4G DEFINITION

4G is not one defined technology or standard, but

rather a collection of technologies and protocols

aimed at creating fully packet-switched networks

optimized for data.

4G networks are projected to provide speeds of

100 Mbps on move and 1 Gbps while stationary.

EVOLUTION OF DATA STANDARDS

1G was an analog system, and was developedin the seventies, 1G had two majorimprovements, this was the invention of themicroprocessor, and the digital transform of thecontrol link between the phone and the cell site.

Advance mobile phone system (AMPS) wasfirst launched by the US and is a 1G mobilesystem. Based on FDMA, it allows users to makevoice calls in 1 country

Second Generation Cellular

Communication (2G)

2G digital technologies can be divided into two

standards:

TDMA (Time Division Multiple Access)

- GSM: Originally from Europe but used

worldwide

- iDEN: Proprietary network used by Nextel in the

US

- PDC: Used exclusively in Japan

CDMA (Code Division Multiple Access)

- IS-95: Commonly referred to as CDMA and used

in the Americas and parts of Asia

EVOLUTION OF DATA STANDARDS

(3G)Third Generation CellularCommunication

3G networks provide the ability totransfer voice data and non-voice data(music downloads, emails and instantmessaging) over the same networksimultaneously.

3G technology supports around 144Kbps, with high speed movement, i.e. in avehicle. 384 Kbps locally, and up to2Mbps for fixed stations, i.e. in abuilding.

Standards:

- W-CDMA: Wideband Code DivisionMultiple Access

- EVDO: Evolution-Data Optimized

3G VS. 4G

Less Complexity, Faster Transmission

Unlike the 3G networks which are a combination of circuit switched and packet

switched networks, 4G will be based on packet switching only. This will allow

low-latency data transmission.

3G

Leading U.S. Carrier 3G

EVDO network currently

averages 400 to 700 Kbps

with peak rates up to 2

Mbps.

4G

International Carrier is

testing 4G communication

at 100 Mbps on move, and

1 Gbps while stationary.

4G COMPONENTS & TECHNOLOGY

Software-Defined Radio (SDR)

SDR is one form of open wireless architecture (OWA). Since 4G is a collection of wireless standards, the final form of a 4G device will constitute various standards. This can be efficiently realized using SDR technology, which is categorized to the area of the radio convergence

Orthogonal Frequency Division Multiplexing (OFDM)

OFDM is a technology that allows transmitting very high data rates over channels at a comparable low complexity.

WIMAX WiMAX (Worldwide Interoperability for

Microwave Access) is a telecommunications protocol

that provide fixed and fully mobile internet access. The

current WiMAX revision provides up to 40 Mb/s with

the IEEE 802.16m update expected offer up to 1 Gb/s

fixed speeds. The name "WiMAX" was created by the

WiMAX Forum, which was formed in June 2001 to

promote conformity and interoperability of the

standard. The forum describes WiMAX as:

“A standards-based technology enabling the delivery

of last mile wireless broadband access as an alternative

to cable and DSL”.

4G3G

2G

1G There are two main applications of WiMAX:

1) Fixed WiMAX (IEEE 802.16-2004) - Fixed WiMAX applications

are point-to-multipoint enabling the delivery of last mile wireless

broadband access as an alternative to cable and DSL for homes and

businesses.

2) Mobile WiMAX (IEEE 802.16e-2005) - Mobile WiMAX offers the

full mobility of cellular networks at true broadband speeds.

4G POSSIBILITIES

Enhanced Mobile Gaming 4G3G

2G

1G

Experience enhanced wireless capabilities

that deliver mobile gaming interaction

with latency less than five milliseconds.

Play online multiplayer games while

traveling at high speeds or sitting outside.

4G POSSIBILITIES

Personal Media Repository

Create a personal media repository

that can be accessed from home and

on the road to view photos, watch

movies and listen to your personal

music collection.

4G POSSIBILITIES

Virtual Presence

Use hologram-generating virtual reality

programs that provide an artificial

presence just about anywhere.

For example, decide if you want to

personally respond when someone rings

your front door while you are away from

home.

4G POSSIBILITIES

Broadband Access in Remote

Locations

4G networks will provide a wireless

alternative for broadband access to

residential and business customers.

In addition, 4G will provide the first

opportunity for broadband access in

remote locations without an

infrastructure to support cable or

DSL access.

WIMAX VS. WI-FI

WiMAX and Wi-Fi are somewhat independent, addressing slightly different needs.

WiMAX uses private, licensed spectrum and provides Wi-Fi-like service with guaranteed performance to larger public areas, similar in coverage to cellular networks today.

Wi-Fi uses shared spectrum and operates at short distances, making it ideal for low-cost, private networks (where usage of the network is constrained to an office building or campus) or free public systems (where service guarantees are not required).

THE ROAD AHEAD

GOING FORWARD WITH 4G

4G ACCESS OPTIONS

Embed 4G technology

into all end-user

devices

Develop mobile

personal gateways

Develop external

interfaces with 4G

peripherals

The lack of clarity and overuse of the term 4G could prove its

biggest opportunity, or could spell its premature demise.

As carriers begin to rollout 3G the term 4G may be rendered

meaningless by lack of definition.

However, the rollout of mobile broadband will have a profound

impact on the way we work and live.

This Is the Beginning…….
