Mobile Computing - Current Trends

This chapter lists the latest mobile technologies that are the hottest mobile technologies available on the market, beginning with 3G technologies.

3G

Mobile telecommunications 3G or 3rd generation is a generation of standards for cell phones and mobile telecommunications services that comply with the International Mobile Telecommunications 2000 (IMT-2000) criteria of the International Telecommunications Union. Wide-area wireless voice telecommunication, mobile Internet access, video calls and mobile TV are included in the application facilities, all in a mobile environment.

Global Positioning System (GPS)

The Global Positioning System (GPS) is a space-based satellite navigation system that provides location and time information in all weather, anywhere on or near the Earth, where there is an unobstructed line of sight to four or more GPS satellites. The GPS software offers essential capabilities for global military, civil and commercial users. In reality, GPS is the basis for modernizing the worldwide air traffic system, weather, and location services.

Long Term Evolution (LTE)

LTE is a high-speed data wireless communication standard for mobile phones and data terminals. It is based on the network technologies of GSM/EDGE and UMTS/HSPA, increasing power and speed using modern modulation techniques. It is associated with the launch of fourth generation (4G) technology.

WiMAX

WiMAX (Worldwide Interoperability for Microwave Access) is a standard for wireless communications intended to offer data rates of 30 to 40 megabits, with the most recent update providing fixed stations with up to 1 Gbit/s. It is part of the technology of fourth generation or 4G wireless communication. WiMAX far exceeds the traditional Wi-Fi Local Area Network's (LAN) 30-metre wireless range, providing a metropolitan area network with a signal radius of approximately 50 km. WiMAX provides data transfer rates that can be superior to traditional cable-modem and DSL connections, but multiple users must share the bandwidth and therefore produce slow temperatures in practice.

Near Field Communication

Near Field Communication (NFC) is a set of standards for smartphones and similar devices to establish radio communication with each other, typically no more than a few meters, by touching them together or bringing them near. Contactless transfers, data exchange, and simpler setup of more complex communications such as Wi-Fi involve existing and expected applications. Communication between an NFC device and an unpowered NFC chip, called a "tag," is also possible.

Conclusion

Computing today has evolved quickly from being confined to a single venue. With mobile computing, as long as the connection and security issues are properly considered, people can operate from the comfort of any place they want. In the same respect, the use of mobile computing has also been promoted by the presence of high-speed connections.

Mobile computing, as an ever-growing and evolving technology, will continue to be a core computing and information and communication technology service.
