Dual band WiFi vs Triband WiFi-Difference between Dual band wifi and Triband wifi

This page compares Dual band WiFi vs Triband WiFi and mentions difference between Dual band WiFi and Triband WiFi. It also mentions triband phone vendors or manufacturers.

The wifi network consists of wifi routers or Access Points(APs) and wifi stations (STAs) or clients. There are two different modes in which routers and clients communicate viz. adhoc and infrastructure. Adhoc is peer to peer communication or mesh mode while infrastructure is like star communication. Refer Adhoc vs Infrastructure➤.

WiFi uses 2.4 GHz, 4.9 GHz and 5 GHz frequency bands in various WLAN implementations viz. IEEE 802.11a, 11b, 11g, 11n across the globe.

WLAN infrastructure mode

Dual Band WiFi

• The term Dual band wifi is most commonly used term for wifi routers.
• These routers uses two wireless bands viz. 2.4 GHz and 5 GHz.
• Dual band wifi routers support more number of devices (i.e. STATIONs).
• There will be less interference as there are two operating frequencies which are wide apart in the network. These frequency bands are assigned to various daily (tablets, laptops, smartphones) and non daily devices (printers, cameras etc.)

TriBand WiFi

• The term Triband wifi is also used with wifi router and stations.
• These routers uses three wireless bands viz. one 2.4 GHz band and other two 5 GHz bands.
• Triband wifi routers accommodate more number of wifi devices/stations compare to dual band wifi.
• Due to three bands more speed can be achieved.

There are various triband phone vendors or manufactures. The popular among them are Samsung, Lenovo, Motorola etc. These phones support three cellular frequency bands for different wireless technologies/standards.
