1.1 The Features Britecell Plus is an innovative platform designed in order to provide an effective and flexible coverage to a large variety of indoor scenarios. Thanks to its high modularity, its low power consumption, and its full-transparency to protocols and modulation formats, Britecell Plus is the perfect plug&play solution to distribute any wireless standard (including GSM, GPRS, EDGE, CDMA, WCDMA, and WLAN IEEE 802.
1.3 Britecell Plus Features The following lines report a brief summary of Britecell Plus main features: • multiband 2G, 2.5G and 3G – 802.11b WLAN compatible: Britecell Plus is completely transparent to any transmission protocol and modulation format, and it can distribute any 2G, 2.5G, 3G wireless standard. In addition, a special option allows to carry also the WLAN (802.
1.4 Britecell Plus typical Applications Thanks to its unique features Britecell Plus is the ideal solution to set up radio coverage in may situations: • Multi operator shared infrastructure: each mobile operator has its own carriers, which must be transported without affecting the others.
Bureau(s), including antenna co-location requirements of 1.1307(b)(3). Maximum permissible antenna gain is: Britecell Plus TFAM Remotes: 10dBi. 1.6 Britecell Plus Operation with Multiple RF Channels The Manufacturer's rated output power of this equipment is for single carrier operation. For situations when multiple carrier signals are present, the rating would have to be reduced by 3.5 dB, especially where the output signal is re-radiated and can cause interference to adjacent band users.

2.1. The Remote Unit TFAxxx and relevant TKA installation kit The TFAxxx is a device providing optical-to-electrical downlink conversion and electrical-to-optical uplink conversion, thus allowing a bidirectional transmission of signals between one TFLN and the remote antennas. It is available in 3 versions (low-power, medium-power, and high-power), each designed in order to support different output power levels on RF antenna ports. Fig.
2.2. The Britecell Plus Master Unit Below are listed the Britecell Plus modules. For further details about these components, refer to the next chapters of this manual. The Sub-rack (TPRN) is a 19” subrack hosting the Britecell Plus modules; it accommodates 12 slots, whose sizes are 7 TE x 4 HE. As each Britecell Plus module takes up one or two slots, each Master Unit can sustain up to 12 modules, depending on design configuration and requirements.
TBSI: Width = 7TE, Height = 4HE, i.e. a 1-slot space TDI: Width =14TE, Height= 4HE, i.e. a 2-slot space The RF diplexer (TLDN): in downlink it combines a low band RF signal (800 to 1000 MHz) and a high band RF signal (1700 to 2500 MHz) into a common RF port; in uplink it splits a composite signal between a low band RF port and a high band RF port. Module dimensions: Width = 7 TE, Height = 4 HE (one slot).
In uplink TLCN2 (TLCN4) splits the composite RF signal coming from a LU into 2 (4) RF signals entering different BTSs. The WLAN interface board (TWLI):.it connects 3 WLAN Access Points to each TFLN, and it is necessary when 802.11b WLAN distribution through the DAS is required. Dimensions: Width = 14 TE, Height = 4HE (2 slots). The wideband amplifier (TWANxx): it is an amplifier used to interface low power base stations to Britecell system.
2.3. Block diagrams To better understand the functions of the different units and modules, two block diagrams of the Britecell Plus system are reported here. The first diagram (Fig. 4) refers to the case of duplexed BTSs, ie. BTS conveying both the downlink and uplink signals on a single RF port. In this case, a THYN module is required to combine the uplink and downlink paths on a single RF port. The second diagram (Fig.

Main processes carried out by the TFAxxx: Module name: Remote Unit TFAxxx Case A • In Downlink (DL) operations: Optical-to-RF conversion of the input optical signal Automatic Gain Control (AGC) of each converted signal, in order to compensate optical losses (provided they are < 4dB); RF amplification: the converted RF signal is boosted in order to maintain a good signal-to-noise ratio RF filtering: a proper filter rejects the spurious emissions which lie out of the Downlink band RF duplexing and splitting
Main processes carried out by the TFAxxx: Module name: Remote Unit TFAxxx Case B • In Downlink (DL) operations: Optical-to-RF conversion of the input optical signal Automatic Gain Control (AGC) of each converted signal, in order to compensate optical losses (provided they are < 4dB); RF amplification: the converted RF signal is boosted in order to maintain a good signal-to-noise ratio RF filtering: a proper filter rejects the spurious emissions which lie out of the Downlink band RF duplexing and splitting
Visual alarms: Two control LEDs are provided on the TFAxxx front side. The green LED describes the power supply status, while the red LED describes the major Remote Unit failures. TFAxxx LED Led colour Red Green Meaning Low optical power at DL input and/or RF amplifier failure Power supply status dry contacts Dry contact alarms: TFAxxx is provided with two dry contacts inputs, which can be connected (through .062” MOLEX plugs) to any external device (ie. the TFBW booster).
Case B Remote Unit and TFAN20 These Remote Units are provided with external power supply both for the 220VAC option and for the -48VDC option.
• Do not touch the connector tip. Clean it with a proper tissue before inserting each connector into the sleeve. In case connector tips need to be cleaned, use pure ethyl alcohol. WRONG OPTIMAL TFAxxx installation instructions The TFAxxx kit includes: A. 1 remote unit TFAxxx B. a 50 Ω load and according to the chosen model C. an external power supply adapter (85-264 Vac or -48 VDC) D.
