    • 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:
    • u-Learning Tools QR Code Generators Quick-Response Codes can be read by mobile devices and provide instant links to text, websites, or other resources. http://www.qrstuff.com/ http://zxing.appspot.com/generator/ http://zxing.appspot.com/generator/ Try this one!
    • u-Learning Tools Mobl21 - A Mobile Learning Application Mobl21 helps educators easily create learning material, publish to multiple users or groups, and track and monitor content access and performances. http://www.mobl21.com/workflow/
