Even more difficult is the situation among the manufacturers of the equipment. In mid-January Nortel has filed for protection from creditors, in the last quarter Motorola suffered a loss of 3.6 billion dollars and a decrease in turnover from 9.65 billion USD in 2007 to 7.1 billion USD in 2008. Sony Ericsson, after a profit of 1.4 billion USD in 2007, recorded nearly 100 million USD loss in 2008.
Governments of the United States and European countries want to avoid at any cost bankruptcies of large producers and increase in unemployment levels. They develop programs that should counteract the tendencies. The first one will be American investment in the revitalization of the U.S. telecom market. The Barack Obama's stimulus package includes 6 billion dollars investment in the development of wireless and broadband Internet access and additional 11 billion dollars for the development of intelligent networks.
So far, in Europe there are no such actions in the field of telecommunications, however everyone is convinced that the UE, introducing new broadcasting technologies, at least will not repeat the mistakes of the high concession fees which drained the money earmarked for investments in GSM and UMTS networks.
An opportunity for Europeans and Americans is LTE technology. This is a technology in which European and U.S. firms have many advantages over Asian competitors, so starting the solutions on their own markets they may contribute to the overall success and improve the performance of both operators and manufacturers. Currently, the most powerful position in LTE have Sony Ericsson, Nokia Siemens Networks, Alcatel, Motorola.
LTE is already gaining momentum. At the beginning of February, Motorola has launched in Swindon, UK, the first test telecommunications network working in LTE (4G) technology. The network operates in the 2.6 GHz band. It simultaneously allows to make voice calls and perform data transmission in 4G technology. The estimated speed of data transmission is between 29 and 226 Mbps. In the U.S. market, commercial launch of LTE is announced by Verizon, for later this year.
LTE (Long Term Evolution) is being developed as a 4G standard, to improve the Universal Mobile Telecommunications System (UMTS). LTE is to increase the performance of the 3G UMTS packet service (based on TCP/IP protocol), with data rates over 100 Mbps. LTE wireless interface is based on OFDMA (Orthogonal Frequency Division Multiple Access) in the downlink and SC-FDMA (Single-Carrier Frequency Division Multiple Access) in the uplink. There are used QPSK, 16QAM, and 4QAM modulations. The standard efficiently supports multi-antenna technologies (MIMO).
In the next issue of DIPOL Weekly Review we will present a report on CeBIT 2009.
Did the last year's trends come true?
You may think of it after reading CeBIT 2008 report.
In one of the buildings there is seven-star hotel (there are two such hotels in the world - the other one is in Dubai). The price of accommodation in the Presidential Suite is 30,000 USD. Lunch in the restaurant costs from 600 USD upwards.
On the buildings that depict the Chinese dragon (this architectural shape can be seen here) there are 7 giant LED displays with a total area of 3,400 m2. The largest of the displays has an area of 900 m2.
At present, the largest LED display is also in Beijing, with size of 250 x 30 m.
The largest facade LED display is to be built in Dubai (100 m high).
In the case of such problems we advise to:
- use directional antennas and channel amplifiers, or
- use the dedicated steep CDMA filter R49603 before the first amplification stage.
After completion of this procedure the system is ready for operation. The configuration wizard and archive managing tool can be run any moment to update the configuration or reorganize the archives.

The distinguishing features of the devices include support for megapixel cameras up to 5 Mpx, multichannel preview and playback (simultaneously from all channels), audio recording, cooperation with all popular models of IP cameras.
They can operate autonomously using the embedded software - for regular operation they do not need to cooperate with PCs or use their resources. NUUO NVRs are used in all kinds of maintenance-free systems. Due to Linux OS, they ensure stable operation and resistance to computer viruses.
Such systems are suitable for surveillance of offices, warehouses, stores, businesses, various buildings etc., where the cost of hiring additional staff is unacceptable and automatic video recording provides adequate protection.

Network Video Recorder (NVR) - storage and management solution for IP CCTV system
The company management decided to modernize the existing wireless link that did not provide satisfactory stability of operation nor adequate throughput. The link connects the Grand Felix Hotel with the second Felix Hotel located about 500 m away.
Grand Felix has a 4Mbps DSL connection and two LANs. One of the LANs provides the guests (with the use of Access Points) with Internet access, the second LAN links computers at the reception desk, in the office, bars, telephone exchange etc. Stable connection with the second hotel allows to use another LAN there. The modernized system is based on ULTIAIR devices. It is a family of professional Access Points designed for long-term outdoor operation. They allow to create efficient wireless IP CCTV and ISP networks. ULTIAIR devices are characterized by short delays and high throughput. They can be managed via WinBox utility or telnet. The APs operate in unlicensed 5GHz band - no special permissions are needed.The RouterBoard with Mikrotik system has been put in outdoor housing of IP 66 class, which guarantees full protection against adverse weather conditions and corrosive environments (industry).
The modernization allows to increase throughput, improves stability and work comfort. Smooth operation of the network means fulfillment of design objectives - high stability and throughput of the wireless link.

- buildings with thick walls,
- cellars, basements (pubs, coffee shops etc.),
- underground parking lots/garages,
- steel construction buildings with metalized window panes,
- shop floors.

The idea of using GSM amplifiers/repeaters
The signal is received by the outdoor antenna, transmitted (via antenna cable) to the device,
amplified and retransmitted (with indoor antenna) to the GSM phones/terminals.
The signals from the phones/terminals go in the opposite direction.
ACTi is running a competition for the best video!!! ACTi Corp., the world's leader in IP CCTV solutions, has launched a competition for the best surveillance video captured with ACTi devices. In each category, the winner will get freely chosen model of megapixel ACTi camera. There are the following categories:..
