Field support engineers and technicians provide on-site support for network connections and for detecting flaws related to hardware, networking, software, configuration, and inconsistent power supply. The engineers and technicians must support the installation tasks, including testing, documentation, and setup. Field support specialists also take part in meetings and come up with suggestions to improve the supporting services. The complexity of networks and sourcing of relevant talent makes it difficult for service providers to keep their clients happy. To accommodate all the planned and emergency maintenance, service providers must use freelance field support services when needed.
