When a UAV employs radio of such a high-frequency band, the available communication time can be less than one second, and the feasibility of leveraging this ultra-narrow zone, which is only accessible for a short duration in a confined space, has not been investigated. This paper ...
There are many numbers of the parameters which handles transmission rate, transmission power, etc. The data transmission time also impacts on the energy conservation and quality-of-service (QOS) in wireless sensor network. 展开 关键词: data communication energy conservation quality of service radio ...
Emerging demands for high data rate services and high spectral efficiency are the key driving forces for the con-tinued technology evolution in wireless communications. Third generation (3G) mobile communication systems have already been commercially deployed in certain parts of the world to meet the...

The fourth generation wireless communication (4G) systems have been deployed or are soon to be deployed in many countries. However, with an explosion of wireless mobile devices and services, there are still some challenges that cannot be accommodated even by 4G, such as the spectrum crises and ...
Today it is an open question how we can realize a wireless system at this speed. If we intend to use such systems in a mobile environment, we can only afford to spend approximately 110 pW/b for the end-to-end communication. This includes RF-transmission and all processing and protocol ...
The technology was given a major boost with last year’s release of the IEEE 802.11bb standard that defined wireless light-based communications, especially as bandwidth congestion inspires a search for alternative transmission solutions. Visible Light Communication, as the LiFi industry group has dubbed...
