Meru Walks Through WLAN

Meru Networks brings virtual reality to wireless LAN management

SUNNYVALE, Calif. -- Meru Networks has introduced a network management software product that lets users "walk" through three-dimensional representations of their Meru wireless LAN deployments, seeing detailed, real- time, color-coded views of network coverage and signal propagation patterns throughout buildings, across campuses and even in remote sites.

Using a wireless version of the advanced 3D monitoring and visualization techniques found in medical imaging and architectural systems, Meru Wireless Virtual Reality shows users areas of weak or strong coverage as well as floor-to- floor and cross-elevation interactions that are difficult, if not impossible, to understand with existing 2D monitoring technologies. Fully immersed in the deployment, users can move in all three dimensions of the radio- frequency (RF) environment, seeing properties of the wireless coverage from any position or angle.

The easy-to-use Wireless Virtual Reality system requires only that the user upload floor plans, enter floor and building locations, and drag-and-drop access points onto the map. The Wireless Virtual Reality engine then creates a 3D walkthrough that reveals the nature of the complex interactions of wireless propagation throughout the deployment. Because no complex RF modeling is required of the user, setup is greatly simplified and the potential for inaccuracy minimized.

Do 3D 'Virtual Walkthrough' Without Leaving the Desk

With Meru Wireless Virtual Reality, users can do a virtual 'walkthrough' from their desks, viewing walls, floors, access points, clients and other wireless devices across the entire deployment. They can monitor coverage patterns and wireless system behavior in physically remote or difficult-to-reach areas, saving time in visiting those sites or gaining visibility that would otherwise be unavailable.

In comparison, said Joe Epstein, Meru's senior director of technology, "the most sophisticated 2D 'heatmap'-based management tools are limited in their ability to show the complex nature of RF coverage spanning multiple stories within buildings. Current tools cannot easily or accurately represent irregular building spaces, such as high-ceilinged auditoriums or low mezzanines, or distinguish between interference coming from a weak signal nearby or a strong one three floors below. These kinds of capabilities will become even more critical as growing numbers of users adopt IEEE 802.11n technology and need a way to understand the complexities of its impact on network performance."
