Samsung Electronics announced what it claims are two industryfirst milestones in the development of fifth-generation (5G) telecommunications networking technology, as the company clocked 7.5 Gb/s, the fastest-ever 5G data transmission rate while in a stationary environment. The company was also the industry's first to achieve an uninterrupted and stable connection at 1.2 Gb/s in a mobile environment from a vehicle traveling at over 100 km/h. In addition, Samsung's recent stationary test was also the industry's first successful 5G test that was conducted in an outdoor setting. Previous successful 5G tests throughout the industry have been conducted in stabilized indoor environments, including laboratories. Meanwhile, the mobile test took 5G testing to another level, as it was conducted from a vehicle racing at high speeds on a 4.35-km professional outdoor race track. Both the stationary and mobile tests were conducted over a 28-GHz 5G network. Until now, the industry as a whole has not used higher frequencies, such as 28 GHz, despite their speed-related benefits, due to the likes of short communication range. However, the company claims to overcome these obstacles through its own hybrid adaptive array technology, which uses millimeter-wave frequency bands to enable the use of higher frequencies over greater distances. The recent milestones were also a sevenfold increase upon testing results from May 2013, when the company became the industry's first to achieve 1 Gb/s over a 28-GHz 5G network.
