Sale and lease of microwave and laser communication systems

We provide microwave communication systems (or laser systems suitable for areas of high interferences) to interconnect the nodal points of your data network. In both variants, we can sell or lease the equipment. We operate Point-to-Point (PtP) radio communication systems both in licensed and free frequency bands.

Our services were already used by Vodafone Czech Republic a.s., UPC Česká republika s.r.o., Dial Telecom a.s., Magnalink a.s., Sauron CZ s.r.o., etc.

Services we offer:

Delivery of microwave radio communication systems (PtP type) for wireless connection in free and licensed frequency bands
Free frequency range – 10, 17, 24 and 80 GHz bands are used most frequently
Licensed range – 6, 11, 18, 26 and 38 GHz
Technologies: RAy, Alcoma, Siklu, Ceragon, fSONA Networks

Construction of radio communication systems

Radio communications are used in situations where optical or metallic cable lines cannot be laid for technical or economic reasons. When constructing such systems, we provide complete services from pre-design research, design, calculation, up to the construction of antenna arrays.

We have already built wireless communication systems for our prominent customers Vodafone Czech Republic a.s., T-Mobile Czech Republic a.s., České Radiokomunikace a.s., UPC Česká republika s.r.o., Magnalink a.s., and GTS Czech s.r.o.
