4G wireless technology developments

Overview

Definition of 4G

The 4G will be a fully IP-based integrated system of systems and network of networks achieved after the convergence of wired and wireless networks as well as computer, consumer electronics, communication technology, and several other convergences that will be capable of providing 100 Mbit/s and 1 Gbit/s, respectively, in outdoor and indoor environments with end-to-end QoS and high security, offering any kind of services anytime, anywhere, at affordable cost and one billing.

According to the 4G working groups, the infrastructure and the terminals will have almost all the standards from 2G to 3G implemented. The infrastructure will however only be packet based, all-IP. The system will also serve as an open platform where the new innovations can go with it.

Content delivery

QoS service for WiMAX Content Delivery as per standard

Service UGS RT-VR NRT-VR BE ERT-VR
Unsolicited Grant Service Real-Time Variable Rate Service Non-Real-Time Variable Rate service Best Efforts Service Extended Real-Time Variable Rate Service.
Real time service (e.g.VoIP) generating fixed data rate. Data can be provided as either fixed or variable length PDU. Real-time service (e.g.MPEG) applications with variable bit rates. Require guaranteed data rate and delay. Non Real time service (FTP) for guaranted data rate.This service is insensetive to delays.It is desirable in certain cases to limit the data rate of these services to some maximum rate. The intent of the BE service grant scheduling type is to provide efficient service for best effort traffic in the

uplink.

This service is to support real-time applications with variable data-rates, which require guaranteed data and delay, for example VoIP with silence suppression.

HSOPA

High Speed OFDM Packet Access (HSOPA) is a proposed part of 3GPP's Long Term Evolution (LTE) upgrade path for UMTS systems. HSOPA is also often referred to as Super 3G. If adopted, HSOPA succeeds HSDPA and HSUPA technologies specified in 3GPP releases 5 and 6. Unlike HSDPA or HSUPA, HSOPA is an entirely new air interface system, unrelated to and incompatible with W-CDMA. Features of HSOPA

Standards

Design

HSOPA uses Orthogonal Frequency Division Multiplexing (OFDM) and multiple-input multiple-output (MIMO) antenna technology to support up to 10 times as many users as W-CDMA based systems, with lower processing power required on each handset.[1]. Still in development, experimental performance is 37 Mbit/s in the downlink over a 5 MHz channel, close to the theoretical maximum of 40 Mbit/s.

3GPP2 Ultra Mobile Broadband

UMB (Ultra Mobile Broadband) is the brand name for the project within 3GPP2 to improve the CDMA2000 mobile phone standard for next generation applications and requirements.The system employs OFDMA technology along with advanced antenna techniques to provide peak rates of up to 280 Mbit/s.

Goals for UMB:

The technology will provide users with concurrent IP-based services in a full mobility environment. The UMB standardization is expected to be completed in mid 2007, with commercialization taking place around mid-2009.
