Steffen Malkowsky together with his 5G research colleagues from Lund University, Sweden, and the University of Bristol, UK, have set a new world record for spectrum efficiency – overwhelming today’s existing 4G technology 22-fold, tech website, Futurism, reports.
In spite of the success of the research, Malkowsky stated that “the goal is for 5G to increase the total transmission capacity by a factor of 1,000. This is still a big step; just imagine how fast that would be!!!
The 5G technology achieves rates of 145.6 (bits/s)/Hz for 22 users, each modulated with 256-QAM, on a shared 20 MHz radio channel at 3.51 GHz with an 128-antenna massive MIMO array.
This presents an important step towards a new type of wireless communication.
These results, however, are experimental and not real world. The users were stationary while in reality, people and their phones are often in motion.
Also, being in a highly-controlled environment with no interference from other cellular signals, the tech’s performance may decline when applied in a real word setting.
Researchers have long been conducting experiments using a form of 5G technology called Massive MIMO (Multiple-Input Multiple-Output) in response to the insufficiency of the 4G technology.
With this technology nearing completion and ready for deployment, Nigerians will be left to wonder how long it will take before the technology reaches the country, given the long period 4G took.
Even at that, 4G only recently became available to a very microscopic few of Nigeria’s over 100 million internet users.
