Telefonica has launched a 4G flat-rate tariff plan for its LTE pilot network subscribers in Madrid and Barcelona. The service is currently exclusively available to large corporate customers and public institutions. Customers will initially access the service via USB modems, at speeds of up to 100 Mbps for download and 50 Mbps for upload. Telefonica's 'Internet 45' 4G services package will be available for a monthly fee of EUR 45. Telefonica will continue the deployment of its LTE network in Spain's regional capitals in 2012.
