Wireless Communication
The attractiveness of mobile devices capability soon raises the number of cellular phones customers. This condition becomes issues for telecommunication companies and content providers to develop new killing applications besides voice communication that will increase the corporate revenue. The new application is data communication that comes in many forms.
Concerning the development of telecommunication technologies, this paper will discuss about the current state and probable futures of Wireless and Mobility. Some issues that will be addressed includes the evolving cellular technologies (2.5, 3rd 4th generation networks) disruptive technologies including WIFI (I.E.E.E.802.11), and WiMAX.
Literature Review Trends in Wireless Technology Mobility and Mobile Commerce
Telecommunications has become one industry that grows at a breakneck speed. In the 20th century, development that relates to communication businesses is simply unstoppable and unpredictable. Prior to the new millennium, total telecommunication revenues in United States alone were in excess of 260 billion. As we enter the new millennium, there were more than 100 million mobile wireless subscribers in the United States alone. The significant growth was contributed by new applications such as the wireless telephone and the internet (Mun, 2002).

In many cases, investing emerging technology can result great future benefits as the technology become the new platform of future communication products and services. The right choice of technology will create sustainable competitive advantage, first-to-market benefits, operational efficiencies, industry recognition, etc. one characteristic that is unquestionably important in the future of telecommunication is mobility. Figure 1 shows the growing number of mobile customers, which highlight the key features of telecommunication, is mobility. In addition, figure 2 shows several developments of technologies that highlight the mobility features.

Such development is attractive since telecommunication carriers are trying to increase customers usage on data communication into significant figure. There are various ways to reach the objective such as introducing several contents like mobile comics, games etc. Fortunately, the development of advanced 3G-based data services like cast by the famous NTT DoCoMo in Japan support the introduction of new applications such as mobile commerce (M-Commerce).

Figure 3 shows the popular Wi-Fi or hotspot area that can be established by individual users to connect to internet. Meanwhile Figure 4 shows that the needs for mobility features has spawn many inventions like Bluetooth, Wi-Fi that serves as wireless LAN etc. Wi_Fi itself come in many features each has specific characteristics such as maximum range, speed of transmission, that is why 802.11 technologies come in many standardization from 802.11a, 802.11b, to 802.11n (Evans, Martin, and Poatsy, 2010).

Fortunately, as telecommunication technology grows, some of the above technical problems can be alleviated in suitable manner. However, the others still become challenges that industry must deal with to speed up the technology adoption especially those relate to social and cultural issues.
Body Futures of Wireless Technology
Within the past few years, telecommunication industry starts looking at some emerging technologies that have potential to replace current technology. This is also important for corporations to find appropriate technology that has long lifetime so that the company can minimize replacement costs due to the equipments become obsolete before they reach their economical value. In addition, the future equipment should also capable of delivering various kinds of information that the company intends to deliver to customers (voice, data, and video).
Some technologies that might become concerns of company are WIMAX. Currently, WIMAX become the center of attention of most carriers worldwide due to their advantages over current access technology including 2G, 3G, xDSL, and Wi-Fi (Wireless FidelityHot Spot).
WIMAX stands for Worldwide Interoperability for Microwave Access is a broadband wireless technology that enables carriers like Indosat to provide end customers with direct high-speed connection up to 70 HYPERLINK httpen.wikipedia.orgwikiBits_per_second o Bits per second Mbits (shared data rates) within the range up to 50 km theoretically (non line of sight) although some vendors report that it reaches 30 km in range. The benefit of using WIMAX is their ability to complement with the existing network technologies (2G, 3G, and DSL).
In addition, WIMAX technology also offers customers with the benefits of wireless technology in which it enables customers to move from one apartment to another apartment as long as WIMAX signal covers it.

Conclusions
Globalization has brought new trends and new ways of doing business. Because of the internet and other telecommunication technology, people do not see distance the same way anymore. In the increasingly global business environments, e-commerce and e-business has been an increasingly common way of eliminating distance and expand market shares.
Concerning the development of telecommunication technologies, this paper has elaborated the discussion about the current state and probable futures of Wireless and Mobility. Some issues that will be addressed includes the evolving cellular technologies (2.5, 3rd 4th generation networks) disruptive technologies including WIFI (I.E.E.E.802.11), and WiMAX.
