When this value gets close to -100, performance will drop drastically RSRQ counts the signal in the air relative to the RSRP for the currently selected channel. Very low. An RSRP of -95dBm would be a strong signal whereas -115dBm would be very weak. Free space path loss is a weakening of the RF signal due to a broadening of the wave front. Now, when the signal approaches -120 that's when problems occur. With RSRP, a signal of -100 dBm is a decent signal where, with RSSI, it would have been unreliable for data transfers. However, due to mobility it moves to connect to the macrocell where the SINR changes. RSSI – Received Signal Strength Indicator. -90dBm is excellent, -120dBm is poor or no signal RSRQ – For LTE frequency. This is the truest measurement of the cell signal you can actually use. RSRP is a measure of signal strength for LTE: -44dBm to -140dBm. RSRP (Reference Signal Received Power): RSRP measures the power level of the received reference signal in a particular cell. Namely, the reading of RSRP represents the signal strength of your iPhone. It is the power of the LTE Reference Signals spread over the full bandwidth and narrowband. Thanks again RSRQ-7. e. Another option to boost speed is to see whether your service provider has LTE-Advanced service in your region. RSRP Reference Signal Received Power RTS Real-Time Strategy Game RTT Round-Trip Time SD Standard Definition SINR Signal to Interference plus Noise Ratio SLA Service Level Agreement SLG Simulated Life Game SPG Sports Game STG Shooting Game TCP Transmission Control Protocol TDD Time Division Duplex. You want something that supports modern LTE Releases (listed as Category 6/7/8 etc). If no indicator is lit, then the signal strength is insufficient to connect to the network. RSSI is a measure of signal strength for GSM (2G/3G): -50dBm to -113dBm. RSRQ is Reference Signal Recieved Quality. But that does not actually translate to stronger signal to the end user. g. RSRP at -102. RSRP; RSRP Signal strength Description >= -80 dBm: Excellent: Strong signal with maximum data speeds-80 dBm to -90 dBm: Good: Strong signal with good data speeds-90 dBm to -100 dBm: Fair to poor: Reliable data speeds may be attained, but marginal data with drop-outs is possible. The RSRP value is measured in dBm (dBm). RSRP does a better job of measuring signal power from a specific sector while potentially excluding noise and interference from other sectors. Good-80 dBm… -90 dBm. For RSRQ, -10 dB is an excellent signal, whereas -20 dB is no signal. Any SINR over 10 dB is excellent, over 5 dB is considered good, while over 0 dB is acceptable. First Things First: The Site SurveyRSRQ 3GPPDefinitionReference Signal Received Quality (RSRQ) is defined as the ratio N×RSRP/(E-UTRA carrierRSSI), where N is the number of RB’s of the E-UTRA carrier RSSI measurement bandwidth. -121 to -124 is poor. That is your phone’s signal strength. 1. - RSRP: Received Signal Reference Power – the average of the power received of all radio resource elements that carry cell-specific reference signals. What causes poor signal quality? RSRP is short for Reference Signal Received Power, used when measuring 4G LTE networks. RSRP (dbm) RSRQ (dB) Excellent. . Get a New Phone/Hotspot sometimes is a good way to improve RSRP. A reliable and ubiquitous mobile communication link plays a vital role in ensuring flight safety. Our users in other countries also experienced significant drops in average 5G download speeds, between the Excellent and Weak signal strengths. Figure 1 shows that the mobile network type is LTE with a signal strength of − 98 dBm, and the ASU is 42. >= -80. M1 and NB IoT) signal strength/quality parameters: RSRP, RSRQ, RSSI, SINR and their meaning. RSRQ stands for Reference Signal Received Quality. " You want your RSRQ to be as close to 0 as possible (or above 0 is also good!) RSRP, You want the RSRP to be below -100 if possible. 6a. An RSRP of -95dBm would be a strong signal whereas -115dBm would be very weak. What Is A Good Rsrp Signal Strength; What Is A Good Rsrp Signal Strength. ETSI 3GPP TS 38. SINR = -1,8 dB. As per the definition of RSSI, It is wide band power including signal power from serving cell, co-channel neighbour cell, interference from other cell interference and noise, in similar word one can say that RSRQ define the purity. What is a good RSRP? RSRP The average power received from a single Reference signal, and Its typical range is around -44dbm (good) to -140dbm(bad). Unless you are only getting LTE in which case move the trashcan around the house until you get 5G. 9. 0 Release 15 6 ETSI TS 138 215 V15. When this value gets close to -100, performance will drop. This article explains how to interpret some of. UE Unable to Access due to Incorrect Parameter Configuration (2) Analysis: The UE should report the Status packet to the eNodeB after it receives the LTE DL AM All PDU message. RSRP=Linear Average Power of Reference Signal. The results of the parameter (SS-RSRP) observation showed that Scenario 2 (Downlink-O2O-NLOS) had the highest average SS-RSRP, namely-65. What is dbm and how does it affect your cell signal?Lower signal strength impacts the swiss 5g experience Switzerland’s regions struggled to see a good 5g signal strength on theHow to determine good cellular signal strength. That means the RSRP signal strength is the same regardless of the size of the band, and it only measures the signal from one tower. For RSRP determination the cell-specific reference signals R0 according TS 36. Reference Signal Received Power (RSRP): RSRP is the linear average of reference signal power (in Watts) measured over a specified bandwidth (in number of REs). RSRQ. The closer you are to zero the stronger your signal. The above table is based on throughput performance from different bands. How should we interpret these numbers?If you have used the LTE Link Monitor tool, the RSRP determines the visualized signal strength in the right top corner and it is plotted in the chart view. The RSRP is basically the connection signal from your router to the cell tower. I personally once achieved 363Mbps with a RSRP of -120 and a RSRQ of -5, so it was a really weak signal but it was very good quality. The ‘current’ and ‘RSSI’ numbers look like something went wrong. Built-in CW generator 300 kHz to 50 GHz. The output power used in the UE. RSSI = Received Signal Strength Indicator. It indicates the signal strength between the base station (cell tower) and the modem. One is the signal strength ( RSRP ) and other one is the signal quality ( RSRQ ), both are important here to consider your iPhone has a good. Those readings are not too good. My SINR is almost always in the negatives and my RSRQ is almost always between -28db and -32db. Supposedly rsrp0 is the primary cell tower connected to, and rsrp1 is the next closest cell tower (or one with the strongest connection anyway), each obviously has their own cellular signal. Strong signal enabling maximum data capacity. k. A cellular phone or another LTE-equipped device would display signal strength in RSRP, measured 0dBm (best signal) to -110dBm (weakest/no signal). You can think of RSRP as how strongly the signal from the cell tower is 'heard' from the device. #2. Once I get some directional antennas I can better confirm which direction the signals are coming from. 6. These signal values will be represented as a negative number. While you could measure signal strength with bars, dBm readings are much more accurate. These will show both SINR (signal clarity) and RSRP (signal strength), making it easy to test various antenna directions and locations to find the best signal. N41 can handle a lot more load than N71, so N41 is helped because of that reason. You may also want to check on your 4G LTE readings, and possibly find a better location to place your device until the tower is. A. e. Tap Cell Info. Good-7 to -10 -9 to-12: Fair to poor. RSRP RSRP Signal strength Description >= -80 dBm Excellent: Strong signal with maximum data speeds -80 dBm to -90 dBm Good: Strong signal with good data speeds -90 dBm to -100 dBm Fair to poor: Reliable data speeds may be attained, but marginal data with drop-outs is possible. Analogous to the SNR used often in wired communications systems, the SINR is defined as the power of a certain signal of interest divided by the sum of the interference power (from all the other interfering signals) and the power of some background noise. As of 3GPP 38. • SS-RSRQ stands for Secondary synchronization Signal Reference Signal Received Quality. Any RSSI value lower. RSRP is short for Reference Signal Received Power, used when measuring 4G LTE networks. XBee module's pin 6 can be configured as an RSSI pin that outputs a PWM (pulse-width modulation). My SINR is almost always in the negatives and my RSRQ is almost always between -28db and -32db. May 28, 2021 | Articles RSRP, RSRQ and SINR are three important parameters used to measure the quality of a cellular network signal in LTE (Long-Term Evolution) technology. So when they are equal, that ls 10 times the log of 1, which is 10 times zero, or zero. 133 V8. rsrp is one of the key parameters and physical layer measurement requirements that can represent wireless signal strength in LTE networks. 1 to -90 dBm: Good: Strong signal strength-90. RSSI is the power of all signals at the interface for the channel it is currently operating in. 5G NR RSRQ | SS-RSRQ, CSI-RSRQ. Tap “Status” or. The maximum level correspond to the three burning indicators. If your signal is very weak to begin with, chances are you will need both an antenna and an amplifier. Figure 8 shows the transmission power P T X, U E of the NB-IoT UE at different signal levels. RSRP – Reference Signal Received Power is an RSSI type of measurement. RSRP stands for “Reference Signal Received Power. These signal values will be represented as a negative number. (Learn more about cell signal strength and how to measure it here. Windows offers a built-in command that can show the signal strength. UE comes to know which antenna port can be used for measurement, when it decodes SIB3. What is a good RSSI value? 55. The values of RSRP (Reference Signals Received Power) and RSRQ (Reference Signal Received Quality) are used to measure the signal level and quality for LTE networks like 4G or 5G. 1 Like. 020 dB per foot in an outdoor or wide open office; doors, walls, glass, and etc. RSRP is an average power received and typically ranges from −44 dBm (good signal strength) to −140 dBm (poor signal strength) . It typically ranges from -50 dBm to -120 dBm. -104 is greater than -105)The RSRP is the received power of the reference signals, which includes both the CRS and the CSI-RS. RSRP refers to the received signal power from an eNodeB, which can directly reflect the signal strength at a specific location. IF RSRP is is good but RSRQ is bad, you have noise ! If SINR is, say 13 dB but RSRP is below -80 or RSRQ is below -10 it indicates a problem and then easiest to use SINR only. RSRP Signal strength LTE FIX'S Rating >= -80 dBm: Excellent: Premium signal strength-80. 5(bad). The CDF for RSRP is 61% for the range −80dBm (good condition), 20 % for 95dBm (fair condition), and 1 % for range −100 (poor condition) for OP1 which provide most of the area with good signal strength that provides fast data transfer as shown in Fig. The ‘RSRQ’ indicates excellent signal strength while the ‘RSRP’ suggests we have no signal at all. Reference Signal Received Power (RSRP) gives you an idea of the power of the LTE Reference Signals spread over the full bandwidth. Reference Signal Received Power (RSRP) is a cell-specific signal strength related metric that is. See the wireless icon next to the network. 1. A cellular phone or another LTE-equipped device would display signal strength in RSRP, measured 0dBm (best signal) to -110dBm (weakest/no signal). Tap LTE on iOS 11-13, or the Menu Tab on iOS 13-14. When this value gets close to -100, performance will drop. For RSRQ, -10 dB is an excellent signal, whereas -20 dB is no signal. RSSI is a negative value, and the closer to 0, the stronger the signal. The impact on MOS by different reference signal received power (RSRP), signal-to-interference noise ratio (SINR),. The signal strength of the modem can also be determined using the SIGNAL STRENGTH indicators on the top panel of the device. This is the common key performance parameters for LTE drive test parameter we have to work out for LTE drive test task. Generally n71 will have to have significant better SNR in order for it to be better than n41. What is a good RSRP in LTE? RSRP – The average power received from a single Reference signal, and Its typical range is around -44dbm (good) to -140dbm(bad). – powertec teleUnderstanding rssi, rsrp,. Kehinde_Bamiro May 1, 2018, 10:17pm 7. a. It provides an indication of the radio link quality between the device and the serving cell. But there is a price to pay -- the signal strength simply gets skewed toward larger numbers. With values lower than −8 dB, MOS suddenly. Note: Because an RSSI value is pulled from the client device’s Wi-Fi card (hence “received. If no indicator is lit, then the signal strength is insufficient to connect to the network. EUTRAN (4G. That's nearly three times less than T-Mobile, whose users experienced a slow download speed with full bars 3. HO와 Cell Reselection을 결정하기 위해 cell signal의 강도를 선택하는데 도움을 주는 지표. RSRP levels for usable signals are typically about − 70 dBm near the. RSRP RSRP Signal strength Description >= -80 dBm Excellent: Strong signal with maximum data speeds -80 dBm to -90 dBm Good: Strong signal with good data speeds -90 dBm to -100 dBm Fair to poor: Reliable data speeds may be attained, but marginal data with drop-outs is possible. According to the 4G coverage maps of O2 and Vodafone, we are located in a good signal strength area, with decent indoor coverage indicated. RSSI – Represents the entire received power including the wanted power from the serving cell as. MY RSRP IS -137. • SS-RSRQ stands for Secondary synchronization Signal Reference Signal Received Quality. These included Received Signal Strength Indicator (RSSI), Reference Signal Received Power (RSRP), and Reference Signal Received Quality (RSRQ) for the 4G network. Based on these calculated Euclidean distances, UE position can be estimated by the Nearest Neighbor (NN) algorithm or the k-Nearest Neighbor (k-NN) algorithm [ 10 ]. For RSRP levels below −102 dBm, the maximum cell-specific output power of P C M A X, c = 23 dBm was used. RSSI < -90 dBm: this signal is extremely weak, at the edge of what a receiver can receive. It is a measure of how much signal power the device loses over a given distance. Energy per chip to interference power ratio (EC/IO) is a measure of the quality/cleanliness of the signal from the tower to the modem and indicates the signal-to-noise ratio. The GSM ASU signal is represented by RSSI, which was clustered around 10 RSSI to 25 RSSI units, while the UMTS/HSPA represented by. When this value gets close to -100, performance will drop. Primary Signal B2. where N is the number of received reference signals and P n is the received power of n-th reference signal. RSRQ is the measurement of the signal strength your gateway gets from your cell tower. Next fundamental measurement is RSSI. The range in the signaling may. Reporting range -44…-140 dBm. SNR 12 dB. However, the analysis of UE logs shows the eNodeB does not receive the Status packet. If your RSRP is less than -80 dBm (e. ) Signal strength is important, but it’s only as good as the quality of the signal itself. RSRP value is measured in dBm. Thus, we will be focusing on 4G. It is measured in most of LTE chips and this is one. An RSRP of -95dBm would be a strong signal whereas -115dBm would be very weak. However, the technical aspect of having usable signal depends on two signal metrics: RSRP (signal strength) and SINR (signal quality). Generally, 4G signal. RSRP levels for usable signal typically range from about -120 dBm at the edge of LTE coverage to -75 dBm close to an LTE cell site. Fair-90dBm to -100dBm-15 to -20dB. RRC_IDLE intra-frequency, RRC_IDLE inter-frequency, RRC_CONNECTED. * RSRQ (Reference Signal Received Quality) : 단말기가 수신하는 pwr 대비 reference pwe의 비율. The dBm scale is roughly between -50 and -120dBm, with -50 being perfect signal and -120 being when you fall off the network. RSRP Values range from around -44 dbm (good) to -140 dbm (bad) anything beyond -125 is probably useless. The higher the SNR the better your signal quality will be. 3 Good SINR 13. Regarding the signal: that seems pretty good! 3-4 out of 5 should mean a quite good RSRP and 50mbps should mean that the SINR is positive. Tap “SIM Status”. Table 3 shows the RSRP ranges from excellent to poor. For the average user, field test mode is used to accurately and easily measure signal strength and signal quality. If the antenna is wanted you might need an amp. Makes a significant difference to signal: RSRP is improved by about 6dBm, RSRQ stays more consitently in low single-digits, and SINR sits solidly at +/- 20dB (whereas before it would often dip down to 10dB). M1 (LTE-M) has over 4G LTE: • CE Mode A: A maximum of UL/DL 32 Repetitions with QPSK, supported by all LPWA platforms. Positioning and Aiming MIMO Antennas Positioning and aiming MIMO antennas well is crucial to getting the best performance to your Verizon Jetpack MiFi 8800L, or indeed any other hotspot.

Firstly; feel free to correct me if my understanding is wrong- but. The greater the RSRP value, the stronger the cellular signal. RSRP is expressed in dBm (decibel milliwatts), and a higher RSRP value. It also may show you a blank dashboard. com Signal quality. RSRP is Reference signal Recieved Power. This. 6% in average download 5G speeds between Excellent signal (above -85 dBm) to Weak (-115 dBm to -105 dBm) — from 306. In my instance just a couple numbers improvement in RSRP resulted in a huge gain in speed and reliability. We exploit the 5G SS-RSRP used for signal quality measurement, to estimate the distance between two Connected Objects (COs) in move and in a dense urban area. The closer this number is to 0, the stronger the. For the range 1 to 96, ASU maps to. For example, even if all other factors were equal, VZW 10 MHz LTE bandwidth RSSI would measure 3 dB greater than would Sprint 5 MHz LTE bandwidth RSSI. #2. 20mbps!!!Key Findings. If I left the router band. RSRQ – Indicates quality of the received signal, and its range is typically -19. Likewise, if a transmitter is moved farther away, signal strength at the receiving antenna decreases. 4G LTE RSSI vs RSRP. 11. RSRQ – Indicates quality of the received signal, and its range is typically -19. 4: The reporting range of RSRP is defined from -140 dBm to – 44 dBm with 1 dB resolution For Cat M, we can Refer to the RSRP and set the signal bar as below: rsrp: -90 dBm good rsrp:-100 dBm Normal rsrp:-110 dBm little bad rsrp:-120 dBm very bad <lte_sinr> (Signal Input to Noise Ratio) Limits: 0~250(corresponds to -20 to 30. In my instance just a couple numbers improvement in RSRP resulted in a huge gain in speed and reliability. This paper presents a first study to analyze and optimize A5 parameters for jointly maximizing two key performance indicators (KPIs): Reference signal received power (RSRP) and handover success. 0 (2020-07) Foreword This Technical Specification has been produced by the 3rd Generation Partnership Project (3GPP). Open Signal is available in App Store (Mac) and Android's Play Store. Below are explanations of the LTE signal strength parameters: SINR/SNR – The signal-to-noise ratio of the given signal. For three of the four operators (AT&T, Verizon, and Sprint) the Southwestern United States was the worst. Reference Signal Received Power (RSRP) is a cell-specific signal strength related metric that is used as an input for cell resection and handover decisions. The values of RSSI and RSRP are used for the calculation. RSRQ = Reference signal received quality. RSSI, (Received Signal Strength Indicator), as well as RSRP (Reference Signal Received Power). What is a good Rsrp signal strength? Reference Signals Received Power (RSRP) and Reference Signals Received Quality (RSRQ) are indications of your signal performance. The measurements in N (Numerator) and D (Denominator) shall be made over same. The signal strength is reported by the Received Signal Strength Indicator (RSSI). Wideband N = Full bandwidth (up to 100 Resource Blocks or 20 MHz) The reference point for RSRQ measurement is the antenna connector of the UE. Here is something in addition to John Getze's explanation from the VZW site which I do not agree with the LTE signal reference as it's actually RSRP instead which means you should show a signal of -112dbm being equivalent to -92dbm as the difference in RSSI and RSRP is about 20dbm. 873dBm while the lowest average SS-RSRP was obtained by. RSRP = -97 RSRQ = -15 SINR = 5. Some users recommend optimizing for RSRQ, which is a blended metric. RSRP does a better job of measuring signal power from a specific sector while potentially excluding noise and interference from other sectors. -106 to -120 is fair. Next fundamental measurement is RSSI. Any RSSI value below -80 dB is regarded to indicate a weak signal. Your dBm is read as rsrp. Signal Strength (RSRP) Signal strength (RSRP) is measured in decibels milliwatts (dBm). 3GPP TS 38. The signal strength of the modem can also be determined using the SIGNAL STRENGTH indicators on the top panel of the device. I'm now getting around 5 - 8Mbps down and 20Mbps up.

Fair/usable signal with possibility of dropouts and slowdowns. Dial *3001#12345#* and tap the green call button. Good Signal = Bad Speed, Bad Signal = Good Speed?. In NR, SINR seems to be an important power criteria. LTE modems report the SINR, RSRQ, and RSRP. RSRP stands for Reference Signal Received Power and is a variation of RSSI measurement. The 1st Secondary Component Carrier RSRP and SCC1 RSRQ are shown in Table 5. Here are the 5G numbers. Reference Signal Received Power (RSRP) gives you an idea of the power of the LTE Reference Signals spread over the full bandwidth. The measurements campaign specifically examine the behaviour of the RSRP, RSRQ, RSSI, SINR, PCC PHY DL Throughput, and the PDCP DL Throughput. The normal range for RSRQ is -3 to -19. It is used to define signal strength in wire and cables at radio and audio frequencies. The closer this number is to 0, the stronger the. If your gateway reports the PCI physical cell identifier then you can locate the cell and better position your gateway. As illustrated in Figure 2 b the modelled RSRP of the mobile UE is. K. There's a big difference between -105 and -120. RSRP at -102. 4G LTE RSSI vs RSRP. 1-1. You can still get reception with negative values, but it’s not a great place to be. There's a guide on our website on how to get this metrics:. RSRP gives you an idea of the strength of the signal it gets from the network, but it is not clear indication of how good the signal quality is. Signal Strength: Definition:. also, i saw my upload speed briefly spike to 9. This value is reported by the cellular modem in dBm and ranges from -44 to ‑140dBm where higher magnitude values indicate more power. For VZW 10 MHz bandwidth LTE, RSSI should be approximately 23 dB greater than RSRP. These are both values that measure signal strength. It is the average value of the signal power received on. RSRP – The average power received from a. In this case, even though you have a great Signal Strength value,. a reference signal, the closer to the presentation location, the better the signal strength received, but if it is far from the location of the coverage service, the worse the signal strength received. ) display some parameters to help optimizing 2G/3G/4G connexions. Digits that are in bold type refer to best performance. If it appears RSRP0 and RSRP1 at the same time. 1 [ 1], perform cell search to detect the cells which are present, and finally make RSRP measurements in order to perform cell reselection. RSRP (Reference Signal Received Power) is the average power value of received pilot signals (Reference Signal) or received signal level from Base Station. The chart below shows the relation between the value of RSRP and signal. Loss of connection Field Test Mode for Android Users. “Network”. RSRP – The average power received from a single Reference signal, and Its typical range is around -44dbm (good) to -140dbm(bad). Excellent signal strength on the RSRP scale is anything stronger than about −85 dBm; poor signal strength is anything less than about −115 dBm: RSRQ is th Reference Signal Received Quality and it can be defined using following equation: RSRQ= (N* RSRP)/RSSI. Smaller negative numbers represent a cleaner/stronger signal. An annoying problem is there are areas with good RSRP (signal strength) but poor RSRQ (quality), and all these phones choose LTE band 2, which is either slow or unusuable. 1% of the time on average. According to the instructions, the RSRP (Reference Signal Received Power) should be between -40 to -80 dB, and anything below -120 is "very poor". The four parameters are: RSRP. Support for multiple signal measurement types. Both RSSI and RSRP values are displayed as negative numbers. From this I can use chart nodes to monitor the signals ongoing. It should be closer to 80 (mine is 71). Signal strength, which is called RSRP in 4G LTE and 5G networks, definitely matters. Just turn Wi-Fi off temporarily. RSRQ – Indicates quality of the received signal, and its range is typically -19. ”Tempered LTE-capable Airwall Gateways offer three useful metrics for measuring LTE Signal Strength. 5: Fair-102 to -111-9. RSRQ for lte connection especially EM74xx module I found following ranges in AT reference manual but there was no mention about good range. RSRQ: . You have a RSRQ of -18, which means that the signal is very low quality. Tap “About Phone”. A minimum of -20 dB SINR (of the S-Synch channel) is needed to detect RSRP/RSRQ RSRP does a good job of measuring signal power from a specific sector while excluding interference and noise from other sectors. RSRP (Reference Signal Received Power) - the average power of the received pilot signals (Reference Signal) or the level of the received signal from the Base Station. Here's a snapshot: SINR: 3db. An RSRP of -95dBm indicates a strong signal, whereas -115dBm. RSRP is the is the power of the reference signal, presumed to be a very narrowband signal. LTE Signal Interference (SINR) -1. A cellular phone or another LTE-equipped device would display signal strength in RSRP, measured 0dBm (best signal) to -110dBm (weakest/no signal). Strength rsrp rsrq twilioFrequencies cellular freq Rsrp sinr rsrq lte poyntingHow to measure raw signal. The odd thing is, when I swap out the XPOL with some 9dBi paddles, I get much better SINR: SINR: 15db. The maximum power for LTE (RSRP) at the antenna connection of user equipment is − 25 dBm. Like. Nothing is sent by the tower except the reference signals. The RSRP value is measured in dBm (dBm). SSID(i)); To get and print the RSSI (Received Signal Strength Indicator), use the WiFi. RSSI > -55dBm: this is a very strong signal. Physical Cell ID (PCI) is one of the most important cell’s. The higher the value (i. RSSI, or “Received Signal Strength Indicator,” is a measurement of how well your device can hear a signal from an access point or router.
