Overuse and relation to mental health BlackBerry thumb Driving safety Electronic waste External power supply Phantom vibration syndrome Radiation and health Recycling. Table I summarizes the results of these studies for reference.

Web surfing generates mostly downstream traffic, whereas mobile sensors generate traffic flowing mostly upstream. International Telecommunication Union. Please help improve this article by adding citations to reliable sources. The performance of radio communications depends on an antenna system, termed smart or intelligent antenna. The framework should be useful in exploring opportunities of mobile application development and guiding future research in this area.

The other important advantage of the above-mentioned access techniques is that they require less complexity for equalization at the receiver. This requires low-latency data transmission. Apps Development Distribution Management Cloud computing.

On the other hand, tolerating higher latency means that an otherwise perceptible delay has minimal effect on the operation of the application and user experience. However, in the context of mobile applications, the first two groups of requirements i.

His current interests are in telecommunications management, business data communications, and enterprise wireless networks. Because gaming feedback is also mostly touch based and requires quick response, light upstream traffic, and low latency are needed. Similarly, m-health applications can send collected video- or image-based medical data back to a repository for later assessment. An application that can tolerate higher latency typically does not require immediate feedback in the opposite direction. Such transmission requires heavy downstream traffic.

In the early s, to cater for the growing data rate needs of data communication, many transmission schemes were proposed. But most of them did not consider factors of technology. According to operators, a generation of the network refers to the deployment of a new non-backward-compatible technology.

Real-time, interactive applications require lower latency, whereas non-real-time applications can tolerate higher latency. Here it is assumed that real-time analysis or monitoring of data by software or human clinician is not required, hence medical data can be streamed back in a time-insensitive fashion. However, they require advanced dynamic channel allocation and adaptive traffic scheduling. In terms of form factor, it has an effect on how the mobile device is used. In addition to improvements in these multiplexing systems, improved modulation techniques are being used.

Such modality allows basic e-mail and some limited web surfing on a larger screen. Such context data is more important in indoor areas where location data e. List of mobile phone generations.

The research synthesizes network-related factors to generate the framework from a technology perspective. Journal of Communications.

This type of video conferencing not only allows collaboration anyplace anytime, but also permits the detection of visual cues e. Mobile Telephony Generations.

Please enter your email address. He has published articles in refereed journals and conference proceedings and is the author of three books on wireless communications. At the same time, allowing users to manipulate the virtual environment in real time requires quick response feedback and consequently low latency. Moreover, field personnel e. Coordinated Multi-point Transmission will also allow more system capacity to help handle the enhanced data speeds.

Instead, data can flow back to a central repository continuously, although not in real time. This section contains information of unclear or questionable importance or relevance to the article's subject matter. Summary of past literature on frameworks of mobile applications Text-based cellphone experience Large form factor Slow desktop e.

For researchers, the proposed framework can be used to guide future research in mobile applications running on emerging high-speed wireless networks and small form-factor devices. Second, html tags notes pdf the titles and abstracts of retrieve articles are examined to select those relevant to mobile application frameworks and high-speed wireless wide-area networks.
