3. 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
4. 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
5. 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)
6. 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.
7. 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.
8. 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.
9. Implications for u-Learning
Educators must keep pace with the continued
advances in wireless technology and the growing
popularity of mobile devices.
