Millimeter waves have a wide range of applications in fields such as communications, radar, remote sensing, and astronomy. While the 5G construction is in full swing, with the freezing of the R16 version, people gradually focus on the key technologies of the next stage of 5G. Among them, millimeter wave technology is known as the killer of 5G.
The biggest feature of millimeter wave is the rich frequency band resources. Compared with the difficulty in the allocation of resources in the Sub-6 frequency band, millimeter wave can easily allocate bandwidth resources above 100MHz, even up to 400MHz or 800MHz. Based on such abundant frequency bandwidth resources, the wireless transmission speed of millimeter wave 5G can easily exceed Sub-6 by several times.
The millimeter wave has high frequency and short wavelength, so the size of the antenna is smaller. Under the same volume, more antennas can be integrated, a narrower beam can be formed, and a very high spatial resolution can be obtained.
The 5G millimeter wave system launched by Luowave SDR is composed of a mature USRP N321 (N310) module plus a millimeter wave module. The millimeter wave module integrates the array antenna, and a complete set of 5G millimeter wave experimental system can be quickly built with only a computer. With this system, 5G teaching, research and demonstration can be carried out conveniently.
The millimeter wave module can be individually controlled by a computer, with a built-in configurable high-performance frequency source, and a wide beam scanning range of ±60︒ provides sufficient guarantee for the beamforming research.
