Ericsson has delivered 2 million radio base stations so far, It took Ericsson some 20 years to install one million radio base stations as announced in 2007, but it took only three years to deliver the next million according to company statement. 

The two millionth radio base station was an Ericsson RBS 6000 unit, delivered as part of a mobile broadband network expansion project. 

"Ericsson's milestone delivery is proof of the explosive growth of mobile broadband. The exponential growth in consumer adoption, data speeds and technology advancements continues to transform the way people communicate. As the world leader in mobile communications, Ericsson is proud of its role in advancing the industry," said Ericsson's Vice President and Head of Radio Networks Ulf Ewaldsson.

A main driver behind the massive acceleration of deliveries is Ericsson's RBS 6000, a multi-standard, energy-efficient base station that supports GSM/EDGE, WCDMA/HSPA and LTE in a single package. 

Ericsson claims to supply the majority of HSPA networks operating at speeds of 14.4 Mbps or higher. In addition, Ericsson says that it is the only supplier participating in all major 4G/LTE network builds currently underway.
