Heterogeneous networks will create new revenue streams for operators through applications and services for the end-user and could even play a vital role in disaster relief
Traditionally, mobile network infrastructure relied on strategically placed macro base stations scattered in order to ensure appropriate coverage for customers. However, with the onset of new mobile technologies such as LTE, and given the growth in the number of smart phones, network planners the need to think outside the box, and rethink the traditional network topography.
Small cell deployments, whether pico- or femto-, and their role in a multilayered network is one of the themes of Avren Event’s 8th Annual Base Station Conference, and of much of the event portfolio for Avren Events. With over 22 international operators from all continents, and 40+ expert speakers from throughout the ecosystem sharing their views on heterogeneous networks, RAN planning, spectrum usage and acquisition as well as effective CAPEX and OPEX reduction strategies, the Base Station Conference will provide a unique networking and information-
SHAPING HETEROGENEOUS NETWORKS
Building a heterogeneous network is a focus for many operators looking to ensure wider coverage area without increasing CAPEX and OPEX. Ensuring seamless handover between cells, site design strategy and maintaining QoS for the end-user are the main priorities for operators around the world, and as a consequence, of the entire vendor ecosystem.
In densely populated urban areas, operators face the challenge of meeting the constant demand for data and voice services in congested areas such as stadia, malls or busy shopping malls. New developments in SONs, as well as DAS and “intelligent”
With the onset of LTE, and looking ahead to LTE Plus, operators and vendors alike must now think of how they are to equip their base stations to handle these new technologies without having to rebuild their entire infrastructure, and give an effective answer to the massive traffic that they will incur, while still maintaining service to 2G and 3G customers.
With live LTE deployments in Germany, Scandinavia, America and Asia, and further trials taking place in all continents, operators and vendors must work together to create efficient networks, however the challenge remains in working with multivendor sites and building antenna sites capable of handling all technologies.
Operators have also started to look at other alternatives to further their networks’ reach while maintaining their costs at a minimum, and joint ventures in network sharing have become a popular trend in the market. Companies such as Everything Everywhere in the United Kingdom serve as prime examples of the possible benefits of a network sharing agreement.
IMPORTANCE OF QUICKLY REESTABLISHING NETWORKS
However, multilayered networks don’t only play a vital role in network planning in established networks, but have been used in extreme cases such as disaster relief. In recent natural disasters such as the Christchurch earthquake, the Japanese Tsunami and the floods in HatYai in Thailand, operators have deployed femtocells on pick-up trucks to instantly reactivate the cellular network.
“We had great success in using femtocells as an alternative to reestablishing telecom services through a GSM femtocell,” explains Jesada Sivaraks, network engineer of TOT Thailand. “Given that most macrocells were offline due to power cuts, sometimes for several days, people found great relief and comfort when they were able to communicate with their friends and family instantly.”
Similar scenarios were deployed in Japan and New Zealand, adding to the thought that small cells with satellite backhaul can open doors in remote, untapped markets that still are unable to offer an established mobile network to their residents.
Small cells can also play a key role in monetizing networks and opening new revenue streams for operators. As Camillo Carlini of Telecom Italia told Avren at their recent Femtocells World Summit 2011, held in London, “With applications, small cells’ value proposition goes well beyond providing coverage. Your mobile phone can notify you remotely who is inside your home, or if you are in a mall, send a message directly to your handheld device informing you of special offers and discounts in your vicinity”.
Taking static networks and allowing them to communicate directly with the customer through their mobile phone is the next step forward for multilayered networks.
