4th Generation Wireless Technology – Application Model of Future Mobile Communications Systems

4G (Fourth Generation) Mobile Communication is still in evolution but countries have already started committing themselves to its implementation. India has said that it would leapfrog from 2G to 4G bypassing the 3G Technology. WiMax Technology is on its last legs because it does not support VoIP. Data transfers will happen at LAN Speeds of 100Mbps. The World is looking up to 4G for transformation of the way people do day-to-day business. Once the technology evolves, the hand phone used in 4G mobile communications would be an all in one device for use in education, arts and science, business activities outside the office, network games and music/video content downloading, Visual Communication, merchandise purchase and settlement, and daily life.

A few applications…

Medical Applications Overview of Evaluation by Potential Service Providers- The certainty and stability of connection were raised as the primary requirements on the communications infrastructure to realize medical services that take advantage of mobile communications. While it may be feasible to provide full-fledged remote medical treatment easily through high-quality images enabled by faster transmission speeds, stable uninterrupted communication was regarded indispensable and more important in the medical field.

Also, it is widely known that the provision of medical services are subject to many legal and regulatory restrictions. Consequently, services that can be offered by private entities are currently very limited. It has been pointed out on various occasions that this has hindered the flexible offering of new services in the medical field. This issue remains unsolved today, and no significant change can be expected soon, either. According to the opinions of potential service providers, the first steps to be taken would be to develop technologies and services and educate the medical industry so that consumers could generally share the recognition that high-quality medical service can be provided safely and securely through electronic medical records and networks.

Ultimate Content Player Simply by instructing the name of video (which does not necessarily have to be precise; ambiguous input will do) of users’ choice (TV programs broadcast in the past, news, dramas, movies, or concerts, etc.) through voice input, etc., users will be able to watch it on a mobile terminal through streaming from the network anytime and anywhere they like.

The charges for the content- which should be decided taking into account the requests of the rights holder, the number of accesses from users (popularity), video quality, the number of copies, the time of viewing, location, etc.-will be present on the spot, and if the user agrees, the video will be made available for viewing. Also, when the user wants to see a movie using some spare time, for instance, during a business trip, he/she can search information concerning the movies currently on show and see a preview on the player. If he/she decides to watch the whole movie in a cinema, it is possible to search the theater that can be reached from the current location before the start of the movie, and if necessary, make a seat reservation and purchase electronic tickets, too. The videos can be viewed in trains on a spectacles-type display, which can be suspended for a moment when changing train

Navigation System Users will be able to gain access the following information services from inside moving vehicles. The information will be provided adequately depending on time, location and properties of user. Users may also be able to receive discounts at shops by presenting the information retrieved through the above. – Location information service (locating service, route guide, traffic information, etc.) – Vehicle information service (automobile information, vehicle tune-up information, etc). – Entertainment service (radio, TV programs, etc). – Control service (vehicle control if earthquake, accident, etc). – Emergency service (accident, sudden illness, etc). – Logistics service (parcel delivery, etc).

Mobile Ordering Enables easy purchase of products or obtainment of information simply by holding a mobile terminal toward printed materials (magazines, brochures, posters, etc.) or images. Information concerning the product (video, CM, specifications) will be automatically delivered to the mobile terminal from the product center, and displayed in 3D images, which can be viewed from multiple angles. Users, if they like, can order the product on the spot, make the payment and settle the accounts from a mobile terminal. Sales status in the areas nearby, and other related information on the product could also be obtained. The use of retinal authentication makes it possible to purchase expensive products without any security concerns.

From the viewpoint of the potential providers of settlement service, the reliability and cost of authentication hold the key for the settlement of purchases made at shops through mobile terminals, and ordering service linked with brochures and posters in the streets. When compared with credit card payments at shops or shopping from PCs/TV, the purchases to be made from mobile terminals are expected to be lower in amount but more frequent. It is therefore essential for the providers of settlement services that the authentication of the terminal and the users themselves, which have to be conducted every time a purchase is made, can be realized at a low cost equal with the low unit purchase amount.

Related Entities’ Evaluations and Expectations on this Application Evaluation on the presumed application Mobile settlement is already provided in existing mail-order service through product bar codes in the catalogs. This service is realistic as an extension of such existing services, enabling users to order more easily. Evaluation on Landline Internet became wide spread before the establishment of a content billing mechanism. On the other hand, wireless Internet provided a billing mechanism from the beginning, thus users developed the recognition to pay for premium contents. If services leveraging the display feature of mobile terminals that cannot be provided by ordinary credit cards (such as provision and display of coupons) can be realized, it may be possible to enlarge the market size.

Presumed business model Required conditions for the service to be A low-cost authentication method must be realized. Because the amount of unit purchase is projected to be small, the authentication scheme is the better the cheaper.

Food Manager Enables users to gain access the home refrigerator using a mobile terminal from outdoors-to see what is left with visual images or to confirm whether the consumption deadline for some food has expired or not. Users can also obtain recipes of menus that can be cooked with the food available in the refrigerator from the mobile terminal. Lacking food items will be presented on the screen, and if ordered, they will be delivered to the home by the evening.

If the users register in the mobile terminal the food items that they want to keep always in stock, when they pass in front of this item at a supermarket, its purchase may be recommended automatically. Or, just by holding the terminal close to the refrigerator, list of food items out of supply could be sent to food delivery companies to have them delivered to the home on the same day or in a few days.

After a few order placements, it will become possible to estimate the user’s consumption behavior. From the next time, therefore, an inquiry could be sent from the server center, asking, for example, “do you still have plenty of beer?”

Disaster Insurance For example, when somebody is crushed under the debris in a large-scale earthquake, the locating capability of cellular phones can provide precise information about the location of this person-the terminal is always connected to the Internet unless it is broken-and enables rescue activities to be undertaken swiftly. This service enables search of people holding a terminal within a certain area regardless of the carrier. Entities that are responsible for providing safety and reliability to users, such as government bodies and

Mobile Administrative Services Users can instantly access information and receive various administrative services from national/local governments from a mobile terminal from home or offices.
