TELECOMMUNICATION

Ensure you never lose connection

Communication is borderless. Telecommunication and IT regulation is not. A wide variety of laws and guidelines from different countries and telecom providers must be met before your products can enter new markets.

Access is just the start. To achieve market success, your products' design and usability must satisfy the end user's expectations. In an industry driven by innovation, consumer behaviour and expectations are constantly evolving.

GTL simplifies the entire process for you. We help you determine what your customers want and how you can best deliver that. We review designs and test specific target groups to provide information about your products' usability. We ensure the safety of electrical and electronic devices and components. When your products are ready to market, we certify your equipment for the appropriate standards. We can also manage communication with the relevant authorities on your behalf.

Our experts have specialist knowledge in key industries such as marine, aviation, defence, electronics consumer products, and communication technology infrastructure and equipment. They ensure you have the competitive edge and certifications to uphold it.
