Networking in Media Players
Networking speed in Media Players is a contentious issue and one that will be of varying importance depending on how you plan on using the player.
Gigabit LAN in Sigma 864x Players - (LAN 100*)
All the new players based on the Sigma 864x chipset claim that they are capable of LAN 1000 Mbit/s (Gigabit LAN). We believe that this is simply not the case. If you look at the Sigma 864x chipset specification (here) you will see that the only 864x chip capable of Gigabit LAN is the SMP8647, which is not used by any Media Player.
The highest bitrate files you are likely to come across for HD video are around 50 Mbit/s so a decent LAN 100 Mbit/s connection is more than adequate. Therefore the only area in which a Gigabit LAN connection will make a difference is in transferring files across the network.
For the sake of accuracy we have changed the specifications on all 864x players to LAN 100* as we feel this more accurately reflects true capabilities.
Wireless Networking
Wireless networking is generally not reliable enough for streaming HD audio, therefore it is not recommended for Media Players. We are not saying that it won't work, just that you may encounter stuttering problems with some video. Of course, using Wi-Fi to copy files across a network will work fine. For this reason most Media Players omit Wi-Fi from their specifications and instead offer optional support via a USB dongle.
The maximum data transfer rate for Wi-Fi(n) is 54 Mbit/s with actual achievable rates usually being less than half of this.

This player has wireless N (Draft 2). It is faster than 54 Mbit/s when used wirelessly. philip June 10, 2010 - 21:04
Re: LAN100 being enough for 50Mbits/s. First, maximum LAN utilization is far below 100%, so given 100Mbits/s you probably have about 70Mbits/s. More importantly, if you want any advanced features like buffering you want it to be faster then actual playback rate. Video transfer over network is perfect for jumbo frames which can be utilized only in Gigabit LAN. Leave a Comment
