SHENZHEN, China -- Huawei, a leading global information and communications technology (ICT) solutions provider, today announced the launch of a UMTS HetNet (Heterogeneous Network) Macro-Micro Co-Carrier Network solution that increases network capacity up to four times. The solution features the rational planning of macro-micro spatial positioning and same-frequency carrier usage for macro and micro base stations to significantly alleviate network traffic pressure in high-traffic areas. This ensures that users have free-flowing access to mobile broadband services in even the busiest hotspots anytime, anywhere.

The increasing diversity of mobile broadband services and growing smartphone penetration have resulted in massive data traffic growth. In crowded hotspot areas, such as shopping malls, event sites and commercial streets, large groups of people making calls and consuming data traffic in the same area at the same time leads to network congestion. This can make it difficult to provide basic communication services and consistent user experience. Making use of existing spectrum resources to enhance network capacity and ensure user experience is increasingly becoming a bigger and bigger challenge for operators to face. Huawei’s UMTS HetNet Macro-Micro Co-Carrier Network solution solves this challenge through the rational planning of macro-micro spatial positioning and same-frequency carrier usage for macro and micro base stations.

UMTS networks typically suffer from self-interference service interruptions in spots where two sites cover the same area with the same frequency. The rational planning of spatial positions between macro and micro base stations, however, makes use of a unique “Dynamic Sensitivity Control” algorithm to flexibly and effectively enable macro-micro base station coordination on the same frequency. This eliminates interference and significantly increases network capacity.

A CSP's digital transformation involves so much more than technology. Crucial – and often most challenging – is the cultural transformation that goes along with it. As Sigma's Chief Technology Officer, Catherine Michel has extensive experience with technology as she leads the company's entire product portfolio and strategy. But she's also no stranger to merging technology and culture, having taken a company — Tribold — from inception to acquisition (by Sigma in 2013), and she continues to advise service providers on how to drive their own transformations. This impressive female leader and vocal advocate for other women in the industry will join Women in Comms for a live radio show to discuss all things digital transformation, including the cultural transformation that goes along with it.
