Hirschmann's technological strength is primarily reflected in automotive communication systems, multimedia electronics, automated network solutions, and electronic control systems. To clarify the company structure, a multimedia division, Hirschmann Multimedia Electronics GmbH, was established in early January 2003. Hirschmann has now acquired its former sister company, PAT GmbH, located in Ettlingen, whose electronic control systems division is now part of the Hirschmann Group.

As a manufacturer of integrated antenna systems, Hirschmann has developed many innovative products, such as a receiving antenna integrated into the rear bumper of a car, and is also a pioneer in modular antenna systems used in automotive rear windows. Hirschmann has successfully launched a series of mobile transmitting and receiving systems suitable for broadcast reception, communications, navigation, vehicle (ship) fleet management, and communications.

Hirschmann also holds a leading position in the field of multimedia communications, including systems and components for transmitting analog and digital broadcast signals for professional CATV networks and home satellite ground station systems.

As experts in automation networks, Hirschmann established a fiber optic Ethernet network at the University of Stuttgart in Germany in 1984, and in 1990, it launched HIPER-Ring redundant Ethernet. Hirschmann provides a complete and comprehensive data communication system suitable for industrial and office environments, with a product range ranging from Gigabit Ethernet, Fast Ethernet, and Ethernet products to fieldbus systems and ASI connectors for actuators and sensors. These products are widely used in office communications, production automation, process control, traffic control, and independent machine control systems.

A HIRSCHMANN switch is a device that performs information exchange in a communication system.

In computer network systems, the concept of switching represents an improvement to the shared working mode. A hub is a shared device. The hub itself cannot identify the destination address. When host A on the same local area network (LAN) transmits data to host B, the data packet is broadcast on a network with a hub architecture. Each terminal determines whether to receive the packet by verifying the address information in the packet header. In this mode, only one set of data frames can be transmitted on the network at a time; if a collision occurs, it must be retried. This method is called shared network bandwidth.

Key Features of HIRSCHMANN Switches (Germany)

The main functions of HIRSCHMANN switches include physical addressing, network topology, error checking, frame sequencing, and flow control. Currently, switches also have new features such as support for VLANs (Virtual Local Area Networks), link aggregation, and some even have firewall functionality.

Learning: Ethernet switches know the MAC address of each device connected to each port and map the address to the corresponding port, storing it in the MAC address table in the switch's cache.

Forwarding/Filtering: When a data frame's destination address is mapped in the MAC address table, it is forwarded to the port connecting to the destination node, not all ports (unless the frame is a broadcast/multicast frame, in which case it is forwarded to all ports).

Loop Elimination: When a switch includes a redundant loop, the Ethernet switch avoids loop creation through the Spanning Tree Protocol (STP), while allowing for backup paths.

In addition to connecting networks of the same type, German HIRSCHMANN switches can also interconnect different types of networks (such as Ethernet and Fast Ethernet). Many modern switches offer high-speed ports supporting Fast Ethernet or FDDI, used to connect other switches in the network or provide additional bandwidth for bandwidth-intensive critical servers.
