It is no secret that cutting costs improves bottom line. Reducing energy consumption is a good way to lower operational expenditure, which is good news for telecom operators as they are among the topmost consumers of electricity in many countries. Rising energy prices and the global importance of deploying energy-efficient solutions indicate that everything is to be gained by making the most of new technologies that can reduce energy consumption.
Ericsson employees have been sharing their expertise in our technology journal for nine decades now. Celebrating 90 years in publication, Ericsson Review is one of the longest-running technical journals, providing insights on significant developments in telecoms technology. With a global understanding of the telecom industry, our experts aim to share their knowledge of building high-performance networks for the Networked Society and how current research is shaping the future and addressing the constantly changing challenges.
Over the past decade, the number of security attacks on IT and communications systems has risen drastically and as a result, security assurance has become a central issue for network operators and the telecommunications industry. Using a security assurance methodology at every stage of product development, vendors can show that the implementation of security assurance protocols in their products is accordance with agreed guidelines.
Putting the network in control over whether or not a device should switch to and from Wi-Fi, and when it should switch, will make it easier for operators to provide a harmonized mobile broadband experience and optimize resource utilization in heterogeneous networks.
When two large companies merge, it often takes a while – years in some cases – before processes get redesigned to span all departments, and the new organization settles into a lean and profitable machine. And the same is true of OSS/BSS. These systems have been designed for two different purposes: to keep the network operational and to keep it profitable. But today’s demanding networks need the functions of both of these systems to work together, and to work across the varying lifecycles of products and services.
There are many factors that have contributed to the extensive use of fiber in telecom networks. As a result of the bandwidth and speed it can offer per dollar spent, the use of fiber is becoming more extensive being pushed deeper and deeper – particularly in the last mile. In a field trial carried out by Ericsson and Telstra, technologies to meet operator demand for seamless upgrade of networks were put to the test.
The concept of self-organizing backhaul networks is not yet as widespread as the concept of SON in the context of radio-access networks. There are, however, ways in which backhaul networks can benefit from SON technology and delay investment in new architecture.
As HSPA evolution continues to address the needs of changing user behavior, new techniques develop and become standardized. This article covers some of the more interesting techniques and concepts under study that will provide network operators with the flexibility, capacity and coverage needed to carry voice and data into the future, ensuring HSPA evolution and good user experience.
Just a couple of years ago, the concept of allowing third-party access to operator assets was practically unheard of in the telecom industry. Today, the picture is quite different. Service exposure is about to create a whole new set of business possibilities for operators, developers and content providers.
