The mobile computing industry consists of all entities that play a role in enabling wireless connectivity. It includes manufacturers of mobile computing devices who produce different items such as laptops, notebook PCs, tablet PCs, palmtops, personal digital assistant (PDAs) and other hand held devices.
It consists of Wi-Fi(wireless fidelity) network service providers who provide wireless network coverage to offices, public places, and other small workplaces. They use a wireless access point device to provide wire free network coverage in the designated area. They use 802.11b and 802.11a IEEE(Institute of Electrical and Electronics Engineers) standard access point devices to transmit data at 2.4 GHz and 5 GHz respectively.
Some service provides use WiMax (Wireless Interoperability for Microwave Access) technology to provide network coverage over a large area. It can transmit data up to a distance of forty-eight km and provides a maximum networking speed of seventy Mbps. It is better than Wi-Fi as it provides higher bandwidth and high data security by using enhanced encryption schemes. WiMax supports several communication protocols, and can act as the backbone network for an ISP(Internet service provider) as well as telecom service provider.
The software industry also contributes to the mobile computing industry by developing mobile computing software. People use the software to access the Internet, send and receive e-mails, and download electronic content. Users can work on windows word document, excel spreadsheets, and make audio/video presentations using Microsoft PowerPoint. They can draw images and write text messages in devices that use touch screens and digital pens. It can also be used to download audio files such as mp3.
Mobile computing industry has witnessed a respectable growth in recent years due to the demand for mobile computing devices. The industry is currently working on nano technology to develop new devices that will be small enough to fit a wristwatch and operate much faster than current generation mobile computing devices.
