Bnc Jack HomePNA Advantages and DisadvantagesΒ Β by Daly
As a network technology for home LANs, HomePNA 2.0 or 3.x offers some attractive
features, particularly for installations in homes that are already extensively wired for telephone service.
Consider the following:
The system can be installed one unit at a time wherever a telephone line connection
is available. The cost of individual transmission units is low.
A large variety of networking devices are available from many manufacturers, all compatible with one another and all operating on the same HomePNA standard.
HomePNA can accommodate both PCs and Macs on the network.
The network functions as a peer-to-peer system that requires no hubs or routers.
All data is sent to all nodes. Each node reads only what is addressed to it.
The HomePNA standard transmits data at frequencies that do not interfere with
analog voice traffic, so the telephone lines can also be used for voice transmission
while the network is operating.
The HomePNA 2.0 and 3.x standards are fast enough that they can meet almost all home network requirements including video transmission.
As many as 25 devices can be networked using HomePNA, and the HomePNA system can also be connected as a segment to an Ethernet LAN.
The limitations of a HomePNA system mostly derive from limitations of the telephone wire system over which it operates:
Each device must connect to the network through a telephone jack (or a BNC connector for HPNA 3.1 coaxial cable). The network is limited in scope by the number of available connection points. New jacks can be added, but wiring these is as dif? cult as wiring new jacks for an Ethernet.
The system has some physical size limits. The maximum length of wiring between all devices on the network is 200 meters or about 650 feet (some HomePNA 3.1 systems can be "power boosted" to achieve longer distances up to 1,500 meters), and the area encompassed by the network cannot be more than 10,000 square feet, which is slightly less than the area of a quarteracre
lot.
HomePNA will not work in some large homes that have old and extended telephone
wiring.
Once installed, HomePNA systems sometimes increase noise levels or cause distortion
on the voice side of the telephone lines. This problem can often be
