Wi-Fi Adapter Best Practices
Wi-Fi Signal Strength and Range
The Wi-Fi dongle antenna radiates from the plastic window of the outer housing. Maintaining a
clear path between a Wi-Fi Dongle antenna and the client provides the best connection. Signal
strength can vary depending on obstructions, such as walls, bodies, metal, etc. The maximum
range of the Wi-Fi Dongle is around 250 feet in line-of-sight conditions.
Wi-Fi Channel Interference Mitigation
The Wi-Fi dongle configuration sets the access point mode and channel setting to Channel 1
within the 802.11g framework. Many wireless devices, including routers, keyboards, mice, etc.,
default to Channel 6 from the manufacturers. Potential interference issues may be experienced
if operating the Wi-Fi dongle in close proximity to these devices that communicate on a separate
network using Channel 6. If available, configure your other wireless devices to operate on a
different 802.11g channel. Channels 1 and 11 provide ideal non-overlapping operation with
Channel 6. The diagram below shows the channel center frequency and their channel
bandwidths.
The TW-1760 operates in the 2.4GHz frequency band. TrellisWare radios can also operate in
this frequency range. For best performance, TrellisWare recommends using TSM operating
frequencies outside of the Wi-Fi band (2400 MHz – 2485 MHz) when the Wi-Fi adapter is
employed.
