On Deployment Position of RIS in Wireless Communication
Abstract: A reconfigurable intelligent surface (RIS) is capable of altering the wireless channel and thus can assist wireless transmission where the direct path is blocked. The deployment
How to determine signal strength verses distance for LTE base stations? All mobile phones have bars or some other type of indicator displaying signal strength. As mobile devices move away from the base station the signal strength becomes weak and at some point becomes out of range or establishes connections with a different tower.
Base stations are important in the cellular communication as it facilitate seamless communication between mobile devices and the network communication. The demand for efficient data transmission are increased as we are advancing towards new technologies such as 5G and other data intensive applications.
The base station's RF circuitry is housed in a small outdoor module known as a remote radio head (RRH) or remote radio unit (RRU). RRH performs all RF functions such as transmit and receive functionality, filtering and amplification. It also has analog-to-digital or digital to analog and digital upconverters.
