Multiple Input, Multiple Output (MIMO) technology is a wireless technology that uses multiple transmitters and receivers to transfer more data at the same time. MIMO technology takes advantage of a radio-wave phenomenon called multipath where transmitted information bounces off walls, ceilings, and other objects, reaching the receiving antenna multiple times via different angles and at slightly different times.

MIMO technology leverages multipath behavior by using multiple, “smart” transmitters and receivers with an added “spatial” dimension to dramatically increase performance and range. MIMO allows multiple antennas to send and receive multiple spatial streams at the same time. This allows antennas to transmit and receive simultaneously.

MIMO makes antennas work smarter by enabling them to combine data streams arriving from different paths and at different times to effectively increase receiver signal-capturing power. Smart antennas use spatial diversity technology, which puts surplus antennas to good use. If there are more antennas than spatial streams, as in a 2x3 (two transmitting, three receiving) antenna configuration, then the third antenna can add receiver diversity and increase range.

Radio Frequency Identification (RFID) is a system that facilitates the tracking of objects, primarily for inventory tracking, via a three part technology comprised of a reader, a transceiver with decoder and a transponder (RF tag). RFID is a wireless system that works in conjunction with an organization’s information technology infrastructure to improve business processes such as inventory management and efficiency in supply chain management.

RFID is one of several technologies collectively known as Auto-ID procedures – procedures for identifying objects automatically. Companies are increasingly deploying Auto-ID procedures in their supply chains. RFID is already used in several areas of everyday life, such as in the central locking systems for vehicles. RFID functions are now integrated in passports and will even find their way into health cards. This white paper provides an overview of the technical aspects of RFID systems.

WirelessHD is an effort to define a specification for the next generation wireless digital network interface for wireless high-definition signal transmission for consumer electronics products. The consortium currently has over 40 adopters. Key members behind the specification include Broadcom, Intel, LG, Panasonic, NEC, Samsung, SiBEAM, Sony, Philips and Toshiba. It was finalized it in January 2008.

The WirelessHD specification will serve as the first and only wireless digital interface to combine uncompressed high-definition video, multi-channel audio, intelligent format and control data, and Hollywood approved standard content protection techniques. For end-users, elimination of cables for audio and video dramatically simplifies home theater system installation and eliminates the traditional need to locate source devices in the proximity of the display. The WirelessHD specification is based on the 7GHz of continuous bandwidth around the 60GHz radio frequency and allows for uncompressed, digital transmission of full HD video and audio and data signals, essentially making it equivalent, in theory, to wireless HDMI. The specification has been designed and optimized for wireless display connectivity, achieving in its first generation implementation high-speed rates from 4 Gbit/s for portable
