(Telecompaper) Weko, the Swiss Competition Commission, said it has opened an investigation into Swisscom for possible abuse of its dominant market position in broadband connections. Swisscom demands high prices to deploy connections for companies in tender offers, Weko said. Its competitors, which include other telecommunications companies, rely on the network infrastructure of Swisscom for such projects. According to Weko's preliminary investigation, Swisscom charges competitors high prices so that they refrain from submitting a competitive offer.
