Spread spectrum makes it possible to have as low a frequency reuse factor as 1, if each base station is divided into 3 cells by means of 3 directional sector antennas. This corresponds to a system spectrum efficiency of over 1 × 100 × 0.0017 = 0.17 (bit/s)/Hz per site, and 0.17/3 = 0.06 (bit/s)/Hz per cell or sector.
A pendulum with a period of 2.8 s and a frequency of 0.36 Hz. For cyclical phenomena such as oscillations, waves, or for examples of simple harmonic motion, the term frequency is defined as the number of cycles or repetitions per unit of time.
The Earth's naturally varying electric and magnetic fields are measured over a wide range of magnetotelluric frequencies from 10,000 Hz to 0.0001 Hz (10,000 s). These fields are due to electric currents flowing in the Earth and the magnetic fields that induce these currents.
The electricity sector in Honduras has been shaped by the dominance of a vertically integrated utility; an incomplete attempt in the early 1990s to reform the sector; the increasing share of thermal generation over the past two decades; the poor financial health of the state utility Empresa Nacional de Energía Eléctrica (ENEE); the high technical and commercial losses in transmission and ...
A few projects are underway to increase the electricity transfer between the 50 Hz (eastern Japan) and 60 Hz networks (western Japan) which will improve power reliability in Japan. [11] In April 2019, Hitachi ABB HVDC Technologies secured an HVDC order for the Higashi Shimizu project to increase the interconnection capacity between the 60Hz ...
802.11ay is a type of WLAN in the IEEE 802.11 family of Wi-Fi WLANs.It is an improvement on IEEE 802.11ad rather than a new standard. [3] [4] It uses the 60 GHz band [5] and has a transmission rate of 20–40 Gbit/s and an extended transmission distance of 300–500 meters.
The following is a list of albums, EPs, and mixtapes released in 2012.These albums are (1) original, i.e. excluding reissues, remasters, and compilations of previously released recordings, and (2) notable, defined as having received significant coverage from reliable sources independent of the subject.
