You may not have heard of Huawei, but its products may well be in your house. Last year the company, based in Shenzen, China, overtook Ericsson to become the world’s largest manufacturer of telecoms equipment. It controls a quarter of the EU market in telecoms infrastructure and has won more than half of the contracts for 4G technology awarded in Europe, including big deals with EE (formerly Orange and T-Mobile), O2 and 3UK.
