What is SCFT in telecom?

What is SCFT in telecom?

Single site verification (SSV) or Single Cell Function Test (SCFT) SSV drive test or SCFT drive test is all about performing 5G/4G/3G drive test analysis on a particular site (Example newly installed cell tower) and this is usually performed by drive testing or by walk testing around the site.

What is PCI in drive test?

PCI : Physical Cell Identity.

What is RF walk test?

RF TESTING & COVERAGE ANALYSIS Drive tests and walk tests assesses the Quality of Experience of 3G, 4G, and 5G mobile networks in a specific area by measuring throughput, network coverage and bandwidth which is of paramount importance to ensure high user quality experience is achieved on the network.

What is GSM drive test?

It is a technique used to check perfermance of network ,cells and quality of it . What are types of GSM DT? 1-Single level DT. In this type we test on a small site unit called in telecom field “end Point site ” or ” end of chain site”.

What is LTE drive test?

LTE drive tests consist of two basic types: UE or user equipment based, and benchmark testing. UE tests consist of hooking up multiple, live end-user devices such as smartphones and tablets in order for a carrier to get a good look at how devices perform on its networks.

What is drive test in Telecom PDF?

Drive testing is method of measuring and assessing the QoS of mobile network. Different sites of recent technology 2G, 3G, HSPA, WCDMA, Long Term Evolution (LTE), WiMAX are analysed by drive testing with TEMS Investigation tools.

What is Walk test in telecom?

A walk test is a tedious and time consuming task for mobile network operators, typically required to verify signal levels and quality of service provided by a newly deployed cell site. The resources spent in such tests can be reduced with the use of accurate planning and designing tools.

What are drive test parameters?

Among the major LTE drive test parameters are: RSSI: Received Signal Strength Indicator, or the strength of the reference signal. SINR: Signal-to-Noise Ratio, which compares the strength of the signal to background noise. RSRP: Reference Signal Received Power, the power of the reference signal.

What is RF sensitivity?

Editorial Team – everything RF Receiver sensitivity is a measure of the minimum signal strength that a receiver can detect. It tells us the weakest signal that a receiver will be able to identify and process. Receiver sensitivity is expressed in dBm.

What is SNR value?

SNR (Signal-to-Noise Ratio) is a ratio based value that evaluates your signal based on the noise being seen. SNR is comprised of 2 values and is measured as a positive value between 0db and 120db and the closer it is to 120db the better: signal value and noise value typically these are expressed in decibels (db).

What is SNR in RF?

SNR (Signal to Noise Radio) is actrually not a ratio but a decibel (dB) value measures the difference between the signal strength and the background noise. For instance, the signal strength is -56 dBm, noise is -86 dBm, the SNR is 30dB. SNR is also an vital factor to be considered during deployment.

What is dBm in sensitivity?

When the power is expressed in dBm the larger the absolute value of the negative number, the better the receive sensitivity. For example, a receiver sensitivity of −98 dBm is better than a receive sensitivity of −95 dBm by 3 dB, or a factor of two.

What is SNR in dB?

Signal-to-noise ratio (SNR or S/N) is a measure used in science and engineering that compares the level of a desired signal to the level of background noise. SNR is defined as the ratio of signal power to the noise power, often expressed in decibels.

What is dBm noise?

Noise (dBm) in wireless communications is a combination of all unwanted interfering signal sources, such as crosstalk, radio frequency interference, distortion, etc. This value is measured in decibels from zero to -120. The closer this value is to -120, the better, because that means there is little to no interference.

What is RSSI and SNR?

RSSI and SNR are mathematically related, in that [SNR = RSSI – RF background noise]. The reason we choose SNR is that the same range is used by the radio chipset to measure both the signal and the noise. So long as the two values, signal and noise, are measured using the same chipset, then SNR is a reliable indicator.

How SNR is calculated?

To calculate the signal-to-noise ratio, you need the level of both the signal and the noise. Then: If you have the signals in decibels (dB), subtract noise from the signal. If your calculations are in watts, use the power signal-to-noise ratio formula SNR = 20 × log(signal / noise) .
