●Transmission Rate
Setting a high-speed communication rate will narrow the area where the Handy Terminal can
perform transmission.
The rate setting on the Handy Terminal side decides whether 14ch can be used, and the rate
setting on the access point side affects the connectivity.See the following table.

◎ : Connectable.The 11g rate will take precedence, and high transmission rate is possible.
○: Connectable.Communication is performed at the 11b rate.
△ : Connectable.The throughput is reduced somewhat due to negotiation of 11b/g.
×: Non-connectable.
