Anywave BSS Operator Guide Preface The Anywave® Base Station Subsystem (BSS) Operator Guide is intended for system users who have completed the Vanu Anywave System Training Course. This Anywave BSS Operator Guide provides an overview of the Vanu Anywave Base Station Subsystem application structure, along with information on how to perform system tasks, general system maintenance, and basic issue resolution procedures.
CHAPTER 1. Introducing the Vanu Anywave BSS Introduction Welcome to the Vanu Anywave Base Station Subsystem Operator Guide. This manual is designed to serve as a knowledge resource for the Vanu system currently installed at your site, and to assist you in your role as System Operator. This guide focuses on ongoing system maintenance, and prepares you to provide first line technical support for your Anywave BSS.
Anywave BSS Operator Guide What makes Vanu Anywave BSS different? The Vanu Anywave GSM BSS provides radio access network functionality by implementing the BTS (Base Transceiver Station) in software running on a general-purpose server. Signal processing, protocol processing, and all other radio access network functionality are implemented as application level software running on top of a Debian GNU/Linux system. The Anywave BTS system uses Protium wideband RF front ends from Protium Technologies.

Anywave BSS Operator Guide System Operator Role As System Operator, you will maintain and support all components of the Vanu Anywave wireless infrastructure. By the time you receive this document, you will already have met several important milestones. You will have worked with Vanu, Inc.’s Deployment group to plan and deploy your current installation, and you will have attended the Vanu, Inc. System Operator Training Course.
CHAPTER 2. BTS Components & Connections The BTS provides the air interface in a particular region, also known as a cell, to each Mobile Station (cell phone) located within its border with an active connection.
Anywave BSS Operator Guide BTS Server The Anywave BTS software application is hosted on an Intel TIGI2U NEBS server running a Debian GNU/Linux operating system. The RF data enters the server from the Protium RF front end units through an Ethernet connection. GSM audio signaling is routed internally from mobile to mobile using the Anywave Micro-MSC. An Ethernet port connects the BTS server to the Ethernet switch.

RF Front End The wideband RF front ends perform transmission and reception over the air interface between the BTS and a number of GSM mobiles. Using a wideband multi-channel front end allows one BTS unit to transmit and receive multiple carriers over a wide frequency band of up to 25 MHz. The RF front ends include both the RF up/down converters and the digital IF subsystem, which perform digital filtering, timestamp injection and other functions.
Anywave BSS Operator Guide Overview of Protium RF Front End Connections The RF signal is received through the Main Antenna port, located on the Duplexer panel. RF data received from the Main Antenna is run through the Duplexer, out the Main RX SMA port, then over a cable to the Main RX SMA on the Up/Down Converter panel. This signal is then converted to digitized data and sent out through an Ethernet port to the server.

Protium 850 Indicator LEDs The front of the Protium unit has two LED lights, which serve both compartments of the RF Front End unit. The green LED indicates that power is active on the unit. The red LED indicates that an alarm in the system has been triggered.
Anywave BSS Operator Guide Power Shelf The Powerwave Power Shelf converts 120 V AC current to 28 v DC current. The capacity to hold up to three power modules makes it easy to swap out an existing power module if necessary, or to increase DC power. The Power Shelf used in your deployment will have two power modules, with a total of 8 connections (4 red, 4 black) to the Powerwave MCPA. Each power modules will have its own 120 V power source.
Power Amplifier The Powerwave Amplifier is used as the Power Amplifier for each RF Front End in the network. The output from the RF Front End is sent to the PA via a Coax cable and is then amplified by 63 dB. You will have four Power Amplifiers in your deployment. Only the two PAs in use should be powered on. The two PAs not in use should be shut off using the On/Off Reset Switch located on the front of each PA.

Anywave BSS Operator Guide GPS Timing Source The Brandywine GPS 4 Timing Source simply provides a 10 MHz and 1 Hz clock signal to the Protium for precision timing. The Timing Source provides a reference clock to the RF equipment for timestamping. Timestamps are used to ensure the correct alignment of data throughout the system. The serial port connection from the GPS Timing Source to the BTS server is used for configuration and diagnostic purposes.
GPS 4 Timing Source Indicator LEDs Figure 13: GPS 4 Timing Source Indicator LEDs Power: Indicates that the unit is powered on. Locked: The Protium unit is synched with the GPS. Holdover: There is a valid clock, but it is not synchronized with the GPS. Alarm: The GPS unit is not functioning properly. Please Note: The “Power” LED should be lit when the unit is powered on.
Anywave BSS Operator Guide CHAPTER 3. Base Station Operation Hardware Once all the hardware is connected, the system can be launched. Turn on the power for each of the hardware components. The power buttons or switches are located on the front of the TIGI2U server, below, and on the back of the Protium (see Figure 7, page 12) and GPS timing source unit (see Figure 12, page 19).
