RealNet Solutions is offering a full-featured 802.11a/b/g
software framework to speed the development of innovative Access
Point (AP), home gateway, and bridge solutions for OEMs addressing
the consumer or corporate WLAN markets. Our Real-AP/Bridge platform
is fully compatible with the Atheros AR500x chipset family and provides
all the software components necessary to implement a variety of
Linux based WLAN devices, including the network protocol stack,
wireless chipset driver, and a comprehensive set of management tools.
Real-AP/Bridge is completely written in C language, therefore porting,
customization, and integration with the device maker’s embedded
designs can be accomplished very efficiently. Highly flexible and
scalable, individual features and modules can be removed or added
to tailor the software to the unique requirements of the target
application.

Product Benefits
|
|
Equipment vendors, OEMs, ODMs, and WISPs can benefit
from our Real-AP/Bridge framework in several ways:
|
|
| > |
Turnkey solution dramatically reduces development cost, risk,
and time to market |
|
|
| > |
Modular architecture, multi-device and multi-platform support
to address a broad range of target devices and applications |
|
|
| > |
Advanced wireless networking, QoS, and security features offering
a high degree of product differentiation |
|
|
| > |
Extensively tested and used by leading OEMs, Real-AP/Bridge
provides a proven foundation for highly reliable and interoperable
product designs |
|
|
Versatile Building
Blocks
|
|
Besides powering conventional full-featured wireless
APs or routers, Real-AP/Bridge can also serve as the software platform
for lightweight APs that are used in combination with wireless switches.
Furthermore, Real-AP/Bridge enabled devices can be configured to
operate in AP Client or Wireless Repeater mode, or to construct
Wireless Distribution Systems (WDS) comprising a Root AP (base station)
and one or multiple WDS Client APs (subscriber units). The Root
AP and WDS Client AP utilize the four-address scheme defined in
the IEEE 802.11 specification to send and receive wireless frames
across the point-to-multipoint or point-to-point bridge link. The
Root AP can serve WDS Client APs and legacy WLAN stations, enabling
both fixed and mobile wireless communications.

Enabling Device Makers
to Tap New Markets: Metro Wi-Fi and Public Safety
|
|
| Unlike other implementations, the Real-AP/Bridge platform
also allows the creation of self-healing and self-configuring mesh
networking architectures. Mesh topologies are ideally suited for the
delivery of wireless network services to locations where backhaul
cabling is costly or impractical. Every mesh-enabled AP serves as
a relay point for its adjacent peers, automatically extending the
range and robustness of the wireless network. The Real-AP/Bridge suite
includes a proprietary link layer protocol to calculate the best communication
path, and makes use of protocols such as CDP and LLDP for automatic
discovery of mesh exit points. Our dual-radio capabilities maximize
performance by allowing concurrent wireless backhaul and station access
services, and include support for the 4.9 GHz band designated by the
FCC for public safety use. |

Optimized for VoIP
and Consumer Electronics Devices
|
|
| Beyond enabling data-centric applications, our Real-AP/Bridge
framework has been specifically designed to meet the demands of developers
who require integrated Quality of Service (QoS) for their digital
media designs, facilitating the reliable transmission of time-sensitive
voice and video traffic. Real-AP/Bridge supports a subset of the draft
802.11e specification, the Enhanced Distributed Coordination Function
(EDCF), to provide prioritized media access within each device. Since
end-to-end QoS is required for the multimedia application to work
properly, Real-AP/Bridge provides the ability to map IETF DiffServ
tags to the corresponding EDCF priority queues. For most applications,
this approach offers a perfect balance between user experience and
complexity, and without imposing excessive overhead. |

Enterprise-Class Wireless
Security
|
|
| Our Real-AP/Bridge software solution provides the most
comprehensive set of multi-layered security features in the industry.
WEP, TKIP, and AES link layer encryption protects sensitive data from
exposure to malicious sniffer attacks. 802.1x port based access control
and several alternative upper layer authentication methods (EAP-MD5,
EAP-TLS, EAP-TTLS, EAP-FAST, LEAP, and PEAP) ensure that only authorized
users are allowed access to the wireless network. In addition, VPN
tunnels can be established via either IPSec, L2TP, or PPTP. |
|
Network Management
|
|
| The Real-AP/Bridge framework includes an embedded Web
server/graphical user interface (shown on this page) and a Command
Line Interface (CLI) for configuration, diagnostics, and management.
The CLI is available via TTY terminal or terminal emulator attached
directly to the serial port, or via telnet client. Full support for
SNMP v2c is also provided. |
