Mobile Network Evolution

Iqbal Zulkarnain./ Cellular Network Planning & Engineering Iqbal Zulkarnain./ Cellular Network Planning & Engineering Page 3






Evolution Driven by Competitive Pressures

Richer services and QoS require more

efficient broadband network:

High Peak Rate, Low Latency

Advanced QoS

Pressure of cost / profitability:

Traffic and subs increase requires more

spectrum efficient

With competitive tariff plans, maintaining

profitability means cost/MB has to be reduced.

Smooth evolution to protect investment.

Objective for LTE:

To develop the 3G access

to carry “everything”




Limitation in 3G :

• Cell breathing data speed increases the coverage area

of the cell become smaller and smaller

•Latency 100 ms for WCDMA, 80 ms for HSDPA

•Throughput max 168 Mbps with 4x4 MIMO

•Multiple Access technique CDMA, share same frequency, limited

in Power

•Limitation in HS User currently only 32 HS/cell

4G encompasses the pillar of Next Generation Network (NGN) :

Broadband wireless as the new access reality

• High-throughput, low latency, mobile access based on OFDM/MIMO,

efficiently delivering unicast, multicast and broadcast media.

Convergence of technology and networks • A single applications domain serving customers across multiple networks

and devices.

Intelligence at the services edge• Intelligence at the services edge Implementing policy enforcement and

decisions at the network edge, in an access-agnostic but access-aware

Technology shift to all-IP

• Simplifying and streamlining the network, improving scalability and

deployment flexibility, and enabling consistent access-aware policy

enforcement and billing

Embedded security

•A multi-layer, multi-vendor approach to security is critical to ensure that

security is endemic to the network and not just focused on point solutions.


Main Attributes:Core network IPv6 based

Better support of mobility, security and “unlimited” address space

Wireless access points become IP gateways

Different radio access technologies deployed within a domain

Optimization of the radio resources




4G Specific Requirement :

Low latency and high throughput

Efficient always-on operation, with instantaneous access to network

Resources

Support for real-time and non-real-time applications

Flexible spectrum allocations

Re-use of existing cell site infrastructure

High spectrum efficiency for unicast, multicast and broadcast data

Simplified Architecture



Two key enabling technologies will help the industry meet and exceed the

4G performance objective :

Orthogonal Frequency Division Multi plexing (OFDM)

• intrinsically able to handle the most common radio frequency (RF) distortions

without the need for complex equalization techniques, and scales easily to fit

different bandwidth requirements.

Multiple Input/Multiple Output (MIMO) •increases peak throughput by transmitting and receiving multiple streams of

information within the same spectrum. MIMO exploits the multi path effects typical

in wireless

More resource blocks a user gets, and the higher the modulation used in the resource elements, the higher

the bit-rate. Which resource blocks and how many the user gets at a given point in time depend on advanced

scheduling mechanisms in the frequency and time dimensions

WiMAX Operating Band :

Fixed WiMAX : 3.5 GHz and 5.8 GHz

Mobile WiMAX : 2.3 GHz, 2.5 GHz, 3.3 GHz dan 3.5 GHz

3.5 GHz for fixed WiMAX is common for Europe, Canada, Middle East,

Australia and part of Asia

2.5 GHz for Mobile WiMAX is common for operate in many country in the world

3.3 GHz band issue will take part in Asia due to 3.5 GHz to Satellite frequency,

will raise potential for interference
