  • Industry White Paper for Construction
    Industry White Paper for Construction Anyone in the construction industry can appreciate how instant communication keeps projects on time and on budget. It’s why the construction industry was one of the earliest adopters of push-to-talk (PTT) technologies on mobile phones. However, as mobile technology has moved forward, PTT has been stuck in the past. That is, until now. Voxer brings push-to-talk into the modern age, is available for most smartphones, and gives more capability and flexibility than any other instant communication solution on the market. How can Voxer help construction crews? ‣ Turn your smartphone into a walkie-talkie - stream audio from your phone even when you’re out of the app ‣ Eliminate range problems - get broader coverage with voice communication that works on any 2G, 3G, 4G or WiFi network ‣ Broadcast information quickly - create team contacts for one-touch communication to large groups of workers ‣ Never miss a message - live and recorded audio coupled with loud, repetitive alerts ensures that nothing is lost ‣ Keep in touch from your desktop - use a web browser to listen and respond to multiple conversations at a time 1 Problems with Traditional Push-to-Talk The core functionality of PTT is incredibly useful, however its live-only state ofers limited capability. When communication is “live-only” (e.g. two-way radios, cell phone PTT, phone calls) everyone is continuously interrupted, and if an employee is unavailable, important information can be lost and huge delays are possible. Traditional push-to-talk also requires expensive hardware that’s often outdated. Radios can cost hundreds or thousands of dollars a piece and have extended costs associated with maintenance.

  • The Impact of Mobile Technology on Teaching and Learning in the Undergraduate Population Patrick Davis
    The Impact of Mobile Technology on Teaching and Learning in the Undergraduate Population Patrick Davis 2014 Maxine Smith Fellowship Introduction: On‐Demand Learning Increasing access, limiting cost, and sustaining quality standards delineate an intolerable wish list, given the level of inconsistency among these drivers. The solution in many cases has been introducing exclusivity to post-secondary education through narrowing paths for learners. The marketplace for mobile devices (tablets, smartphones, e-Readers, etc.) is varying and developing precipitously, conveying with it new devices, new standards and new opportunities around mobile capabilities. For higher education institutions that want to facilitate learning on mobile devices, these changes will continue to have a substantial influence on these efforts. This paper highlights mobile strategic planning, partnering with vendors, the results of a mobilization survey given to the Maxine Smith Fellow 2014 class, and recommendation for uses of mobile technology. Overview of TBR Strategic Plan for Mobilization The use of mobile technologies has grown to such an extent over recent years that they now overtake the proliferation of personal computers in modern professional and social contexts (Attewell, 2005). The ready availability and uptake of devices such as mobile phones, personal digital assistants and mobile music players, have permeated the manner and means of human communication, socializing and entertainment to such an extent that is it rare to find a person in western society who does not own at least one such device. And yet, the pedagogical use of these powerful devices is not widespread in higher education. Notwithstanding the reality of the ‘digital divide’, the declining cost and mounting social currency associated with mobile devices, means that many students own one or more such devices.

  • Improving M-Examination Results System Using Multimedia Messaging Service
    World Applied Sciences Journal 14 (11): 1620-1627, 2011 ISSN 1818-4952 © IDOSI Publications, 2011 Improving m-Examination Results System Using Multimedia Messaging Service Mohd Hilmi Hasan, Nazleeni Samiha Haron, Nur Syafiqah Syazwani Md Yazid Computer and Information Sciences Department, Universiti Teknologi PETRONAS, Bandar Seri Iskandar, 31750 Tronoh, Perak, Malaysia Abstract: Mobile devices are becoming more important in daily lives for not just making phone calls, but also for information gathering, personal management and entertainment. They have also gained an increasing demand in education field, for instance m-learning, mobile time table system and many others. The objective of this paper is to present the improvement of current m-examination results systems that send results via SMS. The system was developed in 3-tier architecture and tested by 35 respondents in which it accepts request from student in SMS, does information searching, converts information into PDF document and sends the document to student via MMS. Two types of tests were conducted to evaluate the system namely functional and user acceptance tests. The system was successfully developed and believed can improve the SMS-based examination results system. The study implies potential time saving where MMS-based examination results slip can be used for official transactions on top of its flexibility that is accessible anytime and anywhere. For future works, it is proposed that more security measures be implemented to ensure reliability and both MMS-based and SMS-based functionalities are integrated in a single system to offer more benefits to users. Key words: MMS SMS MMS-based system SMS-based system Examination results retrieval INTRODUCTION system.

They have been designed for readers who don’t have a technical background in the subject. While this is only a very brief introduction to the subject, these handbooks should hopefully provide a useful overview. 4 The titles in this series are: Introducing radio spectrum Introducing spectrum management Managing spectrum for growing data The spectrum policy dictionary 5 1G The first generation of ‘cellular’ mobile phone systems used in the late 1970s until the early 1990s. These analogue-based systems were replaced by 2G digital mobile systems - most notably GSM. Examples include AMPS (Advanced Mobile Phone System), NMTS (Nordic Telecommunication System) and TACS (Total Access Communications). 2G The second generation of ‘cellular’ mobile phone systems which appeared in the 1990s were the first to employ digital coding. The vast majority of 2G mobile networks around the world use GSM technology. However, there are other 2G systems including D-AMPs, PDC, iDEN and most notably cdmaOne which continues to be used by some operators around the world. 2.5G see GPRS 2.75G see EDGE 3G The third generation of ‘cellular’ mobile phone systems were the first to be designed from the outset to support high speed data services as well as voice. The most dominant system used is WCDMA which was deployed by the operators which previously used GSM. However, other systems are used including CDMA2000 (largely by operators that previously used cdmaOne) and the Chinese system TD-SCDMA.
