During the winter, MastIT — together with 3 Sweden — has been responsible for the construction, design, and installation of the new indoor network at Avicii Arena. The project has involved extensive work, including building new power and infrastructure systems, installing a new fiber network, and setting up connection equipment and racks for all Swedish mobile operators.

“The Avicii Arena project is one of the largest indoor network projects in Sweden in 2025, and it has been a demanding installation where design, technical solutions, and integrations from all Swedish operators have required exceptional coordination and quality in every detail — all within a tight timeline ahead of the arena’s reopening,”
says Jimmy Karlsson, Founder of MastIT Group.
