devices like computers, microwaves, and televisions increase
interference significantly, especially on the 2.4GHz band.
The half-duplex nature of wireless combined with other
overhead also means that the actual aggregate throughput is
typically 50 percent or less of the data rate. It is theoretically
possible for 802.11n-capable wireless clients to achieve
speeds as high as 100Mbps or more depending on the MIMO
capabilities of the AP and the wireless client. However,
wireless clients operating at 802.11b/g/a can cause 802.11n
users to slow to less than 54Mbps because the radio must
adjust to the lowest common denominator.
The nature of Wi-Fi technology makes throughput hard to
predict. Therefore, network administrators should maintain
reasonable expectations for connection speeds and keep the
above factors in mind.
Maximizing Throughput
Optimal throughput rates and wireless performance in general
can be improved by mounting APs correctly (high up on a wall
or on the ceiling). Additionally, placing APs away from
kitchens and other areas with high interference will also result
in better performance. In a mesh environment, throughput
rates will be significantly better with fewer hops to the
gateway.
Meraki recommends that the end user is located no more
than 3 hops away from the gateway. Each hop will reduce the
bandwidth by 50%. For example, a 6 Mbps connection to a
gateway will reduce to 3 Mbps at the second hop and 1.5
Mbps at the third hop.
