Support for unlicensed and shared spectrum, and low cost, multi-operator small cells, will allow LTE and 5G to encroach on WiFi’s territory in enterprise wireless and urban hotzones. But WiFi is moving in the other direction, taking on many characteristics of cellular technologies with enhanced quality of service, security and other features. As the lines between licensed and unlicensed spectrum blur, WiFi will evolve alongside cellular and be part of the broader 5G platform, say its supporters – and a good example is its rising support for hyperdensity, a key goal of the cellular community. This will be supported by the next iteration of the IEEE 802.11 standards on which WiFi is based (802.11ax is particularly targeted at delivering gigabit…
