| We introduce the latest super-high-speed wireless telecommunication system 'BARS-D'.
Its unique feature is data rate of 100 Mbit/sec realized by means of radio signal within super-high frequency band (microwaves). |
| 'BARS-D' applications
|
- Securing of wireless digital telephony, videotelephony, Internet communication, digital TV, and radio broadcasting.
- Creating of wireless super-high-speed intercept proof telecommunication networks having high protection rate within a radius of 30-50 km.
- Creating of the object control systems (data collection and exchange, servo-mechanism direction, cameras, sensors, etc.) within a radius of 30-50 km from each of the base stations, namely:
- Security, fire-prevention, road and other tracking loops of this kind.
- Product pipelines, highly spread industrial establishments, service systems like air ports, railroad tracks, etc.
- Creating of cellular communication base centres.
- Connecting end users with such servicing systems like:
- Ticket booking
- 'Bank-Client' system
- Distant education
- Ratings and questionings
- Inquiry and informational services, etc.
|
| 'BARS-D' advantages and possibilities
|
- Super-high data rate - 100 Mbit/sec per each radio channel used, allowing to service more subscribers within a time unit and making connection low cost.
- Rapid deployment of subscriber stations (no more than 4 hours).
- Low cost of subscriber stations (around 1500 USD), each allowing to service from 1 up to 100 end users - corporative subscribers (apartments, offices, departments of the companies, including videocameras, sensors, servo-mechanisms, etc.).
- Possibility to service up to 20 000 user stations by a single base station at a time (that is up to 2 million end users) at the area of 3000-8000 square meters (within a radius of 30-50 km).
- User station is an automated network administrator for the subscribers.
- Compatible to all existing informational networks (Internet, digital automated telephone systems (ATS), satellite communication systems, cable networks, cellular networks, etc.).
- High rate of data protection against unauthorized access (128-bit key, signal transmission by cut packages at IP-protocol, etc.).
- Low power consumption (40 Watt per 1 transmission channel, resulting in minimal capacity of base station, servicing the area of 3000-8000 square km, total 360 Watt).
- High level of environment safety (owing to the use of low radiating power - 0,05 Watt in microwave range).
- High noise immunity.
- Supplying end users with an array of services at a time:
- Digital telephone, videotelephone;
- Internet;
- Interactive TV;
- Video conference communication;
- On-line services ('bank-client', inquiry services, ticket booking, distant education, etc.).

| 'BARS-D' description and technical data
|
"BARS-D" operates in the range of ultrahigh radio frequency from 3 up to 30 GHz (equaling centimetric waves), transmitted within the limits of direct visibility.
"BARS-D" consists of base station and required quantity of subscriber stations. A single base station can transmit signals by directional sector (40) or circular (360) without distortions and interferences within a distance of 30 up to 50 km which depends on selected transmission frequency.
Base station can be linked to:
- high-speed Internet providers;
- telephone public networks;
- automated telephone stations (ATS) for long-distance calls;
- local TV and radio studios;
- any other telecommunication systems.
|
Subscriber station can service from 1 up to 100 corporative subscribers (end users).
The below table contains key technical features of 'BARS-D' system. |
