KT Corporation and ArrayComm announced today an agreement to collaborate on multi-antenna signal processing technologies for WiMAX/WiBro.

KT, South Korea’s largest telecommunications service provider, is building an advanced mobile broadband service in the 2.3 GHz band. WiBro, unlike the Mobile WiMAX standard, uses a fixed (2.3 GHz) spectrum without “smart” antenna technology. ArrayComm’s multi-antenna signal processing software (A-MAS) is being incorporated in WiBro and WiMAX client devices and base stations by multiple manufacturers to reduce costs and improve performance.

ArrayComm and KT teams will conduct joint efforts to demonstrate how ArrayComm software can provide benefits for KT’s WiBro initiative. They will conduct field trials in Q4 2006 to validate performance and refine product requirements to further enhance WiBro’s use of MAS technology.

“We expect that ArrayComm’s A-MAS software will give a significant performance improvement in the WiBro system” noted JongLok Yoon, Senior Executive Vice President at KT. “KT’s bold strategy for mobile broadband is charting a new course for service innovation and applications that will delight their customers,” observed Martin Cooper, ArrayComm’s Executive Chair.

KT and ArrayComm have agreed to make reports on the results of their collaboration available to others in the industry over the coming year.

The WiMAX profiles support both adaptive antenna system (AAS) and multiple-input/multiple-output (MIMO) architectures in baseline form. ArrayComm’s MAS implementation enhances baseline MIMO through the addition of interference mitigation.

ArrayComm explains Multi-Antenna signal processing Software (A-MAS) terms:

There is a lot of confusion in the industry today about multi-antenna architectures and processing modes. Commonly-used terms such as smart antennas, MIMO, adaptive antennas, or beamforming mean many different things to different people. We prefer to use the more general term multi-antenna signal processing (MAS) to refer to all architectures and processing modes, including several exclusive to ArrayComm.

In a system where multiple antennas are installed on the base station, the antennas create a focus of radio energy around each subscriber and create the absence of energy in the direction of other subscribers trying to use the same resource in neighboring sectors and cells. Our example 200-site network can now support 600 simultaneous connections with a single resource.

If we put multiple antennas on the client device as well (in a so-called MIMO architecture), then these spatial channels can be used to multiply the data rate to individual users.

ArrayCom claims their multi-antenna signal processing (MAS) solution includes unique support of MIMO, AAS (Adaptive Antenna Systems, also known as beamforming), and combined MIMO/AAS modes on both client devices and base stations will produce the best possible speed, range and network capacity. It is collaborating with Samsung, Texas Instruments, Intel and picoChip for hardware support.
