The requirements concerning environmental influences (temperatures, dust, humidity) are high and can only be fulfilled by adding protection in the case of mostly sensitive network components. The networks should also be compact and light. At the same time, they should be as easy to operate as possible. This is demanding. However, if you get the chance to observe the systems live in operations and receive positive feedback but also criticism from the network administrators in charge, this is an indescribable experience. We benefit from these experiences as do the soldiers on operations because we directly implement these experiences in the project.
