If nothing else, it serves to illustrate an important point: it takes roughly a decade from the first specification of a new wireless standard to its mainstream availability in real-world wireless networks. By extension, it is a fairly safe bet that we will be talking about LTE-Advanced in earnest by the early s! Unfortunately, deploying new radio infrastructure is a costly and time-consuming proposition.
Ironically, while 4G networks provide significant improvements for IP data delivery, 3G networks are still much more efficient in handling the old-fashioned voice traffic! Voice over LTE VoLTE is currently in active development and aims to enable efficient and reliable voice over 4G, but most current 4G deployments still rely on the older, circuit-switched infrastructure for voice delivery.
The RRC lives within the radio network. In 2G and 3G networks, the RRC lived in the core carrier network, and in 4G the RRC logic has been moved directly to the serving radio tower eNodeB to improve performance and reduce coordination latency. However, even though LTE offers a theoretically higher degree of power control, the radios themselves tend to consume more power in LTE devices; higher throughput comes at a cost of increased battery consumption. Uses three-radio technology and small-angle antennas to provide Wi-Fi coverage in high-density settings like stadiums and hotels.

Access Controllers. Most of this traffic will originate from high throughput services , such as virtual reality and ultra-high definition video streaming. These three trends result in several important challenges for the wireless networks of the future:. To support future high-throughput services, a range of different wireless network technologies are being developed for mobile communications e. Moreover, on the longer term terahertz and optical wireless technologies, using visual e. These new technologies bring several new features, such as multi-user and massive MIMO, as well as beam steering and forming.
Design And Performance Of 3g Wireless Networks And Wireless Lans
Although these technologies and their features promise immense improvements in terms of scalability and throughput, state of the art data link, network and transport layer protocols are not adapted to bring out their full potential. IDLab performs cutting edge research to address this issue, and brings future network protocols in line with the hardware and physical layer features offered by state of the art network technologies.
Research on the following topics is performed:. These three trends result in several important challenges for the wireless networks of the future: Ultra-high throughput : Current 4K and Ultra-High Definition streaming services already require up to around 25Mbps per stream.
- Digital Logic Testing and Simulation, Second Edition;
- Building Interactive Worlds in 3D: Virtual Sets and Pre-visualization for Games, Film & the Web!
This is only expected to further increase exponentially, especially with the advent of new types of content and services, such as virtual reality and 3D video. Seamless mobility : Users with mobile devices want to enjoy uninterrupted service while moving around, both in their homes, but also while traveling using their car or public transportation.
