Hi -<br>
A question about network capacity:<br>
<br>
I'm planning to put a front end by the TV, and a back end in a
different part of the house. The primary purpose for this MythTV setup
is HDTV viewing.<br>
<br>
Some early HDTV recordings are about 2.4 GB for 30 minutes.<br>
<br>
This works out to 2.4 * 10^9 * 8 bits/B / 30 min / 60 sec/min= 10.7 Mbps</blockquote><div><br>
About 1.37 MB/sec. You can get this from 802.11g, but it's right at the
limit of the standard 54 MBps (and only if you don't use the network in
mixed mode, if you add 802.11b clients the throughput will drop).
However, this is well within the limits for the "fast" 11g, i.e.
proprietary extensions which typically double the speed of the network
(you've probably seen 108 Mbps devices advertised, that's them). The
catch is, they are usually 108 Mbps to each other, and 54 Mbps to
another brand, if you're lucky. <br>
<br>
I have a network of several Viewsonic WAP/Bridge devices (<span class="small">WAPBR-100,
CompUsa sells them on-line if you can't find them) and I get 2.4 MB/sec
transfer rate to and from my Myth box. These are ethernet to wireless
bridges, not wireless adapters, which is the best since you don't have
to mess with wireless drivers - you just take all your bridges to one
place, connect them to a PC one by one, configure them all, one as a
WAP and the rest as bridges, and then connect them to any
ethernet-enabled device, and with no changes to the device you're now
connected to wireless.<br>

For streaming from the backend to the frontend (aka accessing via NFS?)
it appears it will exceed Ethernet speed and require fast ethernet. I
don't have cable run, so my question is, for a strong signal, is it
reasonable to expect a quality stream over 54 Mbps wireless-g or is
running CAT5/6 a better bet?<br>
<br>
Thanks!<br>
