CBRS is a US scheme that dynamically allocates 3.5GHz spectrum on demand to anyone, such as a building owner, for their exclusive use. A similar scheme is being developed by ETSI for use in Europe in the 2.3 and 2.4GHz band. Both have huge potential for standalone or neutral host small cell networks, and incorporate strategies to avoid incumbent users being disadvantaged.
There are several competing standards for ubiquitous wireless connection of the Internet of Things, including two specific to LTE alone. Operators are actively deploying both on a nationwide basis. We summarise what these are, review their commercial status and consider the implications.
While the press hype up and distract you about the long term potential of 5G, there is a quiet revolution in progress. Almost everywhere, you will find most mobile operators around the world are quietly reallocating their spectrum, upgrading from 2G to 3G and 4G. Some have switched off 2G entirely. This has implications for smartphones, small cells and infrastructure choices in the coming years ahead.
One of the areas of confusion and even misinformation relates to control of calls when entering and leaving a building. In the early days of 3G femtocells, hand-in wasn’t supported and hand-out was more by luck than judgment. The situation has evolved considerably by enhancement of the 3G standards and inherent features within the 4G standard. A combination of improved RF planning and SON automation provides a complementary toolkit to address the problem.
Today the MulteFire Alliance released its first formal specification Release 1.0. We spoke with Mazen Chmaytelli, President of the MulteFire Alliance, to understand the current scope, progress to date and the next steps towards commercial deployment.
