3 Interfaces Overview
This chapter provides an overview of the interfaces on the Ericsson W3x.
3.1 UMTS/GSM Radio Interfaces
The Ericsson W3x supports UMTS and GSM/GPRS/EDGE radio interfaces
where UMTS is the primary interface.
3.1.1 UMTS
The Ericsson W3x supports UMTS 850/900/1900/2100 MHz frequency
bands.
Product variants is available supporting different frequency band
combinations (850/1900/2100 MHz and 900/1900/2100 MHz).
The UMTS interface supports the following characteristics:
• WCDMA
• HSPA, Category 1-8 and 11/12, up to 7.2 Mbps (downlink) and
Category 3 and 5, up to 2.0 Mbps (uplink)
3.1.2 GSM/GPRS/EDGE
The Ericsson W3x supports GSM/GPRS/EDGE 850/900/1800/1900 MHz
frequency bands.
The GPRS/EDGE interface supports the following characteristics:
• GPRS, multi-slot class 12 CS 1-4
• EDGE, multi-slot class 12, MCS 1-9
• Dual Transfer Mode (DTM)
3.1.3 HSPA Throughput Rates
The Ericsson W3x peak download speed is rated up to 7.2 Mbps and the
peak up-link speed is 2.0 Mbps. Future releases will support uplink speed
up to 5.6 Mbps.
However peak downlink speeds are only possible 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 5.0 Mbps on average with current
Ericsson W3x radio configuration according to simulations in urban and
suburban environments.
