Wireless LAN

Use of radio frequency (RF) as a means for transporting applications is already revolutionising communications. The convenience and freedom promised by wireless is driving its adoption exponentially - so it is really a matter of when and how enterprises will adopt wireless technology, not if. Still, historic concerns and problems associated with wireless technology are still rife in nearly all the available solutions. That's why Sigma Technology works with Airespace, the leading wireless supplier, to deliver the following benefits of the Airespace system:

• ease of deployment and use
• system robustness
• cost-effectiveness
• support for real-time applications
• location tracking
• security
• flexibility

Ease Of Deployment and Use

Sigma's Airespace implementation allows the rapid deployment of enterprise wireless solutions with minimal staff increases or extensive RF training.

System Robustness

The Airespace system offered by Sigma provides a complete solution, incorporating:

• reliable for service
• security - prevention and protection
• mobility
• real-time applications.

Cost-effectiveness

Sigma's Airespace offering reduces the capital requirements for wireless deployment and tackles the key financial challenges of operating a wireless LAN.

Support for Real-time Applications

Real-time applications demand quality of service (QoS) guarantees. Providing the right QoS is extremely difficult in a wireless environment. Sigma's Airespace deployments allow IT Staff to control key WLAN attributes, such as QoS, to support all voice and data business applications with real-time capabilities.

Location Tracking

The Airespace system that Sigma provides is the only WLAN platform that identifies and tracks wireless clients as they roam throughout a wireless network. This location-tracking feature is tightly coupled with other capabilities that enable:

• accurate RF planning
• tighter WLAN security
• real-time capacity management
• support for new wireless applications, such as voice.

Security

Sigma Technology understands the importance of network security, which is why we have chosen Airespace as our wireless LAN partner. Airespace offers the industry's only completely integrated solution for wireless protection, and it requires no separate application protocols, monitoring devices, or network appliances. Whether preventing wireless services altogether or protecting an existing corporate WLAN from unauthorized activity - such as wireless intrusion - Airespace has all of the tools necessary to protect your wireless domain.

Flexibility

Airespace's leading capabilities are available across a wide range of products suitable for Organisations of all sizes. Sigma Technology has the expertise to deliver those products, from something as small as a switch with 6, 12, or 24 port switches, to high-capacity appliances. We can deploy the Airespace system in the wiring closet, the distribution layer, or the data centre - across one site or many - using layer two and layer three connections. This makes the Airespace system an ideal fit for any enterprise environment.
