Wireless system

This paper proposes using a non-linear system to generate chaos-based coefficient sequences applied in the sensor nodes of a landslide warning system. The experimental study demonstrated that the sensor node utilizing pseudo-random sampling is faster and less complex in comparison to the sensor node employing random sampling.

The third generation (3G) of mobile networks introduces wide spectrum and high data rates as well as variety of circuit-switched and packet-based services. It provides IP connectivity besides the circuit switching. Future generation mobile systems are expected to include heterogeneous access technologies, such as wireless LAN and 3G, as well as end-to-end IP connectivity (i.e., an all-IP network). The diversity of traffic services and access technologies creates new possibilities for both operators and users. On the other hand, it raises new traffic and design issues.

This paper proposes a dual-band PIFA antenna operated at 28/38 GHz for 5G communication systems. The PIFA antenna consists of two dielectric layers and an air gap is inserted between these two layers. Both substrates, namely Roger RT dielectric, have a relative dielectric constant of 2.2 and a thickness of 0.127 mm.
