Wide bandwidth, supporting all frequency bands of operators. Support multi-channel MIMO to enhance network capacity. Small in size, lightweight, and easy to install. Elevator antennas have the characteristics of high gain and narrow beam, and are targeted for covering elevator shafts. Venue shaped antennas have excellent beam convergence and sidelobe suppression capabilities, with rapid signal attenuation outside the coverage range, clear boundaries, effective avoidance of cross zone interference, and are more conducive to multi cell segmentation in dense scenes, achieving capacity improvement. The tunnel wall mounted antenna is a four port antenna that can support the construction of 4TR in the 2.6G or 3.5G frequency bands. It adopts a streamlined design to reduce wind resistance and is used to improve reliability in tunnels, enabling the rapid deployment of 5G distribution systems inside the tunnel.
