The UK Spectrum Policy Forum's recommendations for the future use of Licence Exempt Radio Spectrum illustrate the importance of license-exempt spectrum for future business models, use cases and applications.
Among the more-important observations are that use of license exempt spectrum will be central for Internet access and machine-to-machine apps.
Most of the recommendations are among those you would expect. International spectrum harmonization is particularly important, and might be most difficult at frequencies below 1 GHz.
THe 870 –876 MHz and 915 –921 MHz bands are likely to be critical for supporting future M2M demand growth in Europe, for example.
interference mitigation is key, as are "politeness protocols" for Wi-Fi access, especially for Long Term Evolution devices using the 5 GHz Wi-Fi spectrum.
To nobody’s surprise, the group recommends the United Kingdom seek to maximize spectrum availability for wireless access systems. particularly expansion of the 5 GHz band.
More stringent receiver performance requirements and a phase out of legacy technologies that do not incorporate suitable interference mitigation mechanisms also are recommended.
In the longer term, automated registration of Internet-connected devices could be considered.
Legacy "impolite" technologies raise interference issues, particularly for 2.4 GHz video links, and device receiver performance also is an issue.
Facebook will keynote Spectrum Futures in Singapore, Sept. 10, 2015, featuring Chris Weasler, Facebook and Internet.org global head of spectrum policy & connectivity planning.Facebook and Internet.org.
Other confirmed speakers will discuss spectrum sharing between LTE operators, spectrum sharing between Wi-Fi and LTE, new access platforms and the critical role spectrum plays for coming 5G networks.
At the same time, the intimate relationship between applications (Internet of Things), core networks (SDN. NFV, cloud computing, fog computing) and all access networks will be examined.
In the coming next generation network, clearly separating spectrum and mobile networks from Wi-Fi and fixed network access, core networks and cloud infrastructure, will be nearly impossible.
