Communication specialist NetModule is ushering in the 5G era with new routers:
The first device – the 5G high-end router NB3800 5G – is based on the proven NB3800 product series and is specifically certified for railroad applications according to EN 50155 and EN 45545. Like all NetModule routers, the NB3800 5G offers a modular hardware design and feature-rich software that makes it a universal communications gateway. The basic equipment includes WLAN access with IEEE 802.11ac (WiFi 5) standard, GNSS for positioning as well as 2 Gigabit and 3 Fast Ethernet ports. Thanks to standard interfaces, the device can be configured to customer specifications and equipped with the required modems depending on availability. The currently used 5G modem supports time division duplex (TDD) as well as frequency division duplex (FDD) and offers up to 4x4 MIMO. In 5G NR mode, the frequency bands N1 (2100), n3 (1800), n7 (2600), n8 (900), n78 (3500) are supported; in 4G LTE mode, B1 (2100), B3 (1800), B7 (2600), B5 (850), B8 (900), B20 (800), B42 (3500). This is important because the router will fall back to LTE and sometimes even UMTS due to a lack of 5G coverage.
The router NB3800 5G supports both 5G standalone (SA) and 5G non-standalone (NSA). This is especially necessary in the current build-up phase, since not all mobile networks have been upgraded to 5G SA yet. In LTE advanced mode, 4G Cat20 with channel bundling is offered. Theoretically, the routers achieve data rates of 5.5 Gbps in download mode and 1.6 Gbps in upload.
Applications include fleet management, operational data transmission, condition monitoring, passenger infotainment, e-ticketing, video surveillance in HD quality and telematics.
The NB3800 5G is available immediately.
In addition, NetModule now also offers 5G-capable antennas that are backward compatible with the previous mobile radio standards. In the case of the rail antennas, the antenna design also remains the same flat and light, and the external mechanics have been retained. This means that existing systems can be retrofitted or converted without any problems. Because MIMO (Multiple In / Multiple Out) technology plays an important role in the 5G standard, 4 receive antennas (RX antennas) are required for the 5G core bands. For transmitting operation, the currently available modems for the frequencies of the European network operators require three antennas. The NetModule 5G routers support these requirements.
NetModule is planning the NB2800 5G Vehicle Router for applications in buses, streetcars and automotive before the end of the year. It will be followed by the 5G Industrial Router NB1800 5G, targeting the industrial automation and remote monitoring markets. With NetModule 5G-enabled routers, enterprises across industries can gear up for the new connectivity:
- Public transport – passenger WLAN on bus or train, additional use of channels for operators' own operational purposes, including safety-critical applications such as video surveillance, ticketing and operational data collection.
- Automotive/Transportation: autonomous & teleoperated driving – Faster, more reliable and improved real-time sensor data transmission for buses or driverless logistics vehicles. Data security is ensured by the safeguards included in 5G so that no unauthorized person can access the vehicle.
- Industrial automation – 5G's higher bandwidth, improved speed and reliability enable factory automation to be more effective. In addition, 5G's secure data transmission also scores here.
