Transmitting information over the electromagnetic spectrum involves a combination of technologies, techniques, and protocols that deal with encoding digital information onto a carrier frequency, combining multiple carriers into a channel, and sharing the channel with multiple users.
As demands for higher data throughput continue to increase, RF systems have become increasingly more complex over time. New MIMO techniques have evolved, using multiple antennas to communicate over multiple streams within the same carrier. With the increasing need to pack more transmitters into the same geographical area, modern wireless networks implement a range of Advanced Antenna System techniques such as beamforming and band steering.
Each transmission technique deals with a unique challenge in the communication of digital information. If you are familiar with digital signalling such as those involved in traditional wired communications, you'll recognise that many signalling techniques are no different. You can learn more about each technique by following its heading below.
We stand on the brink of a technological revolution that will fundamentally alter the way we live and work. The possibilities of billions of people across the globe connected by mobile devices, with unprecedented processing power and access to knowledge, are unlimited. Technological innovation remains the single most important driver of economic prosperity; it alone has the power to raise global living standards through increased efficiencies. Powertec are proud to contribute to the Fourth ...
The topics below each serve as a technical reference for the foundational principles and technologies essential for understanding wireless communication systems. You will find information pertaining to spectrum management, transmission techniques, security protocols, and the structural frameworks of networks. Each section breaks down the different schemes, techniques, protocols, and bands in a list format for easy reference.
