Nokia Siemens Networks (NSN) has been selected by two Polish operators to enhance their mobile broadband capacity.
The company has agreed a deal with Aero2 and its partner operator Polkomtel, the firm behind the Plus network, to help expand their GSM, HSPA+ and Long Term Evolution (LTE) networks.
As well as improved coverage, the plan aims to deliver advanced voice and data services for Poland's mobile broadband users.
Polkomtel board member Tobias Solorz said he is "convinced" that the firm's long-term partnership with NSN "will allow us to meet any challenges".
Dietmar Heinrichs, head of the Polkomtel customer business team at NSN, added: "The growing popularity of smartphones is putting huge pressure on operators' networks. At the same time, customers' service expectations are increasing."
The agreement signed by the companies covers delivery, integration and maintenance of the operators' mobile access networks, while a separate deal has also been signed covering care services.
On completion of the upgrade, HSPA+ will be positioned in the 900 MHz frequency band, with LTE initially offered in the 1,800 MHz frequency band.
