W-CDMA

Joint Offer to Leverage ArrayComm’s Advanced Multi-antenna Signal Processing and Alvarion’s Industry-leading WiMAX Platform in 4Motion Mobile WiMAX Solution

TEL AVIV, ISRAEL and SAN JOSE, CALIFORNIA, July 26, 2007 — Alvarion Ltd. (NASDAQ: ALVR) and ArrayComm LLC, announced today their ongoing technology partnership for integration of ArrayComm’s multi-antenna signal processing software (A-MASTM) into Alvarion’s 4Motion’s Radio Access Network Solutions.

Alvarion is the world’s leading provider of WiMAX and wireless broadband solutions. Its all-IP OPEN WiMAX ecosystem opens the door to complete, best-of-breed networks that optimize all elements of a WiMAX network – from core equipment and service offerings to end-devices and even the end-user’s experience.

Alvarion’s WiMAX platform will leverage ArrayComm’s A-MASTM Advanced Multi-Antenna software in order to offer 2 to 4 times more coverage and spectral efficiency than the WiMAX Forum’sTM baseline profiles, through a unique combination of Beamforming, MIMO and adaptive interference cancellation, while maintaining full profile and standards compliance.

Power Amplifiers, Front-end Modules and Transceivers

According to the Strategy Analytics GaAs service report on 3GSM 2007, suppliers of power amplifiers, front-end modules and transceivers emphasized their strong product mixes to provision custom solutions at handset OEMs -- including cost-effective solutions for emerging regional markets and leading-edge products to meet the challenges of W-CDMA and beyond. Details on these products are can be found in "3GSM 2007 Show Report: Power Amplifiers, Front-end Modules and Transceivers."

GPRS handsets will continue to make up a significant portion of the cellular handset market, especially in emerging regional markets, while the momentum behind 3G/3.5G, and its successors, emphasizes requirements for multi-mode and multi-band architectures. GaAs device manufacturers demonstrated products at both ends of the spectrum.

W-CDMA (wideband code division multiple access)

W-CDMA (Wideband Code Division Multiple Access) is a type of 3G cellular network. W-CDMA is the technology behind the 3G UMTS standard and is allied with the 2G GSM standard.

More technically, W-CDMA is a wideband spread-spectrum 3G mobile telecommunication air interface that utilizes code division multiple access (or CDMA the general multiplexing scheme, not to be confused with CDMA the standard).

History

W-CDMA was developed by NTT DoCoMo as the air interface for their 3G network FOMA. Later NTT DoCoMo submitted the specification to the International Telecommunication Union (ITU) as a candidate for the international 3G standard known as IMT-2000. The ITU eventually accepted W-CDMA as part of the IMT-2000 family of 3G standards. Later, W-CDMA was selected as the air interface for UMTS, the 3G successor to GSM.
