Microwave links (MWL) in operational telecommunication networks provide new opportunities to improve rainfall monitoring, especially in cities and low-income countries. We used signal strength data from 364 MWLs sampled every 10s to estimate rainfall in Gothenburg. We compared these estimates with ...

Most long-range telecommunication systems employ microwave links requiring high power transmitters, both terrestrial and satellite-based. These satellites are typically equipped with 50–100 traveling wave tubes (TWTs) based on slow thermionic electron sources that cannot be switched at high speeds, and...
Most long-range telecommunication systems are based upon microwave links. The transmitters use microwaveamplifiers which in the very near future will be re... WI Milne,KBK Teo,E Minoux,... - 《Journal of Vacuum Science & Technology B》 被引量: 140发表: 2006年 Broadband microwave amplifiers ...
However, unlicensed links can be interfered with by other users, which can cause reduced throughput or complete link outage. Such interference is generally heavier in high density population areas and cities, where 100’s or 1000’s of radios may be competing for the same spectrum in a given ...

in Europe, there are many existing microwave links in several countries. It will take time to move these links to other bands such as E-band. The 15–23GHz spectrum will remain as the global high-volume microwave bands. E-band will become a global high-volume band, both on its own and...
Microwave is a form of high frequency radio signal (operating at thousands of MHz) in which the signal is not broadcast but is transmitted in a straight line through the air. Due to the curvature of the earth and the fact thatmicrowave signalscannot bend, microwave links are only useful for...
