1 W2x Series Overview

1.1 Introduction

The Ericsson Fixed Wireless Terminal (FWT) W2x product series is the base for Ericsson WCDMA/HSDPA FWTs. The W2x product series is based on a platform concept aiming at providing a set of differentiated terminals from well-defined technical platforms.

The W2x product series consist of different types of terminals. Currently there are three terminals in the W2x product series:

• Ericsson W20 – Data Terminal

- W20a for 850/1900 MHz frequency bands

- W20e for 2100 MHz frequency bands

• Ericsson W21 – Data Terminal

• Ericsson W25 – Data and Voice Terminal

With WCDMA/HSDPA WAN radio access capability the W2x products are well suited to provide broadband data access with data speeds similar to fixed line DSL services.

1.2 Ericsson W20/W21 - Data Terminal

The Ericsson W20/W21 provide data capabilities such as data access (e.g. Internet) in the respect that it allows multiple computers to be connected to the terminal using Ethernet or wireless LAN (WLAN).

1.3 Ericsson W25 – Data and Voice Terminal

The Ericsson W25 data and voice terminal incorporates the same set of data features as the Ericsson W20/W21. Additionally, this model also includes voice and fax capabilities over standard analog telephone interfaces. A broad range of network services such as Prepaid Subscription, CLI (Calling Line Identification), Call Waiting, Call Barring, Call Forwarding, Multiparty Conference Calls are supported. WCDMS/HSDPA radio access is well suited for combined and efficient data and voice transmission over the mobile network.

2 Hardware Architecture

2.1 Power Supply

The W2x terminals can be powered from:

• AC Mains via an external AC/DC power adapter (10-28 VDC)

• Battery backup (Ericsson W25).

2.1.1 Power Adapter

The provided power adapter has the following characteristics:

Input: 100-240V AC, 50-60 Hz, 3 pole AC inlet connector (IEC 320 power inlet). Output: 12 VDC. Power consumption: 7.0 W (typical) and 11.4 W (maximum) for Ericsson W20/21 and 9.0 W (typical) and 16.2 W (maximum) for Ericsson W25.

National power plugs are available for EU, UK, US and AU.

2.1.2 Battery Backup (W25 only)

The Ericsson W25 can be fitted with a rechargeable battery to provide redundancy in case of an AC Mains power failure. The battery is available as an accessory and is facilitated within the unit. Additionally there is an internal battery charger that can recharge the battery.

2.2 UMTS/GSM Radio Interfaces

The W2x terminals support UMTS and GSM/GPRS/EDGE radio interfaces where UMTS is the primary interface.

2.2.1 UMTS

The W2x terminals support UMTS 850/1900 MHz and 2100 MHz frequency bands.

The UMTS interface supports the following characteristics:

• WCDMA

• HSDPA Category 11 and 12 (W20)

• HSDPA Category 1-6 and 11 (W21/W25)

The Ericsson W21/W25 is software upgradeable to 7.2 Mbps which means support for HSDPA Category 7 and 8.

2.2.2 GPRS/EDGE

The W2x terminals support GSM/GPRS/EDGE 850/900/1800/1900 MHz frequency bands.

2.2.3 HSDPA Throughput Rates

The peak download speed is rated up to 1.8 Mbps for the Ericsson W20 and 3.6 Mbps for the Ericsson W21 and Ericsson W25. The peak up-link speed is 384 kbps. The rated HSDPA peak download speeds will eventually evolve up to 14.4 Mbps with enhanced radio performance (increased modulation and coding schemes) according to the table below (current W2x rated peak speeds highlighted):
