How does CTR work?
CTR technology is based on a single regular base station and multiple lightweight CTRs.
Single regular base station with signal retranslator
The base station with relaying of signals differs from the usual one by the presence of a relay unit from several additional transceivers with the conversion of frequency channels beyond the standard service band of subscriber stations.
On these channels communication with subsequent repeaters is ensured and the channel capacity is transferred to them.
Multiple lightweight base stations with Capacity Transfer Radio
CTR stations include an identical relay unit with capacity transferability, which can convert some of its channels into a standard band to serve subscriber stations.
And the rest is used to connect and transfer the channel capacity to the next repeater.
Where to use CTR?
Cost effective way to create network coverage for towns and villages placed away from the main infrastructure.
Network coverage with low energy consumption and easy maintenance.
Creating network coverage along and around roads and railroads.
Configure seamless network coverage along narrow pipelines as well as large and diverse landscape industrial complexes.
Construction of a base station
Regular base station
Heavy tower
Bulky antenna tower, in the upper part of which is mounted up to 6 blocks and antennas of radio relay communication, sector antennas, feeder cables - the total load on the tower is more than 800 kg.
Ground hardware room
Regular base stations need hardware racks, air conditioning systems, as well as other auxiliary equipment.
Powerful power supply
Regular base stations require expensive uninterruptible and powerful power supplies.
Long feeder cables
The placement of transceivers in a hardware room at the base leads to a significant loss of the signal for the cable connections. With a 80-meter tower, signal loss can be more than 3dB, which in turn leads to a 30% reduction in the coverage area.
CTR base station
Lightweight tower or mount on a wind turbine
Due to its small size and weight CTR is mounted on a less expensive lightweight tower or even a wind turbine.
No hardware room
The compact dimensions of the CTR makes it possible to mount its blocks directly on top of the antenna. So you don't have to rent premises and use containers.
No need for powerful power supply
CTR does not require a powerful or uninterruptible power supply, it can be operated with a normal power supply and an external battery.
No long feeder cables
In this type of installation, there are no long feeder cables. The insertion loss is completely eliminated and the range of service is significantly increased.
Expenses
CTR reduces the price up to 5 times. The load on the antenna tower will be less than 100 kg. This will allow easy installation of antenna masts and dramatically reduce costs.
Example of usage
An illustrative example of the economic effect is the example of covering the transport highways.
Estimated price — $1 155 000
Usually in the GSM network, base stations with 70m towers are installed at a distance of 20km from each other. To cover the area of 120km, seven base stations and equipment of seven radio relay flights are necessary. Estimated capital costs for the implementation of such a fragment is $ 1.155.000
Estimated price — $442 500
In the method proposed by us, the following components are located on the same site: one base station with retransmission, the equipment of one radio relay passage for communication with the controller and six repeaters with transfer of capacity on light antenna masts.
This method provides a channel capacity similar to the standard version. In the new configuration, capital costs will be $ 442,500, as opposed to $ 1,155,000 in costs when using conventional base stations.
