Train antenna requirements: 5G X-Plecs 4x4 MIMO cross-polarized / dual-polarized
DB Fahrzeuginstandhaltung was looking for a cross-polarized 5G MIMO train antenna for its Colibri IT solution portfolio to promote digitization in rail and road traffic.
The antenna had to meet the following criterieas:
- In order to optimize the possible throughput, dual-polarized roof antennas that can use signals with different polarizations should explicitly be offered
- The heights of 50 and 80 mm and the width of 120 mm should not be exceeded
- The antennas should be suitable for the curved roofs of double-deck coaches
- A robust, maintenance-free and MIMO-capable multiband antenna with high gain in a very compact design for:
- 5G
- LTE
- GSM
- WLAN
- GNSS
In order to optimize the possible throughput, dual-polarized roof antennas that can use signals with different polarization should expressly be offered.
Our solution:
With the OmPlecs®-TOP 200 AMR product family (height 60 and 40 mm), Antonics has had suitable cross-polarized multiband antennas in its portfolio for some time.
For the tender, however, the new, particularly narrow roof antenna X-Plecs®-TOP AMR (height 50 and 80 mm, width 120 mm) was offered in variants from 2x2 to 8x8 MIMO, which is also suitable for the curved roofs of double-decker coaches.
Antonics offered the OmPlecs®-TOP 200 AMR MF-05 with Wi-Fi 6E (3x3 to 6x6 MIMO) as an indoor antenna.
Antonics thus fulfilled all the "must" criteria formulated in the tender and also numerous "should" criteria.
Here is the perspective of the Deutsche Bahn
Antonics' antennas fulfilled the required specifications in critical aspects and proved their superiority in the competition
