Ericsson is introducing the world's first router optimized to handle realtime services in wireless networks. It enables operators to build all-
IP wireless networks that can handle demanding, realtime services with
telecom-grade quality. Based on a realtime sensitive implementation of
existing and emerging open Internet standards, it allows for
interoperability with other vendors' equipment.
The Ericsson Realtime Router RXI 820 is an industry first of its kind -
specifically designed to efficiently handle the special characteristics of
wireless access networks. These networks have demanding requirements, such
as synchronization of base stations, use of narrowband links, and
provision of delay sensitive services.
The new router is based on Ericsson's platform for 3G systems, and features interfaces with special hardware for efficient packet forwarding
performance. It incorporates a feature-rich Internet software protocol suite acquired through Ericsson's majority investment in Telebit, enhanced for wireless networks.
The Ericsson RXI 820 provides advanced quality of service for delay-sensitive traffic, outstanding performance, reduced operational
expenditure, and a highly scalable telecommunications-grade platform with
no single point of failure. It is future proof, handling both Internet Protocol version 4 (IPv4) and Internet Protocol version 6 (IPv6), as well
as transition between the two.
The RXI 820 is part of Ericsson's total solution for delivery of IP-based realtime services in wireless networks. The realtime router technology of the RXI 820 will also be embedded in other 2G and 3G radio network nodes, such as media gateways and base stations, ensuring end-to-end realtime performance.
It is supported by a new advanced IP layer management system, the IP Layer
Manager (ILM). The ILM is an open, standards based and modular system for managing very large-scale wireless IP networks. Through advanced automatic configuration, performance monitoring and simulation capabilities, it simplifies management of complex networks, substantially reducing the operational costs.
The Ericsson Realtime Router RXI 820 and the IP Layer Manager marks an important step forward in the transition to all-IP based wireless
IP-based networks can offer operators, faced with a new traffic mix, significant advantages - simplicity and reduced operational costs, more
efficient utilization of network resources, and new revenue opportunities through enhanced service offerings to their users.
Ericsson is the leading provider in the new telecoms world, with communications solutions that combine telecom and datacom technologies with freedom of mobility for the user. With more than 100,000 employees in
140 countries, Ericsson simplifies communications for its customers - network operators, service providers, enterprises and consumers - theworld over.
About Ericsson Telebit
Ericsson acquired a 75 percent stake in Danish company Telebit Communications A/S in June 1999.
Having developed the world's most advanced IPv6 router, the company is the first vendor to provide commercially available Internet router solutions based on new generation Internet standards, commonly referred to as IP
version 6 (IPv6). The company's dual IPv4/IPv6 products interoperate with IPv4 systems as well as IPv6, the new generation Internet.

Internet Protocol version 4 (IPv4) was designed in the early 1980s. The
accelerating growth of the Internet, the migration of the Internet into
new areas such as embedded devices, and the widespread use of IP in
wireless consumer devices, provide a new and different set of growthchallenges.
These devices will be the next generation of cellular phones, pagers,
Personal Digital Assistants (PDAs), digital cameras and a variety of
embedded devices. To address the issues with the growing Internet, the
IETF (Internet Engineering Task Force) has devised a new standard, IPv6,
to extend the current IP infrastructure. The new standard improves
scalability and security of IP networks, and also provides mechanisms for
easier configuration of networks and attached devices.
