Study Notes
Cellular Network Generations
- 1G: First generation, analog technology focused on voice-only communication; now nearly extinct.
- 2G: Digital systems initially designed for voice, later evolved (2.5G) to support both voice and data services.
- 3G: Advanced systems emphasizing higher data rates and integrated voice and data capabilities.
Cellular Network Structure
- Cellular networks consist of geographic areas called cells, each served by a base transceiver station (BTS).
- Coverage area of a cell influenced by factors like BTS power, user device power, physical obstructions, and antenna height.
Communication Techniques
- FDMA (Frequency Division Multiple Access): Allocates separate frequency bands for different calls.
- TDM (Time Division Multiplexing): Divides time into frames and slots for calls, assigning specific slots to each call.
- Combined FDM/TDM: Allows multiple simultaneous calls by partitioning both frequency and time.
Cellular Network Components
- Mobile Switching Center (MSC): Central unit for user authorization, call setup, and handoff; serves up to 200K subscribers when linked with several BSCs.
- Base Station Controller (BSC): Manages multiple BTS, allocates radio channels, and performs user paging and handoff within a GSM base station system.
3G Cellular Architecture
- 3G systems connect radio access networks to the public Internet while retaining the existing GSM voice network structure.
- SGSN (Serving GPRS Support Node): Manages data delivery between mobile nodes and radio access networks, also interacting with MSC for handovers and authorization.
- GGSN (Gateway GPRS Support Node): Serves as a gateway connecting SGSNs to the Internet, managing data from mobile nodes before it enters the wider network.
Key Insights on 3G Networks
- New cellular data networks operate in parallel with existing voice networks, ensuring core voice functionalities remain unchanged.
- Radio Network Controllers (RNC) oversee several BTSs, akin to 2G systems but enhanced for data operations.
Technologies and Standards
- GSM: The standard for 2G cellular systems employing combined FDM/TDM for air interface.
- WCDMA (Wideband Code Division Multiple Access) and HSPA (High-Speed Packet Access): Key radio interfaces in 3G technology.
Terminology
- BTS: Base Transceiver Station, the node within a cell.
- BSC: Base Station Controller, manages BTS resources.
- MSC: Mobile Switching Center, central management unit for calls.
- SGSN & GGSN: Nodes responsible for maintaining and forwarding data between the cellular network and the Internet.
