Quatech APMG-Q551 Specifications

AirborneTMWireless Access Point Module

802.11b/g Wireless AP

APMG-Q551

Flexible & Easy to Integrate

Airborne incorporates support for both
serial to Wi-Fi and Ethernet to Wi-Fi
communications. Utilizing Airborne's
PortFlex capability, OEMs may configure
via software any combination of UART,
SPI, Ethernet, GPIO and 802.11
interfaces. Each individual port can be
independently configured.

The Airborne line of highly-integrated

802.11 wireless modules allow OEMs
to Wi-Fi enable devices used in an array
of machine-to-machine (M2M)
applications. By providing all of the
necessary RF technology, networking
stacks and advanced security features
in a compact, single-board package, the
embedded Airborne Model APMG-Q551
module allows OEM customers to
incorporate AirborneAP™ technology into
their 802.11 wireless design solutions.

Big Performance in Small and
Ruggedized Package

The APMG-Q551 access point module
delivers the industry's most rugged,
highly-integrated, embedded Wi-Fi
access point solution. Airborne modules
meet extended operating temperature
and shock/vibration specifications of the
most demanding M2M applications.

Utilizing a 32bit ARM9 processor and
the high-performance Atheros AR6002

802.11 radio, the new Airborne modules
deliver increased transmit power
and receive sensitivity, contributing
to superior range performance.

The new Airborne SpeedLink roaming
feature provides enhanced connection
reliability, enabling OEM devices to roam
freely within a wireless network without
loss of data or connection.

Airborne PowerSave firmware enables
OEMs to maximize efficiency and reduce
power consumption by as much as 70%.
PowerSave capability is especially critical
for battery-powered mobile devices.

OEMs can choose to incorporate both
transmit and receive diversity capability
in their designs by utilizing the two U.FL
antenna connectors on the modules.

The APMG-Q551 modules are
footprint and pin-compatible with their
predecessors, dating back to the original
introduction of the Airborne product
family. Quatech's commitment to
maintaining hardware and software
compatibility assures OEMs of a simple,
future-proof migration path even as
wireless technology evolves.

Enterprise Class Security

Quatech's multi-layered security
approach addresses the requirements of
Enterprise-class networks and corporate
IT departments. These advanced
security features include wireless security
(802.11i/ WPA2 Enterprise); network
security (EAP authentication and
certificate support); built-in firewalls
on the Ethernet and WLAN interfaces;
secure communications (built-in SSH
functionality and fully encrypted data
tunnels for secure management and data
transfer); and device security (multi-level
encryption capability to protect sensitive
device configuration data). EAP security
protocols are supported on the
AirborneAP™ Access Point in client
mode only.

A unique Airborne security feature is
the onboard delivery of certificates
to the module and management of all
authentication processes without
requiring interaction from the host. This
substantially reduces the resource
requirements for OEMs whose devices
operate in Enterprise-Class wireless.
