2G GSM GPRS Network Lab Simulation
2G GSM GPRS Network Lab Simulation Overview GL offers an End-to-End 2G and 2.5G GSM GPRS Wireless Network Simulation Test Suite with all components such as Base Station, RF channel, GSM core network elements such as BSC, MSC, HLR, and GPRS core elements such as SGSN, and GGSN to support mobile call and traffic emulation. The lab system can operate with real mobiles, or simulator user profiles. By mimicking real-world customer behavior in lab environments, our solutions allow mobile operators and equipment manufacturers to verify their wireless networks before deployment. In other words, one can setup a virtual real-time network simulating all the network elements using “MAPS 2G Wireless Lab Suite”. The test suite supports simulation ofGSM Abis, A, C/D/E, Gb, and GnGp interfaces. In addition, with MAPS™ HD RTP appliance you can generate high call intensity (hundreds of calls/sec) and high volume Voice and SMS calls (thousands of simultaneous calls/platform). MAPS™ supports automated stress/load testing capabilities through Load Generation and Bulk Call Simulation features. To perform Bulk Call Generation, several UE/Subscriber configuration files are required. The UE/Subscriber configuration files can becreated using regular Profile Editors (XML Based), using CSV based profiles, or using Auto Generation feature for simulating inter-networking calls, roaming calls, data sessions, and bulk GTP traffic generation. Complete 2G GSM lab simulation can be realized using GL’s Remote MAPS™ feature, a client server module, designed for multi-node multi-interface simulation from a single GUI. The application has the ability to remotely control multiple MAPS™ Servers running on different PCs from a single remote client application. -

The Spectrum Policy Dictionary
The GSMA spectrum primer series The spectrum policy dictionary 1 2 The spectrum policy dictionary These handbooks provide a general introduction to mobile spectrum, how it is managed and the challenge posed by rapidly growing data usage. They have been designed for readers who don’t have a technical background in the subject. While this is only a very brief introduction to the subject, these handbooks should hopefully provide a useful overview. 4 The titles in this series are: Introducing radio spectrum Introducing spectrum management Managing spectrum for growing data The spectrum policy dictionary 5 1G The first generation of ‘cellular’ mobile phone systems used in the late 1970s until the early 1990s. These analogue-based systems were replaced by 2G digital mobile systems - most notably GSM. Examples include AMPS (Advanced Mobile Phone System), NMTS (Nordic Telecommunication System) and TACS (Total Access Communications). 2G The second generation of ‘cellular’ mobile phone systems which appeared in the 1990s were the first to employ digital coding. The vast majority of 2G mobile networks around the world use GSM technology. However, there are other 2G systems including D-AMPs, PDC, iDEN and most notably cdmaOne which continues to be used by some operators around the world. 2.5G see GPRS 2.75G see EDGE 3G The third generation of ‘cellular’ mobile phone systems were the first to be designed from the outset to support high speed data services as well as voice. The most dominant system used is WCDMA which was deployed by the operators which previously used GSM. However, other systems are used including CDMA2000 (largely by operators that previously used cdmaOne) and the Chinese system TD-SCDMA. -
