How Important Is mmWave To 5G?

For 5G to deliver high expectations, it must operate across wide contiguous frequency spectrum - only available at mmW frequencies. The frequency bands in the spectrum above 24 GHz can support large bandwidths and high data rates, ideal for increasing the capacity of wireless networks. Anokiwave offers the industry's most complete portfolio of Silicon ICs for mmW 5G and is the trusted choice of Tier-1 and -2 OEMs worldwide.

An Introduction To Direction Finding Methodologies

All direction finding methodologies are meant to determine the physical or geographical location of a source of radio frequency energy. The choice of an appropriate direction finding methodology to use for a given application is largely a function of the target signal's characteristics, such as frequency and modulation, but is also influenced by the propagation environment as well as cost and complexity.  Recent advances in the development of hybrid direction finding methodologies attempt to overcome some of these restrictions and increase accuracy by using a combination of methodologies.

The Rebirth Of HF

HF, or “high frequency” technology, usually refers to signals with frequencies in the 3 MHz to 30 MHz range, all though, many practical cases extend these frequencies as low as 1.5 MHz. One of the best-known applications of HF is worldwide or global communications. Government, military, and commercial broadcasters can reach listeners worldwide using HF frequencies. This paper explores the unique properties of HF that enable global communications.

From The 1920s To The 2020s – Bandwidth Has Always Been King

Over time, the telephone replaced the telegraph, and now cellular and voice over Internet protocol (VoIP) technology are replacing the landline. As more communication is done wirelessly and over the Internet, we are becoming more interested in increased bandwidth. This is because bandwidth places a limit on how quickly we can send information through a channel such as an optical fiber or a section of the radio spectrum.
