Our WLAN, GSM and LTE antennas are characterized by their 1a industrial standard. They are ideally suited for use in machines and plants
ELCO provides you with the right digitization concept. We are there for you - from the needs analysis to the procurement of your new hardware
Our WLAN, GSM and LTE antennas are assembled ex works with standardized connectors. This enables fast assembly on site.
Whether indoor WLAN antenna or outdoor LTE antenna: ELCO offers you systems with cellular and/or WiFi connectivity. We have what you are looking for. Guaranteed.
In addition to radio systems, we can also equip you with the appropriate WLAN, GSM and LTE antennas - also as a complete package. We will be pleased to advise you.
Do you want to get down to business and optimize your entire value chain? We offer you a variety of complete solutions.
With LTE, data rates of up to 300 Mbit/s can be achieved - that's the theory. In practice, however, we hardly ever receive the maximum performance. Not even when the transmission towers are conveniently located. The biggest problem is the losses that occur on the way from the transmission mast to the router in your production halls. If the router is also poorly positioned, the LTE signal either arrives weakened or, in the worst case, not at all. With mobile use, there are even more hurdles, since the position of the receiver is constantly changing. An LTE antenna can provide relief and ensures that you always receive the best possible LTE signal, both stationary and mobile.
The electromagnetic field is deposited in a certain direction based on the radiation characteristic of the antenna and increases the radiation power here. In theory, a perfect omnidirectional antenna has a 360° homogeneous radiation characteristic. A directional antenna, on the other hand, produces a directed radiation in a defined direction. Physically, the more acute the angle, the higher the radiated power.
ELCO supplies you with high-performance LTE antennas. In addition to the indoor version, you can of course also get LTE outdoor antennas from us. With their help, you can achieve a good connection even in rural, less well-developed regions and increase reception by up to 40 percent. But it's also worth using an LTE antenna in big cities - ideally, you can get the most out of your Internet speed.
An antenna is used as a transmitting and receiving device for electromagnetic waves. These waves transmit our useful signal of the application. The antenna can basically be used for transmitting and receiving the useful signals. The antenna is physically a two-pole, also called a dipole.
Currently, the LTE signal in Germany is mainly transmitted over four frequency ranges: 700MHz, 800 MHz, 1,800 MHz and 2,600 MHz. We offer LTE antennas for these frequency ranges. In addition, you will find so-called multi-band LTE antennas that cover the 900 MHz and 1,500 MHz bands in addition to the common frequency ranges. They can be used as a universal LTE antenna, so to speak. Of course, the LTE antennas we offer fit all common LTE routers.
GSM antennas are mainly used for the so-called GSM standard (GPRS/EDGE), i.e. the mobile phone frequency range at 900 MHz. This usually concerns mobile telephony and mobile Internet - provided that no more stable connections (e.g. LTE or UMTS) are available. Since GSM signals are strongly attenuated by barriers such as walls and coated windows due to the high frequencies, reception in buildings is often very poor. A GSM antenna remedies this situation and provides you with a faster and more reliable mobile connection.
2G is not suitable for large data volumes; however, mobile telephony and sending SMS still run via GMS. This also applies to many industrial applications, such as monitoring machines and control systems. Although the GSM standard is being phased out, the frequency range at 900 MHz will remain and will continue to be used for mobile voice calls. So, despite of the switch to 3G and 4G, reception will still have to be ensured in the future by means of a GSM antenna.
Similar to an LTE transmission tower, the WLAN signal also "radiates" from a central point. Depending on where this point is located and what obstacles the signal has to overcome on its way to the receiver, the signal strength can vary enormously. This is especially true if many end devices (desktop PCs, printers, smartphones, tablet PCs, etc.) access the WLAN network and communicate via it. In this case, one resorts to one or more WLAN antennas that amplify the signal and/or supply other areas of the building with wireless Internet.
WLAN antennas differ in terms of their WiFi frequency: On the one hand, there are models that operate in the 2.4 GHz range and, on the other, versions for the 5 GHz frequency. So-called dual-band antennas that cover both frequency ranges are now also available.
In high-frequency technology, the dipole forms an open oscillating circuit with a defined natural resonance frequency with the help of the given inductance and capacity of the lines. When current flows through it, an electric field forms at the ends and a magnetic field around the coil of the antenna. Thus, the magnetic field is horizontal and the electric field is vertical to the antenna. Together, this results in an electromagnetic field.
The antenna gain defines the directivity and the associated efficiency in relation to the reference antenna. In practice, an isotropic radiator, i.e. an omnidirectional radiator, is always specified as the reference. The isotropic radiator transmits in all spatial directions with an equally strong electromagnetic field. By cutting in, i.e. aligning in a defined area, the characteristic is strengthened and leads here to an antenna gain.
The polarisation of an antenna indicates the course of the electromagnetic field in relation to the earth's surface. There are two main types of polarisation: linear and circular. Linear polarisation is further subdivided into vertical and horizontal polarisation. With vertical polarisation, the electric field is perpendicular to the earth's surface, and with horizontal polarisation, it is vertical. With circular polarisation, the field strength vector rotates in a direction away from the antenna. In this case, it rotates counterclockwise or clockwise in the direction of propagation. In all cases, it is important that the transmitting and receiving antennas are tuned to each other so that reception losses can be avoided.
VSWR stands for Voltage Standing Wave Radio and is a measurement that describes how well the antenna matches the respective transmission frequency. The smaller the VSWR value, the better the antenna is matched to the transmission line and the more power is delivered to the antenna. The minimum VSWR is 1.0, in which case no power is reflected from the antenna. The ratio is formed from the difference of the maximum to the minimum outgoing and return voltage.
