Protection of cell sites (4G/LTE)

  With the commercial introduction of UMTS technology in 2003, mobile data communication gained in importance besides voice communication. As the demand for data volumes grew, so did the global demand for bandwidth. The increasing use of smartphones and other mobile terminal equipment has lead to a significantly higher utilisation of existing conventional mobile networks. […]

Connecting to and communicating with a video wall

  A video wall consists of an integration of multiple ultra-thin bezel LCD or rear projection digital light processing (DLP) displays tiled together contiguously or overlapped to form one large logic screen. This produces a high quality image on a vast pixel estate resulting in a superior human-machine interface through effective communication with the video […]

EMI shielding effectiveness in conductively coated plastics

  Conductively coated plastics are becoming increasingly popular for EMI shielding. Vacuum metallising is a cost effective way to get fast turnaround in small quantities. Commonly, shapes can be complex, making it impossible to get absolutely uniform coatings. The article covers comparative shielding effectiveness (SE) tests on various configurations, primarily to assess the impact of […]

Super-broadband speeds – it’s all in the chip!

  The first deployment of the Infinera DTN-X platform across South Africa will deliver businesses with the simplicity, scalability, and efficiency expected from a fibre network – and it is all in the chip!
