WiMAX application content

Application services: VoIP and voice services

Currently, carriers that WiMAX core critical content is to provide m-VoIP (mobile telephone network), but in order to extend the scope of the large user populations, and on the basis of the content diversity

You must first launch m-VoIP business. For example, KT will be launched in late April DBDM (DualBandDualMode) smartphone plans starting from the month of April, the use of a Terminal at the same time provide WiBro and 2G voice service. This is to make voice calls WiBro Terminal implementation, further expanding the WiBro users.

Application services II: IPTV and other audio and video delivery

Study of WiMAX technology is suitable for HDTV, IPTV service transmission technology for wireless communication consultant WMXsystem in December 2006, published research results show that the WiMAX technology transfer IPTV services transfer rate and cost-effectiveness, simple, lightweight, convenient, and other characteristics to measure the HDTV, IPTV services provides technologies that copper wire, coaxial cable and satellite technologies, such as the transport medium in the per-user cost considerations and ARPU income are unable to compete with WiMAX, WiMAX to provide IPTV service for the future of technology.

IPTV may be used as General TriplePlay third in sub-item image transfer technology, WiMAX, WiMAX service will let operators and cable TV or satellite TV, the same television programme service depends on the compression technology, IPTV in WiMAX base stations and client devices often need to 1Mbit/s of bandwidth resources.

In addition to General TV programmes, WiMAX service operators can also provide VoD services by WiMAX, the user may own preferences of single points of their favorite TV shows, as opposed to past shows how all the required purchase paid subscription, saving not favorite program subscription costs, more attractive to consumers. WiMAX service operators of IPTV services also can supply to regional programmes, and from regional advertising the availability of additional revenue.

Application project three: comprehensive wireless application content

According to Nortel, the WiMAX market like digital cameras, MP3 3 class of 50 million devices should be linked with your broadband network, that is, through the WiMAX technology could put a notebook computer, gaming devices, and even cars, houses, and a network connection, but the current 3G.

To this end, the operator can try WiMAX provide more 3G is currently not available.

In Taiwan, Chunghwa Telecom "through" WiMAX wireless broadband network as Ilan County residents, tourists and business people to provide wireless broadband network access services (including VoIP and voice services, etc.), provide for Ilan County schools online learning program (M-Learning), Ilan County Government provides mobile-commerce (M-Commerce), mobile tourism (M-Tour), video security monitoring services (video surveillance) and Internet TV (IPTV) services.

WiMAX scenario

Application of places: cities and towns in the region

At present, China Taipei, United States-New York, San Francisco and Philadelphia, as well as Seoul, Tokyo and other cities are developing wireless city plan, ZTE recently in Mexico City have to be similar to the network, using WiMAX + WiFi technology.

Beijing also building wireless city plan and preliminary determine audio communications and low-speed data communication will use TD-SCDMA network, high speed data services will use the WLAN and WiMAX. By then, participate in the Beijing Olympic Games to millions of people will enjoy the wireless high-speed data communication services.

Application of places: rural areas

In the United Kingdom, according to wireless broadband carriers Telabria said that apart from the metropolitan area, the lack of broadband network services is, wired broadband infrastructure; to the southeast of England's Kent County area, less than 16% of symmetric digital subscriber lines (SDSL) coverage, this condition table names the local population to enjoy such as VoIP Internet phone, network, video, and other required high download/upload bandwidth demand application service is convenient.

Telabria in local deployment WiMAX service Skylink, this is a combination of data and voice network services, the provision of local households and enterprises of the "last mile" of networking access scheme.

Application of places: emerging ISP market

For example, in a fixed network operators a dominance of the region, new ISP are often difficult to compete with the traditional phone companies, since lack xinxing ISP infrastructure and line, takes a large cost to lease line toll to operations.

In order to be able to give a lot of broadband carriers in operational aspects of fair competition, and at the same time introduce more inexpensive and convenient networking services to consumers, local Government actively planning another "last mile" broadband alternatives, and WiMAX wireless broadband network technology can become entrepreneurs operating the "last mile" alternative. It can be said that in these emerging WiMAX ISP market, to bring them and the traditional telephone company competitive technology base.

Applies the place 4: enterprise market

Typically, large enterprise companies bandwidth needs ranging from DSL and T1, but DSL for them is clearly not sufficient, it is natural that they would hire a T1 line, T1 too wasted, while WiMAX broadband wireless to exactly meet their needs.

Currently, WiMAX technology in China also used primarily in the enterprise market, participation in the deployment of carrier China Telecom and China Netcom. It is understood, Guangdong Province, Hunan province and Zhejiang province's portion of the region has been deployed, Beijing, Heilongjiang, 9 provinces have begun to test cloth mesh.

By the end of 2006, Hubei Province people's Government and Samsung Electronics Korea signed the "wireless broadband industry development framework cooperation agreement", to determine this WIM based on 802.16e

AX early will promote cooperation and the trial stage, positioning network and industrial customers, depending on the situation of designated frequency bands, the business will be to 512Kbit/s ~ 2Mbit/s, the main application is the high speed video monitoring (e.g., highway patrol video), streaming video, live broadcast, etc. In addition, currently in construction, Xuanwu District, Beijing, 15 WiMAX base station network is for government environmental sanitation Department provides wireless broadband services; in the forestry sector of the forest fire prevention, WiMAX video transmission effects are fairly smooth.

WiMAX trial operation

At present, in Korea launch WiMAX commercial operation of a full service carrier KT, from 4 to begin in early 2007 to expand the user formally launched publicity and marketing activities, and in April 2007 the latest WiMAX business ideas.

First, the KT WiBro brand established as "KTWiBro": brand themes identified as "mobile Internet" Korea, a new brand to W-centric, designed as a semicircle, W is the pursuit of WiBrostyle KT.

Semi-circular and rich color implies the user's interaction and communication, to show individuality. Determine the brand, but also used the "Internet" slogan KoreaPortable.

Secondly, WiBro positioning 3.9 generation technologies, HSDPA at 3.5 generation technologies, to provide Beyond3G business expectations will make every effort, KT WiBro comprehensive Open Mobile by 2.0 times.

Third, WiBro business coverage to Seoul global and Metro, national capital region main University Street and other regions.

Fourth, the use of bundling overcome cover defects.

From 5 March, KT WiBro and KTF launched by combining with HSDPA USB modem "IPLUGPremium" business, and PCMCIA cards and laptops etc to WiBro built-in single form of business expansion for bundled products.

KT WiBro HSDPA and combining two technologies, according to consumer demand for wireless data usage will fall into both HSDPA and WiBro implementation strategy: plans in Seoul full domain and Metro line no. 1 ~ 8, national capital region's major cities and University Street offers WiBro, HSDPA in other areas.

Launched at the end of the 3 KT DBDM (DualBandDualMode) smartphone plans starting from the month of April, the use of a Terminal at the same time provide WiBro and 2G voice business, this is to make voice calls WiBro Terminal implementation, further expanding the WiBro users.

Fifth, the "WiBro HSDPA +" and "WiBro + 2G voice" bundle price discount rate is the key to expanding the user

Sixth, a comprehensive business-ready content to ensure the WiBro.

In addition to the 3 month supply of a single Internet access business, provides shopping, traffic, financial, and other lifestyle information-business and business-additional customization.

Particularly in education, starting from the month of April is not just B2C, B2B to object to the adoption of smart phones and PMP, UMPC (ultra-mobile PC) and many other foreign WiBro Terminal offers, business, innovation, leadership, and so video lectures on business.

The establishment of a unified platform for WiBroUCC provides high-definition large-capacity UCC business, through the business so that the user does not have a video device is capable of producing video content and upload, and create a personal media era.

WiBro is the core of key content provide m-VoIP (mobile telephone network).

In order to substantially expand its user base, on the basis of the diversity of content, you must first launch m-VoIP business.

In short, in the capacity of the network is currently HSDPA after WiBro, KT WiBro, HSDPA group bundled and 2G business is in order to expand the mobile user and mastery of the wireless data market, and the expansion of users – the key is to provide low-cost bundling products and applications on the use of WiBro provides to the user experience of mobile high-speed Internet access, open mobile, that is, the current era of 2.0 mobile business is to download, but will then enter the download and upload both times.

In Beijing, WiMAX network is ready to begin trial operation.

This network is currently using fixed IEEE802.16d access, you can access the nomadic State; but the operation initially would not provide for VoIP Internet phone support. As for the rate and fee, and the current ADSL fairly; and WiMAX will "translate" into a WiFi signal, the current Centrino or equipped with a wireless network card PC can receive.

Summary

WiMAX 3 g as ADSL and one supplementary scheme, and 3G, ADSL service to a competitive or complementary to the trends, on the one hand, allowing operators to take into account their needs, the development of appropriate technology, more stretch of space; on the other hand allows the market to full competition, consumers can enjoy its benefits.

Especially for some existing 3 g mobile operator, in the development, promotion of WiMAX, may face both 3 g and WiMAX services content, therefore, competition between operators, potential must be through the technical level of the difference to the content on the service, for both 3 g and WiMAX services complement each other.
