In RF engineering, when discussing antennas, SISO and MIMO now apply to the number of antenna "inputs" and antenna "outputs" that a communication channel between two or more devices may have. In this case, the SISO RF system will have only a single antenna from one device and a single antenna from another device. Unlike control engineering, the number of "inputs" and "outputs" does not refer to the inputs and outputs of the communication system, but rather to the antennas in the spatial multiplex scheme. Using the MIMO RF antenna, the number of antennas sent from one device and the number of antennas received from another device determine the order of the MIMO channels (TX antenna x RX antenna） Using the SISO antenna system, signals sent from a device will interact with the environment and will be absorbed or reflected according to these environmental variables. Eventually, the signal energy from the SISO antenna system can reach the receiving antenna from one or more spatial paths. In this case, the path with the highest signal energy is ideal because it is usually the least attenuated or distorted. Signals from other paths can actually be interfering because they can degrade or delay due to interaction with the environment.   For MIMO systems, these multi-space paths from one device to another are used to enhance communication between two devices, either by increasing the number of active streams used or by increasing the reliability of communication channels. Both methods can improve throughput by increasing channels or improving channel quality, reducing errors, and using channel capacity more efficiently.

Distributed antenna systems (DAS) for indoor coverage of mobile communication voice and data traffic have to cover an ever wider range of requested services. For this, Luxun Antenna offers the matching antenna portfolio.Our antenna families cover the frequency range from 380 MHz to 6 GHz. Thanks to these extremely broadband radiation properties, cost-intensive and space-wasting installation of separate antennas for individual applications is unnecessary, facilitating the integration of distributed antenna systems in existing buildings with reasonable material and installation expense and simultaneously enabling an aesthetic design. Excellent PIM behaviour makes these antennas deeply interesting for DAS in a multi-operator environment.

PMRExpo 2023 from November 28th to 30th in Cologne, where Europe’s leading security communications exhibition will once again take center stage.    This event will showcase renowned exhibitors from around the globe, displaying their cutting-edge products, solutions, and innovative achievements in the field of secure communications and professional mobile radio. From telecommunications to application solutions, control centers and security technology, infrastructure components, equipment accessories, and service providers, exhibitors of various industries will present their expertise in the field.   PMRExpo is internationally recognized as a top-tier event that brings together users from security services, critical infrastructures, logistics, industry, professional trade, and other sectors. Here, authorities and organizations gather to stay at the forefront of new trends, exchange technical know-how, and establish valuable domestic and international connections.

The choice between omni-directional and directional antennas is case-specific. If you just want to cover all directions and connect with multiple service providers in your area, an omni-directional antenna is the best for you. But if your priority is a strong signal in only one direction, you can go for a directional antenna. Although here you will have to identify the location of the nearest cellular base station to place the antenna in the same direction. Directional antennas are also recommended for rural regions as the distance between cellular stations is more when compared to urban areas.

Omni-directional antenna, that is, in the horizontal direction of the map shows 360 ° are uniform radiation, that is, usually called non-directional, in the vertical direction of the map shows that there is a certain width of the beam, in general, the smaller the width of the wave flap, the greater the gain. Omni-directional antenna in the mobile communication system is generally used in suburban area system station type, large coverage area.

As an important part of the network, the base station antenna is the entrance and exit of the wireless communication base station system, and only through the antenna can the transmission of signals be realized and the mobility of the terminal can be supported. In the 5G era, under the new requirements of frequency, power consumption, coverage, etc., active antennas and MassiveMIMO antennas required by 5G base stations have gradually become the main players in the base station market. Looking at the centralized procurement of antennas in 2022, China Mobile purchased a total of 20.6752 million indoor distribution system equipment centralized procurement projects in 2022-2023, accounting for 94% of the total statistical procurement volume, and the strong demand for deep coverage and application drove the unprecedented growth of room branch antenna demand. In the face of new opportunities for the development of 5G digital intelligence society, the antenna market is expanding while the differentiation is also intensifying. The regionalization of markets and the specialization of products also bring more development opportunities to some suppliers in specific regions or with special products

An antenna is a metallic structure that captures and/or transmits radio electromagnetic waves. Antennas come in all shapes and sizes from little ones that can be found on your roof to watch TV to really big ones that capture signals from satellites millions of miles away. The antennas that Space Communications and Navigation (SCaN) uses are a special bowl shaped antenna that focuses signals at a single point called a parabolic antenna. The bowl shape is what allows the antennas to both capture and transmit electromagnetic waves. These antennas move horizontally (measured in hour angle/declination) and vertically (measured in azimuth/elevation) in order to capture and transmit the signal. SCaN has over 65 antennas that help capture and transmit data to and from satellites in space.  

The parabolic antenna, often referred to as the “big pot” antenna due to its shape, is a widely used technology in telecommunications and satellite communications. In this blog post, we will explore the various applications of parabolic antennas. Satellite Communication: Parabolic antennas serve a crucial role in satellite communication systems. They are used to transmit and receive signals between ground stations and satellites. These antennas provide high gain and directional properties, enabling long-distance and reliable communication for applications such as broadcasting, internet connectivity, and remote sensing. Wireless Networking: In wireless networking, parabolic antennas are used to establish long-range links between devices. They are commonly employed in point-to-point connections to achieve high data transmission rates over extended distances. This makes them ideal for connecting remote locations, such as rural areas or isolated buildings, to the internet or local networks. Radio Astronomy: Parabolic antennas play a significant role in radio astronomy. These antennas are used to receive weak radio signals from celestial objects, helping scientists explore and study the universe. By capturing and focusing radio waves, parabolic antennas enhance the sensitivity and resolution of astronomical observations. The parabolic antenna, with its distinctive shape resembling a big pot, has proven to be a valuable technology in various fields. From satellite communication to wireless networking and radio astronomy, its reliable long-range capabilities have been instrumental in enabling global connectivity and scientific exploration.

What is MIMO Omni antenna? Omni-directional antenna products specifically designed for use with multi-port MIMO / MANET radio systems. These products feature multiple discrete antennas within the radome, each with its own RF connector.698-4000MHz Mimo OMNI Antenna is popular in 5G market. Does MIMO antenna really work? MIMO antennas will help condition the outdoor signal and get you better data rates. But if the signal outside your building isn't usable to begin with, MIMO antennas might not help. You can certainly still give the MIMO antenna a shot, but you may still be unable to connect. What are the disadvantages of MIMO? The main disadvantage of MIMO system is that the multiple antennas required extra high cost RF modules. The extra RF modules increase the cost of wireless communication systems. In this research, the antenna selection techniques are proposed to minimize the cost of MIMO systems.
