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. | According to the 4G working groups, the infrastructure and the terminals will have almost all the standards from 2G to 3G implemented.

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. | High Speed OFDM Packet Access (HSOPA) is a proposed part of 3GPP's Long Term Evolution (LTE) upgrade path for UMTS systems.

WiMAX
WiMAX Dashboard
- WiMAX is defined as "Worldwide Interoperability for Microwave Access" by the WiMAX Forum, formed in June 2001 to promote conformance and interoperability of the IEEE 802.16 standard, officially known as WirelessMAN. WiMAX aims to provide wireless data over long distances, in a variety of different ways, from point to point links to full mobile cellular type access. In practical terms this enables a user, for example, to browse the Internet on a laptop computer without physically connecting the laptop to a wall jack.
Spectrum coverage by geography Image below shows the spectrum for WiMAX users World wide.
Market research data:
- Worldwide WiMAX equipment revenues are forecast to reach $3.26 billion in 2009
- Worldwide outdoor wireless mesh access node sales are forecast to reach $1.17 billion in 2009
- Samsung leads overall WiMAX equipment revenue share in 3Q06, ahead of Alvarion, Airspan, and Aperto Networks
- Strix Systems leads overall outdoor mesh revenue market share in 3Q06, just ahead of Tropos Networks and BelAir Networks
- 35% of WiMAX equipment sales come from Asia Pacific, 30% from EMEA, 20% from North America, and 14% from CALA
- 49% of wireless mesh access node sales come from North America, 25% from EMEA, 18% from Asia Pacific, and 8% from CALA
- 802.16 standards The first 802.16 standard was approved in December 2001. It delivered a standard for point to multipoint Broadband Wireless transmission in the 10-66 GHz band, with only a Line of Sight (LOS) capability. It uses a single carrier (SC) physical (PHY) standard. Source
Standards
- IEEE 802.16-2004 (802.16d) addresses only fixed systems
- IEEE Std 802.16e-2005, also called mobile WiMAX
- 802.16e also bring Multiple Antenna Support through Multiple-input multiple-output communications. This brings potential benefits in terms of coverage, self installation, power consumption, frequency re-use and bandwidth efficiency. 802.16e also adds a capability for full mobility support.
- WiMAX II, 802.16m will be proposed for IMT-Advanced 4G (future development)
- 3GPP LTE and WiMAX-m are concentrating much effort on MIMO-AAS, mobile multi-hop relay networking and related developments needed to deliver 10X and higher Co-Channel reuse multiples.
IEEE 802.16e-2005 improves upon IEEE 802.16-2004 by:
- Scaling of the Fast Fourier Transform (FFT) to the channel bandwidth in order to keep the carrier spacing constant across different channel bandwidths (1.25-20 MHz). Constant carrier spacing results in a higher spectrum efficiency in wide channels, and a cost reduction in narrow channels. Also known as Scalable OFDMA (SOFDMA).
- Improving NLOS coverage by utilizing advanced antenna diversity schemes, and hybrid-Automatic Retransmission Request (hARQ)
- Improving coverage by introducing Adaptive Antenna Systems (AAS) and Multiple Input Multiple Output (MIMO) technology
- Increasing system gain by use of denser sub-channelization, thereby improving indoor penetration
- Introducing high-performance coding techniques such as Turbo Coding and Low-Density Parity Check (LDPC), enhancing security and NLOS performance
- Introducing downlink sub-channelization, allowing administrators to trade coverage for capacity or vice versa
- Enhanced Fast Fourier Transform algorithm can tolerate larger delay spreads, increasing resistance to multipath interference
- Adding an extra QoS class (enhanced real-time Polling Service) more appropriate for VoIP applications.
- Adding support for mobility (soft and hard handover between base stations). This is seen as one of the most important aspects of 802.16e-2005, and is the very basis of 'Mobile WiMAX'. Source

WiMAX Network Reference Model
Access Service network(ASN): The ASN coordinates traffic across multiple Base Transceiver Stations (BTS) and supports security, handoffs and Quality of Service (QoS).
- The ASN interfaces the BTS and the all-IP core network—the CSN. Typically the ASN includes numerous BTSs with one or more ASN gateways.
- The ASN manages radio resources, MS access, mobility, security and QoS. It acts as a relay for the CSN for IP address allocation and AAA functions.
Interface | Description | Functionality |
R1 | Interface between the MS and the ASN | Air interface |
R2 | Interface between the MS and the CSN | AAA (Authentication, Authorization, & Accounting ), IP host configuration, mobility management |
R3 | Interface between the ASN and the CSN | AAA, policy enforcement, mobility management |
R4 | Interface between the ASNs | Mobility management |
R5 | Interface between the CSNs | Internetworking,roaming |
R6 | Interface between BTS and ASN gateways | IP tunnel management to establish and release MS connection |
R8 | Interface between the BTSs | Handoffs |
ASN Gateway functions
- Service Flow Authorization
- Authentication and key distribution
- Session/Context maintenance
- Handover co-ordination & Mobility management
- Paging control
- Accounting client
- DHCP proxy/relay
- MIP client/FA
- Data-path management and (re)-anchoring
- Policy Enforcement
- Multiple BS, ASN, CSN configurations

WiBro
WiBro is an acronym for wireless broadband and is actually a term that is in the process of being phased out in favor of the more collaborative and generic Mobile WiMAX.
- Korean standards makers early on adopted the term to describe their initiatives towards adopting a version of the 802.16e standard.
- Basically, the Korean standard chose to accept a specific mobile WiMAX iteration of 802.16e, rather than any future version that included backwards compatibility to fixed wireless 802.16 systems.
- Korea enjoys probably the most extensive 3G deployments in the world already, and its fixed broadband access per capita is the highest in the world. What it needed was an improved mobile broadband. In fact, the Korean government issued the first three deployment licenses for WiBro/Mobile WiMAX in January of 2005.
- WiBro/Mobile WiMAX in many respects is driving the mobile side of WiMAX at least from the point of view of vendors eager to provide products to these early deployments. This decision however, results in a backwards compatibility problem with Fixed WiMAX standards or 802.16-2004.
- The smooth interoperability of previous WiBro gear from Samsung with other vendors such as Motorola should be cemented this year as these two companies along with Intel have been chosen as the primary vendor for Sprint Nextel’s WiMAX deployment. The two companies clearly have a powerful incentive for their products to work seamlessly.
Standards
- WiBro is an integral part of IEEE 802.16e
Companies
Industry news:
- South Korean telco SK Telecom and Wavesat, a Canadian developer of a WiMAX chipset, software and development platform have signed an agreement to cooperate in the development of WiBro/OFDMA technology for next generation mobile devices.
- Wavesat will work with SK Telecom (SKT) to develop WiBro/OFDMA systems-on-chips (SoCs), system tools and a development kit based on the WiBro 802.16e S-OFDMA profile. The U-mobile product portfolio from Wavesat will allow WiMAX wireless system providers (OEMs/ODMs) worldwide to develop and deploy fully mobile WiMAX and WiBro solutions.Source

3GPP Long Term Evolution
3GPP LTE (Long Term Evolution) is the name given to a project within the Third Generation Partnership Project to improve the UMTS mobile phone standard to cope with future requirements.
- LTE focus is on Enhancement of the Universal Terrestrial Radio Access (UTRA) and Optimisation of the UTRAN architecture.
- Downlink based on OFDMA (OFDMA offers improved spectral efficiency, capacity, etc)
- Uplink based on SC-FDMA (single carrier) (SC-FDMA is technically similar to OFDMA but is better suited for uplink from hand-held devices- more considerations on battery power)
Standards
- Download rates of 100 Mbit/s, and upload rates of 50 Mbit/s for every 20 MHz of spectrum
- At least 200 active users in every 5 MHz cell. (ie 200 active phone calls)
- Sub-5ms latency for small IP packets
- Increased spectrum flexibility, with spectrum slices as small as 1.25 MHz (and as large as 20 MHz) supported (W-CDMA requires 5 MHz slices, leading to some problems with roll-outs of the technology in countries where 5 MHz is a commonly allocated amount of spectrum, and is frequently already in use with legacy standards such as 2G GSM and cdmaOne.) Limiting sizes to 5 MHz also limited the amount of bandwidth per handset
- Optimal cell size of 5 km, 30 km sizes with reasonable performance, and up to 100 km cell sizes supported with acceptable performance
- Co-existence with legacy standards (users can transparently start a call or transfer of data in an area using an LTE standard, and, should coverage be unavailable, continue the operation without any action on their part using GSM/GPRS or W-CDMA-based UMTS)

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
- Flexible bandwidth usage with 1.25 MHz to 20 MHz bandwidths. By comparison, W-CDMA uses fixed size 5 MHz chunks of spectrum.
- Increased spectral efficiency at 2-4 times more than in 3GPP release 6, peak transfer rates of 100 Mbit/s for downlink and 50 Mbit/s for uplink.
- Latency times of around 20 ms for round trip time from user terminal to RAN, approximately the same as a combined HSDPA/HSUPA system, but much better than "classic" W-CDMA.
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.
