| While mobile edge computing options were much hyped in the beginning, they are starting to proliferate as suppliers -- both startups and existing -- offer new products and as-a-service offerings. The primary driver for edge computing is the growth of IoT applications with large data sets and low latency requirements. These IoT applications need compute processing and storage near where the information is gathered -- i.e., edge computing -- instead of transporting this information to faraway centralized data centers.Spectrum limitations have slowed the rollout of 5G services in many countries, including the U.S. and much of Europe. Dynamic spectrum sharing (DSS) is a new technology that enables mobile operators to offer 4G and 5G services over the same band of spectrum. This enables operators to quickly respond to bandwidth demands by allocating spectrum on various services -- i.e., 4G vs. 5G -- on their network. DSS requires software upgrades to both the radio access network (RAN) and 5G.The migration to 5G requires operators to deploy large numbers of new base stations for geographic coverage and to deliver high-speed bandwidth with low latency. Three large suppliers -- Ericsson, Huawei and Nokia Networks -- have traditionally dominated the large RAN market, combining for more than $35 billion per year, according to Doyle Research. Proponents of Open RAN hope to break this supplier monopoly by enabling new suppliers and, ultimately, radically reducing prices. Open RAN is designed to run on lower-cost commodity hardware.Citizens Band Radio Service, or CBRS, is another emerging wireless networking trend. CBRS is a repurposed band of unlicensed spectrum recently cleared for commercial use in the U.S. Enterprises can deploy CBRS in select geographic areas -- e.g., mining, large warehouses or manufacturing -- to enable their own private 4G, and soon 5G, networks. This enables enterprises to control the quality of service (QoS) and ensure the security of the devices and applications. Most organizations will deploy CBRS as the WAN connection to local LAN routers, such as Wi-Fi and Bluetooth, which will connect the individual IoT devices.Wi-Fi remains the dominant method of connecting PC, tablets, phones and other devices in the enterprise. Wi-Fi 6, or 802.11ax, is the latest upgraded version of the venerable Wi-Fi standard, which offers improved performance and enables QoS for critical applications. It increases the number of devices that can simultaneously connect to a single Wi-Fi access point and adds features to improve the battery life of IoT devices, such as Wake on wireless LAN. Wi-Fi 6 is designed to better serve densely populated zones, such as stadiums, hotels and convention centers. -- ???????? | |||
