Samsung Electronics has successfully held the world’s first 5G mobile communication technology demonstration in Korea, ushering in a new era of content and communication possibilities.
- 5G mobile communication technology is the true successor to 4G Long Term Evolution (LTE) network technology
- It is several hundred times faster than the current 4G LTE services, which operate at approximately 75 Mbps per second.
- Once commercialized, 5G will remove obstacles that prevent large-volume contents from being transmitted to smart devices, opening up the possibility of ultra high-definition (UHD), 3D and holographic video content delivery.
- 5G technology will go beyond satisfying consumer demand for ultra-fast data transmission, unlocking new potential for hardware and services, such as ultra-high definition connected cameras, ubiquitous access to Cloud services and the use of wearable connected devices.
- LTE Advanced, an upgrade of the existing 4G LTE technology is due for commercial deployment in Korea in 2013 and will provide services at 150 Mbps, twice as fast as 4G LTE. In contrast, 5G is expected to be several hundred times faster than LTE Advanced as it operates at a much wider bandwidth, akin to letting traffic flow from a single lane to a full expressway
- 5G requires the use of higher radio frequencies compared to existing 4G LTE services. 4G LTE networks typically operate around the 2 GHz frequency range. The developed 5G technology operates at 28 GHz, known as the millimeter-wave Ka band where the wavelengths are much shorter. *Please see Figure 1 below.
- Such high frequency waves were thought unsuitable for use in mobile networks due to their lack of range. To overcome this limitation, Samsung has developed a new adaptive array transceiver technology that utilizes 64 antenna elements in handsets and base stations to ensure performance. In contrast, current mobile technology uses only one or two antenna elements in handsets and two or four at the base station
- Commercial deployment of 5G technology is expected around 2020.
