Scope

This document describes key hardware aspects of the Summit WB40N wireless bridge module. This document is

intended to assist device manufacturers and related parties with the integration of this module into their host devices.

Data in this document are drawn from a number of sources including data sheets for the Broadcom BCM4329 and

Atmel AT91SAM9G20.

Because the SDC-WB40NBT is currently in pre-production, this document is preliminary and the information in this

document is subject to change. Please contact Summit or visit the Summit website at www.summitdata.com to obtain

Product Description

This device is an SDC-WB40NBT Wireless Bridge Module, a wireless

communications subsystem that may be integrated into a variety of host devices via

a number of available electronic and logical interfaces. The SDC-WB40NBT

provides complete enterprise-class Wi-Fi connectivity with an integrated TCP/IP

stack, full support for IEEE 802.11a/b/g/n air standards and a fully integrated

security supplicant providing 802.11i/WPA2 Enterprise authentication and data

encryption.

The SDC-WB40NBT has a wide variety of interfaces including Fast Ethernet, serial

UART, USB, SPI and I2C. The wireless bridge may be configured, monitored and

managed via a Command Line Interface over an available dedicated console port,

via a web interface over a wireless or Ethernet interface, or via a remote SDK

interface over wireless or Ethernet.

The SDC-WB40NBT incorporates the Summit SDC-SSD40NBT radio module and

provides all the Wi-Fi capabilities of that device. The product features an ARM9

processor running at 396 MHz, 32 MB of SDRAM memory, and 64 MB of NAND

flash storage. Several GPIO lines are available for data acquisition and similar

applications. The platform runs an embedded Linux operating system based on the

2.6 kernel. A Software Developer’s Kit with Application Programming Interfaces and

software tools are available for the development of custom software applications on the device.

The SDC-WB40NBT measures 47mm long by 37 mm wide by 3 mm tall. The width can be reduced to 30 mm by

removing a breakout section that is provided for configuration and test purposes. The wireless bridge physically

interfaces to the host device via a 120 pin board to board connector that has a variety of mating options. The SDC-

WB40NBT may be secured to the host device via available grounded mounting holes. The SDC-WB40NBT operates

at temperatures between -TBD and + TDB degrees Celsius.

Contingent on Compliance results… SDC-WB40NBT is a fully integrated module: It has its own RF shielding and

does not require shielding provided by the host device into which it is installed in order to maintain compliance with

applicable regulatory standards. As such, the device may be tested in a standalone configuration via an extender card.

The SDC-WB40NBTprovides two unique U.FL type antenna connectors to support dual band transmit and receive

diversity. Supported host device antenna types include dipole and monopole antennas.

Regulatory operational requirements are included with this document and may be incorporated into the operating

manual of any device into which the SDC-WB40NBT is installed. The SDC-WB40NBT is designed for installation into
