Q. What is M-Drive Technology?
A. Cisco M-Drive Technology is a system-wide feature for the Cisco Unified Wireless Network that improves the predictability of the RF environment, while simplifying RF management for the enterprise. RF management is an area that enterprises consistently identify as a pain point. Most enterprises do not have the RF expertise necessary to properly manage their RF environment. Most also complain that the RF frequency is unpredictable, and that they have trouble ensuring that their wireless network scales and maintains the uptime they require. In addition, they feel that securing the wireless network is a complex and time-consuming process. Cisco M-Drive addresses these issues by providing innovations in RF management that improve predictability, reduce downtime and simplify previously-complex management tasks. With existing 802.11n solutions, the beam strength is not directed to the client, resulting in a sub-optimal client connection for 802.11a/g clients and coverage holes. Cisco M-Drive with ClientLink is a new, intelligent beam forming technology that directs the signal to improve performance (by up to 40%) and coverage for 802.11a/g devices. M-Drive also improves predictability of wired networks with wireless through interference mitigation, automated channel assignment, load balancing for optimized client connections and automated removal of coverage holes. Finally, M-Drive's centralized RF and system management removes the complexity from these management tasks - saving time and money for enterprise IT departments.

802.11n

Q. What is IEEE 802.11n?
A. IEEE 802.11n is a new wireless standard designed to deliver up to nine times the performance of existing 802.11a/g networks performance. The standard allows operation in both the 2.4-GHz and 5-GHz frequencies, and is backward-compatible with existing 802.11a/b/g networks. The Wi-Fi Alliance has begun certification of 802.11n products adhering to the draft 2.0 standard. This certification will ensure interoperability between access points and devices.
Q. What about my investment in 802.11a/b/g?
A. 802.11a and 802.11g each offer a 54-Mbps data rate, supporting a broad range of applications, including voice and video. With the relative under-utilization of these frequencies, especially the 5-GHz band, and the large installed base of 802.11a/b/g clients, most enterprises should anticipate their investments in business-class 802.11a/b/g access points to have many years of service. Additionally, the 802.11n standard requires backward compatibility with existing 802.11a/b/g infrastructure. Cisco expects 802.11a/b/g and 802.11n technologies to coexist for a long time.
Q. Do Distributed Antenna Systems (DAS) work with 802.11n?
A. MIMO technology relies extensively on multiple transmitters and multiple receivers to attain the throughput, reliability, and predictability benefits of 802.11n. The current generation of DAS systems only support a single transmit/receive chain per access point. Therefore, the throughput, reliability, and predictability benefits of 802.11n will be lost when used in conjunction with a DAS.
Q. What are the differences in performance between a 2x3 and a 3x3 MIMO implementation?
A. Theoretical calculations show that a 3x3 radio will have slightly better performance over a 2x3 radio. However, in our real world performance testing we have not seen any significant performance differences between 2x3 and 3x3 implementations. Note that the current generation of both 2x3 and 3x3 802.11n silicon supports up to 2 spatial streams, so there is no throughput advantage for a 3x3 implementation.
