reply from X-Micro re "extended range function"
The "extended range" technology is a method for processing 802.11 signals
that enables wireless networks to have fewer "dead spots" and greater range
than typical 802.11 products; in effect, a "low gear" for wireless networks.
The basic methods of processing wireless signals as defined by the IEEE
802.11b and 802.11g standards are optimized for the delivery of signals in
environments where signal strength is strong. As range increases or walls
intervene, signal strength drops, but the same basic signal processing
methods are used. This is why "dead spots" ocurr in wireless networks and
why the connection drops abruptly at longer rates.
When extended range is enabled, the router dynamically adapt to sub-optimal
environments and process weaker signals more effectively. As a result,
extended range greatly increases the coverage of your 802.11g network.
Extended range builds upon 802.11g by adding transmission rates equivalent
to 3, 2, 1, 0.5 and 0.25 Mbps. As with typical operation, these new rates
are added to the list of rates used by the router's adaptation algorithm to
maximize throughput while maintaining reliable data transmission. This rate
adaptation automatically engages as required to mitigate the effects of
distance, obstacles and interference.
