The indoor unit is a VCR-sized unit that houses the communications electronics that includes interface with the customer’s equipment such as computers or telephones. The IFL consists of coaxial cables that connects the outdoor unit to the indoor unit. The third component of a VSAT network is the satellite itself.
What is VSAT How many units are there?
A very-small-aperture terminal (VSAT) is a two-way satellite ground station with a dish antenna that is smaller than 3.8 meters. The majority of VSAT antennas range from 75 cm to 1.2 m. Bit rates, in most cases, range from 4 kbit/s up to 16 Mbit/s.
What is IDU in VSAT?
IDU stands for Indoor Unit and ODU stands for Outdoor Unit. Refer VSAT basics before understanding IDU and ODU as these are terms associated with VSAT (Very Small Aperture Terminal). VSAT system is used to provide remote connectivity with satellite to avail voice and data services.
What are the components of VSAT?
A VSAT consists of two parts: a transceiver placed outdoors in direct line of sight to the satellite, and a device that is placed indoors to interface the transceiver with the end user’s communications device, such as a PC. The transceiver receives or sends a signal to a satellite transponder in the sky.
What is the difference between ODU and IDU?
The term ODU is used in Split-Mount Microwave systems where an Indoor Unit (IDU) is typically mounted in an indoor location (or weatherproof shelter) connected via a coaxial cable to the ODU which is mounted on a rooftop or tower top location.
What is feed in VSAT?
This is the equipment that enables the terminal to transmit and receive signals to and from the satellite. The ODU includes: the reflector. the feed, which both transmits signals toward and receives signals back from the reflector.
Is VSAT a microwave?
Editorial Team – everything RF. Very Small Aperture Terminal (VSAT) is a ground station with dish antennas that transmits and receives data from satellites.
What is outdoor unit in networking?
Description: The Outdoor Unit (ODU) is part of the digital microwave transmission system. It supports a point-to-point digital fixed radio service and works together with the Indoor Unit (IDU) to provide multiple types of service interfaces.
What is the purpose of IDU?
An IDU is used solely for the purpose of receiving and converting satellite transmissions into usable data for television service and Internet access.
What is ODU in modem?
posted this at Dec 20, 2019. The ODU is the outdoor unit of the microwave system. The ODU is mainly used to convert the frequency or amplify the power of the signals. Functions and Features. The ODU is used for the frequency conversion and amplification of signals.
What is uplink and downlink?
In satellite telecommunication, a downlink is the link from a satellite down to one or more ground stations or receivers, and an uplink is the link from a ground station up to a satellite. Some companies sell uplink and downlink services to television stations, corporations, and to other telecommunication carriers.
What is VSAT and hub station?
A VSAT network consists of a central hub (master earth station), many remote VSATs, and the satellite transponder space segment. The hub station is always larger than the remote VSATs and is frequently located near the user’s main data processing center.
What is Hub in satellite communication?
A satellite gateway (also referred to as a teleport or hub) is a ground station that transmits data to/from the satellite to the local area network. It houses the antennas and equipment that convert the Radio Frequency (RF) signal to an Internet Protocol (IP) signal for terrestrial connectivity.
What is an ODU?
Odu definition
An entity for processing in an Optical Transport Network (OTN). An ODU comprises a frame or series of frames in their native protocol, encapsulated in a digital wrapper for network management purposes. See also digital wrapper, encapsulate, frame, network management, OTN, and protocol.
What is an ODU in HVAC?
Split Air Conditioner – Outdoor Unit (ODU), Usage: Industrial Use, Residential Use.
What is the full form of ODU?
ODU – Output Display Unit.
What is RF feed?
In a radio antenna, the feed line (feedline), or feeder, is the cable or other transmission line that connects the antenna with the radio transmitter or receiver. In a transmitting antenna, it feeds the radio frequency (RF) current from the transmitter to the antenna, where it is radiated as radio waves.
What is feed point impedance?
The feed impedance of the antenna results from a number of factors including the size and shape of the RF antenna, the frequency of operation and its environment. The impedance seen is normally complex, i.e. consisting of resistive elements as well as reactive ones.
Why feed is used in antenna?
The antenna feed includes the functions of transforming the radio waves into electrical signals and transmitting them to the receiver components. In general, it is considered to be part of the antenna that is being used for the conversion purposes of the radio waves into the electric signals and vice versa.
What is difference between satellite and microwave?
This is because apart from the limited frequency bands used by satellite communications, terrestrial and satellite microwave communications are actually using the same technology, and the only difference is the distance between sender and receiver.
What is a microwave satellite?
Satellite Microwave
It is used for broadcasting and receiving signals. The signals are transmitted to space where these satellites are positioned and it retransmits the signal to the appropriate location. It acts as a repeater as it only receives the signal and retransmits it.
