802.11n’s intimidating nomenclature contains such mysterious terms as MIMO, spatial streams and spatial multiplexing, which can quickly freeze a network manager’s brain. What do these specs really ...

802.11n is expected to be ratified later this year and to provide speeds of up to 600 Mbps, which is over ten times faster than the existing standards. 802.11n also has other benefits such as ...

‘We established in the last newsletter that you need multiple transmit and receive antennas working in parallel (a.k.a. “MIMO” technology) to conduct spatial multiplexing. We also learned that spatial ...

Spatial modulation (SM) and multiple‐input multiple‐output (MIMO) systems represent a significant advance in wireless communication technology. By utilising the spatial dimension, SM encodes part of ...

MIMO (Multiple Input Multiple Output) is expected to become popular as a solution to enhance data throughput and quality of communication in complex propagation environments. This article discusses ...

The 11n standard is based on orthogonal frequency-division multiplexing (OFDM), which is also used in the 802.11a/g standards. It's a proven way to extend range and data rate in multipath environments ...

Multiple antenna schemes are becoming a key part in almost every new wireless standard. For example, the UMTS/W-CDMA standard uses transmit diversity to improve the link quality in outdoor ...

Multiple Input, Multiple Output wireless technologies [1, 2, 3, 4, 5] are getting a lot of attention these days. MIMO has the ability to significantly increase raw ...

Technical advances in the development of telecommunication basestations and mobile stations with MIMO are demanding more functionality from test equipment. All of today’s advanced radio networks, ...
