What is RTWP in telecom?
What is RTWP in telecom?
What does RTWP stand for? Represents a measure of UMTS technology: the total level of noise within the UMTS frequency band of any cell. RTWP is related to uplink interference, and its monitoring helps control the call drops – mainly CS.
What does RTWP mean?
Total Wideband Power
One of the major issues facing a Radio Access Network (RAN) mobile operator is coping with the uplink interference in their RAN, such as the Receive Total Wideband Power (RTWP) in the Universal Mobile Telecommunications System (UMTS) band. A frequently occurring issue in such networks is the RTWP alarm.
What causes RSSI?
UL RSSI that is too high will contribute to poor network quality. Interference caused by the high noise floor can lead to frequent dropped calls, call setup failure, and poor voice quality. Improper installation of a service antenna caused high RSSI problems, affecting LTE services.
Is RSSI 72 good?
The RSSI value is quite important here – it stands for Received Signal Strength Indicator, and any values below -60 could indicate an issue. Of course, below -60 means a value between -60 and -100 – a value closer to 0 is actually good.
Is RSSI 56 good?
Is RSSI 55 good? Yes, an RSSI value of 55 is generally considered to be good enough for most users and online activities. If measured in negative numbers (with 0 meaning the best signal possible and -100 the worst), then the relative quality of a received signal on a device is slightly worse, but still acceptable.
Is RSSI 69 good?
Is RSSI 33 good?
RSSI Reading Meaning -66 to -90 is critical and will likely cause a loss of functionality or be unable to maintain a usable connection the wifi altogether. -65 to -41 is sufficient. Possible video issues if constantly at -60. -40 or better is virtually no interference and a very strong signal.
Is RSSI 49 good?
The higher the RSSI value, the stronger the signal. When measured in negative numbers, the number that is closer to zero usually means better signal. As an example -50 is a pretty good signal, -75 – is fairly reasonable, and -100 is no signal at all.
What is received total wide band power RTWP?
Answer Wiki. RTWP : Received total Wide band Power , RTWP Is the level of noise withing the frequency band of any cell or you can say the uplink interference. Now the uplink interference is due to a number of reasons like number of users , condition of radio connection type etc. But the most common reason is the number of users in that cell.
Why is the range of RTWP so high?
But the most common reason is the number of users in that cell. The range of RTWP is shown below. The higher the value of RTWP , the degraded the quality of services of that cell. Physical Verification like cables, jumpers & connections loose connection could generate interference.
Why does uplink interference occur in RTwP mode?
Now the uplink interference is due to a number of reasons like number of users , condition of radio connection type etc. But the most common reason is the number of users in that cell. The range of RTWP is shown below. The higher the value of RTWP , the degraded the quality of services of that cell.
How to know if RTWP is a hardware problem?
If have alarm or high VSWR (more then 11), first escalate to BSS team, then assistant them to check whether it is hardware problem or interference. Usually the value of these two parameters should be 0, if it is not 0, fallback to 0 to check whether RTWP can restore normal. This configuration will affect the RX gain.
