Product Overview
Extollo’s LANSocket 1500 Powerline adapters are based on Broadcom’s 60500 multiPHY SoC.
Broadcom’s 60500 SoC is compliant to HomePlug’s AV2 specification. Extollo’s 1500 series of
Powerline adapters can use all three electrical wires that are present in a home to provide
application speeds of up to 500 Mbps using MIMO with beam-forming technology. This technology
will also significantly increase the signal coverage in the home, enabling HD and 4K content
distribution to every electrical socket.
The LANSocket 1500 has an electrical pass-through interface. The pass-through socket design
has integrated filters that suppress electrical noise produced from the attached electronics. These
filters prevent noise from accessing the Powerline network.
HomePlug AV and AV2 Network Overview
When HomePlug Powerline adapters are plugged into the electrical power lines they create an
AV Logical Network (AVLN) which consists of two or more HomePlug AV or AV2 adapters which
all share a common Network Membership Key (NMK). The NMK provides exclusive access to an
AVLN so that the member stations can communicate in a private and secure environment.
When a HomePlug AV or AV2 Powerline adapter is powered on, it listens to the medium. If it
hears an existing AVLN, it will attempt to join it. If it does not hear an existing AVLN, it will form
its own network. Eventually, another HomePlug AV or AV2 Powerline adapter will be powered up
and the two will associate and form an AVLN. (This is a highly simplified description; in reality,
the HomePlug AV specification provides for various cases of encountering more than a single
AVLN).
Admission control procedures ensure that only permitted devices are allowed to join the AVLN.
All data traffic and nearly all control traffic within the AVLN are secured by 128-bit AES encryption,
providing a high level of security. This encryption uses the Network Encryption Key (NEK) and
may be automatically and dynamically changed.
In order to join an AVLN, a HomePlug AV or AV2 Powerline adapter must obtain an NMK. If it
already possesses a NMK matching the existing AVLN, it may join the network immediately;
otherwise is must be provided with the NMK.
The process for a HomePlug AV or AV2 powerline adapter to obtain an NMK and join an existing
private
AVLN is called “
Pairing
”. Please see the “Creating a Private Powerline Network”
procedure within this product guide for a complete description of the process.
For further technical information on HomePlug Powerline networking, please see the AV and AV2
white papers.
