What is the sleep mode of a base station?
There are different stages of the sleep mode of base stations. These are mentioned below: On: the small cell operates fully and consumes the maximal power. Standby: the small cell sleeps in “light” mode and can easily wake up on UE's request., This can be done by shutting down the TCXO heater and RF.
Can unmanned aerial vehicles be used in cognitive radio?
gineering University of TrentoTrento, Italy [email protected]—Unmanned Aerial Vehicles (UAVs), which are at the forefront of cutting-edge technology, have unmat hed potential for pioneering applications in a wide range of disciplines. In particular, in the field of cognitive radio (CR), which is a ke
Can a wireless communication system become EE?
The extent to which a wireless communication system may become EE is heavily influenced by the parameter values that can be chosen in an application and the energy consumption modelling. Signal conditioning algorithms such as crest factor reduction and Digital Pre-Distortion are the two examples of improving PA .
Should EE be considered as a wireless network optimization topic?
The current wireless systems (such as 2 G, 3 G and 4 G) are intended primarily for maximum capacity and high data rates, therefore the term EE has not yet gained the required attention as a wireless network optimization topic.
