Overview

Q What is Mobile WiMAX?

Mobile WiMAX is based upon the IEEE 802.16 standard, enabling the delivery of wireless

broadband services anytime, anywhere. Samsung Mobile WiMAX can be used not only for

mobile environment but also for fixed and nomadic because it provides wider converge than

wireless LAN and as high as fixed data rate. Samsung Mobile WiMAX supports seamless data

service even at the speed of 120Km.

Q What will WiMAX services offer to the average consumer?

WiMAX networks will provide broadband connectivity and mobile Internet anytime, anywhere,

for any device.

Examples include:

High speed internet access where it is currently unavailable.

Substantially increase data speeds (over 2G/3G technologies) for applications to include

online gaming, streaming video, video conferencing, VoIP and location based services.

Drive wireless mobile Internet equipment and access prices to an open and competitive

price point

In the U.S., Mobile WiMAX services from Sprint and Clearwire will reach more than 150

million consumers by year end 2010.

In rural areas, WiMAX technology will establish an affordable and efficient broadband

network. The purchase and installation process of WiMAX technology is faster, simpler and

cheaper than other offered solutions. Additionally, the non-line-of-sight (NLoS) capability

means that WiMAX technology can provide coverage despite the challenges of geography

and the limited footprint of wireline-based solutions.

In developing countries, WiMAX technology provides the opportunity to connect people

with Internet and VOIP services faster and more affordably than wireline technology.

Up 384Kbps 384Kbps 5.6Mbps 4.03Mbps 5Mbps 10.08Mbps

Q What are Wave1 and Wave2?

Wave 1 and Wave2 are definition of certification for Mobile WiMAX. The WiMAX Forum

organization divided certification test cases into Wave1 and Wave2 considering market situation

and technology maturity. Basic features were included Wave1 and advanced features like MIMO

(Multiple Input Multiple Output), Beamforming, MBS (Multicast and Broadcast Service) were

defined Wave2 certification. Wave1 (2.3G profile 1A) was already launched since 2006 in

Korea. Most of other countries are waiting for Wave2 (2.5G).

Q Which company has certified products?

WiMAX Forum defines and conducts conformance and interoperability testing to ensure that

different vendor systems work seamlessly with one another. Those that pass the harsh testing has

been received the WiMAX Forum Certified designation and Samsung got all sort of

certifications from device to base station WiMAX Forum has finished until now. In fact, except

Sequans, which is a chip vendor, Samsung is the only company who has certified products in all

part.

Q What is MIMO?

MIMO (Multiple-Input and Multiple-Output) is the use of multiple antennas at both the

transmitter and receiver to improve communication performance. It offers significant increases

in data throughput and link range without additional bandwidth or transmit power. It achieves

this by higher spectral efficiency (more bps/Hz of bandwidth) and link reliability or diversity

-13-

(reduced fading).

Q What is Beam-Forming?

Beamforming takes advantage of interference to change the directionality of the array. When

transmitting, a beam-former controls the phase and relative amplitude of the signal at each

transmitter, in order to create a pattern of constructive and destructive interference in the wave

front. When receiving, information from different sensors is combined in such a way that the

expected pattern of radiation is preferentially observed.

Q What is orthogonal frequency division multiplexing (OFDM)?

OFDM is a digital encoding and modulation technology. It has been used successfully in wire-

line access applications, such as Digital Subscriber Line (DSL) modems and cable modems as

well as WiFi. Products from WiMAX Forum member companies are using OFDM-based 802.16

systems to overcome the challenges of NLoS propagation.

OFDM achieves high data rate and efficiency by using multiple carrier signals instead of just

one. All future 4G technologies will be based upon OFDM.

Orthogonal Frequency Division Multiple Access (OFDMA) is enhanced OFDM and used in

Mobile WiMAX technology and the IEEE 802.16e-2005 standard, and it is the foundation for

the next-generations of mobile broadband to come. It is a multi-user version of Orthogonal

Frequency-Division Multiplexing (OFDM). The difference between the two technologies is that

OFDMA assigns subsets of sub-carriers to individual users allowing simultaneous low data rate

transmission from several users.

Q How does WiMAX technology compare to broadband and Wi-Fi transfer

speeds?

WiMAX provides high-speed broadband connection to the Internet and is typically deployed on

a city wide, region or even nationwide basis. Wi-Fi is a wireless local area network technology.

WiMAX and Wi-Fi are complementary as WiMAX provides the wide-area access and Wi-Fi can

provide the local area access. Numerous device manufacturers/CE companies are incorporating

Wi-Fi/WiMAX modems into portable devices and mini PCs. The application will automatically

select the best connection based on the availability of service at a certain location.

Q What is IMT-2000 and define its current relationship with WiMAX

technologies?

In 1999 the International Telecommunications Union – Radio communications (ITU-R) defined

a set of standards called IMT-2000, commonly known as 3G technologies. These technologies

benefit from access to harmonized spectrum bands worldwide that facilitate global economies of

scale. The IMT-2000 provides a framework for worldwide wireless access by linking the diverse

systems of terrestrial and satellite based networks. Since the original IMT-2000 standards were

agreed upon, updates have been made but no new standards have been approved.

The IEEE submitted a formal proposal to the ITU-R to make a subset of the 802.16 (WiMAX)

standard a member of the IMT-2000 family, as defined by ITU-R recommendations. The process

of considering the submission began in Cameroon in January. A special meeting of ITU-R

Working Party 8F was held in Seoul Korea Aug 29-31st in an attempt to complete consensus on

the inclusion of WiMAX into the IMT-2000 set of standards. As a result, three draft

recommendations have been forwarded to the Study Group 8 (parent group) chair for

consideration at the upcoming Radiocommunications Assembly October 15-22 in Geneva.

The WiMAX Forum provided substantial supporting material in order to make WiMAX a

member of the IMT-2000 family. The WiMAX Forum was instrumental in the development of

the supporting material necessary to include WiMAX in the IMT-2000 family.

Q What is the difference between IEEE 802.16 and WiMAX technology?

One of the main objectives of the WiMAX Forum is to certify products based upon the IEEE

802.16 and ETSI HiperMAN harmonized standard. WiMAX Forum defines a System Profiles

based upon what the WiMAX Forum determines in terms of service provider and vendor

equipment demand.

Compliance with the 802.16 standard does not mean equipment is WiMAX Forum Certified™ or

that it is interoperable with other vendors’ equipment. However, if a piece of equipment has

earned the WiMAX Forum Certified™ designation, it is both compliant with the 802.16 standard

and interoperable with other vendors’ equipment that is also WiMAX Forum Certified.

Q What is the 802.16m standard?

802.16m is the next generation standard beyond 802.16e-2005 and will become adopted by the

WiMAX Forum once the standard is completed in the 2009 time frame. 802.16m is considered

to be a leading candidate as a 4G technology.

Q What is OPA (Open Patent Alliance)?

Samsung is one of the 6 companies who formed Open Patent Alliance. The purpose of OPA is

making a WiMAX patent pool to help participating companies obtain licenses from patent

owners at a predictable cost.

This will bring the openness of the Internet and computing industries to the wireless industry

and WiMAX, stimulating a larger WiMAX industry.

The OPA will issue a call for WiMAX essential patents for inclusion in its patent pool. An

independent third-party reviewer will serve as the "patent referee" and will evaluate submitted

patents to determine how essential they are to the WiMAX standard and WiMAX Forum

profiles.

It is just first step for making patent pool, but very strong. This is not just association but a

invested company. This shows the will of Mobile WiMAX industry to make the pool.

- OPA is an alliance formed to advance development of 4G WiMAX.

- It is for advance a competitive, open intellectual property rights model

- It enables a large, more competitive WiMAX industry that supports innovation

Investors

Alcatel-Lucent, Cisco, Clearwire, Intel Corp., Samsung Electronics and Sprint

Purpose

The alliance will advance a competitive and open intellectual property rights model, stimulating

a larger WiMAX industry that supports innovation through broader choice, and lower equipment

and service costs for WiMAX technology, devices and applications globally.

Activities

OPA will form a WiMAX patent pool to help participating companies obtain access to patent

licenses from patent owners at a predictable cost. The patent pool will aggregate essential patent

rights needed to implement the WiMAX standard as defined by the WiMAX Forum and the

IEEE 802.16e standard.

To help ensure product differentiation and interoperability at a more predictable cost, this

approach will focus on providing a more competitive royalty structure by charging only for the

features required to develop WiMAX products. The patent pool will incorporate a variety of

royalty licensing solutions, including accounting for cross-licensing among individual members

within the pool.

In addition to the formation of a WiMAX patent pool, the OPA will educate the WiMAX

ecosystem about, and serve as a central resource for WiMAX intellectual property rights topics.

The OPA will issue a call for WiMAX essential patents for inclusion in its patent pool. An

-16-

independent third-party reviewer will serve as the "patent referee" and will evaluate submitted

patents to determine how essential they are to the WiMAX standard and WiMAX Forum

profiles. While the OPA initially will focus its efforts on the WiMAX standard, it may work with

other industry groups in the future.

Made up of six founding companies at its inception, the OPA expects to secure participation of

an additional six to nine investor companies to encompass the WiMAX value-chain and broad

geographic representation. Each investor company will have a seat on the OPA board of

directors. The OPA will have dedicated staff that is directed by and accountable to the OPA

board, and the alliance will serve as the licensing agent for the WiMAX patent pool,

representing the licensors who agree to participate in the pool.
