The Remote OMT Over IP is used to remotely perform OMT functionality from a TCP/IP network connecting BSCs. The Remote OMT Over IP is mainly used for: Getting detailed information about an RBS 2000 - The information can be used to remotely verify that an RBS 2000 is correctly configured and to perform preventive maintenance. Fault localization of an RBS 2000 - Experts can use the Remote OMT Over IP to perform fault localization and to guide service personnel at site Restart of a whole RBS 2000 or a part of an RBS 2000 - The same type of restart that is achieved by pushing a reset button in an RBS 2000 can be performed with the Remote OMT Over IP. This may be useful in situations with abnormal RBS behavior Retrieve detailed information about an RBS 2000 remotely from a TCP/IP network connecting BSCs. Perform fault localization of an RBS 2000 remotely from a TCP/IP network connecting BSCs. This means that it will ...

WiMAX is one of the hottest broadband wireless technologies around today. WiMAX systems are expected to deliver broadband access services to residential and enterprise customers in an economical way. Loosely, WiMax is a standardized wireless version of Ethernet intended primarily as an alternative to wire technologies (such as Cable Modems, DSL and T1/E1 links) to provide broadband access to customer premises. More strictly, WiMAX is an industry trade organization formed by leading communications, component and equipment companies to promote and certify compatibility and interoperability of broadband wireless access equipment that conforms to the IEEE 802.16 and ETSI HIPERMAN standards. WiMAX would operate similar to WiFi but at higher speeds over greater distances and for a greater number of users. WiMAX has the ability to provide service even in areas that are difficult for wired infrastructure to reach and the ability to overcome the physical limitations of traditional w...

Wi-Fi stands for   Wi reless   Fi delity. Wi-Fi is based on the  Institute of Electrical and Electronics Engineers' (IEEE) 802.11 standards  Wi-Fi has become the defacto standard for   last feet   broadband connectivity in homes, offices, and public hotspot locations. systems can typically provide a coverage range of only about 1,000 feet from the access point. Wi-Fi offers remarkably higher peak data rates than do 3G systems, primarily since it operates over a larger 20MHz bandwidth, but Wi-Fi systems are not designed to support high-speed mobility. One significant advantage of Wi-Fi over WiMAX and 3G is the wide availability of terminal devices. A vast majority of laptops shipped today have a built-in Wi-Fi interface. Wi-Fi interfaces are now also being built into a variety of devices, including personal data assistants (PDAs), cordless phones, cellular phones, cameras, and media players. The WiFi standards define a fixed channel bandw...

LTE refers to the advanced version of LTE that is being developed by 3GPP to meet or exceed the requirements of the International Telecommunication Union (ITU) for a true fourth generation radio-communication standard known as IMT-Advanced. 4G LTE, whose project name is LTE-Advanced, is being specified initially in Release 10 of the 3GPP standard, with a functional freeze targeted for March 2011. Following is the Key Features for LTE Advanced: §   Peak data rates: Downlink – 1 Gbps and  Uplink – 500 Mbps. §   Spectrum efficiency: 3 times greater than LTE. §   Peak spectrum efficiency: Downlink – 30 bps/Hz; Uplink – 15 bps/Hz. §   Spectrum use: the ability to support scalable bandwidth use and spectrum aggregation where non-contiguous spectrum needs to be used. §   Latency: from Idle to Connected in less than 50 ms and then shorter than 5 ms one way for individual packet transmission. §   Cell edge user throughput to be twice that of LTE...

Liquid Radio Liquid Radio - Making radio networks active, adaptive and aware Liquid Radio architecture shares resources such as antenna information across a broad area of the network, as well as balances traffic evenly over different bandwidths. It allows radio coverage and capacity to flow to wherever users need it most. Liquid Radio also enables operators to seamlessly integrate 3GPP radio access with Wi-Fi to use unlicensed spectrum.  Liquid Radio improves network efficiency by boosting capacity, balancing loads, enhancing QoS, raising uplink capacity for smartphones, and identifying and avoiding smartphone signaling. It also adds small cell capacity and unifies heterogeneous networks, as well as implementing award-winning self-organizing network (SON) functions to simplify network operations. High energy efficiency is achieved by low power consumption, integration of Rf to the antenna, minimized Rf losses and by an adaptive and cognitive radio network that ca...

An active antenna is an antenna that contains active electronic components. remote radio head (RRH) or antenna-integrated radio designs place the Rf module next to the passive antenna to reduce cable losses Active Antenna system is developed by Nokia Siemens Network (NSN) to reduce network cost and increase network efficiency. It’s a smart antenna and beam is driven by software. Active Antenna does not need to be merely passive elements. With intelligent integration, active antenna technology transforms traditional antenna to contribute to base station efficiency. This enables operators to significantly increase the capacity and coverage targets set for their network. Active Antennas are highly flexible and can meet the needs of many scenarios. They also support rising feature complexity including higher-order MIMO and receiver diversity, while retaining a simple and compact form factor. §   Carrier-specific tilting §   System-specific tilting §   Multi...

Paging process in WCMDA or HSDPA system is called WCMDA Paging. The Paging Channel (PCH) is a downlink transport channel. The PCH is always transmitted over the entire cell. The transmission of the PCH is associated with the transmission of physical-layer generated Paging Indicators, to support efficient sleep-mode procedures. Paging Channel selection System information Block Type 5  (SIB 5)  defines common channels to be employed in Idle mode. The UE may use Discontinuous Reception (DRX) in idle mode in order to reduce power consumption. When DRX is used the UE needs only to monitor one Page Indicator, PI, in one Paging Occasion per DRX cycle. The Paging Indicator Channel (PICH) is a fixed rate (SF=256) physical channel used to carry the paging indicators. Paging Procedure: Basically two types of Paging Procedures in WCMDA Paging. 1) Idle Mode Paging 2) Dedicated Mode Paging Idle mode paging  is used when UE is in idle mode so we can say ...
