Today’s enterprise business applications require the increased performance and reliability of WiFi to accommodate the massive influx of smartphones and tablets. These mobile devices do not have wired Ethernet ports, and Wi-Fi is the only way to connect these devices to the enterprise network.


When it comes to RF management, real-world Wi-Fi deployments suffer from three primary shortcomings:

  • Shared Media: Wi-Fi, like every other RF technology, is a shared medium. Since a fixed amount of channel bandwidth must be shared by all clients on a channel, clients must compete for bandwidth while simultaneously avoiding collisions

  • Multiple Client Technologies: In order to maintain interoperability with older clients, protective mechanisms have been incorporated into new, higher speed Wi-Fi technologies that force them to lower their operating speed in the presence of slower clients. The presence of even a single low-speed client can undermine the performance of nearby devices that would otherwise operate at higher speeds

  • Client-based decision-making: Clients decide to which access point they should associate, when to roam, and at what speed they should send and receive data. Unfortunately clients do not have a system-level view of the network, and as a result often make poor decisions because they lack a broader view of the network.

    These shortcomings can reduce overall client and network performance, a situation that ARM is designed specifically to address – without adding client software, without using non- standard system architectures, and without violating IEEE 802.11 standards.

These shortcomings can reduce overall client and Wi-Fi network performance.

What’s so great about Enterprise-grade Secure WLAN Technology?

  • It’s faster: 802.11n & 802.11ac technology delivers up to 300 Mbps & 1 Gigabit link speed for Wi-Fi radios compared to 54 Mbps with legacy 802.11a/b/g. This means increased bandwidth for end user and enterprise business applications.

  • It supports more users: 802.11n & 802.11ac lets users get the job done faster and at increased speeds. As a result, IT can support increased densities of enterprise wireless users with smartphones and tablets without worrying about network capacity.

  • It’s more reliable: 802.11n & 802.11ac uses multiple antennas to transmit and receive signals, while the old 802.11a/b/g uses only one to transmit and one antenna to receive. 802.11n & 802.11ac boosts the signal quality and reliability on both ends of the Wi-Fi connection, which accelerates the performance of enterprise business applications.

  • It’s secure: Home-use-grade Wireless LAN equipment is inexpensive and easy to install. Many employees will do it themselves, connecting wireless APs to your internal network. Enterprise-grade Wireless LAN Equipments knows the difference between your next door neighbor’s AP and a rogue AP on your network and will shut down the threats, Wi-Fi is secure enough that it is now being used by the military!

Understanding Enterprise-grade WLAN Technology

  • Adaptive Power and Channel Assignments

    Automatically assigns channel and power settings for all APs in the network. Includes support for 802.11n HT20 and HT40 channels.

  • Coordinated Access to a Single Channel

    Allows nearby APs on the same channel to share spectrum without increasing co- channel interference.

  • Band Steering

    Moving 5GHz-capable clients to the 5GHz band for higher performance.

  • Channel Load Balancing

    Ensures the even distribution of clients across available channels in a given area to avoid overloading a single channel or AP.

  • Airtime Fairness

    Provides equal access to the wireless medium for all clients, regardless of client type, capability, or operating system.

  • Airtime Performance Protection

    Delivers uniform performance for all clients by preventing clients, especially slower ones, from monopolizing resources.

  • Coverage Hole Detection

    Detects and notifies the network manager when clients are unable to associate at acceptable speeds.

  • Operating System Fingerprinting

    The OS fingerprinting feature gathers information about each client connected to determine what OS the client is running. This information enables IT to identify rogue clients, including clients running an OS not allowed on the company network, as well as clients with an outdated OS. OS fingerprinting also helps IT locate and patch clients with specific OS versions that have known vulnerabilities to fortify enterprise network security.

  • Applications Fingerprinting

    Application fingerprinting is a component of radio management technology. Using infrastructure-based controls, system auto-adapts to handle the traffic and compensate for interference, client density, adjacent networks, and other variables. Fingerprinting automatically detects latency-sensitive application and adjusts

    QoS and other parameters to ensure reliable and timely delivery – a feat that microcell and single channel Wi-Fi architectures can’t match.
