Organisation Description

Our history of delivering telecoms training dates back to 1958 when we occupied Wray Castle on the shores of Lake Windermere. Initially specialising in radio and maritime communications, we began training the telecommunications industry during the 1990s, establishing ourselves as the leading training organisation in this field.

60 years on we still uphold this reputation, now providing training on telecommunication technologies across the industry sectors and on a global scale, including mobile and fixed network operators, transport, defence, energy and emergency services amongst others.
