Integracja rozwiązań dla instalacji telekomunikacyjnych i operatorów kablowych

WWK ALPHA 2 is an advanced, digital multi-band amplifier designed for professional SMATV antenna installations and complex individual installations. The device enables selective processing of DVB-T/T2 signals in the VHF and UHF bands, integration of DAB and FM signals, as well as cooperation with external modulators and headends via the AUX input.

The DSP platform used allows for precise adjustment of the level of each multiplex, channel conversion within the band, automatic gain control (AGC) and effective reduction of intermodulation distortion. The amplifier is equipped with advanced LTE/5G filtering (including a SAW filter for the 5G 700 band), intelligent power control of antenna preamplifiers and an automatic signal search function (SMART SCAN).

WWK ALPHA 2 ensures stable operation even in difficult reception conditions, with large signal level differences and high LTE and 5G emission density, meeting the requirements of modern collective and facility installations.

WWK Alpha 2 is another Polish product that has been created with your needs and experiences in mind. It is 100% ready for collective installations in accordance with the MTBiGM regulation. Developed for optical and traditional installations.

Application scenarios – WWK ALPHA 2

1. Collective installations in multi-family buildings

WWK ALPHA 2 enables selective processing and equalisation of DVB-T/T2 signal levels received from different directions. Thanks to channel conversion and precise level adjustment, each multiplex can be adapted to the requirements of the installation, ensuring stable reception in all subscriber sockets.

2. Commercial facilities: hotels, guesthouses, schools

The device allows the integration of DVB-T/T2, DAB and FM signals in a single installation. The broadband DAB mode enables the distribution of digital radio without the need for channel programming, and high resistance to overmodulation guarantees reliable operation in complex networks.

3. Installations in difficult reception conditions

In locations with large signal level differences and LTE/5G interference, WWK ALPHA 2 stabilises signal parameters thanks to LTE filters (including SAW for the 700 MHz band), automatic gain control and high resistance to intermodulation.

4. Modernisation of existing SMATV installations

WWK ALPHA 2 works well as a modernisation element in older antenna installations. The SMART SCAN function allows quick searching for available multiplexes, and digital signal processing allows the installation to be adapted to the current frequency plan without replacing antennas and cabling.

5. Integration with modulators and headends

Thanks to the AUX input, the amplifier can work with external DVB-T/T2 modulators and small headends. This allows for the construction of hybrid TV signal distribution and information service systems in public facilities.
