EN-DC technology enables mobile operators to boost 5G speeds and coverage by leveraging a 4G network. It also leveraged carrier aggregation which combines multiple channels of the spectrum to gain greater efficiencies and boost data speeds over a wireless network. In a demonstration carried out in Samsung’s lab in Korea, the company successfully combined 40MHz of 4G frequency and 800MHz of 5G frequency in mmWave, achieving 5.23Gbps in data speeds to a single device. In 2018, Samsung demonstrated its 5G capabilities with one of the first multi-gigabit 5G New Radio (NR) data connections with speeds of more than 1.7Gbps. In 2019, Samsung surpassed its record by reaching data speeds of 2.65Gbps, which was followed by 4.3Gbps speeds in a 2020 demo. Samsung broke the record with data speeds of 5.23Gbps, using EN-DC technology. Subscribers whose current modem cannot support the upgraded speeds may also upgrade to a WiFi 6 modem for free, but with a required 24-month relock period.
