The Latest Mobile Phone Technology
The latest mobile phone handsets provide a wide range of
services and technology that allows the user to be as interactive
as possible with the global community. These new mobile
technologies offer the user accessibility to the worldwide
web via WiFi connectivity, download and transfer large amounts
of data via high speed connectivity and find a location
via satellite with mobile Global Positioning Systems (GPS)
Todays mobile phones have now evolved to incorporate all
types of online activity, here is a little breakdown of
some of the latest technology to grasp the mobile market.
What is Wi-Fi?
WiFi is a wireless technology brand owned by the
Wi-Fi Alliance intended to improve the operating of
wireless products. Common applications for Wi-Fi include
Internet and VoIP phone access, gaming, and network
connectivity for consumer electronics such as mobile
phones, laptops, game consoles, MP3 players and PDA's.
Wi-Fi also allows connectivity which enables devices
to connect directly with each other. This connectivity
mode is useful in consumer electronics and gaming
It's faster and has a greater range than Bluetooth,
and is ideal for home or office connectivity. In the
near future, wireless networking may become so widespread
that you can access the Internet just about anywhere
at any time, without using wires. The easy access
of emails for business orientated individuals is also
a bonus, as urgent messages can be downloaded on the
go once the email settings are configured on to the
WiFi enabled handset.
The mobile phones market has received a lot of attention
lately as several operators across the world have
launched various types of handsets which allow users
to connect to the Internet via Wi-Fi, the iPhone being
the ultimate example.
A new study from a London-based research firm claims that
mobile voice-over-IP will become a mainstream form of communication
by the end of 2012, based on rapid growth of voice-over-3G
wireless users. Disruptive Analysis said its research shows
mobile VoIP will eclipse fixed-mobile convergence services
that use dual-mode handsets with voice-over-WiFi capabilities.
VoIP has become popular largely because of the cost advantages
to consumers over traditional telepone networks. VoIP calls
can be placed across the Internet. Most Internet connections
are charged using a flat fee structure. Using the Internet
connection for both data traffic and voice calls can allow
consumers to get rid of one monthly payment. In addition,
VoIP plans do not charge a per-minute fee for long distance.
For International calling, the monetary savings to the consumer
from switching to VoIP technology can be enormous.
Today, Skype, TruPhone and a company called Fring already
offer VoIP over 3G smartphones and 3G-enabled laptops allowing
users to communicate with other VoIP users via the Internet.
This service is expected to provide customers with a cheaper
alternative to connecting calls via GSM in the near future.
High-Speed Downlink Packet Access (HSDPA) is a 3G (third
generation) mobile telephony communications protocol in
the High-Speed Packet Access (HSPA) family, which allows
networks based on Universal Mobile Telecommunications System
(UMTS) to have higher data transfer speeds and capacity.
Current HSDPA deployments support down-link speeds of 1.8,
3.6, 7.2 and 14.4 Mbit/s. Further speed increases are planned
for the near future.
What is fourth generation (4G) mobile?
4G, an acronym for Fourth-Generation
Communications System, is a term used to describe the next
step in wireless communications. A 4G system will be able
to provide a comprehensive IP solution where voice, data
and streamed multimedia can be given to users on an "Anytime,
Anywhere" basis, and at higher data rates than previous
generations. There is no formal definition for what 4G is;
however, there are certain objectives that are projected
for 4G. These objectives include: that 4G will be a fully
IP-based integrated system. This will be achieved after
wired and wireless technologies converge and will be capable
of providing 100 Mbit/s and 1 Gbit/s speeds both indoors
and outdoors, with premium quality and high security. 4G
will offer all types of services at an affordable cost.
4G is being developed to accommodate
the quality of service (QoS) and rate requirements set by
forthcoming applications like wireless broadband access,
Multimedia Messaging Service, video chat, mobile TV, High
definition TV content, DVB, minimal service like voice and
data, and other streaming services for "anytime-anywhere".
4G in principle will allow high-quality smooth video transmission.
It will enable fast downloading of full-length songs or
music pieces in real time.
The business of 4Gmobile is
predicted to be huge. By 2009, this 4Gmobile market will
be over $400B. This 4Gmobile technology will dominate the
wireless communications, and its converged system will replace
most conventional wireless infrastructure.
What will the data rates
be for 4G?
At present the download speed
for mobile Internet connections range from 9.6 kbit/s for
2G cellular, up to 200 kbit/s (nominally 384 kbps) for the
new Vodafone 3G service (mentioned above). However, in actual
use the data rates are usually slower, especially in crowded
areas, or when the network is "congested".
4G mobile data transmission
rates are planned to be up to 20 megabits per second Thatís
about 10-20 times faster than standard ASDL services.
In terms of connection seeds,
4G will be about 200 times faster than present 2G mobile
data rates, and about 10 times faster than 3G broadband
mobile. 3G data rates are currently 2Mbit/sec, which is
very fast compared to 2G's 9.6Kbit/sec.
