Wi-Fi Client Throughput—Maximized
Wireless is a shared medium, meaning that all clients and APs on the same channel compete for the same limited bandwidth. Each client’s throughput varies depending on the data rate it is using (802.11 a/b/g/n) at any given point in time, and this data rate may vary multiple times per second. or not. RSSI values, RF interference sources, signal blockage, and other factors play into a client device’s instantaneous data rate. RF interference, inconsistent RF coverage, clients connecting at the fringe of the network or moving behind obstructions, and older client devices using legacy modulation mechanisms all lead to low data-rate connections.
Dynamic Airtime Scheduling is a patent-pending wireless Quality of Service (QoS) technology from Aerohive Networks that can solve these problems.
The benefits of Dynamic Airtime Scheduling are compelling to both the IT organization and the users of the wireless LAN. It enables clients connected at higher data rates, in a mixed data rate environment, to achieve up to 10 times more throughput than they would get with traditional wireless LAN infrastructures – without penalizing clients connected at lower data rates. This means that the users see faster download times and improved application performance. It also means that low-speed clients can’t destroy the performance of the WLAN for the rest of the users. This allows IT to implement a phased upgrade to 802.11n and immediately start reaping the benefits of the new 802.11n infrastructure, even if it takes years to upgrade all of the clients. Because a user connecting at the fringe of the WLAN can no longer consume large amounts of airtime, the performance impact of a bad client or a weak coverage area is diminished, increasing user satisfaction.
Dynamic Airtime Scheduling, coupled with user and application-based policy enforcement, allows IT to manage wireless network resources to transform a shared WLAN into a true multi-service network infrastructure that makes it possible to reliably move users and applications to the air. Aerohive’s Dynamic Airtime Scheduling is a foundation, on top of which is built SLAs and policy-based airtime control – both of which are unique features in the enterprise Wi-Fi market.
