5th-Generation Wireless Systems (abbreviated 5G) is the marketing term for technologies that satisfy ITU IMT-2020 requirements[1][2] and 3GPP Release 15.[3] Key features of 5G include high throughput, low latency, high mobility and high connection density[4]. 5G will use additional spectrum in the existing LTE frequency range (600 MHz to 6 GHz[5][6]) and Millimeter wave bands (24-86 GHz), which can support data rates of up to 20 gigabits per second (Gbit/s)[7]. 5G infrastructure will use Massive MIMO (Multiple Input Multiple Output) to significantly increase network capacity.[8][9]
ITU has divided 5G network services into three categories: enhanced Mobile Broadband (eMBB) or handsets, Ultra-Reliable Low-Latency Communications (URLLC), which includes industrial applications and autonomous vehicles, and Massive Machine Type Communications (MMTC) or sensors[10]. Initial 5G deployments will focus on eMBB[11] and fixed wireless[12], which makes use of many of the same capabilities as eMBB.
