Meru Radio Switch, RS4000 High Capacity Wireless LAN Access with Multi-mode & Multi-radio, Radio Switch Meru Networks' Radio Switch, RS4000 is the only way to add capacity to your enterprise WLAN without adding complexity. WLAN capacity problems can be addressed in University auditoriums and hospitals with voice and data Wi-Fi devices, high-density offices and other areas where multiple devices need access simultaneously. The Radio Switch is a plug-and-play upgrade to existing WLANs without the need to re-plan the wireless network. Built on standard, proven wireless networking technology, the Radio Switch uses Meru's industry leading RF intelligence and 802.11 technologies to re-write the rulebooks for enterprise WLAN deployments. The Radio Switch is unique in its simplicity. Just like wireless access points, the Radio Switch can be installed wherever wireless coverage is needed. For large buildings with multiple rooms and floors, more than one Radio Switch can be installed to cover the desired area. But, different than a typical access point, Radio Switch, RS4000 allows corporations to simultaneously deploy and use four 802.11 channels, resulting in a 400% increase of your WLAN network capacity. With Meru Networks, the unwired enterprise is a reality today. Four Radio Omni-directional Coverage The Radio Switch is ideal for indoor applications. Using Meru’s patent-pending wideband omnidirectional antenna, the Radio Switch can simultaneously serve multiple 802.11b/g and 802.11a channels throughout every square foot of the coverage area. With the Radio Switch, WLANs are no longer bound to density/performance trade-off rules governing the traditional access points. Upgrade Performance Without Changing Your Network Due to the limitations of other access points, WLAN performance and price were always thought to be tied together. If you wanted higher density coverage, you had to deploy more access points in order to serve more channels. The Radio Switch shatters this model by providing the performance of multiple access points in a single product. This results in a savings of over 70% in enterprise deployment and ongoing management costs. The Radio Switch’s omni- directional antenna enable enterprise IT departments to upgrade network capacity without ever worrying about changing the coverage area. The antenna is capable of serving all available channels simultaneously to every square foot of coverage area providing unprecedented voice and data performance at a fraction of the cost of traditional WLAN access points. Lower Operational Overhead With Better Application Performance Given the shared and random nature of the wireless medium, adding access points for capacity does not always work and often causes application failures which in turn increase IT helpdesk expenses. Meru’s Air Traffic Control technology furthers the innovation of the high-capacity Radio Switch by ensuring application performance. The Radio Switch monitors wireless clients and the associated traffic, and then spreads the load across its radios and different channels for better application performance. Combining the load-balancing techniques for superior traffic management with higher bandwidth from multiple radios, the Radio Switch is an ideal choice for high user-density WLANs. Investment Protection With Modular Architecture The Radio Switch is designed to grow with your bandwidth requirements. The modular “card-cage” chassis allows for simple & cost-effective field upgradeability to add up to 4 more 802.11a & 802.11b/g radios and a path to 802.11n radios (when available). The same wideband omni-directional antenna will extend to support the additional 802.11a & 802.11b/g radios. Wireless Specifications Wireless Interfaces 4 radios.
