Ericsson’s David Hammarwall predicts that 5G will surpass the LTE global network in a few years. He said that 4G will “reach its limits as a technology as connectivity demands change,” paving the way for 5G. Additionally, he said that there are built-in inefficiencies in 4G technology, such as always broadcasting signals, which limits energy saving and reduces performance. He said while 5G is a way off, the flaws in 4G can help predict the improvements that 5G may have. He told Computer Business Review he thinks 5G will have better energy efficiency, a lean design in signal transmission, a reduction in power consumption, a solution to a current spectrum crunch, a new range of frequencies, an unlicensed spectrum and faster connectivity, which will improve the consumer experience.
Hammarwall said that the 5G will set a new standard and built out of two key elements: the evolution of LTE and a new radio access, he told CBR. He predicts that by 2021 more than 70 percent of Internet content will be video-driven.
CBR reports “5G will also be reliant on small cell technology, including femtocells and picocells, which have so far not seen huge adoption.” While small cells have “been a key scene for some time,” they haven’t quite taken off. With 5G coming, they will be key for indoor and outdoor solutions. Ericsson is in the process of building partnership to build small cell sites worldwide for consumers and businesses.
“We are seeing small cells deployments focused on both consumers and business users,” Hammarwall told CBR. “Generally speaking, outdoors and in public venues, small cells will support both, but, for business users in office buildings, there can be more business-critical applications, which may require a higher density of small cells.”
Existing infrastructure is important. Dave Fraser, CEO of Devicescape said, “WiFi already provides the superior connectivity experience inside millions of buildings and will remain fundamental to the Smartphone user. In public spaces, free amenity WiFi of the kind offered by numerous consumer-facing businesses and premises owners has become a rich, dense connectivity resource.”
