About us

CellMax is a Swedish company and since 2014 part of the Rosenberger group. The company develops and markets high performance base station antennas for mobile networks (2G/3G/4G/LTE). Using a unique technology, CellMax’s products brings a dramatic positive impact to the overall data performance of the mobile network.

CellMax’s revolutionary antenna technology virtually eliminates power losses within the antenna, resulting in significantly higher radiated RF power in the cell. Increased signal strength and reduced interference significantly improves data throughput and data capacity, allowing the operator to become truly spectrum efficient. The overall benefit for the network operator is a dramatically lower production cost per MB delivered.

CellMax’s customers include several of the world’s largest mobile operators and manufacturers of telecom equipment, such as Ericsson, Nokia, Huawei, T-Mobile, Telia Sonera, Globe Telecom, Hutchison, Aircel, Telecom Italia, Telecom Austria and AT&T.
