IBM Enables a Single Device to Roam Across Multiple Types of Wireless Networks

Seamless Roaming allows Cellular, WLAN, Satellite and Radio Networks
to Act as One
ARMONK, N.Y., August 15, 2002 . . . IBM today announced the capability to
offer seamless, secure roaming between different types of wireless
networks including Wireless LAN, cellular, private mobile radio and
satellite networks. With the new Everyplace Wireless Gateway solution it
is possible to have access to critical business data at all times, moving
from location to location while roaming over different types of networks,
using different types of wireless device.
Generally, devices that can access different types of wireless network
applications need to be restarted when changing networks. IBM's Everyplace
Wireless Gateway automatically detects the most appropriate wireless
network at any given time and can switch networks without the need to
restart the device or the application. For example, a business person at
home can access data from a home wireless LAN network. After leaving the
house and out of range of the wireless LAN network, the device
automatically switches over to a cellular network. Upon entering the office
or a customer location the device can switch over to a higher speed Wired
or Wireless Local Area Network.
The solution also recognizes the most appropriate time and network to
transfer large amounts of data to and from the device and back end systems,
avoiding the use of more costly, slower speed cellular networks if large
amounts of data that can wait for a less expensive, higher bandwidth Wi-Fi
or Wireless LAN network.
"Wireless technologies are the next logical step in e-business and there is
no need for businesses to be limited a single type of wireless network to
access critical business data," said Adel Al-Saleh, general manager, IBM
Wireless e-business Solutions. "With IBM's new roaming solution data can
be accessed regardless of the wireless network that is available at a given
location."
The Toronto Police Service will use Everyplace Wireless Gateway to power
its eCOPS (Enterprise Case and Occurrence Processing System). Currently
under development, eCOPS will enable wireless devices in the patrol cars to
seamlessly roam between lower speed, but wider reaching, Radio Networks and
strategically placed Wi-Fi networks, enabling the faster exchange of data
when needed. When eCOPS is deployed police officers will increase
productivity with the ability to file reports in real time regardless of
their location. Additionally urgent information on suspected criminals
will be put in the hand of officers in the matter of seconds thereby
increasing the safety of the citizens and the Officer. This can also lead
to the early arrest of criminals and recovery of stolen goods.
"Given the level of security needed to communicate sensitive police data
wirelessly over multiple types of networks IBM's Everyplace Wireless
Gateway should be the premier choice for law enforcement agencies to
consider," said Chris Pentleton, Pentleton Consulting, the IBM business
partner that designed and is implementing eCOPS. "We took advantage of the
EWG toolkit to provide this roaming capability and with the incorporation
of this technology directly into the product, we are confident that EWG
will provide the Toronto Police with the technology it needs now and in the
future."
The main features of EWG solution include:
** Seamless Cross Network Roaming: EWG supports dynamic roaming across
physical networks without breaking the application sessions. Enables mobile
users uninterrupted connectivity to critical applications while moving
across networks.
** Multiple Network Choices: Extensive selection of wireless and
wireline network technologies across the world. (Cellular Networks, Public
Packet-Radio Networks, Internet Connections, Dial Connections, Private
Packet Networks, Satellite Networks, and LAN Connections). EWG is hardware
vendor and media independent.
** High Security: The EWG provides strong authentication and supports
RSA Secure ID. Customers can choose from an extensive cryptographic library
which includes: DES, Triple DES, RC5 and AES, to provide end-to-end
encryption of all data from the EWG, over the wireless networks, and to the
mobile devices. EWG is undergoing the FIPS140 certification to meet the
most stringent U.S. Government security standards.
** Performance Optimizations: EWG reduces data transmission costs over
wireless networks. It provides efficient data compression, connectivity
management and optimizes session transport for IP based wireless networks,
including 2.5G and 3G. Also enables optimized IP transport over non-IP
wireless packet networks. Improves speed, reliability, and end user
experience.
** Scalable and Reliable: The EWG supports gateway clustering, and can
distribute across multiple sites, to scale with your mobile needs. In
addition, the EWG supports High Availability Cluster Multiprocessing
(HACMP) to provide 24x7 reliability.
The IBM Everyplace Wireless Gateway can also be used by Service Providers
to offer seamless roaming between their wireless wide area (2.5G/3G) and
public wireless LAN networks.
EWG is optimized for IBM pSeries and also includes the Everyplace Client
that resides on the device. A full range of services are also available to
help customers design and implement the roaming solution.
