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.

1.4 Ericsson W2x Feature Summary
The main features of the Ericsson W2x terminals are:
• Multimode broadband WAN connectivity
WCDMA/HSDPA (850/1900/2100 MHz) as primary access and
GSM/GPRS/EDGE (850/900/1800/1900 MHz) as fall-back. Peak
download data rates 1.8 Mbps for Ericsson W20 and 3.6 Mbps for
the Ericsson W21/W25. (The Ericsson W21/W25 is software
upgradeable to 7.2 Mbps).
• Four ports Ethernet switch;
Routing, NAT, ALG, DHCP and DNS Server.
• Two USB 2.0 ports;
File and printer sharing.

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):
Category
(HS-DSCH)
Peak data rate
(Mbps)
No of codes
(HS-DSCH)
Modulation
(16QAM/QPSK)
Category 1 1.2 5 Both
Category 2 1.2 5 Both
Category 3 1.8 5 Both
Category 4 1.8 5 Both
Category 5 3.6 5 Both
Category 6 3.6 5 Both
Category 7 7.2 10 Both
Category 8 7.2 10 Both
Category 9 10.7 15 Both
Category 10 14.4 15 Both
Category 11 0.9 5 QPSK
Category 12 1.8 5 QPSK
However peak upload speeds are only possibly with normal usage in a cell
and with optimal signal conditions. Typical download speeds experienced
by the users with multiple concurrent voice and data users in the cell,
ranges from 0.6 Mbps to 1.1 Mbps on average with current W2x series
radio configuration according to simulations in urban and suburban
environments. This rate will eventually evolve up to 6-7 Mbps with future
radio configuration updates of the W2x series.
