5G Antenna - C-Band with 3.5 GHz
5G is expected to be available to end customers by 2020. Now the first worldwide basic frequency for 5G mobile radio networks is also emerging. In all probability, 5G will start in the C-band, on which the network supplier Huawei, among others, will plead in a position paper. In Berlin, Deutsche Telekom is currently already testing the 5G standard 5G New Radio, or 5G NR for short, which uses the C band with frequencies around 3.7 GHz.
Omnidirectional high-performance antenna for 5G C-band base stations and terminals
With a frequency range from 3.4 GHz to 3.8 GHz, the BOA34006NF is already prepared for 5G applications in the C band. A high antenna gain of 6 dBi ensures good reception. The antenna is equipped with an N-type female connector.
The omnidirectional BOA base station antenna consists of a linear array encapsulated in a robust fiberglass shell with a thick-walled mounting base. The antenna is IP67 protected and can withstand extreme temperatures from -40 °C to +85 °C. The antenna can be used in a wide range of applications. This enables reliable and long-term outdoor use. New applications such as Vehicle 2 Infrastructure (V2X) or Vehicle 2 Everything are possible thanks to the antenna in the 3.5 GHz band.
What does 5G in the C-band mean for the user?
So far, the 3.5 GHz frequency range has not been used for mobile communications, so investment in new hardware is inevitable. Router as well as existing antennas are not able to work with these frequencies.
CBRS stands for Citizens Broadband Radio Service and offers private companies the opportunity to use local frequency ranges in the 3.5 GHz band. Companies and industry can thus set up their own mobile radio networks in production or in office buildings. Also in Europe, some parts of the 3.5 GHz band are not allocated to providers such as Telekom and Vodafone, but are distributed locally to private companies.
The BOA34006NF offers the optimal prerequisites to enable private companies to communicate via the 3.5 GHz bands 42.43, 48 and 5G.
Coverage and Capacity Layer
The higher the frequency, the lower the propagation of the waves and thus also the range. As a result, more base stations are needed for the same coverage. To counter this, the networks are divided into different layers, as is currently the case with 4G. The C-band around 3.5 GHz should serve as a "Coverage and Capacity Layer" and thus represent a compromise between capacity and network coverage.
Super Data Layer
In later expansion stages a "Super Data Layer" will be added, which is designed for particularly high data rates. The frequency is not yet fixed, but will probably be in the 28 GHz range and therefore have a very small range.
In ländlichen Regionen ist der Betrieb von vielen Basisstationen für relativ wenige Anwender nicht wirtschaftlich. In diesen Regionen wird der „Coverage Layer“ genutzt, mit dem sich eine möglichst große Netzabdeckung erzielen lässt. Wahrscheinlich wird hier der Bereich um 700 MHz vorgesehen, der aktuell schon von 4G LTE genutzt wird. So können die Netzbetreiber 5G in ihre bestehenden 4G Netze integrieren und einen Teil der Infrastruktur weiter nutzen.
