Complete hyperbolic lattices derived from tessellations of type {4g,4g}
Journal of Algebra and Its Applications, 2016Regular tessellations of the hyperbolic plane play an important role in the design of signal constellations for digital communication systems. Self-dual tessellations of type [Formula: see text] with [Formula: see text], and [Formula: see text] have been considered where the corresponding arithmetic Fuchsian groups are derived from quaternion orders ...

Moving Towards Mmwave-Based Beyond-4G (B-4G) Technology
2013 IEEE 77th Vehicular Technology Conference (VTC Spring), 2013Availability of large untapped spectrum resources in the millimeter wave (Mmwave) band is suitable for providing a gigabit experience with true local feel using high capacity small cells. Unlike traditional cellular systems, millimeter wave transmissions do not benefit from diffraction and dispersion making it difficult for them to propagate around ...

Have you ever called your cellphone carrier to report poor signal strength? Sure you have. And did that carrier do anything significant to fix the problem? Of course it didn't - unless you live in South Korea. LTE-Advanced mobile technologies will bring more network capacity, faster data speeds, and better coverage.

Fourth generation (4G) wireless networks aim at supporting various multiservice applications over IP architectures which satisfy enhanced users demands through innovative services of increased Quality of Service (QoS). QoS can be assured through independent optimal design of network components or by optimizing interoperability.
