Realizing that meeting the needs of festivals and large events with thousands of people concentrated in an area at peak times is a big challenge for network operators.
With the sudden increase in traffic in these areas, surrounding base stations must be able to meet temporary service requirements. In addition, network operators also use COW mobile broadcasting vehicle solutions with high configurations to serve subscribers throughout the event to avoid service congestion.
However, preparing solutions for these problems is not without difficulties while the number of devices from many vendors on the vehicle and adding high configurations, requiring multiple devices to be installed on the antenna.
On a COW mobile broadcasting vehicle, many different vendors with different 3G/4G and 5G technologies are always integrated depending on each coverage location.

With the current solution by sharing a common antenna, devices such as Hybrid Coupler, Diplexer and Combiner will be installed on the cable ladder or hung in empty positions. In case of needing to change the configuration or vendor, the installation will take a long time, not to mention the assembly process will cause VSWR and Cell crossover errors. In addition, when the number of Cells increases, the number of devices needed will also increase while the space in the cabinet will gradually become narrower.
Tamagawa would like to propose an integrated solution in the form of modules with all Vendors together. When the need is deployed, users do not need to spend much time connecting.
The device is designed with a size of 1-2U mounted on a 19-inch rack
