Eliminate access point (AP) brown outs and lock ups

AirEqualizer APs control congestion at the AP – without manual tuning.

AirEqualizer:
• Installs in minutes
• Automatically controls excessive use by non-priority users
• Ensures high quality for VoIP and priority users
• Dramatically reduces help desk and service calls

APs frequently suffer brownouts and lockups. But AirEqualizer APs automatically relieve congestion between AP and network or AP and Internet when usage levels reach 95% (or any chosen limit).

The easy-to-use, low-cost solution

AirEqualizer APs are economical because they simplify a very complex process – shaping traffic based on built-in fairness rules. AirEqualizer looks at current usage, including traffic levels and application types, and does not require manually-set policies.

When the AP is congested, AirEqualizer’s fairness algorithm favors business class applications so that large downloads don’t slow down latency-sensitive applications such as VoIP and video as well as ERM, CRM and other business critical applications.

AirEqualizer adds latency to non-priority flows that use excessive bandwidth over a period of time. If the flow continues to use too much bandwidth, its latency is further increased, automatically. It’s easy to exempt latency-sensitive, business critical applications that need substantial bandwidth.

FEATURES

Bandwidth limiting

AirEqualizer provides bandwidth-limiting features by:
• Fairness (favors bandwidth for web browsing, voice, chat and
   e-mail)
• Host (supports up to 4000 individual limits)
• Subnet
• MAC address
• Port

Built-in flexibility allows administrators and operators to change all settings in real-time, with no affect on access point service quality.

For voice customers, AirEqualizer has the ability to provide priority for all major IP PBX products and major Vendor Specific VoIP applications (VSVAs).

Commercial access point features

AirEqualizer includes authentication/redirection capability to detect new users and require them to sign up for service. Standard Linux utilities enable authentication and billing. Routing allows connections between user and Internet plus LAN connection to the next local AP in the same building.

Specifications

Each AP includes a weather resistant enclosure and mounting hardware for pole.

Unit can be supplied power by PoE (power over Ethernet) or an AC to DC power supply (sold separately).

Radio component is an 802.11b wireless mini-PCI module with Prism chipset. It is compatible to 802.11b 11Mbps WLAN technology.

Reporting

AirEqualizer offers key reporting features, including the ability to view connected wireless clients.

Firewall capabilities

AirEqualizer is protected with the standard IPtables or EBtables Linux firewall.

Connection limits

Connection limits allow customers to protect their APs from malicious activities, including:
• Worms that can hijack computers and quickly overwhelm access points with traffic storms
• p2p applications that bog down traffic and render firewalls useless if left unchecked.

Handling overloads from p2p applications can be labor intensive, but AirEqualizer’s connection limit feature prevents any single host from opening more than a set amount of connections.
