1 General
Description
This specification provides general information regarding performance and integration of W2SW0011U,
a complete wireless subsystem featuring 802.11 b/g/n 2.4Ghz WLAN capabilities in a small form factor
module. The W2SW0011U device is designed to simplify the process of adding wireless capability
without lengthy design cycles or complex RF design. It is completely tested for functionality and
performance along with coexistence with other wireless standards. A full menu of certifications will also
be provided, simplifying the certification process for your end product while further reducing valuable
time-to-market. Based on world-class silicon from Marvell, the W2SW0011U has been fully optimized
for throughput and receive sensitivity using careful design practices. Software development resources
are available to create drivers for unique processors and operating systems if needed, and to optimize the
wireless subsystem for your application.
The specification maximum and minimum limits presented herein are those guaranteed when the unit is
integrated into the Wi2Wi’s W2SW0011U-DEV Development System. These limits are to serve as
representative performance characteristics of the W2SW0011U when properly designed into a
customer’s product. Wi2Wi makes no warranty, implied or otherwise specified, with respect to design
and performance characteristics presented in this specification when used in customer designs.
The latest revision of this document supersedes all previous versions of this document. Wi2Wi reserves
the right to change this specification without notice.
2 Features
• Compact design for easy integration: 15mm x 15mm
• LGA with 60 pins
• WLAN technology based on Marvell’s 88W8786
• Certified radio
• Optimized RF and electrical design for better performance in co-existence with other wireless
standards
• Operates in 2.4GHz ISM band
• ROHS Compliant
• Single supply of 3.3V
• Integrated coexistence support for Bluetooth
• USB 2.0 HS (480Mbps)
• 50-Ohm antenna launch
• Support for various operating systems
• 1, 2, 5.5 and 11 Mbps data rates for 802.11b (DSSS/CCK modulation)
• 6, 9, 12, 18, 24, 36, 48 and 54 Mbps data rates for 802.11g (OFDM modulation)
• 50 Mbps, 72Mbps for 802.11n, planned support for 150 Mbs in a later revision
