And Its Implications for Ubiquitous Learning by Tiffani Pittman
What is 4G? 4G is the Fourth Generation of Mobile Technology 4G is still in the development stages The “New 4G Phones” are actually using what should be termed 3.5G or 3.75G
What do we have now? Advertisers promoting 4G services currently employ the following technologies: HSPA+ (T-Mobile) WiMAX (Sprint) LTE (Verizon) “True 4G” Technologies include LTE-Advanced (Long Term Evolution Advanced) and WiMAX Release 2, neither of which are available today
4G Standards? The International Telecommunications Union (ITU) set the following requirements (among others) for the technology to be considered True 4G: All-IP packet switched network Data rates up to 100 Mbps for high mobility and up to 1 Gbps for low mobility Seamless connectivity and global roaming Interoperability with existing wireless standards Smooth handovers High QoS (Quality of Service)
What will 4G do? 4G will be extremely fast. Download speeds of 100 Mbps when you’re moving and 1 Gbps when you’re stationary far surpass today’s maximum speeds (which are 10 to 20 Mbps for the new “4G” phones). 4G operates on a greater number of frequency bands at lower signals, which will provide broader coverage at a lower cost than traditional services. 4G will provide seamless global connectivity, while the multiple standards used for 3G technologies make it difficult to interoperate across networks. 4G will provide higher levels of security and standards.
Implications for u-Learning Smart phones and devices are affordable and widely used, providing 24/7 connectivity to a large portion of the population, spreading the opportunities for u-learning. 4G technologies will allow seamless transitions between devices including our mobile device, laptop, e-reader and TV, so that u-learning can be delivered and continued whenever and wherever we are. Mobile device upgrades, including larger screens, improved camera technologies and longer battery lives, will enhance u-learning experiences.
Implications for u-Learning 4G will help bring broadband access to rural and developing areas where landlines are not available, bringing educational opportunities to those areas. Mobile technology improvements have spurred an increase in flexible and functional authoring systems, allowing for easier cross- platform content development. With increased download speeds, richer interactive experiences will be available for mobile devices, particularly streaming audio and video for web conferencing and new forms of proximity computing.
Implications for u-Learning Educators must keep pace with the continued advances in wireless technology and the growing popularity of mobile devices. Get started today with tools like the following:
