French cellcos Orange France and SFR (originally Societe Francaise du Radiotelephone) have been accused of failing to meet the demands of mobile data subscribers in La Defense, the major financial district for the city of Paris. A report in Le Parisien claims that only Bouygues Telecom, which has fewer 3G data customers than its larger rivals, has escaped the current capacity issues facing the cellcos. Orange France’s head of mobile networks, Sebastien Plantier, is quoted as saying that La Defense is one of France’s five busiest locations for mobile internet services and that ‘everything is not perfect’ there. Orange has deployed around a dozen 3G-enabled base stations in the district but admits that actual data rates are five times slower than those being touted for its mobile internet service. With SFR experiencing similar problems due to high demand, the situation has been exacerbated by the so-called ‘canyon effect’ resulting from the number of tall buildings and the multitude of networks, signals and communications scrambling 3G. For its part, Orange France has pledged to install more equipment in the area in the coming weeks to alleviate the problem.
