Calnex Solutions designs, produces and markets test instrumentation and solutions for network synchronization and network emulation, enabling our customers to validate the performance of the critical infrastructure associated with the telecoms networks.
We have established a position at the forefront of the test and measurement industry, providing our equipment to the world's telecoms network operators, network providers, systems suppliers, laboratories and network infrastructure. To date, we have secured and delivered orders from over 600 customer sites in 68 countries across the world.
Founded in 2006, we are headquartered in Linlithgow, Scotland, with additional locations in Belfast, Northern Ireland, Stevenage, England and California in the US, supported by sales teams in China and India. We have a global network of partners, providing a worldwide distribution capability. In 2015, Calnex was awarded the Queens Award for Enterprise for International Trade, recognising our international reputation for innovative products and global sales achievements and in 2020 we were named “Exporter of the Year” by the China-Britain Business Council at the China-Scotland Business Awards.
What are Network Synchronization and Network Emulation?
In order for mobile networks to work correctly, mobile radio transmitters, known as ‘basestations’, have to be synchronized to other nearby basestations where their coverage footprints overlap. This synchronization was initially achieved by frequency (each basestation transmitting on a slightly different frequency to those of adjacent basestations), and then moved to a time based approach, where each basestation is allocated a different slot of time each second to transmit. To deliver this synchronization between basestations, all equipment within the network has to conform to certain frequency and/or time transfer standards which define the accuracy of performance. Measuring accuracy and precision to less than 0.000000001 of a second is now required to ensure that network timing and synchronisation meets international standards.
The ability to carry out effective synchronization testing continues to be critical to measuring network performance, and will grow in importance with the evolution to 5G. We have evolved our test capabilities alongside developments in the synchronisation sector and have a range of sophisticated products to perform synchronization testing.
Network emulation is the process of using test equipment to replicate network behaviour under certain real-world conditions. In the telecoms industry, network emulation allows equipment vendors to verify the performance of their equipment under a range of network conditions, in particular during the design validation phase.
Our network emulation products are designed to impair data traffic for the development of Ethernet Switches and Routers for deployment in large data Wide Area Networks, operated by both the traditional network operators and in data storage farms offering cloud computing services.
The Evolution of the Telecoms Market
The global telecoms networks have evolved dramatically over the last 40 years and the challenges currently facing the telecoms industry are significant. These include the mass roll out of 5G networks, which will be essential for the realization of anticipated Smart Cities and Internet of Things (IoT) revolutions. The 5G vision for the telecoms infrastructure is extremely complex and will see a long-term transformation of the telecoms market, creating the need for test and measurement equipment to prove that new systems operate effectively and conform to rigorous international standards.
