  3. GSM TRACKING

  4. What is GSM? Global System for Mobile (GSM) is a second generation cellular standard developed to cater voice services and data delivery using digital modulation.

  5. GSM Intercept We are delighted to announce the imminent release of CTS MLS (Mobile Location System). Accurate tracking, geo fencing, data base collection of target handsets tactically and strategically. Anywhere in the world at any time. Accuracy down to sector level with final sub 10m accuracy in city centers. Both fully passive and hybrid active systems for the intercept of GSM cellular communications. For any frequency across 850/900/1800/1900Mhz and from 4 channels up to vehicle installed 8700 channel systems. 2G GSM, UMTS and CDMA Protocols are all covered by the range of CTS systems.

  6. Characteristics of GSM Fully digital system using 9000 1SOO MHz frequency band. User terminal authentication for fraud control. Encryption of speech and data transmission over the radio path. Full international roaming capability. Low speed data services. Compatibility with ISDN. Support of Short Message Service (SMS).

  7. Features Provided by GSM Calling Line ID - Incoming telephone number displayed Alternative Line Service -one for personal calls -one for business calls Closed User group -call by dialing last for numbers. Advice for Charge -tally of actual costs of phone calls. Fax & Data -virtual office/professional office Roaming -services and features can follow customers from market to market.

  8. Advantages of GSM Technology Crisper, cleaner quieter calls. Security against fraud and eavesdropping. International Roaming capability in over 100 countries. Efficient use of spectrum. A wide variety of handsets and accessories. Ease of use with over the air activation, and all account information is held in a smart card which can be moved from handset to handset. Advanced features such as Short Messaging and caller ID.

  9. Disadvantages of GSM Incase of GSM, SIM cards, individual authentication keys of the users are stored in the authentication centers. Any person with the rights and qualifications to access to authentication center can manipulate these to impersonate that mobile user. Security algorithms used in GSM e.g. A3, A5, and A8 are all undisclosed algorithms. But researchers have proved that these algorithms cannot guarantee 100% security. Privacy of a call and mystery of a subscriber are only assured on the air interface among the mobile station and the base station subsystem leading to likelihood of eavesdropping of voice data.
