What is RF planning tool?
What is RF planning tool?
In the context of mobile radio communication systems, RF planning is the process of assigning frequencies, transmitter locations and parameters of a wireless communications system to provide sufficient coverage and capacity for the services required.
What is frequency planning?
Frequency planning is actually an implementation of capacity. planning. Frequency planning together with capacity planning tries to. maximise the information flow (voice or data) over the radio interface and. simultaneously to maximise the efficiency of the radio network.
What is frequency planning in GSM?
GSM mobile system like other communication systems has the frequency band used in the systems depends on the type of the GSM system, cellular system means dividing the area region the system installed in it in to many cells, each cell and each channel must has it’s own frequency, so the frequency planning is very …
What is RF capacity?
The RF Capacity is an item added by Hatchery. It comes in 3 tiers and can be inserted into the Methane Digester Generator, the Shredder or the Fertilizer Mixer to increase the size of their internal Redstone Flux buffers.
What is BCCH and TCH in GSM?
Abstract: The GSM system has two type of frequency carriers, namely the frequencies that carry the broadcast control channels (BCCH) and the frequencies carrying only traffic channel (TCH). The focus is on the downlink performance, i.e. it is assumed that the downlink is the limiting link in the system.
Why do we reuse frequency?
Frequency reuse improve the spectral efficiency and signal Quality (QoS). In Frequency Reuse scheme, total bandwidth is divided into different sub-bands that are used by cells. Frequency reuse scheme allow WiMax system operators to reuse the same frequencies at different cell sites.
What is frequency hopping used for?
Frequency hopping is a technique mainly used to keep two or more RFID readers from interfering with each other while reading RFID tags in the same area.
What is uplink and downlink frequency in GSM?
GSM-900 uses 890 – 915 MHz to send information from the Mobile Station to the Base Transceiver Station (BTS) (This is the “uplink”) and 935 – 960 MHz for the other direction (downlink), providing 124 RF channels spaced at 200 kHz. Duplex spacing is 95 MHz.
What is the range of RF frequency?
around 300 GHz
Radio frequency (RF) is the oscillation rate of an alternating electric current or voltage or of a magnetic, electric or electromagnetic field or mechanical system in the frequency range from around 20 kHz to around 300 GHz.
What is RF theory?
“RF” refers to the use of electromagnetic radiation for transferring information between two circuits that have no direct electrical connection. Time-varying voltages and currents generate electromagnetic energy that propagates in the form of waves.
What is RF and why do we use it?
“RF” refers to the use of electromagnetic radiation for transferring information between two circuits that have no direct electrical connection.
What are radio frequency devices?
Radio frequency or RF devices are the devices which work on Radio frequencies. They are wireless devices. Examples of RF devices include your mobile phone, router, Bluetooth devices, FM radios, walkie talkies, radars, etc.
What is a radio channel frequency?
Definition of radio frequency. : any of the electromagnetic wave frequencies that lie in the range extending from below 3 kilohertz to about 300 gigahertz and that include the frequencies used for communications signals (as for radio and television broadcasting and cell-phone and satellite transmissions) or radar signals.
What is the frequency of radio stations?
All FM radio stations transmit in a band of frequencies between 88 megahertz and 108 megahertz. This band of the radio spectrum is used for no other purpose but FM radio broadcasts.
