1,000 Times More Mobile Bandwidth Inevitably Requires Core Network Virtualization
A business as complicated as telecommunications necessarily leads to “silos” of knowledge, since nobody can understand “everything.” That is applicable to mobile Internet access as well.
In other words, what we think is required for supplying more bandwidth to end users on 4G and 5G networks requires understanding how core networks must change.
By 2018, 62 percent of Long Term Evolution networks will support the Network Functions Virtualization (NFV) specifications. Virtualized networks, in other words, are becoming an integral part of mobile access functions.
To vastly increase available bandwidth, many tools are needed, ranging from new spectrum and small cells to Wi-Fi offload, better antenna technology, better radios, spectrum sharing and virtualized networks.
