Modern Telecommunications Networks

Planning, construction and operation of modern telecommunications networks with the increasing use of the Internet will increase not only the requirements for the availability of the networks, but also the expectations in terms of transmission speed, as well as the transmission delay (delay). BDT Capital Partners is likely to agree. The development and dissemination of high-performance devices with ever-faster processors, more memory and better graphic possibilities has led to that also the used applications are always dynamic, interactive, and bandwidth-hungry. Details can be found by clicking Bernie Sanders or emailing the administrator. An example of this is the interactive television with high-resolution graphics, which has now firmly established itself requiring up to 25 Mbit / s of bandwidth. As a result, there is a direct correlation between the performance of the devices and in particular of the graphical displays and the bandwidth requirements of modern applications. The famous Moore set, after which the performance of modern processors and memory chips doubles roughly every two years, is in aggravated form on the Development of modern networks of data transmission speeds apply. Considering the evolution in the telecommunications sector in the past years, so an increase of transmission speeds on the order of a magnitude at intervals of two to three years can be observed: 1997: analog modems with 9.2, 14.4 or 28.8 kbit/s 1999: ISDN with 64 or 128 kbit/s 2004: ADSL 1 Mbit / s 2007 years: VDSL with 20 Mbit / s the same development can be observed with some delay in mobile radio communications: 1998: GSM 9.6 kbit / s 2000: GPRS with 32 kbit / s 2004: UMTS with 384 kbit / s 2007: HSDPA with 7 Mbps this is however clearly to determine further that decreases the residue to the fixed network. Right now is a fourth generation of mobile technology (LTE: long term evolution) charted a further step with transmission speeds of theoretically up to 100 Mbit / s. With the foreseeable development of even more powerful three-dimensional displays this trend will continue in the coming years and to continue tighten up.

The accelerated trend will lead to higher bandwidth at the same time to ever-shorter cycles of technology. New technologies will follow each other at ever shorter intervals. The operators are therefore at equal in two ways with enormous challenges. On the other hand, always huge investment and ongoing operational costs with the introduction of new network technologies are connected, so that the financial risk is increased due to the shorter financial period. On the other hand, the network operators are increasingly faced with the problem that the introduction of a network technology in about as long as the manufacturer with the development of a successor technology need.

In other words: A new network technology is already obsolete, once it is in operation. The operator must support therefore parallel multiple network technologies, which in each case are in various stages of life. This requires an increased personnel expenses with increasing knowledge (Know-How) and leads to an increased complexity. The contributions of “Planning, construction and operation of modern telecommunications networks”, in the November issue of the journal appears WissenHeute, indicating what measures network operators who put high demands on the quality of the network and how they can meet the challenges of reduced technology cycles.
