MIMO ceiling GSM/UMTS/LTE antenna
Indoor ceiling antenna designed for receiving and transmitting GSM/UMTS/LTE signal. The antenna operates in bands 700/800/900/1800/1900/2100/2600 MHz. It is often used as part of GSM/UMTS/LTE signal repeaters. Two RG316 cables (with double shielding) a length of 3 m are attached to the antenna, which are terminated with two SMA (m) connectors.
MIMO technology is a method of increasing the capacity of a radio link by using multiple transmitting and receiving antennas, which mainly use multipath propagation, thus achieving higher throughput and lower transmission error rate.
Connector specifications SMA:
These are high-frequency connectors with screw connection mechanism. The characteristic impedance of the connector is 50 Ohm and the operating frequency range up to 18 GHz. There are two types of SMA connectors, namely SMA and RP-SMA. Most of the current cellular routers are equipped with SMA connectors for connecting Wi-Fi / 2G / 3G / LTE / GPS antennas terminated by proticates. It is also used as a standard connector in RF measuring technology. They are characterized by high reliability, durability, high mechanical stability and optimal electrical properties.
Cable specifications RG316:
RG316 coaxial low-loss high-frequency cable that is compatible with connectors applicable to a cable with the outer diameter of 2.49 mm. The frequency range is 0 - 3 GHz. The RG316 cable is often used in radio frequency and telecommunication applications, for the transmission of high frequency signals, and also in wireless devices. It is suitable for applications that require good performance and stability in high temperature environments. The operating temperature of this cable is -55 to + 200 ° C. The shortening factor is set to 0.7. There are also specially modified RG316 for outdoor use, which are UV resistant, as well as for use in extreme conditions. It is made of different materials and different qualities.
