Diffusion and competition of voice communication technologies in the Czech and Slovak Republics, 1948–2009

In order to meet the ever increasing demand by people using mobile technology and its associated services based on multimedia elements in addition to voice, mobile communication technologies has since evolved from analog to digital and 1G to 4G. This chapter presents a contemporary review of all generations of mobile communication technologies, including their standards. 1G to 3G mobile communication technologies are mainly optimised for voice communication, using circuit switched networks. To provide high transmission mobile services at low cost in all levels of networks—personal, home, and cellular—it is imminent to exploit the merits of all existing technologies such as Bluetooth, WLAN, and HiperLAN, and use IP as a backbone network in 4G mobile communication standards. The key research challenges for mobile terminals, systems, and services for 4G networks are also presented in this chapter.

Communication Needs

People with ASD often need to access AAC in situations where a tabletop digital device is not practical. Recent advancements have made more powerful, portable, and affordable communication technologies available to these individuals. Proloquo2Go is a new portable augmentative and alternative communication system that runs on an iPhone or iPod touch and can be used to meet the diverse needs of individuals with autism spectrum disorders (ASD) who are ambulatory and have difficulty using speech to meet their full daily communication needs. This article examines Proloquo2Go in light of the best practices in AAC for individuals with ASD such as symbols, visual supports, voice output, and inclusion.
