How can I calculate what signal quality I should be seeing?

GalwayWAN FAQs
The signal reported by StarOS for a particular connection can be calculated by adding up the following values (all units in dB): Free space loss (loss incurred by signal travelling from one antenna to the other - an approximation can be calculated using the formula 20 * Log10 (frequency in MHz) + 20 * Log10 (Distance in Miles) + 36.6).

Signal Quality is always showing 100%. Why is this?

FAQ
Signal Quality is a measure of the errors in the current transmission. If there are currently no errors in the received data then the Signal Quality bar will be 100%. See similar questions...

What is link quality and signal strength?

FAQs | Xwire
The signal strength value shows the RSSI received RF signal strength. In brief, it indicates the absolute signal strength. The link quality value shows the receiver SNR (signal noise ratio) or the degree of PN code correlation. It indicates the signal purity relative to noise. See similar questions...

How can transformers improve my signal quality?

JENSEN TRANSFORMERS, INC. - FREQUENTLY ANSWERED QUESTIONS
Jensen transformers improve signal quality by removing hum, buzz and interference signals of other types (such as radio frequency interference) from the audio signal. The Bessel low pass filtering effect also removes ultrasonic distortion products generated by previous amplification stages from the audio signal. These ultrasonic distortion products create additional intermodulation distortion products when amplified by succeeding stages. See similar questions...

How can I tell if what I'm seeing is a genuine signal or an artefact of the noise?

Toolkit FAQ
There is no stock answer for this question. The basic philosophy of the Toolkit is that only the simultaneous and flexible application of more than one spectral estimation method can provide truely reliable information on a given time series, when the signal-to-noise ratio is low.

What are the most common signal quality design mistakes?

USB.org - USB FAQ
Signal Quality is a mandatory test. See the signal quality test description for details. Most problems are the result of EMI "control" components like ferrite beads mounted on the signal lines. Often, these manage to destroy the integrity of the signal as well as make emissions worse. See similar questions...

Why is the radio signal quality black (zero) in my wireless client ?

www.draytek.com.au -
The ESSID of all wireless devices are the same one, but the lower case/upper case of all domain name are not the same completely. For example, one domain name is set to be 'Default', but another is set to be 'default'. That is not correct. The distance between two wireless stations (Ad Hoc mode) or between the wireless station and the WAP (Infrastructure mode) is too far. Make sure there is not any wireless interference (from other 2.

How do I know if the UHF signal that I receive is of sufficient strength and quality?

FAQ on freeview in New Zealand
A good indication is if you receive a good picture on Prime TV then there should not be a problem. If the picture is grainy or ghosting then it would be advisable to get a signal test done by a technician because the digital signal is less tolerant than the analogue signal. The digital signal does not appear grainy or ghosting if the signal is insufficient, it breaks up instead. See similar questions...

What do the signal quality values in the Association list mean?

GalwayWAN FAQs
StarOS displays information about associated clients under one of its menus. The signal for each client is reported as xxx/yyy. The meaning of xxx and yyy depends on the type of wireless cards in use in the StarOS system. If the cards are Prism or Orinoco based, xxx is the signal strength that the StarOS Access Point sees and yyy is the signal strength that the client node sees. If the cards are Atheros based, xxx is the ACK packet value and YYY is the DATA packet value. See similar questions...

Why is the link rate at 1Mb (802.11b) or 6Mb (802.11a/g) when the signal quality is high?

Wireless ISP Equipment Manufacture-Demarc Technology Groups
The Atheros radio establishes the link and then awaits traffic for the reporting. The first info is just the ACK packets from the link, to see the real signal rate traffic need to be passed thought the link. See similar questions...

How do I know that I am getting a quality signal from the cable provider?

Drop Amp & Frequently Asked Questions
Connect one of your TVs directly to the cable at the cable entry point inside your home, before any splitters or other connections. This is the very strongest signal as there is no degradation from inserted devices, and you will see the very best TV picture possible in your home. If the TV picture is not acceptable at that point, you should call your cable provider and arrange a service call. See similar questions...

Can the SIGNAL BOOSTER reduce the quality of my TV pictures?

Signal Booster Frequently Asked Questions
Yes, there may exist situations where TV picture quality is reduced but probably only where there is already enough signal level for good quality pictures. An amplifier is not recommended or needed in these situations. You could also run into a problem if there is excessive tilt across the TV channel band. All this means is that the lower channels are at or above the level for good pictures and the higher channels are below the level for good pictures. See similar questions...

Q : Can different type of cables change the signal quality (digital transfers)?

Soundcard FAQ and Sound Card Support - Auzentech, Inc. Sound...
A :No. If the connection works (and you get a fine audible signal), the quality is always the same. If you use a cable that can't be used for digital signals, you will get loud noise or no signal at all. A : AC-3 is an encoded signal (also known as"'Dolby Digital" and "5.1") that is created with special ultra high end equipment (usually in professional audio/video/TV studios) and then saved in digital data files - for example on a DVD.
