  6. The major premises for the usage of the M-business are: • 1. The widespread use and pervasion of Internet on a global scale, as well as at a national level; • 2. The widespread usage of the mobile communications, their accessibility, in terms of the coverage of the corresponding regions, as well as services’ prices Finland-IP-04-2007

  7. The mobile operators expect that because of the better potentiality of the networks and services in 2007, the mobile data market will go beyond 150 milliard dollars. Finland-IP-04-2007

  8. Mobile operator. This is a company, which provides mobile communication services. It is in possession of communication infrastructure, techniques and technologies for mobile communications. Finland-IP-04-2007

  9. Some more facts, which prove the growth of the mobile industry and the development of the M-business: • every quarter the number of companies developing software for mobile devices increases by 1000; • in 2005 the number of sold multifunctional mobile devices (PDA and smart phones) exceed the number of sold personal computers; • up to 2010 over 1 000 000 000 users will use wireless Internet; • up to 2010 there will be more than 1 800 000 000 users of the mobile communications. Finland-IP-04-2007

  11. Internet telephony market will explode from 130000 subscribers at the end of 2003 to 17,5 million subscribers in 2008. Finland-IP-04-2007

  12. Mobile users, % by years. Finland-IP-04-2007

  13. What is the situation in Bulgaria? In absolute expression the Internet users, during 2005, will be about 1 200 000, that is 16% of the country population. Finland-IP-04-2007

  14. Causes for M-business Adoption • The increasing mobility of today's workforce; • The convergence of telecommunications and software industries; • The increasing need for information and transactions anytime and anywhere; • The new breed of wireless handsets coming on the market; • The revenue opportunities created via location-based services and M-Commerce; • The productivity improvements to be gained via wireless extensions to enterprise applications and processes; • The improvements in bandwidth brought about by the migration from 2G to 2.5G and 3G networks; • The adoption of wireless standards such as Wireless Application Protocol (WAP), Bluetooth, and others. Finland-IP-04-2007

  15. Bandwidth (of a transmission channel). Usually the range of frequencies passed by channel. This will often consist of a single passband, but may instead consist of several distinct (nonoverlapping) passbands. Each passband contributes to the bandwidth of the channel a quantity equal to the difference between its upper and lower frequency limits. The sum of all such differences gives the total bandwidth. Bluetooth. Technology for wireless connection between different mobile devices and computer periphery (printers, mousse, web cameras, digital cameras and others). Finland-IP-04-2007

  16. Barriers to M-business Adoption • Business barriers; • Technology barriers. Finland-IP-04-2007

  17. Business BarriersOn a macro scale such as the creation of an entirely new business, the following standard questions may apply: • Can a business make money by using this model? • What is the nature of the product or service being offered? • Who are the customers and how will they benefit from this product or service? • What is the point of pain that is being removed? • What is the size of the market and the differentiation from the competition? • What is the pricing strategy and how will the service be delivered? • What channels will be used to promote the product or service? • What should the branding strategy be? • Are end users ready for this service? Finland-IP-04-2007

  18. On a smaller scale, such as a new business initiative within an enterprise, the following questions may apply: • Will end-users accept the technology and process change? • Will it provide enhanced customer service or improved employee productivity? • How will this be measured? • How will end users transition from prior processes into this new process? • What is the return on investment? • What is the learning curve for end-users? • What training is required? • What support services are required? • What service level agreements need to be in place? • How critical is this new application to the business?

  30. WAP – Wireless Application Protocol An example of a protocol that uses the GSM network is WAP. It is invented for mobile Internet. The WAP standard defines a set of technical specifications for delivering Internet communications and advanced telephony services on digital mobile phones, pagers, personal digital assistants, and other wireless terminals. Finland-IP-04-2007

  31. General Packet Radio System (GPRS) Between 1999 and 2001 GPRS was developed and tested. After 2001 GPRS was introduced to the public. It was still in development and during the year 2002 it became ready. Finland-IP-04-2007

  33. Universal Mobile Telecommunications System (UMTS) • This technology was launched for the first time in the United Kingdom in 2003, and was called THREE. In 2004, after a year of more research and development, the UMTS was launched all over the world. It is called the third generation phones (3G). • UMTS is a different technology and has his own network unlike GPRS. Still we can say that UMTS is a mixture of its predecessors. Finland-IP-04-2007

  35. Wi-Fi.Wi-Fi stands for "Wireless Fidelity" • The Wi-Fi technology allows completing mobile communications using radio waves. • Wi-Fi works with telephony by providing a wireless channel to the Internet. Wi-Fi converts voice and other data into radio signals that can be transmitted wirelessly. Internet-connected receivers then convert the radio signals into conventional data traffic that can be transmitted via the Internet or another network. Finland-IP-04-2007

  36. The sales of business-class Wi-Fi-based Internet phones increase about 120 percent from 2003 to 2004. There is a prediction that the Wi-Fi Internet telephony market will grow from $16.5 millions in 2002 to $500 millions by 2007. Finland-IP-04-2007

  38. The M-business main point The integration of the Internet technologies, the mobile communications and “online” business brought into the world a new child – the mobile business. Finland-IP-04-2007

  39. In Finland for example, the mobile trade is a part of the people daily round. For the Finn is a quite ordinary job to pay for the wash of his car, to buy beer from the automat or compact-disk, just pushing a few buttons of his mobile phone.In Norway the subscribers can see where the desired film is shown and can pay a ticket for it only using their phones.The Scandinavians that are familiar with the bitter cold weather can pay by their mobile phone not only their bus tickets but with its help they can understand when the bus is expected to arrive at the station. When the temperature is under minus 20 degrees such service is more than useful. Finland-IP-04-2007

  40. Definitions: 1. The M-business nature, in the most common way, can be defined as doing different business activities, using modern tools and methods of the information and communication technologies, especially mobile communication technologies and Internet. 2. Or M-business is the possibility to live and to work, having as a helper only mobile phone. Using WAP technology you can do shopping, arrange and conduct your business and leisure. 3. M-business includes the ability to perform business activities everywhere at every time without permanent physic connection to cable networks. Finland-IP-04-2007

  44. The mobile business possesses three specific characteristics: MNM – Mobility, Networking, and Monopoly. . Finland-IP-04-2007

  45. The mobility gives birth to unique benefits, connected with such aspects as: - Freedom of movement – you can use the services when you are on the road; - Ubiquity – it is not important where you are; - Accessibility – it can be confined to a given circle of people and/or given questions; - Localization – usage or accomplishment of services dependent on their concrete location. - Convenience – the mobile devices are always near at hand. Finland-IP-04-2007

  46. Networking is based on the fact that the networks are composed of components that are connected between each other and in practice each accomplished transaction between two of them has side effect over the other.The benefit of the share in a given network depends on the size and usually is double: direct, because the number of the potentially realizable connections increases, and indirect because with the increasing of the clients, the services become cheaper and highly varied. Finland-IP-04-2007

  47. Monopoly is connected with the availability of important credits that in practice are under the exceptional control of a given firm. The reasons for that are different: the absolute rarity of a given commodity or service, existence of a production secret, necessity of very high starting vested interests. Finland-IP-04-2007

  48. Basic services Finland-IP-04-2007

  49. Horizontal applications: -Sales Force Automation (SFA); -Client Relation Management (CRM); -Management of the accountancy and planning of the resources; -Accounting, logistics, accepting of orders; -Managing of warehouses; -Remote supply processing; - Inventory; -Access to the market and control of the trade activity, etc. Finland-IP-04-2007

  50. Vertical applications: Financial services in the pharmacy and medicine, the insurance business, the transport, journey and hotel services, telecommunications, government and military systems, manufacture and education(M-learning or U-learning); Real estate commerce;wood industry; Entrepreneurship and constructional supervision, forestry and wood economy.
