Cellnex UK and Three UK, two mobile data companies, have teamed up to provide business-minded commuters with end to end connectivity. The popular Brighton Mainline route, favoured by hard-working commuters, will soon have the sort of business communications the workaholics heading for the City have been craving for years. The partnership will see Three host its mobile voice and data equipment on new Cellnex UK infrastructure along the entire London to Brighton railway route.
