New wireless routers target industrial sector
6 May 2015Siemens has expanded its Scalance M wireless router series with the addition of two new devices.
Siemens has broadened its Scalance M portfolio with the launch of its M876-3 and M876-4 systems.
The first of these, the Scalance M876-3, is claimed to be ideally suited for transmitting data via third generation wireless internet access (3G).
Elsewhere, the Scalance M876-4 enables to can connect to subnets and automation devices via LTE (Long Term Evolution) wireless standard, which is widely used throughout Europe.
The system's high bandwidths, performance capabilities and transmission speeds mean the routers are able to be deployed in a diverse range of applications.
These range from industrial remote access solutions, such as teleservice to the integration of distant substations in energy distribution or water treatment systems, as well as high-bandwidth applications, such as video surveillance.
"In addition to the integrated 4-port switch, which can be used to connect up to four end devices, the new mobile wireless routers each come with two antenna connections, making it possible for operators to use multiple antennas (antenna diversity) and thus increase both signal quality and bandwidth," the company added.
The manufacturer's new devices are characterized by their compact housing in the design of its Simatic S7-1500, which means that they save space in the control cabinet.
In addition, the routers arrive with one digital input and output, for setting up secured VPN connections with key-operated switches while the devices are equipped with their own redundant power supply for bridging short-term power failures.
The Scalance M876-3 supports HSPA+ and EVDO, which, dependant on infrastructure, enables high transmission rates to end devices of up to 14.4 Mbit/s and back to the telecommunications network of up to 5.76 Mbit/s.
The other new device, the Scalance M876-4 offers downlink speeds of up to 100 Mbit/s and uplink speeds of up to 50 Mbit/s via LTE.
