The 6OGHz radio bridge as a part of local area netwo.rk with I OOMbps rate is described in application to the remote control of research experiment in real time.Millimeter wave radio links are nowadays intensively investigated for application in local office or home computer networks [ 11. It offers new opportunities in the performance of complex technological, testing and measuring equipment.In this work 60GHz radio channel was incorporated to the cable local area network on the ETHERNET technology "point-to-point" for the remote control of the research equipment. PCI network adapters allow to work with two speeds: 10 Mbps and 1OOMbps.Adjustment and testing of connection were carried out as well as for the millimeter wave radio bridge at the frequency 34GHz in the cable network 10BASE-T [2]. With this in mind that the radio channel and the cable connection are operating simultaneously, the test file is transmitting continuously and the linear signal is observing with the oscilloscope.The software of remote control system consists of two parts and is placed on two computers connected with local network. The program on the operator's computer is guiding and fulfils functions of the client. It automatically determines the network address of the removed computer, which in this system is a server, generates and transfers necessary files, accepts and analyzes results of the operation of measuring equipment connected to a server, sends managing influences. At the final stage of experiment the system comes back to the initial condition, working files leave the server.The tranceiver consists of two separated modules with transmitting and receiving antennas and operates at the intermediate fi-equences 2,4GHz and 1,5GHz (Fig.l,2). In the construction of tranceiver planar waveguide-microstrip antenna with 27dB gain is used, the up-converter trasferes the IF to canying fiequency 60GHz with input power 4dBm and output power of two-band signal 1,7dBm, the down-converter to the IF gives conversion losses 7dB. The choice of the IF 2,4GHz will allow in the future to use the equipment of standard IEEE 802.1 1 wireless access. MMW generators for the converters (local oscillators) employ Gum diodes. Converters are performed in a rectangular 3,6 )( 1,8mm2 waveguide section. lOMbps or 100 Mbps linear signal in the transmitter is transferred to the IF with the microstrip p-i-n diode modulator. In the receiver the linear signal after detector of the IF is gained up to a standard level and acts to the network adapter of the computer. The duplex mode operation is achieved without diversity of carrying frequencies :for two directions of communication. Taking into account time division of the signals for two directions of transfer under protocol Ethernet 10Base-T and 1OOBase-TX and the fact that IF signal is eliminated with p-i-n diode modulator during transfer pause it is sufficient to change polarization of antennas and to separate them in space.
