Symmetric connections such as Symmetric Digital Subscriber Line (SDSL) and T1, however, offer identical upstream and downstream rates. If a node A on the Internet is closer (fewer hops away) to the Internet backbone than a node B, then A is said to be upstream of B or conversely, B is downstream of A. Related to this is the idea of upstream ...
Dec. 13—Spectrum has announced that it has launched gigabit upstream speeds for Spectrum Internet Gig customers across Rochester, Austin, Albert Lea and the surrounding Spectrum areas, matching ...
A high-split increases the upstream frequency range to 5–204 MHz, supporting a total shared upstream capacity of ~1.5 Gbit/s (assuming 4 SC-QAM + OFDMA channels) for the service group. [ 26 ] DOCSIS 4.0 in both full-duplex (FDX) and extended spectrum DOCSIS (ESD) configurations will support upstream speeds surpassing 5 Gbit/s.
More upstream bandwidth; RFoG's improved noise characteristics allow for the use of the full 5–42 MHz return-path spectrum. Additionally, higher-performance RFoG systems not only support DOCSIS 3.0 with bonding, but also enable 64 quadrature amplitude modulation (QAM) upstream transmission in a DOCSIS 3.0 bonded channel, dramatically ...

This spectrum overlaps the FM broadcast band between 87.5 and 108 MHz, as well as various military and government radio services. To limit interference to those radio services, the ITU-T G.9700 recommendation, also called G.fast-psd, specifies a set of tools to shape the power spectral density of the transmit signal; [ 9 ] G.9701, codenamed G ...
If you're using broadband (cable) internet and you can't connect, try the following troubleshooting steps in the order listed until you get up and running again. 1. Check if you can visit other sites with a different browser - If you can go to another site, the problem may be associated the browser you're using.
Bandwidth test software is used to determine the maximum bandwidth of a network or internet connection. It is typically undertaken by attempting to download or upload the maximum amount of data in a certain period of time, or a certain amount of data in the minimum amount of time.
