1. Preface
This document describes the operation of the wireless IP -based base station (WIBS) for CDMA
PCS and cellular systems. The WIBS provides the interface between CDMA PCS personal stations
(PS) or cellular mobile stations (MS) and a Wireless IP Server (WIS) and related IP entities. Getting
Started provides the brief functional description of the system. Specification presents detailed
performance, electrical, physical and reliability specification of the system. Start Up and Basic
Operation describes the basic operation procedure including installation. SCMenu presents the
advanced operation procedure and management for call processing and resource management.
Maintenance gives some information regarding management of WIBS system.
2. Safety
2.1 General Safety Summary
To keep the following safety direction is very important to operate WIBS system safely and to
prevent the system from damage and operator’s injury.
• Proper Power Source : The power requirements presented in this manual should be kept
very tightly.
• Temperature : Do not expose to extremely hot or cold environment.
The proper temperature range is –30 °C to 50 °C
• Explosive Atmosphere : Keep the system away from explosive material
• Installation : A qualified person should install the system to avoid some failure and
damage
• Failure : Stop the operation and contact customer service.
• Modification : Don’t modify any part of the WIBS system.
• Electric Shock : Careful treatment require to avoid the electrical shock.
i Warning for RF Exposure : In order to comply with FCC RF exposure limits, system should
be located at a minimum distance of 7.9 inches (20 cm) or more from the body of all person.

3. Getting Started
WIBS are used to provide innovative services for enhancing mobility in a wireless office
environment and covering hot spot or dead spot of traditional public cellular or PCS networks, such
as on campus, on the load, etc. WIBS is connected to the IP network through 10/100base-T
interface and related software stack (H.323, etc.), and can also be used for conventional PCS or
cellular systems. WIBS is a part of an IP -based wireless office system which includes WIBS, WIS,
IP-PBX, IP -Phones, etc.
4. SPECIFICATIONS
Some fundamental system requirements for WIBS are described in following sections.
4.1 Functional Specifications
4.1.1 Operating Frequency
The WIBS operates at frequencies specified in the following tables:
Unit (U.S. PCS) Frequency Range (MHz)
Transmit 1930 - 1990
Receive 1850 - 1910
Table 2.1.1-1 PCS Operating Frequency
Unit (DCS) Frequency Range (MHz)
Transmit 869 - 894
Receive 824 - 849
Table 2.1.1-2 DCS Operating Frequency
4.1.2 Interface Specification
4.1.2.1 Air Interface
The WIBS for a digital cellular system (DCS) shall comply with IS-95A (1st stage) and IS -95B (2nd
stage). The WIBS for a personal communication services (PCS) shall comply with ANSI J-STD-008.
4.1.2.2 Backhaul Interface
There is a 10/100base-T Ethernet interface between the WIBS and the IP -network. A T1 or E1 trunk
can be used for the interface between a WIBS and a conventional CDMA wireless network
(optional).

4.1.3 Operation and Maintenance
4.1.3.1 Operation/Configuration Management
The WIBS should manage the data related to operation and configuration of its subsystems:
Ÿ Program/data downloading
Ÿ Radio resource management
Ÿ Configuration data management
Ÿ CDMA parameter management
4.1.3.2 Performance Management
The WIBS should collect and analyze data related to system performance, and send them to the
higher level entity for management (WIS, etc):
Ÿ Call-related parameters and statistics
Ÿ CDMA radio performance related parameters and statistics
4.1.3.3 Maintenance Management
The WIBS should perform detection, report, and recovery of abnormal operation:
Ÿ Fault detection and management
Ÿ Alarm monitoring and processing
Ÿ Periodic test for maintenance/diagnosis
Ÿ Status management
4.1.4 Configuration Features
Ÿ One WIBS supports one FA, one sector or one unidirectional cell.
Ÿ It can be operated with several kinds of RF front-end systems, such as in-building
repeaters, optical repeaters, distributed antennas, remote RF units, etc.
Ÿ A multi-sector cell site can be configured with multi-WIBSs where only soft handoff is
allowed between WIBSs, but softer handoff is not. For a conventional wireless network,
multiple WIBSs can be daisy-chained with one T1/E1 trunk to BSC (optional).
Ÿ Each channel element may be configured to one of following personalities :
◊ A pilot channel and a sync channel
◊ An access channel
◊ A paging channel
◊ A traffic channel
