Try MVDS Technology at Your Area: City1 TV TestKit is Offered at Promo Price

Deployment of 40.5-43.5GHz Multipoint Video Distribution Systems (MVDS) might be a good business expansion idea for the new competitors of the old established telecom operators while the liberalization trend plays its dominant on the world telecommunication market. The primary advantages of MVDS are rapid infrastructure deployment and the ability to provide on-demand content to local consumers. For a local Network Service Provider it can be significantly cheaper to install MVDS than a cable system since only homes requesting the MVDS services would be provided with receivers. From this view, MVDS can be applied as a supplement of the broadband Cable TV network (CATV), as a substitution of the CATV or Direct Broadcast via Satellite (DBS) or as a cable backbone alternative during the building up or extension of parts of a cable network.

To help local Network Service Providers to evaluate the competitiveness of MVDS technology on deployment of broadband multimedia and Internet services at their areas and check the performance of MVDS equipment, we announced the availability of City1 TV TestKit. The City1 TV TestKit is a promo-discounted demo kit, that intended for evaluation of Digital TV broadcasting mode of City1 system in a real field environment. It consists of one 150mW 90-degree sector base station and two client terminals with 30cm dishes. The guaranteed operating range of City1 TV TestKit tested for even heavy 5mm/h rain is up 9km.

To generate a test TV signal for further broadcasting, the TestKit included the Satellite receiver/Base station interface unit. This unit is included for test purpose only, or in other words, it allows to catch up one of the locally available satellite TV channel and transmit it to client stations at 42GHz. This ELVA’s equipment, together with standard satellite receiver and digital TV receiver is enough to test digital TV mode of City1 MVDS solution and check the transmission quality/performance rate. 

The City1 TV TestKit can be also tested for IP broadcasting. In this case IP-Encapsulator and DVB-S Modulator required to be added to the Kit. While ELVA's IP-Encapsulator is a standard shipment option, a potential customer of the City1 TV TestKit is free to choose any of third-party DVB-S Modulators that are widely available on the market.

52-85GHz Heterodyne Sweeping ECE Radiometer launched on TCV BR Tokamak

At our March 2002 Newsletter we reported the shipment of unique 52-85GHz Heterodyne Sweeping ECE Radiometer for Plasma Physics Laboratory of Applied Physics Department Institute of Physics – University of São Paulo (San Paulo, Brazil). This equipment was shipped as the result of our continued cooperation with this Brazilian customer since 1998, when ELVA's Multi-channel Interferometer was initially installed at the Tokamak site.

During summer 2002 time, our engineers visited customer site, taking part in radiometer tuning and in a series of plasma experiments. These were measurements at 52GHz to 75GHz on second harmonic of electron-cyclotron frequency. ELVA’s ECE Radiometer was used to register an evolution of frequency content emission at a mode of plasma heating by Alfen waves.

"Your visit to our laboratory was important. We are operating the machine in various regimes and everything seems to me working very well", - praised Prof. Dr.Ruy Pepe da Silva from Plasma Physics Laboratory.
