The SkyCell™ E1 Series of telecommunications products have been developed specifically for utilisation within the expanding GSM cellular market. The main utilisation of the products is as an interconnection between Micro Cellular hardware. Typical installations are between Base Station Controllers and Base Station Transceivers, and Base Stationer Controller to Base Station Controller. There are currently two formats of the SkyCell™ 2 Mb/s Series offering connection capabilities between 2000 and 4000 metres. Connectivity: The connection of the SkyCell™ E1 Series of products and the Cellular hardware is via balanced 120 UTP cable. This cable is connected directly in to the RJ45 socket situated in the SkyCell™ E1 Series interface. All data transmission is fully compliant with the ITU G.703 standard. If an unbalanced 75 coax connection is required, a BNC to RJ45 Balun is supplied on request Configuration: Due to the unique nature of the SkyCell™ E1 Series of products a seamless interconnection of Cellular hardware is achievable. All equipment operates at its full rated bandwidth and introduces near zero latency. Additionally, due to the nature of the technology utilised, there is no interruption of any clocking mechanisms nor is there any problems associated with earth loops due to the utilisation of UTP. Security: By utilising unique advanced error resistant coding within the full range of equipment manufactured, a highly secure connection is achievable which is transparent to RF scanners or spectrum analysers. Performance: The system offers an industry accepted performance availability figure, which, through field trials and independent laboratory testing, has achieved a continuous operational availability in excess of 99.1% to 99.9% within the UK and worldwide. All PAV systems have been designed to the highest specifications and offer a bit error rate greater than 10-10 during operational availability.
