Ericsson BFL901 009/4 RBS 6601 base station Base Station Module

The Ericsson BFL901 009/4 is a baseband unit for the RBS 6601 base station. The baseband is where the digital work of the cell happens: it handles the signal processing for each carrier and sector and passes the result to the remote radios over fibre, so it sets how much capacity a site can carry rather than how far it reaches. In the RBS 6601 the baseband sits indoors with the main unit while the radios stay at the antennas, which is what allows the mast to carry almost nothing but the radio itself. Confirm the carrier and sector configuration your site runs before ordering, since baseband units differ in capacity. Tech-Star (UK-based, shipped worldwide) supplies Ericsson base station components for ongoing maintenance projects.
