GSM antenna technical characteristics
Spectral efficiency. As a result of the use of efficient modulator, channel coding, interleaving, equalization and speech coding technology, the system has a high spectral efficiency. Capacity. As the transmission bandwidth of each channel increases, so that the same frequency reuse ratio is reduced to 9dB, so the GSM system with the frequency reuse mode can be reduced to 4/12 or 3/9 or even smaller; plus half rate voice coding Of the introduction and automatic traffic allocation to reduce the number of handoffs, the GSM system capacity efficiency than the TACS system 3 to 5 times higher. 3. Voice quality. In view of the characteristics of digital transmission technology and the definition of air interface and voice coding in the GSM specification, above the threshold, the voice quality always reaches the same level regardless of the quality of wireless transmission. 4. Open interface. GSM standard provides an open interface, not limited to the air interface, and the newspaper network directly and the network between the device entities, such as A interface and Abis interface. 5. Security. Through the use of authentication, encryption and TMSI number, to achieve the purpose of security. Authentication is used to verify the user's access rights. Encryption is used for air interface, which is determined by the SIM card and the key of the network AUC. TMSI is a temporary identification number assigned to the user by the service network to prevent someone from tracking and leaking their geographical location. 6. Interconnection with ISDN, PSTN, etc. Interconnection with other networks usually takes advantage of existing interfaces such as ISUP or TUP. 7. Roaming based on SIM card. Roaming is an important feature of mobile communications, it marks the user can automatically enter a network from another network. GSM antenna system can provide global roaming, of course, also need some of the agreements between network operators, such as billing.
