How to Choose power line modems

When it comes to choosing a powerline modem, there are a few things to remember. Byline networking is an affordable and straightforward way to extend a network. Still, in order for it to work well, the following features of the powerline adapter should be considered before purchase:

• Speed: When thinking about power line adapters, the network speed that can be achieved depends on the model and the powerline technology used. The adapter model chosen should support a network speed that is the same as or higher than that of the desired internet usage. Internet activities such as gaming online, streaming, or downloading will require a higher speed.
• Throughput: The throughput of an adapter depends on the internet connection and what kind of usage it will have. The number of devices that will be connected to the adapter will also determine the throughput. Throughput refers to the data transfer speed that can be achieved in a practical sense and is usually less than the maximum speed.
• WiFi Extenders: Some powerline modems have WiFi Extenders that can be used to expand a network’s area. These adapters will take in the WiFi signal and create a new WiFi network. The WiFi network can be utilized in areas where it was previously unavailable.
• Multimedia Applications: Another feature that some powerline modems have is multimedia applications. This allows users to engage in activities like streaming IPTV and gaming. Using multimedia applications on these adapters provides latency, which is important for gaming and streaming.
• Plug and Play: A feature found in most powerline modems is one that requires little configuration. These adapters are easy to install and require only to be plugged in. No technical expertise is required to install these modems.
• Homeplug AV and ITU-T G.9960: When choosing a powerline modem, it should be one that at least complies with the standards of Homeplug AV. These are international standards that give guidelines on how data can be transmitted over electric lines. The modems should also comply with ITU-T G.9960 regulations, which cover ITU-T G.9900 to ITU-T G.9999.
