Solar powered mobile telephony
Proceedings Second International Symposium on Environmentally Conscious Design and Inverse Manufacturing, 2002Sustainable development will require replacement of older technologies and increased use of both renewable energy and telecommunications. The world-leading tele- and data-communications systems supplier, Ericsson, is increasingly offering solar powered solutions.

Improving mobile video telephony
2014 Eleventh Annual IEEE International Conference on Sensing, Communication, and Networking (SECON), 2014Video telephony is becoming popular over smart-phones and tablets. Unlike the Desktop era, smartphone users are often ‘mobile’ and this impacts how the video is processed and transmitted over the network. The significant increase in the motion content in such videos change the composition of video frames.

A mobile telephone system is defined as a communication network via radio which allows continuous mobility by dividing its coverage area into cells. Wireless communications, on the other hand, imply radio communications without necessarily requiring handover from one cell to another during an ongoing call (Nanda and Goodman 1992).

Mobile IP telephony: mobility support of SIP
Proceedings Eight International Conference on Computer Communications and Networks (Cat. No.99EX370), 2003The Internet has recently become the most important, most popular way of communication. A significant new feature of the Internet is the support of telephony. Two main competing signaling protocol standards have been developed for this purpose: H.323, proposed by the ITU, and SIP, proposed by the IETF.

Servuction and Mobile Telephony
The Service Industries Journal, 1999Because mobile telephony develops oral communication between a service provider and its customers and between the different employees in the firm, irrespective of the physical location of the actors, it makes the role of oral interaction in servuction more dynamic. Considered an innovation which necessarily undergoes an iterative process of integration,

Testbed for Mobile Telephony Networks
2011 Sixth International Conference on Availability, Reliability and Security, 2011Mobile telephony and mobile communication are both crucial and critical infrastructures for today's society and contribute to its security and safety. In contrast to landline telephony with its physically protectable medium, mobile telephony utilizes air and electromagnetic waves as communication medium, which cannot be easily protected.

Signaling Attacks in Mobile Telephony
Proceedings of the 11th International Conference on Security and Cryptography, 2014Mobile telephony based on UMTS uses finite-state control schemes for wireless channels and for signaling across the network. These schemes are used systematically in various phases of the communication and are vulnerable to attacks that can bring down the network through unjustified bandwidth allocation and excessive signaling across the control plane.

Physics and biology of mobile telephony
The Lancet, 2000Although safety guidelines--to which mobile telephones and their base-stations conform--do protect against excessive microwave heating, there is evidence that the low intensity, pulsed radiation currently used can exert subtle non-thermal influences. If these influences entail adverse health consequences, current guidelines would be inadequate.

Clatter diminishing for mobile telephony
2015 International Conference on Innovations in Information, Embedded and Communication Systems (ICIIECS), 2015This paper discusses about the application of denoising process for mobile phones. Mobile phones are often used in noisy environments such as noisy street, cafe, or in a moving car/train. The attribute of speech can be degraded by the background noise.
