ERB9250 802.11b/g/n Range Extender
• 2.4 GHz
• 300Mbps
• 11N Repeater/
client bridge
PRODUCT DESCRIPTION
ERB9250 is a 2.4GHz 802.11b/g/n 300Mbps Repeater & Client Bridge
(Range Booster / Extender). Range Extender solves the signal attenuation
(limited coverage) problem by literally repeating / extending AP radio
signal to dead-spots. While repeater clones AP and serves as a
subsidiary entity to its clients, client bride offers an extension of wired
network to the AP.
