Contents • What Is M-Commerce? • Why Wireless? • Critical Success Factors • How Wireless Technology Is Employed • Wireless LAN • Wireless Application Protocol (WAP) • Implications for Management
Introduction • Wireless Technology is all things to all people • People are searching for ways to keep in touch with anyone, anywhere, at any time • In business wireless technology is necessary • The term wireless mean transmitting signals over radio waves instead of wires • It also mean data communication without physical attachments using • Microwave • Radio wave • infrared
Introduction • Mobile phones are wireless • People use mobile to ( business ) • Check e-mail • Shop on the Internet • Yet it is a problem doing business via mobile • Limited interface • technical problems • Security problems
Introduction • Wireless networks are just effective as wired system • Wireless networks • Easy to install • Easy to operate • Eliminate the cost of cabling
Mobile Commerce: Overview • Mobile commerce (m-commerce, m-business)—anye-commerce done in a wireless environment, especially via the Internet • Can be done via the Internet, private communication lines, smart cards, etc. • Creates opportunity to deliver new services to existing customers and to attract new ones
What Is M-Commerce? • M-commerce is the transmission of user data without wires • It also refers to business transactions and payments conducted in a non-PC-based environment • Focus on services and applications on the mobile phone is what m-commerce all about • Message from one person to another is not m-commerce • But message from ISP to a person is m-commerce
What Is M-Commerce? • M-commerce:- use of wireless devices to facilitate the sale of products and services, anytime, anywhere • M-commerce is not about selling products and services on a mobile devices, they are part of m-commerce
What Is M-Commerce? • The main categories are: • Information based • Searching web for information • Sending e-mail • Transaction services • Download information • Make purchases by a cellular phone • Location-centric • Personalized services that anticipate your purchases based on your location and data stored in your profile
m-commerce and e-commerce • Physical size (PC versus mobile device) • Bandwidth • PC-oriented e-commerce employs HTML technology while m-commerce and the wireless web use two distinct development languages wireless Mark-up language (WML) and Handheld Device Mark-up Language (HDML) which require different browser loaded into mobile phone
Why Wireless? • It traces its roots to the invention of the radio back in 1894 • Wireless networking makes it possible to connect two or more computers without the bulky cables, giving the benefits of a network with little or no labor
M-Commerce Terminology • Generations • 1G: 1979-1992 wireless technology • 2G: current wireless technology; mainly accommodates text • 2.5G: interim technology accommodates graphics • 3G: 3rd generation technology (2001-2005) supports rich media (video clips) • 4G: will provide faster multimedia display (2006-2010)
Wireless Technologies • Wireless devices are small enough to easily carry or wear, have sufficient computing power to perform productive tasks and can communicate wirelessly with the Internet and other devices. • Include PDAs, cellular phones, smart phones. • Wireless Application Protocol (WAP) is the standard that enables wireless devices with tiny display screens, low bandwidth connections and minimal memory to access Web-based information and services.
Wireless Technologies • Microbrowsers are • Internet browsers with a small file size • can work within low-memory constraints of wireless devices and the low bandwidths of wireless networks. • Pager is a one-way, wireless messaging system; it alerts the user when it receives an incoming message.
Terminology and Standards • GPS: Satellite-based Global Positioning System • PDA: Personal Digital Assistant—handheld wireless computer • SMS: Short Message Service • EMS: Enhanced Messaging Service • MMS: Multimedia Messaging Service • WAP: Wireless Application Protocol • Smartphones—Internet-enabled cell phones with attached applications
Attributes of M-Commerce and Its Economic Advantages • Mobility—users carry cell phones or other mobile devices • Broad reach—people can be reached at any time • Ubiquity—easier information access in real-time • Convenience—devices that store data and have Internet, intranet, extranet connections • Instant connectivity—easy and quick connection to Internet, intranets, other mobile devices, databases • Personalization—preparation of information for individual consumers • Localization of products and services—knowing where the user is located at any given time and match service to them
Key Limitations Wireless limitations address: • Distance • Speed • The speed of wireless network is one-ninth the speed of wired network • Crawling pornography • Security and security factors Tracking users is the number one privacy concern
Critical Success Factors In m-commerce, four critical success factors need to be monitored: • Mobility • Personalization • Global standardization • Customer profiling
Mobile Computing Infrastructure • Hardware • Cellular (mobile) phones • Attachable keyboard • PDAs • Interactive pagers • Other devices • Notebooks • Handhelds • Smartpads • Screenphones—a telephone equipped with color screen, keyboard, e-mail, and Internet capabilities • E-mail handhelds
Mobile Computing Infrastructure(cont.) • Unseen infrastructure requirements • Suitably configured wireless WAN modem • Web server with wireless support • Application or database server • Large enterprise application server • GPS locator used to determine the location of mobile computing device carrier
Mobile Computing Infrastructure (cont.) • Software • Microbrowser • Mobile client operating system (OS) • Bluetooth—a chip technology that enables voice and data communications between wireless devices over short-range radio frequency (RF) • Mobile application user interface • Back-end legacy application software • Application middleware • Wireless middleware
Mobile Computing Infrastructure (cont.) • Networks and access • Wireless transmission media • Microwave • Satellites • Radio • Infrared • Cellular radio technology • Wireless systems
Limitations of M-Commerce • Usability Problem • small size of mobile devices (screens, keyboards, etc) • limited storage capacity of devices • hard to browse sites • Technical Limitations • lack of a standardized security protocol • insufficient bandwidth
Limitations of M-Commerce • Technical Limitations… • transmission and power consumption limitations • poor reception in tunnels and certain buildings • multipath interference, weather, and terrain problems and distance-limited connections • WAP Limitations • Speed • Cost • Accessibility
Limiting technological factors • Networks • Bandwidth • Interoperability • Cell Range • Roaming • Mobile Middleware • Standards • Distribution • Localisation • Upgrade of Network • Upgrade of Mobile • Devices • Precision • Mobile Devices • Battery • Memory • CPU • Display Size • Security • Mobile Device • Network • Gateway
