Vodafone Czech Republic lodged a complaint with the country’s anti-monopoly office about an LTE network-sharing deal struck between rivals O2 and T-Mobile last month.

According to a report by Mobilnet.cz, cited by Telecompaper, Vodafone made the complaint on the grounds that the deal breaches regulations set out by the Czech Telecommunications Office (CTU) that network-sharing deals should not be exclusive.

The Czech Republic’s O2, majority-owned by the PPF investment group since January, signed an LTE network-sharing agreement with Deutsche Telekcom’s T-Mobile to cover the whole country, except for Brno and Prague. The deal involves the sharing of radio access equipment.

Both operators stressed they would keep their core networks independent and maintain separate business strategies. The fight on speed and quality of service, they said, would continue.

By contrast, Vodafone believes the deal will hinder competition.

According to the report, Balesh Sharma, the general director of Vodafone Czech Republic, said documents submitted to the anti-monopoly office should be enough to spark an investigation.

If no enquiry begins, Vodafone reportedly plans to submit a complaint to the European Commission.
