In CIDSS, there is a requirement for the commanders who are on the move to access the resources at formation HQ's, which is a distributed LAN. In order to meet this requirement, an interface unit called Wireless Message Transfer Unit (WMTU) has been designed which will transfer Ethernet packets over wireless media. This unit is deployed in a LAN environment. It provides seamless integration with Ethernet network. It supports 2 channels of Digital radio. The Unit is also provided with two serial ports.
WMTU is a Pentium based Single board computer with PC 104 bus interface and the add on cards designed using industrial grade components provides interface with wireless media. The system is ruggedised to meet the stipulated environmental and EMI / EMC requirements.
Bharat Electronics Limited (BEL) was set up at Bangalore, India, by the Government of India under the Ministry of Defence in 1954 to meet the specialised electronic needs of the Indian defence services. Over the years, it has grown into a multi-product, multi-technology, multi-unit company serving the needs of customers in diverse fields in India and abroad . BEL is among an elite group of public sector undertakings which have been conferred the Navratna status by the Government of India.
The growth and diversification of BEL over the years mirrors the advances in the electronics technology, with which BEL has kept pace. Starting with the manufacture of a few communication equipment in 1956, BEL went on to produce Receiving Valves in 1961, Germanium Semiconductors in 1962 and Radio Transmitters for AIR in 1964.
In 1966, BEL set up a Radar manufacturing facility for the Army and in-house R&D, which has been nurtured over the years. Manufacture of Transmitting Tubes, Silicon Devices and Integrated Circuits started in 1967. The PCB manufacturing facility was established in 1968.
In 1970, manufacture of Black & White TV Picture Tube, X-ray Tube and Microwave Tubes started. The following year, facilities for manufacture of Integrated Circuits and Hybrid Micro Circuits were set up. 1972 saw BEL manufacturing TV Transmitters for Doordarshan. The following year, manufacture of Frigate Radars for the Navy began.
Under the government's policy of decentralization and due to strategic reasons, BEL ventured to set up new Units at various places. The second Unit of BEL was set up at Ghaziabad in 1974 to manufacture Radars and Tropo communication equipment for the Indian Air Force. The third Unit was established at Pune in 1979 to manufacture Image Converter and Image Intensifier Tubes.
In 1980, BEL's first overseas office was set up at New York for procurement of components and materials.
In 1981, a manufacturing facility for Magnesium Manganese Dioxide batteries was set up at the Pune Unit. The Space Electronic Division was set up at Bangalore to support the satellite programme in 1982. The same year saw BEL achieve a turnover of Rs.100 crores.
In 1983, an ailing Andhra Scientific Company (ASCO) was taken over by BEL as the fourth manufacturing Unit at Machilipatnam. In 1985, the fifth Unit was set up in Chennai for supply of Tank Electronics, with proximity to HVF, Avadi. The sixth Unit was set up at Panchkula the same year to manufacture Military Communication equipment. 1985 also saw BEL manufacturing on a large scale Low Power TV Transmitters and TVROs for the expansion of Doordarshan's coverage.
1986 witnessed the setting up of the seventh Unit at Kotdwara to manufacture Switching Equipment, the eighth Unit to manufacture TV Glass Shell at Taloja (Navi Mumbai) and the ninth Unit at Hyderabad to manufacture Electronic Warfare Equipment.
In 1987, a separate Naval Equipment Division was set up at Bangalore to give greater focus to Naval projects. The first Central Research Laboratory was established at Bangalore in 1988 to focus on futuristic R&D.
1989 saw the manufacture of Telecom Switching and Transmission Systems as also the setting up of the Mass Manufacturing Facility in Bangalore and the manufacture of the first batch of 75,000 Electronic Voting Machines.
