Salient features of 3G technology:

• It has introduced more efficient ways of carrying data with faster web services.
• Live chat, fast downloading, videoconferencing, etc., are also possible over mobile phones.
• It allows the user to play 3D games.

• A user can see live streaming on smartphones.
• It provides broadband internet services.

• It allows the user to send and receive large email messages.
• High bandwidth is required.

• Splits channel into time intervals enabling a single user to get all the resources at once.
 4G Technology

Unlike previous generations of mobile technology, 4G mobile technology uses ultra-high
broadband internet services with much faster data speed, typically between 100 mbps–
1gbps. Now, 4G rules the mobile market. Unlike previous generations of mobile technology,
4G mobile technology is used for internet access on computers also, and it is totally wireless.
4G provides internet access, high quality streaming video and “anytime, anywhere” voice and
data transmission at a much faster speed than 3G. The “anytime, anywhere” feature of 4G is
also referred to as “MAGIC” (Mobile multimedia; Anytime/anywhere; Global mobility support;
Integrated wireless solution; Customized personal services).

8.16 MOBILE PROCESSORS

Processors are required to run an operating system,
be it a desktop, laptop or a mobile. Processors
provide the necessary resources to start an operating
system, run applications and do certain tasks.
Today’s smartphones and mobile processors are very
powerful, so much so that they can compete with
desktop computers.

Processors are now available in many cores. First it was single core, then came the dual core, and
we now have quad core, hexa core and even octa core processors. Most processors available today
are 64-bit as against 32-bit earlier. The processing speed has also touched 3.0–3.5 GHz now. The
ability to equip mobile processors with GPU (Graphics Processing Unit) has enabled the devices Computer Networks
to churn out best graphic pictures, have 3-D capability, Virtual Reality and 4K recording capability.
The improved processor technology has also made modern mobile devices more power-efficient.
