The following list, which is not exhaustive, illustrates the standards supported in the PLA-4xx.

Table 10   Firmware Specifications 

Powerline Functionality

The HomePlug AV standard specifies how network devices 

communicate using standard electrical wiring. 
It supports a data transfer rate of up to 200Mbps. 
Data is encrypted using 128-bit AES (Advanced Encryption Standard). 
HomePlug AV compatible devices co-exist with HomePlug 1.0 devices 

but do not detect each other.
The range of a HomePlug AV network is 300 meters/984 feet in optimal 

conditions.
HomePlug AV is compatible with all OSs.
The maximum number of powerline devices on a single network is 16.
Support for 64 devices communicating on a single network is planned for 

future firmware release.
