Vodafone claims to have put another 150 5G antennas into operation at more than 50 locations in Frankfurt am Main. This means that 5G should now be widely available in Frankfurt: “From the Main Tower to the palm garden. From Goethe University to the Old Opera ”, as Vodafone describes it in a rather flowery way.
1.8 GHz for the first time: For the first time, Vodafone’s new antennas also include those with 1.8 gigahertz frequencies. The 1.8 GHz range, also known as the “5G midband”, lies between the 700 megahertz range (“5G lowband”, intended for the coverage of the flat country) and the 3.5 GHz frequency range (“5G Highband ”, intended for the big city) and thus complements these two areas. Accordingly, the midband represents a compromise between highband and lowband in the technical data. That means: 1.8 GHz offers a greater range than the 3.5 GHz but a shorter range than 700 MHz. For the surfing speed, 1.8 GHz means: significantly slower than 3.5 GHz, but noticeably faster than 700 MHz. The following graphic shows the differences:
Vodafone defines the purpose of the three areas as follows:
Car2X: Data transmission in real time (latency) should be possible in the future with all three frequency ranges. This is important, for example, for networked road traffic, in which cars, bicycles and trucks used mobile phones to face each other – even in rural regions. However, the 5G mobile network competes with pWLAN in the Car2X communication application area, as is used, for example, by Volkswagen in the current Golf: New Golf warns other cars of dangers.
The 3.5 gigahertz frequencies bring very high bandwidths of more than one gigabit per second to a comparatively small area. In this way, a mobile radio station supplies 5G with a radius of up to one kilometer. According to Vodafone, the 3.5 gigahertz frequencies are suitable for connecting thousands of people, robots and machines simultaneously with 5G. This is why this frequency range is primarily used for expansion in industrial halls and in high-traffic locations, as Vodafone writes. For example, in the Volkswagen Arena at VfL Wolfsburg and in the Munich Allianz Arena.
The 700 megahertz frequencies reach further into the country and better bring fast networks into the houses. In this way, a station supplies a radius of up to ten kilometers with a fast network. According to Vodafone, bandwidths of around 200 megabits per second are realistic. That could also close white spots and bring fast networks to places where surfing was often only at a snail’s pace. Dynamic Spectrum Sharing is also used in this area, which improves rural LTE coverage. Deutsche Telekom also uses Dynamic Spectrum Sharing for this purpose: Telekom – 40 million users now provided with 5G.
The following illustration shows how to imagine Dynamic Spectrum Sharing. The cellular antenna detects whether it is only used by 5G users or only by LTE users or by both user groups. And automatically adjusts your resources:
The 1.8 gigahertz frequencies in turn, 5G should bring more to cities. Dynamic Spectrum Sharing is also used here, so that 5G and LTE users benefit from more networks at the same time with the same expansion step.
Around 1,000 5G antennas are currently transmitting at more than 350 locations in the Vodafone network, the company said. (PC world)
