Understanding GSM

GSM Standards

The Global System for Mobile communication (GSM) digital communications standard deﬁnes a voice and data over-air interface between a mobile radio and the system infrastructure. This standard was designed as the basis for a radio communications system. A base station control center (BSC) is linked to multiple base transceiver station (BTS) sites which provide the required coverage.

GSM 900, DCS 1800, and PCS 1900 are GSM-deﬁned frequency bands. The term GSM 900 is used for any GSM system operating in the 900 MHz band, which includes P-GSM, E-GSM, and R-GSM. Primary (or standard) GSM 900 band (P-GSM) is the original GSM band. Extended GSM 900 band (E-GSM) includesall theP-GSM band plus an additional 50 channels. Railway GSM 900 band (R-GSM) includes all the E-GSM band plus additional channels. DCS 1800 is an adaptation of GSM 900, created to allow for smaller cell sizes for higher system capacity. PCS 1900 is intended to be identical to DCS 1800 except for frequency allocation and power levels. The term GSM 1800 is sometimes used for DCS 1800, and the term GSM 1900 is sometimes used for PCS 1900. For speciﬁcs on the bands, refer to Table 1-1.

The GSM digital communications standard employs an 8:1 Time Division Multiple Access (TDMA) allowing eight channels to use one carrier frequency simultaneously.The 270.833 kbits/second raw bit rate is modulated on the RF carrier using Gaussian Minimum Shift Keying (GMSK).

The standard includes multiple trafﬁc channels, a control channel, and a cell broadcast channel. The GSM speciﬁcation deﬁnes a channel spacing of 200 kHz.

Understanding GSM

GSM Standards

The GSM framing structure is based on a hierarchical system consisting of timeslots, TDMA frames, multiframes, superframes, and hyperframes. One timeslot consists of 156.25 (157) bit periods including tail, training sequence, encryption, guard time, and data bits. Eight of these timeslots make up one TDMA frame. Either 26 or 51 TDMA frames make up one multiframe. Frames 13 and 26 in the 26 frame multiframe are dedicated to control channel signaling.

These principles of the GSM systems lead to the need for the fundamental transmitter measurements such as:

• Power vs Time - which veriﬁes that the transmitter output power has the correct amplitude, shape, and timing for the TDMA sequence.

• Phase and Frequency Error - which veriﬁes the accuracy of the transmitters 0.3 GMSK modulation process.

• Output RF Spectrum - which veriﬁes that the RF carrier is contained within the designated 200 kHz channel.

Mobile Stations And Base Transceiver Stations

The cellular system includes the following:

• base transceiver stations, referred to as BTS (frequency ranges dependent on the standard; refer to Table 1-1)

• mobile stations, referred to as MS (frequency ranges dependent on the standard; refer to Table 1-1)

Uplink And Downlink

Uplink is deﬁned as the path from the mobile station to the base transceiver station. Downlink is the path from the base transceiver station to the mobile station.

What Is An ARFCN?

An ARFCN is the Absolute Radio Frequency Channel Number used in the GSM system. Each RF channel is shared by up to eight mobile stations using Time Division Multiple Access (TDMA). The ARFCN is an integer (in a range dependent on the chosen standard, refer to

Table 1-1) which designates the carrier frequency.

1-4 Chapter1

Understanding GSM

GSM Standards

What Is A Timeslot?

GSM utilizes Time Division Multiple Access (TDMA) with eight time slots per RF channel which allows eight users to use a single carrier frequency simultaneously. Users avoid one another by transmitting in series. The eight users can transmit once every 4.62 ms for 1 timeslot which is 577 µs long.The eight user timeslots are numbered from 0 to 7.

Typically, each 577 µs timeslot has a length of 156.25 bit periods, which consists of 148 data bits and 8.25 guard bits. The 4.62 ms required to cycle through eight timeslots is called a frame. In a TDMA system, the shape of each transmitted burst must be controlled carefully to avoid over-lapping bursts in time.

industry. The software performs to the standard/date shown under

Mode Setup, Radio.

When you select the standard format for use, the instrument automatically makes measurements using the measurement methods and limits deﬁned in the standards. Detailed measurement results are displayed allowing you to analyze GSM system performance.

Measurement parameters may be altered for specialized analysis. This is done within narrow limits because the standards specify the test methods and settings.

For infrastructure testing, the instrument tests base station transmitters and receivers in a non-interfering manner by using a coupler or power splitter.

Preparing To Make Measurements

Making A Measurement

GSM measurements are intended to be used as “one button” measurements. This means that the appropriate measurement can be selected and run by a single key press once the instrument has been connected to the equipment to be tested. The measurement is made automatically using default parameters deﬁned by the selected standard and the tuning plan.

Even though the measurements are designed as one-button measurements, you may change the default settings using various setup keys. However, changing the default settings may produce measurement results that are outside of the parameters of the selected standard and tuning plan requirements.

Most measurements can be performed using the simple four-step procedure outlined in the table below. Most measurements are performed using only the primary keys listed in conjunction with a minimum of setup keys. Measurement setup keys ( used for non-standards compliant testing.

On Sets measurement averaging on. Off Sets measurement averaging off.

Default values are 10 and On, and range values are 1 to 1000.

Avg Mode Used to select the type of termination control used for the averaging

function. This determines the averaging action after the speciﬁed number of data acquisitions (average count) is reached.

Exponential After the average count is reached, each successive

data acquisition is exponentially weighted and combined with the existing average.

Cable Fault Location

Max Range Used to deﬁne the range over which faults will be measured. The

smaller the value of this ﬁeldthe more closely faults can be viewed. The value should therefore be set as close as possible to the length of the test apparatus.

The default value is 20m.

Trace Points The number of trace points used in the measurement. Changing the

number of trace points affects the minimum and maximum measurable distances. As a general rule, the longer the cable, the more trace points you should use. It is possible to select up to 8192 trace points but due to the computationally intensive FFT, the higher the value, the slower the measurement becomes. To ensure the fastest possible speed, use a value that is a power of 2—for example 512, 1024 and so on.

Window Used to select the FFT windowing function to be used. The cable fault

measurement uses an FFT to convert the analyzer frequency trace into a distance trace. To get the best possible results from the FFT, it is important to apply the most suitable windowing function to the frequency trace before performing the FFT. Possible values are Rectangular, Flat Top, Gaussian, and Hanning. The default value is Flat Top. The following table describes these values.
