Are based on a temporal multiplexing and codes. Consequently, it is possible to realize the detector and to this end the TDD mode ensures a great protection as regards the noise emitted by other users. Certain radio parameters, such as the width of the band (5 GHz), and the modulation for phase shift stages a4 (MDP4) are common to both FDD and TDD.
Instead, the same are different for potential service and type of preferential service. And possible to have loans/ service potential that reach 2.048/ s in TDD mode, while the FDD will reach 384/ s in terms of best recharge price current usage. Due to its characteristics, the UMTS radio interface is presented as the ideal device to satisfy the needs of end users and operators.
The terminal communicates with the UMTS access network UTRA via the radio interface. The access network is constituted by such as node B (which can be compared to the GSM base station), connected to a radio network controller (RNC) similar to a GSM base station controller through the interface. An RNC controls mobile recharge api the different nodes B.
The mobile recharge api interface, absent in GSM, is a consequence of the CDMA radio interface technology. Interface links the access networks and basic. The radio interface is an open interface for all network elements.
An open interface (like interface A GSM) promote competition in the infrastructure market. However, since the system is intended to be used in Europe, Asia (including Japan) and the United States, where basic networks follow different routes evolution, you will have a set of standardized functions with the interface instead of having a single best recharge price interface. An open interface will allow network mobile recharge api operators to interact UMTS equipment Node B and RNC from different vendors.
While the introduction mobile recharge api of the technologies CDMA and UMTS radio access ATM differs from access GSM radio, the architecture of the basic network will be an evolution of the system under the GSM network and will allow you to migrate from existing networks.
The network architecture of UMTS base and its evolution are based on two principles: the need to preserve investments in GSM and to preserve traditional architecture under the network system; the continuous use of the technologies of switching and transmission of IP packets mainly to benefit mobile recharge api from low running costs. In the coming years the basic network will be optimized for data traffic in order to consider the greater part of the global traffic.
Since a large portion of data will be generated by Internet services, IP seems the best solution. Finally, since it will be possible to route voice over IP, the mobile and fixed services will share the same network resources. The level2 is divided into mobile recharge api the following sub: MAC (Medium best recharge price Access Control), RLC (Radio Link Control), PDCP (Packet Data Convergence Protocol) and BMC (Broadcast/ Protocol).
The level3 and the RLC are divided into control and user plane: the first handles the transfer of information in the network (generally of the multimedia type), while the other supervises the operations required for the connection and signalling.
