RangeMax™ 240 Multiple-Input, Multiple-Output (MIMO)
Technology
NETGEAR’s RangeMax 240 Multiple-Input, Multiple-Output (MIMO) technology provides ten
times more coverage than standard 802.11g alone by eliminating “dead spots” in your area of
coverage. Your whole house or office suite now becomes a “hot spot” without requiring any range
extenders, repeaters, or external antennas. RangeMax maintains your high speed throughout your
home, not just when you are close to your router.
RangeMax 240 is a TRUE MIMO (Multiple Input, Multiple Output) technology that uses three
external antennas, capable of transmitting at speeds up to 240 Mbps. It can also transmit two
different data streams on the same channel at the same time, at speeds up to 126 Mbps, if you use
the WPNT511 or WPNT121 Wireless Adapters.
In "Up to 240 Mbps" mode the router uses channel expansion to achieve a data rate of 240 Mbps.
The channel expansion uses the channel selected as the primary channel and expands to a
secondary channel (primary c 4 or - 4) to achieve a frame-by-frame bandwidth of
40 MHz. The WPNT834 router detects channel usage and, if necessary, will disable frame-by-
frame expansion to avoid interference with the data transmission from other access points or
clients.
Note:
The maximum wireless signal rate is derived from the IEEE Standard 802.11
Specifications. Actual data throughput will vary. Network conditions and
environmental factors, including volume of network traffic, building materials
and construction, and network overhead, lower actual data throughput rate.
