Agilent adds Hearing-Aid Compatibility to its Antenna Modeling Design System (AMDS)

Agilent adds new capabilities to its Antenna Modeling Design System (AMDS), a 3-D modeling and verification tool for antenna systems and placement. The new version 2007.4, allows users to evaluate hearing-aid compatibility (HAC) between wireless communication devices and hearing aids. Development of the AMDS HAC functionality was accomplished through the joint efforts of Agilent's EEsof EDA R&D team and the development team at Remcom Inc.

Agilent Antenna Modeling Design System (AMDS) with Hearing-Aid Compatibility

Erwin De Baetselier, Agilent's EEsof EDA division, said:

By February 2008, all wireless carriers in the U.S. must ensure that 50 percent of their phones are hearing-aid compatible…

…Today, we are leading the industry by offering HAC compatibility tests in our EM simulation environment, ensuring that designers of wireless devices will be able to meet these important and rigorous specifications.

AMDS imports, meshes and simulates an entire wireless device, together with its surrounding real-world environment, to analyze compliance standards such as HAC, SAR (Specific Absorption Rate), and antenna diversity and MIMO (Multiple-Input, Multiple Output). Simulating the device with AMDS can reduce design cycle time significantly, eliminating up to 75 percent of the typical modeling and setup time that is required by other types of EM simulators.

The AMDS 3-D EM feature set includes:

• Efficient importation of CAD data from product designers, reducing or eliminating EM design iterations
• Verification of antenna compliance with legal and operational standards such as SAR, HAC, Over-the-Air Performance and MIMO
• Optimization of MIMO performance by analyzing antenna placement and diversity for the entire physical wireless appliance
• Optimization of device performance by simulating its real-world interaction with the human body

The Agilent AMDS is available. Prices start at US$50,000.
