3. Introduction
The WU260 is a Draft IEEE802.11n-compatible USB module in a 2x2 MIMO configuration and operating in the 2.4 and
5GHz ISM band. This module allows an embedded host to use its USB 1.1 or 2.0 interface to connect to a Draft
IEEE802.11n compatible access point at unprecedented speeds.
The WU260 USB module is based on Broadcom’s BCM4323 65nm chipset. It provides greater than 100Mbps real world
throughput using high-speed spatial multiplexing modes. Configuration and testing of this module must be done on the host via
Broadcom provided software tools..
4. Features

• Backward compatible with USB v1.1.
• Draft IEEE 802.11n version 2.0 compatible.
• Backward compatible with IEEE 802.11b/g standards.
• Wire-free access to networked resources from anywhere beyond the TV.
• Delivers data rate up to 300 Mbps.
• 802.11n: Dynamically shifts among 130, 117, 104, 78, 52, 39, 26 and 13Mbps in a 20MHz bandwidth and 270, 243,
216, 162, 108, 81, 54 and 27Mbps in a 40MHz bandwidth, based on signal strength, for maximum availability and
reliability of connection.
• 802.11a/g: Dynamically shifts among 54, 48, 36, 24, 18, 12, 9 and 6 Mbps network speed, based on signal strength,
for maximum availability and reliability of connection.
• 802.11b: Dynamically shifts among 11M, 5.5M, 2M, and 1 Mbps network speed, based on signal strength, for
maximum availability and reliability of connection.
• Uses 2.4 and 5GHz frequency band, which complies with worldwide non-license bands.
