Overview System Description The generic system block diagram below illustrates the typical connectivity between the various building blocks. Note that there is a coaxial (cable) connection between HRU (Fiber-Span s BDA), BSU and the FTU. Headend Equipment DAS Headend Repeater Unit (HRU) Remote Repeater Unit #1 (RRU) Repeater Off-air configuration Direct-feed Configuration Base Station Interface Unit (BSU) Fiber Transceiver Unit (FTU) SM Fiber Cable Remote Repeater Unit #n (RRU) DAS Fiber-Fed DAS Distribution Configuration The goal of the DAS is to faithfully deliver a donor signal received either off-air via antenna, or via direct feed from a donor Base/Repeater Station, to the radio users in the DAS target coverage area. A similar requirement also holds true in the uplink direction. 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 signal 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. 4 3434 Rt. 22W, Suite 140 Branchburg, New Jersey 08876 (908) 253.9080

Applications The diagram below depicts a simplified distribution network within a building and between buildings in a campus environment. For the sake of simplicity, the signal flow in the below-illustrated system will focus primarily on the Headend-to-Remote (downlink) signal direction. Off-Air Donor Signal Pickup Antenna Secondary Headend Primary Headend connected to in-building DAS as well as via fiber to Secondary Headends Remote Repeater (RRU), fiber-fed from Secondary Headend and coax-cable connected to in-building DAS Generic Campus-wide Fiber-fed Coverage Extension System A shown above, the donor signal is received at the roof-top by an off-air pickup antenna. This signal is fed to the Primary Headend for redistribution - locally (within the same building), as well as to all other (Secondary) Headends via optical fiber links. Each Secondary Headend feeds all Remote Repeater Units (RRU) associated with the same building. Several RRUs are installed in each building, and the output of each of these is connected to the respective in-building DAS. See also the System Architecture & Product Family block diagram. 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. As in cellular networks, this provides additional capacity and avoids potential interference and overloading of an outdoor macro network. The direct feed also requires a Base Station Interface Unit (BSU). The BSU 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 the Base Station also provides local radio coverage via a macro antenna, then a RF tap is required to extract a small amount of signal to drive the FTU. 6 3434 Rt. 22W, Suite 140 Branchburg, New Jersey 08876 (908) 253.9080

In an off-air scenario, the Headend Repeater Unit (HRU) provides the additional functions for an outdoor antenna port, 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 Fiber-Span s Headend Channelized BDA. This unit uses advanced Digital Signal Processing to distortion free filtering 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-of-band 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). Pictured on the product page is our core FTU, a 1U subrack which is capable of connection to four Remote Repeater Units (RRU). Depending on the size of the system, other larger-scale RRUs are available that provide WDM, CWDM and DWDM capabilities, as well as add/drop optical multiplexers and monitoring and switching for redundant configurations. Systems can be configured to operate uplink/ downlink on separate fibers, split RF bands onto their own fibers, split agencies onto their own fibers or all signals, uplink and downlink onto a single fiber strand. The configuration will be determined by the fiber available and the owners preferences. The FTU is where other signals. Such as Ethernet backbones, are optically added and dropped. Fiber-Span can even ride on existing lit fiber that supports other signals (Ethernet, video, data, DWDM, CWDM) so as to best utilize available resources. 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 (as shown in the illustration) may be required to manage the signal flow and optimize system performance. At the end of the fiber link the RRU converts the optical signal to RF, and internal filters and splitter/combiner, switch (as required) network manages it to the RF signal conditioning stages. 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. In every case, Fiber-Span can engineer a coverage extension solution for any space your clients or users may have. We have done so for others over twenty years.

Products System Building Blocks The essential building blocks of a fiber-based Public Safety Distributed Antenna System are described below. 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. HRU: Headend Repeater Unit Fiber-Span s equivalent to the BDA. The HRU is the interface to the donor antenna and is located at the Headend of any in-building off-air 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. 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. 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. 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. 8 3434 Rt. 22W, Suite 140 Branchburg, New Jersey 08876 (908) 253.9080
