Si.mobil is set to come first in the race to offer LTE services on a commercial basis in Slovenia after sealing a deal with Nokia Siemens Networks (NSN).
NSN said it will be the power behind the Telekom Austria-owned operator's 4G services, which will mean Si.mobil's customers in Bled, Ljubljana and Brnik gain access to super-fast mobile broadband.
Subscribers in these regions could secure up to 100 Mbps data speeds, which Si.mobil's Johannes Nabecker said represent "a significantly superior" customer experience with fast download and response times.
Si.mobil has around 640,000 subscribers and a market share of 29.7 percent.
NSN said it will use its flexi multi-radio base station devices to give Si.mobil use of its single radio access network.
On top of that, Si.mobil will also use NSN's technology for managing networks - NetAct - to consolidate monitoring of its 2G, 3G and 4G networks.
Daria Horvat, NSN account manager, said it took only a month to implement the agreement.
He added: "We are proud to partner Si.mobil in its endeavour to provide the best user experience to customers."
The vendor is currently rolling out a series of updates to its Liquid Net portfolio as it aims to consolidate its position in the mobile broadband space.
