Dynamic spectrum access (DSA) and mesh wireless networks are expected to have “a significant impact on the use of new spectrum” within the next decade, according to a report from communications regulator Ofcom.
Ofcom’s Technology Research and Development report, published last week, also said the regulator did not expect the same result in this timescale for cognitive radio and software defined radio (SDR).
“It is typical in many areas of technology, including wireless, for only a few developing technologies to succeed,” said the report.
DSA, which allows devices to roam onto any available wireless network, would make more efficient use of the frequency spectrum.
It is expected to be ready to deploy in five to ten years’ time.
Mesh networks are expected to provide complementary coverage to existing mobile wireless systems, for example, by extending hotspots and providing broadband networks to rural communities.
R&D into cognitive radio and SDR continues, but the report said “in some cases niche applications exist where the technologies are applied, however universal adoption or the case for it does not seem likely in the near future”.
The emerging technologies, investigated as part of Ofcom’s research programme, are predicted to generate up to £6.5bn in revenues for the UK economy over the next 20 years.
