Designed to carry communications payloads during natural disasters, the drone could act as a local satellite, allowing high-speed data transmission until area infrastructure gets repaired.
The feasibility of using cellular phones (StarTac 7868, Motorola) in data transmission in the area not covered by the WLAN was also tested.
The way of data transmission on a controller area network (CAN) bus and wireless data transmission mode is explained.
Finally, among the divided quadrant zones, the slave CH is selected according to the higher moment to help the master CH optimize data transmission in the local area.
It discusses topics, such as the basics of wireless communications, modulation schemes used in digital data transmission, basics of wireless local area networks, the IEEE 802.11, the workings of digital radios, radio signal transmission and reception by means of antennas, problems related to radio signal transmission and methods to overcome them, and outdoor microwave links.
Wireless communications are developing very fast in order to adapt with the increasing demand for high-speed and reliable data transmission over a wide coverage area.
Meanwhile, Ericsson's plain old telephone service core is still losing money, a victim of price-cutting and the fact that Ericsson has very little to offer in the vital area of data transmission.
With data transmission, the data leave the area of control by a specific user, which may have implications on privacy and security (see below).
Based on the data success probabilities, the optimal time allocation between the wireless EH and data transmission is investigated through maximizing the area throughput of both the non-cooperative and cooperative systems.
The proposed algorithm proceeds as follows: when a mobile user moves within the Wi-Fi coverage area and starts data transmission, the data will be queued in OpenFlow switch and awaits further processing.
