DATAKOM expands its product portfolio in the area of PSTN, IP and mobile networks Ismaning, October 20, 2009 that DATAKOM GmbH has the distribution rights for the product line of the company (MuTech) Mutina technology srl, Italy, ubernommen with test and measuring systems of Mutina. Mutina is a manufacturer of test and measurement systems for PSTN, IP and mobile networks. Innovative solutions are designed for IP convergence of networks and applications. The analyses include the transport, control and user plane. For analyzing and correlating the quality of service (QoS), as well as the QoE (quality of experience) of triple – and QuadruplePlay applications, MuTech developed its own protected process ASDRsTM (application service detail records), which are integrated in addition to the established standards in the modular product line. The groundbreaking system architecture combines the monitoring and troubleshooting across all networks, regardless of the topology (E1, SDH/SONET, 100 / 1000 Mbps Ethernet and 10 Gigabit Ethernet).

The range of the analysis includes both Data applications such as also IPTV, VoIP in IMS, NGN, 3 G/4 g. The integration of NetFlow extends the monitored network area. The product line consists of appropriately scalable hardware platforms and software applications. They range from the handheld tester for the troubleshooting site (IPXPlorer one) on network-wide distributed Messprobes (IPXPlorer-mod /-Flex) to the central management (QXManager). The application packages include protocols and services for IP-core, IP data, multimedia, access, NGN, mobile IP and SS7 and IMS. The performance of the product line is the measurement hardware (IPXGIG4KTM). So can pro session, call transaction be provided and monitored to 4 Gbps without packet loss and detailed information. The content addressable memory and FPGAs, inspection and filtering in real time take over, also contribute to increase the performance. Mutina technology has a patent on this measurement card. A further patent was granted Mutina for the ASDRTM correlation procedure.

If TV is mobile. What is Cellphonetv anyway? Cellphonetv refers to television, that is received via a mobile device E.g. a mobile phone. All too easily equates it with WEB-TV. This refers to TV programs on a Web page, you can watch a live stream or optionally as a download from an Internet recipient. Although nowadays, almost all mobile phones are equipped with an Internet connection and & comparing acceptable screen resolution and sound quality to use video features comfortable, nbspbieten also this with Cellphonetv this has some disadvantages.

One would have the costs incurred, once one is mobile dialing in via a network such as UMTS in the Internet. Package deals are still far less common in the mobile sector and compared costs consuming than Internet flat rates for leased lines. Also own Mobilfzunknetze from technical reasons not particularly to the for the transmission of television programmes, because they connect a 1-to-1. That means everyone Participants can simultaneously send and receive. That sounds at first glance good causes but that the usable bandwidth among all active network participants must be notified. & nbspThe number of participants is therefore & nbspbeschrankt. Therefore, it developed targeted radio transmission networks for Cellphonetv – first DMB (digital multimedia broadcasting) and after that DVB-H (digital video broadcasting – handheld).

When broadcasting a signal, emitted exactly as in the well-known television, uniformly to all participants, without the number of recipients affects the transmission capacity. However, no return channel available is the recipients. For interactive television services, the mobile networks claim necessary then as before. & can be nbspAusserdem only broadcasts streamed over radio networks, which dials the user in a continuous television. A delayed offer is, however, technically impossible. Is currently in Europe a large-scale DVB-H network installed. For a fee of approximately 5 to 10 euros per month, you can receive up to 20 TV channels mobile. The reception via DVB-T is an additional opportunity for mobile television. DVB-T & nbspist & nbspin the vast majority cities available. Long time DVB-T was regarded as too power-hungry for batteries of mobile phones. Meanwhile, there are also mobile phones capable of receiving DVB-T. Leo Ahrendt
