Flextronics Software Systems is a global leader in technology
for the future. Read more on how we cater to Voice over Packet,
Wireless, SS7 and Broadband domains and keep pace with rapidly
evolving industry standards...
VoP (Voice over Packet)
Internet Protocol (IP) is used for the transmission of data,
primarily between computers over the Internet. Voice over
IP (VoIP) takes standard
voice signals and encodes them using IP.
At present, most voice signals are carried using circuit switched
bearers where a channel is set up and maintained between the
calling and called parties for the duration of the call. IP
technology divides the voice signal into packets and each
packet is sent separately. This usage is commonly referred
to as Voice over Packet (VoP).
This means that the total bandwidth required can be reduced
since nothing needs to be sent when the caller is not speaking.
Benefits of VoP are the ability
to get international calls at local rates by routing voice
traffic over the Internet and the future convergence of today's
networks into a single network for voice and data traffic.
This would result in scale and operational economies while
opening up possibilities for providing more innovative services.

offerings.
The Road to 3G:
GSM (Global System for Mobile Communications) is the second
generation of mobile communications. The first generation
was analog radio telephony. GSM represents the first time
that digital radio technology was used.
With the evolution of the internet and the progressive requirement
of the mobile users seeking access to data availability worldwide,
networks started exploring with data transfers over GSM networks.
Charting a roadmap of increasing the data transfer rates from
9.6 kbps for a typical SMS (Short Message Service) message
over GSM to 132 kbps and finally 2mbps for multimedia content,
OEMs (Original Equipment Manufacturers) and network implementors
worldwide initiated or started working on standards that would
enable this data rate. 2.5G or the first step towards the
mobile internet is facilitated through standards like GPRS
(General Packet Radio Service) and EDGE. Both use the GSM
technology as its base. 3G (Third Generation) or UMTS (Universal
Mobile Telecommunications Systems) is expected to be the final
stage of evolution in the journey towards delivering high
density content to increasingly small mobile devices.
GPRS
The General Packet Radio Service (GPRS),
an enhancement to the existing GSM and Time Division Multiple
Access (TDMA) networks, is a new non-voice value added service
that allows information to be sent and received across a mobile
telephone network. It supplements today's Circuit Switched
Data and Short Message Service and provides users with "always
on" connectivity and greater bandwidth, thus using the
radio spectrum optimally.
GPRS allows you permanent access to the e-mail, Internet
and other services, allowing a free flow of information. At
last true freeflow information is for reals!
Our suite of High Speed Mobile Data products allow mobile
infrastructure vendors to leapfrog from second generation
mobile technologies to 2G+ and third generation (3G) technologies.
Our offerings hinge about Stacks and Frameworks that enable
an equipment manufacturer of reduce time to market by porting
the frameworks on the desired platform and creating the services
to provide the differentiators.

offerings.
UMTS - 3G
3G or third generation of mobile communication brings to life
the full potential of the mobile internet, opening up new
vistas of communication, accessing information, conducting
business and also being entertained. Think about this. You
are travelling and its lunchtime. You consult your mobile
phone, select the online guide that is location sensitive,
review and select the restaurant of choice and confirm your
booking online.
This is no dream. 3G or Universal Mobile Telecommunications
System (UMTS) is a new
radio communications technology that will provide high-speed
mobile access to Internet-based services, enhancing and extending
mobility in many areas of our lives. UMTS is a part of the
International Telecommunications Union's 'IMT-2000' vision
of a global family of 'third-generation' (3G) mobile communications
systems.
We at Flextronics Software Systems are committed to spearheading
the evolution to the 3rd Generation of mobile communication
- UMTS, that will deliver high-value broadband information,
commerce and entertainment services to mobile users via fixed,
wireless and satellite networks.
Find out more about our UMTS
offerings.
EDGE
The explosive demand for mobile communications is rapidly
paving the way for GSM operators to develop new applications
that bridge GSM and TDMA networks into third generation technology.
We at Flextronics Software Systems provide solutions that
introduces a new modulation technique through Enhanced data
for GSM Evolution (EDGE) that would offer 3G mobile internet
solutions using the existing infrastructure. EDGE, a third
generation radio interface technology is the next step in
the GSM technology that offers high 3G speed in mobile internet
technologies.
Protocol
Stacks
A protocol defines a set of rules and conventions for
communication between network devices.
Protocol stacks classify a "language" or an ascendancy
of instructions that instruct paths, formats and delivery
between and within networks. These could include formatting
rules on signalling and routing a message - voice or data
between networks, and also how data is packaged into messages.
It also may include conventions like message acknowledgement
or data compression to support reliable and/or high-performance
communication.
Flextronics Software Systems' high performance, high-availability,
interoperable and versatile Protocol Stack software reduce
time, risk and cost of implementing the Next Generation of
Communication Networks and enhancing traditional networks
with Voice Over Packet and High Speed Mobile Data capability.
Flextronics Software Systems has protocol stacks like SIP,
H.323, H.248,
MGCP, MEGACO
etc. for enabling Voice over packet network solutions, B-SS7,
GPRS, UMTS,
MAP and RANAP
for 3G / 2.5G mobile networks as well as V5,
VB5
and other standards based communications protocol stacks for
enhancing traditional networks. With Flextronics Software
Systems stacks you achieve faster time to market and rapid
network roll out.
