Chapter 1

Introducing Vanu Anywave BSS

1.1 Introduction

Welcome to the Vanu Anywave Base Station System Operator Guide. This manual is designed to serve
as an information resource for the Vanu system you will be deploying. This guide focuses on hardware
preparation and deployment, and prepares you to provide first line technical support for the Anywave
BSS.

1

1.2 Operator Guide Scope and Objectives

This Guide will cover the following topics:

• Anywave Components and Connections

• System Operation

1.3 Operator Guide Assumptions

This Operator Guide assumes that the audience will have working knowledge about the following topics:

• Basic commands and usage of a Linux (or Unix) server, such as: user configuration, logging in,
copying files, up- and down-loading files, file permissions, file editing, etc.

• This BSS Operator Guide concentrates primarily on setup of the system; it is not intended to act as
an exhaustive guide on how to troubleshoot network issues or specific calls.

1.4 Benefits of the Vanu Anywave BSS

The Vanu Anywave base station provides Radio Access Network (RAN) functionality by implementing a
complete GSM Base Station Subsystem (BSS) in software on a single general-purpose server. Signal
processing, protocol processing, and other radio access network functionality are implemented as
application level software running on top of the Debian GNU/Linux operating system.

Features

The Vanu Base Station System (BSS) has four major software components:

• The Base Transceiver Station (BTS) handles communication over the air interface with individual
mobiles. A BTS can handle many radio links simultaneously, and is responsible for any ciphering
over the air interface.

• The Base Station Controller (BSC) acts to manage a number of BTSs on functions such as radio
resource allocation, mobile handover, and passing messages to the mobile from the core network.

• The Transcoder and Rate Adapter Unit (TRAU) performs transcoding for speech channels and rate
adaptation for data channels, as necessary.

• The Packet Control Unit (PCU) is only found in a GPRS (General Packet Radio Service) network.
The PCU handles the radio resource aspects of GPRS connections.

Working together, these components integrate into a complete BSS solution that provides the full
functionality of a GSM Radio Access Network (RAN).

The Vanu Anywave System seamlessly connects mobiles to the phone network by first making a
mobile-to-BTS connection via the radio (or “air”) interface. The BTS is connected to, and exchanges
data with, the BSC via the Abis interface. The BSC then communicates to the MSC via the A interface.

In the data domain, there is a similar Gbis interface between the BTS and PCU, and a Gb interface
between the PCU and SGSN (Serving GPRS Support Node) for GPRS data.

A full base station is composed of the following major subsystems:

• An RF Front End, supporting the 850, 900, 1800, or 1900 MHz bands, which perform
Analog-to-Digital and Digital-to-Analog conversions, as well as up/down mixing and duplex
functionality.

• Waveform processing performed by the Anywave BTS software on a standard commercial server.

• A GPS timing reference.

• A typical BTS installation has other important parts that are not considered Vanu Anywave

components, such as: antenna(s), amplifier(s), power conditioning, and others.

1.5 Network Operator Role

As Network Operator, you will oversee project planning and deployment of all components for the
wireless infrastructure, including the Vanu Anywave BSS. This process will require working with Vanu,
Inc. Technical Support to ensure all required settings are appropriately determined, implemented and
documented.

The following is an overview of the Network Operator Role and some of the duties you will be expected
to perform:

Deployment

• Understand the purpose of all hardware components used in the BSS

• Connect the hardware components of your BSS system

• Install and configure the various software applications used by the system

Operation

• Provide first line customer support in the pursuit of issue resolution, and ensure effective data
transfer to Vanu, Inc. Technical Support for all support escalations, as determined by existing
service level agreements.

• Manage technical issues regarding hardware and software required to run the Vanu Anywave
system.

• Coordinate and confirm system downtime with Vanu, Inc. Technical Support for the deployment of
system patches or general updates in accordance with service level agreements.
