Czech fixed and mobile telecoms operator Telefonica O2 CR says more than 110,000 people have signed up to its 3G CDMA service. The popularity of the service has been driven by its O2 Internet Mobil service which uses CDMA technology and is capable of providing data speeds of up to 3.1Mbps. Telefonica O2 CR plans to cover 30% of the Czech population with the CDMA network.
