	Radio-Access Network
	By Christian Bartsch
	Businesses expand and need to spread over to several buildings with some disadvantages. In some cases the distance between buildings is not as bad as it might seem but laying cables can be tricky. technical topics as such are possible to be solved in the mind but often other factors block cheap and cost wise solutions. Governments, city councils, property owners and other stake holders might be a hinderance. Sending data via air can help but opens up new hot spots. Security is one of these headaches as hackers can intercept data or even try to enter your network via this solution. Appropriate measures and consulting help to set up a fast and reliable network bridge. Inside rooms and short distances a solution can range from 300$ and go up to 1000$ but if you move on to larger networks and greater distance you require different technology. The basic solutions such as offered by differerent manufacturers are said to blast waves at a level of 5% of that blasted by a mobile GSM phone. So up till now health risk is by far lower than from overdoing mobile phone consumption.

The different technology offered will be presented to you here with several stratigic guides: Imagine if you could see into the Future Advanced Smart Technology Leader. You could gain new ideas and discover innovative solutions. You'd be more inventive, creative -ahead of everyone else. SAMSUNG offer a seamless migration to the new standard of wireless technology. Their integrated voice & data network provides all of the service and applications, which makes CDMA2000 possible. No other solution is as time or cost efficient. The Market for CDMA wireless equipment is centered on the Americas and Asia and represents 18 ~ 22% of overall wireless network demand. SAMSUNG Electronics developed the modem chip for out base transceiver stations, helping to improve competitiveness and laying the groundwork to launch the world first commercial CDMA2000 1X network in Korea. Now that the network equality has been technologically proven, they aim to expand exports of CDMA2000 1X, dominate the domestic CDMA2000 1xEV-DO networks overseas. The CDMA2000 1xEV-DO system supports ubiquitous and seamless data services and various other high-capacity multimedia services that help to improve the quality of people?s lives. It also increases demand for mobile internet connections which will generate new revenue for service operators approximately three times their investment. Once CDMA2000 1X is established overseas, Japan is expected to lead the adoption of CDMA2000 1xEV-DO to promote mobile internet and data services. Japan will then be followed by the US as well as China, India and other Asian nation. SAMSUNG, meanwhile, is securing a top-tier position in the global CDMA market by being the first to market the CDMA2000 1xEV-DO. A Core SAMSUNG strategy is to build a CDMA belt around the Pacific Rim linking nations that have adopted the CDMA standard. Along with its backwards compatibility, CDMA2000 offers a smooth and seamless migration path to the future system. SAMSUNG' s architecture supports both 2G and 3G cdma standards, giving carriers flexibility in implementing high-speed data services and providing up to twice the voice capacity of 2G systems. An established platform forms the basis of the network, along with a layered structure that means it is easy to introduce new services. Because SAMSUNG is so closely involved at every level of the CDMA2000 development from handset to network infrastructure, we can deliver a standard development for your network system and be there to support customers who desire the latest developments. For Network operators familiar with CDMA features, CDMA2000 brings a host of added benefits. It offers double the voice capacity compared with existing IS-95A/B systems. It has a high speed data service which is being designed to offer speeds of up to 153.6kbps. A special quick paging channel will mean longer battery life. However, a key feature is the backward compatibility with IS-95 A/B through the same spectrum allocation. Future product innovation will be developed for SAMSUNG' s mobile services with 1x EV-DO, 1xEV-DV and other advanced technologies.

	from above picture you can get an idea of different applications posible with such strong solutions. One key concept covers sales reps travelling about Australia having to access a major businesses sales and logistic system by phone, notebook or even wireless pda. By investing in a sales supporting solution you can improve the customer service and improve marketing effects as sales reps can sell their goods in a more appealing way. Solutions now a days offer notebooks access via phone into free-call lines offered by the business. This has a disadvantage as it can only be a local solution with vast cost bombs ticking away. This solutions is most often put in connection with RAS solutions. Major firms have taken towards VPN to get rid of their costly phonelines and to offer a global solution via the internet. This is by providing a tunnel from the local notebook into the internet along to the central computer. Onthe way their the tunnel must cross several security risks and make its way ast firewalls. By adding a second tunnel security is improved but users can get annoid as some sulutions lead to complicated logon procedures confusing people. Speed is here a key point. Remembering a conversation with a traveller in 1996 in Sydney. I can still notice that australia has comparative advantage to other countries. Wide bare ranges, distances to be overcome with no one in between. Some cities just bare 150.000 citizens but need fast communication. Families like to keep in contact and business people are travelling upto 40 times a year compared with europe where the general business man travelles 5-10 times. Asia is close by and offers access to opportunities. In europe you can sit in a london train and find ony one person not using a mobile phone. This shows that we are not looking a general toy for Australia and Asia. Wireless solutions offer some of the best ways to add flexibility to a businesses procedures. Time to market can shorten with teams working in their prefered optimal environment. Recruiting top engineers can no longer pull along with offers in conjunction with high pay. People want to work in their area close to family or where the weather is better for them. Take this article as an insight in to following articles. Glossary: Access Network Access Network, a network providing wireless interface with mobile terminals, consists of BSC, BTS, GAN, BSM. Base Station Transceiver(BTS) BTS, a system performing wireless interface with mobile terminals, exchanges wireless data and signal data with mobile terminals pursuant to the standards of IS-2000. BTS transmits the data and the signal data received from mobile terminals to the core network through BSC, and conversely transmits the data and the signal data received from the core network to the mobile terminals through BSC. To play these roles of a wireless transceiver, BTS performs functions of wireless resource management, RF scheduling and power control. BTS in the CDMA2000 1X. Base Station Controller (BSC) BSC is a system performing call processing, controlling BTS and providing interface with the core network. It also performs a function of redirecting the packet data call from a mobile terminal to the DCN network in the CDMA2000 1X network. BSC processes calls, SF (Selector Function) and RLP (Radio Link Protocol), and controls BTS in both of the CDMA2000 1x network. Base Station Manager (BSM) BSM is an operation terminal supplying operator interfaces for control and management of BSC and BTS. BSM provides commands for operation and maintenance of BSC and BTS systems such as inquiry of system fault/state/performance information, system shape management and system parameter control. BSM operates on commercial workstation platforms, and is implemented with GUI for easy understanding and control of the system state. Data Core Network The data core network is a network supplying packet data communication services to mobile subscribers, and consists of Packet Data Serving Node (PDSN), Home Agent (HA), Authorization, Authentication and Accounting (AAA), Network Management System (NMS), Foreign Agent Control Node (FACN), HA come Agent Control Node(HACN) and Total Control Manager (TCM). Packet Data Serving Node (PDSN) PDSN is a system connecting AN with DCN in the CDMA2000 1X network or the CDMA2000 1xEV-DO network, and interfaces with terminals through setting link layers. PDSN acts as FA for HA to supply mobile IP services. PHome Agent (HA) HA is connected with other networks or private networks to allow mobile IP users to access Internet, and exchanges data with FA (PDSN) through different encryption methods. Authorization, Authentication and Accounting (AAA) AAA is a server performing authentication and exercises authority for the packet data communication service subscribers, and billing functions for service usage. While AN-AAA performs authentication for subscriber terminals, AAA performs authentication for subscribers. Network Management System (NMS) NMS is a system performing operation and maintenance of the DCN components. NMS can remotely interface with the SNMP protocol, and can be operated by network suppliers or service providers upon demands from users.
