UK Broadband has unveiled a 4G internet service named Relish, which it claims will quickly deliver fibre speeds without a landline connection. Launched at an event in London on Wednesday, Relish is available in Central London from today, after the firm first announced plans to rollout the service back in February 2012. UK Broadband is the service in four offerings – home broadband, business broadband, mobile broadband and dedicated business internet for firms that use a lot of data, which will be more expensive that the basic business offering but will also offer faster speeds.
