InterDigital
Communications has selected Effnet's IPHC (IP Header Compression) product
for integration with InterDigital's FDD protocol stack product in order
to improve the efficiency of transmitting Internet Protocol (IP) traffic
over wireless networks and thereby lower the cost of IP feature services
for wireless operators.
InterDigital's FDD mobile
terminal software product is being designed to
take advantage of the converging IP-based internet and wireless link
technologies using Effnet's IPHC. "InterDigital is recognized as
a
leader in the development of technologies that will make data on the
go
a reality for mobile wireless communications worldwide," said Tony
Bowden, InterDigital's Senior Director, Software Product Management.
"Our selection of Effnet IPHC software is an element in our UMTS/FDD
protocol stack product development strategy that we believe will greatly
benefit our customers and wireless operators."
"When InterDigital was
looking for world-class Header Compression
software for its UMTS release 3 protocol stack, they came to Effnet,
the
leader in Header Compression technology," said Michael Stipe, VP
Sales &
Marketing, Effnet. "We are very excited with our new relationship
with
InterDigital. Our association will strengthen both company's market
offerings."
Header Compression reduces
the size of an IP packet header by removing
or shrinking header fields. When IP packet headers are compressed, more
of the packet's payload, or user data, is transferred in the same amount
of time. Header Compression means faster, more reliable and lower cost
services for wireless Internet operators and customers.
Effnet IPHC is a software
implementation of IETF RFC 2507, delivered as
an ANSI C language reference implementation, which runs on Sparc
(Solaris), x86 (Linux), and ARM7 but can easily be ported to other
platforms. It can optionally be provided with a test environment,
Effnet's HCSim product, which is used to validate operation when IPHC
is
integrated into the customer's target environment.
InterDigital's FDD
Layer 2/3 software protocol stack, designed for
portability, can be integrated onto multiple physical layer (Layer 1)
implementations and can act as the communications engine for a wide
range of 3G mobile devices and services. This complete UMTS FDD software
protocol stack is being designed to run on any real time operating
system and hardware platform, including existing FDD physical layer
implementations. It is fully compliant with the latest 3GPP release
99
(Mar 02) standard with optional features including Effnet's IPHC for
enhanced performance. InterDigital is employing a multiple-stage product
development process that facilitates technology transfer to customers
early in their design process making this software available now for
early integration into 3G terminal units. Effnet's IPHC will support
InterDigital's products and technology optimizing bandwidth utilization,
Data and IP based applications.
