Dual-Band 802.11n Wi-Fi Module for
IoT Applications
New Module Features Industrial Temperature, Premium Enterprise Reliability
The SX-ULPAN is an ultra-low-power, dual-band 802.11 a/b/g/n
Wi-Fi module with industrial temperature support. This module
provides the reliable connectivity for various microcontroller-based
networking applications that your customers need.
Founded on world-class expertise from Silex Technology, and
powered by the Qualcomm Atheros 4004 intelligent networking
platform, the new solder-down module connects your device to
the Internet of Things and provides a reliable connectivity experience for your customers.
The module’s small form factor, rich features, and ultra-low power
make it perfect for many mobile wireless applications and portable
battery-operated devices.
Typical Applications: SX-ULPAN will find its way into many IoT
applications like remote equipment monitoring, asset tracking and
telemetry, security, wireless audio, industrial sensors and controls,
home automation, medical devices, and many more.
Key Features:
Single Stream System (1x1) and 20MHz channel width.
On-Board U.FL connector and on-board antenna
surface mount module
• Data
MCS 0-6 for 802.11n, 1 -54 Mbps for 802.11b/g and 6 -54 Mbps for
802.11a. Due to the limitiations of the SPI host interface the actual
throughput is limited to 10 Mbps .
• Roaming
Roaming supports the client moving between different access
points in a seamless manner.
Protected Setup
• Wi-Fi
WPS 2.0 implementation makes it easy to add new devices to an
existing network without entering long passphrases.
TCP, and UDP protocol supported on chip
• IPv4,
It helps offload the host microcontroller. Functions supported
are ARP, iPv4, UDP, TCP socket support, DHCPv4, neighbor
discovery, broadcast, MTU discovery, address auto config, and
TCP zero copy.
