"Every day one quarter of the world's population connects via Nokia Siemens broadband networks", says Nokia Siemens African region CTO Karri Kuoppamaki. Recently the company acquired Motorola's network division to capture new customers from Japan and North America markets.
Working with over 600 customers in 150 African they saw the need for improved intelligent mobile network architecture. This is as a result of broadband demand and the unpredictable nature of traffic flow for optimized capacity hungry mobile devices.
To help telecommunication network operators' deal with such future issues, Nokia Siemens's introduced the Liquid network solution to meet fluid demand for future broadband capacities. Liquid network solution allows for intelligent broadband management and baseband pooling. The solution helps to ease frozen capacities in telecommunication base stations and radio access sites.
Nokia Siemens Networks' Liquid Net is a new way to deliver broadband that can easily adapt to meet changing and unpredictable broadband demand, which -- globally - is predicted to increase 1000 fold by 2020, with the Zettabyte age of the Internet set to dawn by 2015. This makes more efficient networks essential in emerging telecommunications markets such as Kenya.
In short, this radical new approach is needed to respond to current broadband challenges by enabling telcos to achieve network capital efficiency and adapt to unpredictable future broadband demand.
According to the Communications Commission of Kenya (CCK), the country's total number of mobile subscribers increased to 25 million by June this year. This means that the current mobile penetration rate is currently at approximately 63%. The mobile penetration rate is expected to touch 75% by the end of 2015. Considering that, nearly 5 years ago, the mobile penetration rate in Kenya was only at 21%, simply shows the tremendous growth witnessed in the country.
Kuoppamaki comments that the mobile broadband rate (per 100 inhabitants) is currently at less than 9% and is expected to grow to 23% by the end of 2014. To meet the envisaged high demand, he said networks will need to tap into evolutionary solutions like Liquid Net which enables networks to self-adapt and meet the capacity and coverage requirements by sharing resources based on demand.
Liquid Net builds on the principles of Nokia Siemens Networks' Liquid Radio architecture, which self-adapts its capacity and coverage to match fluctuating user demand through baseband pooling, and adds Liquid Core and Liquid Transport functionality to the network.
The Liquid Radio architecture also offers Heterogeneous Networks, which enable all network layers to be used as a logically unified network. Another aspect of Liquid Radio includes Active Antenna System technology, which supports multi-radio and multi-band access for GSM, 3G, LTE and LTE-Advanced, providing up to a 65 percent gain in capacity.
