1.0 GENERAL INFORMATION 1.1 Functional Overview The VCom BTR5857 is a low cost 5.7 to 5.8 GHz Base Station Outdoor Unit (ODU) for use with VCom TRI5758 in broadband fixed wireless systems. The BTR5857 cost and performance makes it ideal for both point-to-point and point-to-multipoint systems. The BTR5857 combines a low noise downconverter, high power upconverter and high TM TM rejection duplexer to offer a quick and easy to install base station ODU for BWIN BASED ON DOCSIS . 1.
1.3 Specifications 1.3.1 BTR5857 Base Station Tranceiver Specifications TRANSMIT SPECIFICATIONS IF Input Frequency Bandwidth RF Output Frequency Range 516-540 MHz one or more RF carriers (4 x 6 MHz) 5775-5799 MHz (Low Band Option) 5799-5823 MHz (High Band Option) ± 0.3 dB +15 dBm (64QAM); +20 dBm (QPSK) Compliant with ETSI EN 301 021 v1.5.1, section 5.3.
2.0 INSTALLATION 2.1 Unpacking the Unit Carefully remove the equipment from its packing material and set it on a solid surface, such as a table or desk. If it appears damaged in any way, notify the carrier, and keep all packing materials for inspection by the carrier’s agent. 2.2 Mounting the Unit 2.2.
DIAGRAM 2.2A: LL-BRACKET ORIENTATION Once the L-bracket is in place, the unit can be mounted to the pole. The pole catch, V-bolt and L-bracket are oriented as shown in Diagram 2.2B. VCom Inc. BTR5857 Manual; ML_BTR5857_02 (Mar 2004) Approved: G.C.
DIAGRAM 2.2B: BTR5857 MOUNTED TO POLE VCom Inc. BTR5857 Manual; ML_BTR5857_02 (Mar 2004) Approved: G.C.
STEP 2 – Position V-bolt and pole catch around pole To attach the BTR5857 to the pole, first position the pole catch over the threads of the V-bolt and hold against the pole with one hand. VCom Inc. BTR5857 Manual; ML_BTR5857_02 (Mar 2004) Approved: G.C.
STEP 3 – Position BTR5857 against pole Using the other hand, bring the BTR5857 up to the pole catch and grab V-bolt, pole catch and L-bracket in a single hand. Ensure that the pole is inside the “L” of the L-bracket and not on the outside of the L. This is necessary to ensure stability during high winds. STEP 4 – Tighten BTR5857 against pole Tighten both ¼” locknuts against the L-bracket so that the unit is held against the pole but can still be rotated and tilted up and down for antenna alignment.
2.3 Connection to the Antenna and Power Inserter Connections to the BTR5857 are made as shown in Figures 2.3A, 2.4A Please note: 1) Connect the BTR5857 to the Antenna via the N-Connector. 2) Connect the BTR5857 to the CMTS via the F-Connector. Note that the BTR5857 is actually connected to the Power Inserter. The Power Inserter is then connected to the CMTS. 3) Cover all outdoor connections to the BTR5857 using self-amalgamating tape to prevent moisture from penetrating the connections. DIAGRAM 2.
2.4 Connection to CMTS, Power Inserter and Wall Adapter Connections to the BTR5857 are made as shown in Diagrams 2.3A and 2.4A Please note: 1) Connect the BTR5857 F-Connector to the power inserter, located indoors with the CMTS. The power inserter is then connected to the CMTS.
2.4 Waterproofing Connections Many transceiver problems can be attributed to environmental conditions (including vibration), which can loosen cables and permit moisture to penetrate the connectors. It is highly recommended that the connectors be sealed using a technique similar to the one described below. This will provide moisture protection and keep the connections tight.
When done, the connection should be tightly wrapped with tape, with a good seal to the cable. VCom Inc. BTR5857 Manual; ML_BTR5857_02 (Mar 2004) Approved: G.C.
