements: 1. Element OK, 2. Element Failed, and 3. Service/Standby Mode This way the NMS operator will be made aware of any status change in the overall system and which areas are affected. The NMS GUI provides a visual representation of the current status of the system, including events. Where the events are Alarms generated by the elements (e.g., FTU). The degree of severity is also captured, and is classified as Minor, Major or Critical. These basic terms assist the maintainer in gauging the degree of urgency required in their response to a given alarm event. Any given element may be accessed simply by ‘drilling down’ through the tree structure until the desired element is reached.

Event Notification and Escalation NMS event notification via SMS or Email is provided as is a user-configurable escalation procedure to help ensure timely attention to alarms and maximization of system up-time.

SNMP NMS compatibility with an enterprise-class NOC, or third-party service provider, is assured by SNMPv2 compliance. SNMP Traps and NOC connectivity are provided via the local server and a secure Internet connection.

Security Access to the NMS is controlled by the use of User Accounts, each with an associated User ID and Password. The NMS application supports two types of users: Administrator and Operator. The Administrator can create the NMS Tree, manage the variables, the Users, e-mail settings, master data, the device, SNMP, and so on. Whereas an Operator can only view and customize the NMS Tree, Network Management Summary and details of variables through the Control Panel.

Down-stream Control In addition to alarm reporting and alerting (upstream data), the system allows a user (with authorized access via password), to control settings in the system - all the way out to the RRUs. These controls include: RF Gain level settings for both uplink and downlink, element shutdown (e.g., turn off an RRU), reset the remote server, update firmware, etc.

Easy to Use What matters most to the user of any NMS are ease-of-use, and timely, unambiguous notification of the occurrence of events. Web browser access to any element in the system is available, at both the equipment and server levels. GUI screens are uncluttered and simple to interpret, and notification of alerts is clear.
