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 Aricent 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 Aricent 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.
Aricent's 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.
Aricent 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 Aricent stacks you achieve
faster time to market and rapid network roll out.
