Samsung has accelerated its "5G" radio tests with a 7.5Gbit/s transmission to a stationary test device while pushing its "5G Rainbow" of performance and technology metrics that might help define the future wireless technology.
The South Korean giant says the 7.5Gbit/s test was the first ever undertaken outdoors on its 28GHz test network. A driving test at speeds of over 62mph on the millimeter wave testbed achieved a stable connection at 1.2 Gbit/s, Samsung said.
Here's a video from Samsung on the tests:
This pre-5G testing builds on work that Samsung was doing on 28GHz millimeter radio in 2013. Samsung said then it was getting speeds at 1 Gbit/s using a "64 element" adaptive array antenna to improve the notorious signal propagation characteristics of the high-frequency bands. (See 60GHz: A Frequency to Watch.)

Samsung is also pushing its "5G Rainbow" parameters to help the 5G "user experience." Here's what the company says about that:
Most recently, Samsung proposed the 5G Rainbow to other industry members. The 5G Rainbow identified seven core technical pillars of 5G technology that would truly ensure a differentiated 5G user experience. These pillars are maximum data rate, spectral efficiency, speed of mobility, data transmission rate at the cell boundary, the number of simultaneous connections, communication delays, and cost. In order to address these technical needs, Samsung has already been developing a diverse range of key technologies, such as transmission technologies for high-frequency bands, multiple access schemes and low latency networks.
Never forget, of course, that what "5G" actually is yet to be defined by the industry. (See The 5G Landgrab and DoCoMo's 2020 Vision for 5G.)
