What is good ADSL line attenuation?
Optimal values should be between 5 and 30 dB (excellent or good line). An attenuation value of 45 dB or higher means that the line is not suitable for ADSL.
What speed should my ADSL be?
In general, the speed you can obtain from each provider should be the same at your location….What speed should I get on ADSL?
Connection Type | Max Mbps | Minimum Mbps |
---|---|---|
ADSL | 8 Mbps/1 Mbps | 1.5 Mbps/0.8 Mbps |
ADSL2+ | 24 Mbps/1 Mbps | 1.5 Mbps/0.8 Mbps |
ADSL2+ Annex M | 24 Mbps/2.5 Mbps | 1.5 Mbps/0.8 Mbps |
What’s the fastest ADSL speed?
24.0 Mbit/s.
As wikipedia says the max speed of ADSL is 24.0 Mbit/s.
What is attenuation on ADSL line?
Attenuation is the weakening or minimizing of power in terms of intensity. It is also the name of a common problem experienced by DSL users. Attenuation of the line occurs when noise and interference enters the DSL transmission and weakens the strength of the connection, slowing the speed of your broadband connection.
How can I improve my ADSL line quality?
Luckily, there are some things you can do to improve the SNR margin:
- Buy a router that is good enough to manage low SNR margin figures.
- Install a good quality ADSL filter to your router and to each phone device installed on the same line.
- Try to change the ADSL provider, as some providers are less crowded than others.
What speed ADSL2+ should I get?
ADSL2 can achieve downstream data rates of up to 12 Mbps speeds at its source while ADSL2 can achieve up to 24 Mbps. ADSL2/2+ are best suited for longer loop lengths. ADSL2 can reach distances of up to 5,000 meters while ADSL2+ can achieve up to approximately 6,000 meters.
How do I lower ADSL attenuation?
What is a good attenuation rate?
In short, the lower this number is, the better: 20dB and below is outstanding. 20dB – 30dB is excellent. 30dB – 40dB is very good.
How do I reduce attenuation on ADSL line?
What is the standard DSL line attenuation range?
The standard signal attenuation spread for a given speed is somewhere in the region of 15-20dB for ADSL2/2+ speeds and 25-30dB for ADSL1 speeds. The following is a “guesstimate” of the line attenuation and maximum attainable speed based on distance:
How does attenuation affect the speed of broadband?
Broadband signals from the exchange suffer attenuation as they travels along the cable from the exchange to your broadband modem, reducing the speeds that can be delivered.
Which is better ADSL or ADSL2 + for distance?
ADSL2+ provides most benefit for premises close to the exchange. For distances between 3 km and 3.5 km, where ADSL speeds have fallen well below 10Mbps, ADSL2+ and ADSL2 still provide worthwhile increases in connection speeds. There is very little difference in performance at distances above 4 km.
What are the parameters of an ADSL connection?
The main technical characteristics of the established ADSL connection are presented in the parameters ‘Standard’, ‘Speed’, ‘Noise margin’, ‘Signal power level’ and ‘Signal attenuation’. Below are descriptions of the specified parameters and characteristics of the physical communication channel (leased line) of the ADSL technology.
