EMS Wireless EkoLite II Operator’s Manual 1.0 Introduction The system overview describes the need for distributed RF antenna systems in general terms and the concept of a fiber optic repeater system. The functional overview describes the EkoLite II system as it is broken down into its major components. 1.1 System Overview The EkoLite II System is designed to distribute Cellular and PCS radio signals within a building or campus of buildings where coverage/capacity would be otherwise impeded.
EMS Wireless EkoLite II Operator’s Manual EkoLite II system would be a multi-floor building such as the one depicted in Figure 1. In buildings of this type it is common to find equipment rooms for Heating, Ventilation and Air-Conditioning (HVAC) and other utilities such as data networking and telephony equipment. There are numerous advantages to centrally located utilities and services and cellular equipment is no exception.
EMS Wireless EkoLite II Operator’s Manual 1.2 Functional Overview There are four main components comprising the EkoLite II System: The Hub, the Remote, the Fiber, and the Antenna. Figure 2 is a functional diagram of the EkoLite II system. 1.2.1 Hub The Hub interfaces directly to the service provider’s BTS and is typically located in the equipment or utility room in most installations.
EMS Wireless EkoLite II Operator’s Manual Each EkoLite II Hub can support up to eight Remotes. If more than eight Remotes are required, up to 3 additional Hubs can be added allowing for a total of 32 Remotes. 1.2.2 Fiber EMS recommends single mode 9/125 µm optical fiber for use in the EkoLite II system. It is also recommended that a high quality SC/APC connector be used to minimize reflections at the mating ends of the fiber. SC/APC connectors are standard on both the Remote and the Hub.
EMS Wireless EkoLite II Operator’s Manual Figure 4. EkoLite II Remote The standard EkoLite Remote has a self-contained antenna. Optionally, an SMA(f) connector may be specified so an external antenna may be used. In this case, the internal antenna is not installed at the factory. Also, internal 1:2 or 1:4 power splitters may be specified and factory installed inside the remote unit so multiple antennas can be used. The outputs from these splitters are SMA(f) connectors on the back of the remote unit. 1.
