Simply put, if the internet gave us the ability to access any web address on a desktop, mobiles have given us the access at any time and from anywhere. This capability, derived from modern telecommunication technology, is crucial in conducting international business operations. Nevertheless, due to various mobile protocols and networks available in different parts of the world nowadays, for example, analogue, GSM, TDMA or CDMA, it becomes challenging for the airtime providers to expand their services across technological incompatibility. The developing Third-Generation (3G) standard is attempting to unify all new-generation mobile devices in a single platform. With the new standard, the mobile gadgets may replace desktop PCs, laptop PCs, credit cards or even wallets in the near future! [1]
2 Why go mobile Mobile communication allows people to stay in touch with each other at anytime, almost anywhere and through handheld devices. Unconstrained by wires, mobile-system users can communicate while travelling as fast as about 60 miles (100 km)per hour The mobile phone converts the speaker's voice into radio waves that travel through the air until they reach a receiver at a nearby base station. The base station then sends the call through the telephone network to the intended recipient. The initial impetus for developing and marketing mobile telecommunications systems was to offer consumers mobility. At first, many consumers were not enticed by this capability due to its higher cost compared with fixed lines. However, that difference declining as companies create national or regional networks and alliances that offer pricing plans without roaming fees(charges for calls outside the carriers service area Unlike most countries in the world, in the USA, mobile phone users incur charges, whether the call is incoming or outgoing, thus bearing higher total cost. The full-feature capabilities of digital phones along with declining service charges have reduced the importance of pagers in the wireless industry.

There have been a number of satellite operators like the examples given above who eventually went bankrupt due to lower incomes than expectations. The reasons for this hip can be described by the following: the satellite industry has a long wait between design and profitability, i. e. it can make money only after 10 years in orbit and needs to build the entire network before signing up its first customer manufacturers must lock down technology more than 3 years before launches the industry bets on a market up to 15 years. These are the major negative factors most satellite communication providers are encountering nowadays. Some analysts still see good opportunities for this industry, for example, Futron [10], a technology management consulting firm based in Maryland predicts that the satellite transponder business will grow more than 75% within 10 years from now. This would be a good opportunity for satellite operators to turn to focus on video/audio and broadband markets rather than sticking to only the voice market, which forecasted to stay flat for the coming decade. 3. 2.

It can handle wireless phone calls, hold addresses and take voice mail and can also access information on the internet and send and receive e-mail and fax transmissions. It can be viewed as a combination of a mobile phone and a PDA in a single gear. • PC Tablet. A new generation of slate-style portable computers from Microsoft and its partners promise to combine the flexibility of paper notepads with the best attributes of powerful notebook PCs. Microsoft has added a program called Microsoft Journal, which is intended to be a note-taking replacement for the pad of paper you would typically take to a meeting. Everything you write on the pad is stored as graphics – called digital ink – unless you highlight an area and ask the machine to recognise what you wrote. PC makers working on Windows XP Tablet PCs include Acer, Compaq, Fujitsu, Tatung and Toshiba
Mobile communications: global trends in the 21st century Pager. A small telecommunications device that receives(and, in some cases, transmits)alert signals and/or short messages. This type of device is convenient for people expecting telephone calls but who are not near a telephone set to make or return calls immediately. It is estimated that there will be 260 million pager users worldwide by 2003. The overall market revenue for paging/messaging is predicted to be S11.92 billion in 2005 (Wireless Week, The Future of Paging, Oct 1999)[12] 3.2.2 Wireless computing Wireless computing or Wireless Local Area Network (WLAN) is the technology that enables a user to receive information such as e-mails and files directly from the internet or any networks to one's laptop, without the sender's knowledge of the serving network IP address, which may be a wireless LAN. The technology allows for the rerouting of information to the served network for wireless computing just as it does for mobile data services based on 2.5G and 3G technologies For this application, there are two competing technologies in this field; Bluetooth and Bluetooth. An open specification for seamless wireless short-range(less than 30 feet) communications of data and voice between both mobile and stationary devices For instance, it specifies how mobile phones, computers and PDAs interconnect with each other, with computers, and with office or home phones. The first generation of Bluetooth permits exchange of data up to a rate of 1 Mbps, even in areas with a large amount of electromagnetic disturbanc Wi-Fi(802. 11b) Provides for wireless Ethernet transmission primarily between aptos or PDAs and local access nodes that attach to a standard corporate Lan Todays 802. 1lb products transmit in the unlicensed spectrum at 2.5 GHz, and are capable of speeds of up to 11 Mbps. This standard, despite higher speed, is not litable for mobile applications or moving devices 3.2.3 M-commerce M-Commerce is the use of radio-based wireless devices such as cell phones and PDAs to conduct business-to-business and business-to-consumer transactions over wired web-based e-commerce systems [13]. This application should be seen as a complement of existing e-commerce, which focuses on different groups of customers. Nowadays, we might see examples of m-commerce in forms of m-banking, m-payment and latest, e-vending[14

The technology allows for the rerouting of information to the served network for wireless computing just as it does for mobile data services based on 2.5G and 3G technologies. For this application, there are two competing technologies in this field; Bluetooth and 802.11b or Wi-Fi: • Bluetooth. An open specification for seamless wireless short-range (less than 30 feet) communications of data and voice between both mobile and stationary devices. For instance, it specifies how mobile phones, computers and PDAs interconnect with each other, with computers, and with office or home phones. The first generation of Bluetooth permits exchange of data up to a rate of 1 Mbps, even in areas with a large amount of electromagnetic disturbance. • Wi-Fi (802.11b). Provides for wireless Ethernet transmission primarily between laptops or PDAs and local access nodes that attach to a standard corporate LAN. Today’s 802.11b products transmit in the unlicensed spectrum at 2.5 GHz, and are capable of speeds of up to 11 Mbps. This standard, despite higher speed, is not suitable for mobile applications or moving devices. 3.2.3 M-commerce M-Commerce is the use of radio-based wireless devices such as cell phones and PDAs to conduct business-to-business and business-to-consumer transactions over wired, web-based e-commerce systems [13].
