Ofcom announced today that it has appointed Hyacinth ‘H’ Nwana (pictured) to lead the Spectrum Policy Group and Steve Unger as its new chief technology cfficer (CTO).

Ofcom’s Spectrum Policy Group oversees the management of the allocation of the UK’s airwaves - the valuable resource behind all wireless communications for mobile phone networks, broadcasting, businesses, consumers and essential services.

Mr Nwana, known as ‘H’, joins from Arqiva, where he has been managing director of Mobile Media Solutions since 2005.

At Arqiva, he was responsible for all the company's activities in mobile broadcast TV, wireless broadband (WiMAX/WiFi), datacasting and new wide (WANs), metro (MANs) and/or national network roll out opportunities.

Previously he was executive director at Quadriga Worldwide.

‘H’ will join Ofcom on September 28 and report to Ed Richards, chief executive.

Mr Richards said: “I am delighted we have been able to recruit someone of ‘H’s calibre.  His experience as a technical expert and as a successful business executive will provide an important contribution to the development of our spectrum work in the years ahead.”

Mr Unger, the new CTO, has been director in the Competition Group, where he has led many projects, most notably the current pay TV market investigation.

He joined Ofcom in 2003 as director of telecoms technology, having been head of network analysis at Oftel.

The CTO is the most senior technical policy colleague leading Ofcom’s specialists who advise on current and future technologies.

He will take up the post immediately - reporting jointly to Peter Phillips, partner for strategy and market developments, as well as to Stuart Mcintosh, Competition Group partner.
