FireWire
FireWire, or IEEE 1394, is a high-performance serial bus originally developed by Apple computer in the early 1990s. The baseline standard handles throughput rates of up to 400 Mbits/s. The IEEE 1394 Trade Association is revising the specification to increase this transfer rate to 3.2 Gbits/s. While devices must be within 4.5m of the bus socket to conform to the specification, up to 16 devices can be daisy-chained together for a maximum run of 72 m. IEEE 1394 however, is less than ideal for T&M applications. For example, the 1394 cables are not industrial graded, the isochronous mode allows this bus to guarantee bandwidth but does not guarantee that no data will be lost, andapplication testing shows 1394 data transfers to be much lower than their theoretical values.
You can control and communicate with 1394-based instruments through the drivers that ship with the device as a DLL interface to your software development environment including LabVIEW and LabWindows/CVI.

Wireless
Wireless Ethernet (IEEE 802.11) is another emerging standard for I/O buses that can be leveraged in instrument control applications. While it is capable of slower transfer rates than standard Ethernet and suffers from some of the same security issues, it offers the convenience of remote control without the necessity for cabling. Another potential wireless bus alternative that is not discussed here is Bluetooth.
