Definition / Scope
4G is also known as the 'Fourth Generation' of mobile communication. 4G is the upgraded version of 3G which also guarantees greater speed and performance.
With these features, users have access to various services, increased coverage, and convenience of a single device, more reliable wireless access even with failures or loss of one or more networks.
4G uses the Multiple Input Multiple Output Technology that uses signal multiplexing between several transmitting antennas and time or frequency.
In line with that, 4G technology can be integrated with existing platforms (towers and available antennae) quite adeptly, thus eliminating new hardware investment costs.
However, with the operation of 4G, the problem of availability of network esp. in remote places would become more than protruding as this technology is far more advanced than the previous standards.
Major Requirement and solutions for management of 4G include:
- Seamless handoff: The handoff operation should be quick so that handoff latency is less in order to reduce packet drop as much as possible.
- Signalling traffic overhead: The number of signalling packets to the related databases must be minimized to avoid load to network.
- Quality of Service (QoS): The mobility management scheme should support establishment of new QoS reservation in order to deliver maximum traffic but reduce the disruptive effect.
- Fast Security: Different levels of security must be supported such as data encryption and user authentication while limiting the traffic and time of security process
- Bandwidth: Higher bandwidth ranges assure lower call dropping and call blocking probabilities.
- Power Consumption: The issue of power saving arises in new network discovery because unnecessary interface activation can increase power consumption. It is also important to incorporate power consumption factor during handoff decision.
- User Preferences: It could be preferred networks, user application requirements in real- or non-real time, different types of services such as video, voice and data, quality of service among others.
