Fourteen Bulgarian companies from the ICT sector and Technical University – Sofia are partners in the cluster. The cluster has the tendency of expanding itself, as it is open for new members. The portfolio of the member companies covers almost the entire product range of telecommunication services. The member companies construct, produce, install and maintain competitive products. One part of them is made up of software products which find application in the field of modern telecommunication services: IP telecommunications, intranet systems, and specialised software. Other main fields the companies work in include development of telecommunication and network equipment, micro- and nanoelectronics, embedded systems, power supply devices and converters, security systems, access control and fire alarm systems, multiplexers, optical communications, etc. It is a part of the European Cluster Collaboration Platform(ECCP).

It has participated in the following support funded programme:
- CIP/COSME

The main advantages of Bulgarian Cluster “Telecommunications” can be seen in the design, development and maintenance of complex telecommunication networks, where the cluster’s experts most effectively combine products and solutions of leading international companies such as Cisco, Juniper Networks, Infinera, Microsoft, Schmid Telecom, R&M, MicroSens, SAGEM, ADC, RedHat with own equipment and software solutions – SDH/PDH Mux, intelligent gigabit switches, interface converters, integrated access devices – IADs, billing and accounting systems, voice recorders and many more.

The technical knowledge, skills and experience of the specialists who work for the BCT member companies include:
- Core network technologies – 3rd generation DWDM, SDH, PDH, ATM, radio relay systems;
- Access network technologies – xDSL, active Ethernet, FTTx, SDH/PDH multiplexers, cross connectors, interface converters;
- Full range of power supply systems - DC supply systems, DC-AC invertors, DC-DC converters, frequency converters, UPS systems, outdoor cabinets, special cooling solutions;
- Software solutions based both on platforms such as IBM, Microsoft, HP, Oracle, Apple, and on open source code platforms such as Linux/*BSD;
- Integrated solutions for the delivery of multimedia content for hotel systems;
- VOIP technologies;
- Softswitch technologies;

A huge part of the BCT member companies develop new competitive technologies, products and services. The cluster encourages this as it keeps close connection with education centres and institutes. As a cluster member Technical University – Sofia gives companies the opportunity to use specialised high-tech laboratories for the development of innovative products and technologies. BCT applies and participates in international projects for the development of the telecommunications sector, funded by European programmes. Thus the cluster members can successfully penetrate new markets and promote their activities. This is also how the main goal of Bulgarian Telecommunications Cluster to support the development of business and innovations within the Telecommunications sector by increasing the competitiveness of its member companies is achieved.
