3 Interfaces Overview
This chapter provides an overview of the W3x interfaces.
3.1 UMTS/GSM Radio Interfaces
The W3x terminals support UMTS and GSM/GPRS/EDGE radio interfaces
where UMTS is the primary interface.
3.1.1 UMTS
The W3x terminals support UMTS 850/1900 MHz and 2100 MHz frequency
bands.
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 W3x terminals support 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 W3x terminals peak download speed is rated up to 7.2 Mbps and the
peak up-link speed is 2.0 Mbps, software upgradeable to 5,76.
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 W3x
series radio configuration according to simulations in urban and suburban
environments.
