Protocols
There are several different and incompatible protocols for audio over Ethernet. For example, using category 5 cable and 100BASE-TX signaling at 100 Mbits/second, each link can generally transmit between 32 and 64 channels at a 48 kHz sampling rate. Some can handle other rates, such as 44.1 kHz (CD-quality), 88.2 and 96 kHz (2× oversampling), even 192 kHz (4×), as well as up to 32-bit samples, with a corresponding reduction in channel capacity. On some, this is accomplished through channel bonding, while others use individually scalable channels.
AoE is not necessarily intended for wireless networks, thus the use of various 802.11 devices may or may not work with various (or any) AoE protocols.
Protocols can be broadly categorized into Layer 1, Layer 2 and Layer 3 systems based on the lowest layer in the OSI model where the protocol exists.
