Relish's dream to connect London homes with wireless broadband, rather than traditional landlines, could be in trouble. UK Broadband, the company behind the service, has reported losses of £37.5 million for 2014 -- almost four times what it was the year before. To make matters worse, turnover slipped from roughly £2 million to £1.5 million over the same period. Relish was launched in June 2014 as a simpler, but capable broadband alternative to the likes of BT, Sky and Virgin Media. Instead of copper and fibre cables, the company relies on 4G connections to deliver the internet to its customers. The advantages are plentiful -- you don't need to pay for a landline, and because Relish's network is already up and running, you don't need an engineer to install anything. Once you've signed up, a router is sent round within the next working day and you can instantly get online. The concept is similar to the mobile broadband packages offered by EE, Three and other UK carriers, although here there are no restrictive data allowances. So what's gone wrong?
