The most widely used metric to compare these technologies is the physical rate. Nevertheless, this metric does not reflect the peculiarities of each MAC protocol, which limit the bandwidth actually available to users. In this article, we analyze different home networking technologies taking the main features of their MAC protocols into account. We have chosen the saturation throughput as the basic metric and have provided analytical results. Then, through simulations, we have varied the number of nodes in the network to verify how each protocol deals with contention and to analyze their efficiency. Results show that collision-avoidance protocols have lower efficiency than collision-detection protocols. Nevertheless, there may be exceptions. HomePNA 3.0 has a relatively low efficiency because it uses the same basic rate as HomePNA 2.0, to keep compatibility. The same happens within a protocol family; IEEE 802.11g at 54 Mbps is less efficient than IEEE 802.11b at 11 Mbps.</span> ER -
