System Integration & Technology Distribution (S&T) has announced in a press release that it has completed the implementation of a Dense Wavelength Division Multiplex (DWDM) network for Ukrainian GSM mobile operator Kyivstar. The ‘multi-million dollar’ contract was awarded in August 2006 and included the planning and installation of a nationwide backbone network with 120 nodes – the largest of its type in Ukraine. The new backbone multiplies Kyivstar’s capacity by a factor of eight, up to 320Gbps, meaning that more than four million subscribers can be served simultaneously per network segment. The system is designed to be flexible to cope with increases in traffic and expansion of non-voice services.
Kyivstar, which had 23.3 million mobile subscribers at the end of June 2008, owns a GSM network covering 99% of the population. Rapidly increasing demands on its infrastructure prompted the operator to place the national DWDM order, after seeing subscriber numbers jump by 6.7 million in the twelve months to mid-2006 alone, rising average duration of calls and users demanding improved service quality and more advanced mobile internet/data services. A Kyivstar spokesperson said of the completed project that ‘it has secured for a long time the capacity required for further dynamic growth.’
