60 GHz device classes-class 1,class 2,class 3,type A,type B,type C
This page covers 60 GHz device classes as per IEEE 802.15.3c and ECMA 387 viz. class 1, class 2, class 3, type A, type B and type C.
What is 60GHz?
Following are the features of 60GHz frequency.
• This particular frequency falls in millimeter wave range (i.e. 30 GHz to 300 GHz) in the electromagnetic frequency spectrum.
• It falls in globally used unlicensed band viz. 57 to 66 GHz recently adopted across the world for commercial use for wireless communication.
• 60GHz wavelength is about 0.5 centimeters.
• It is also known as V-band frequency.
• It is used for low power and short distance communication.
• There four popular channels viz. each having about 2 GHz of bandwidth.
60 GHz device classes as per IEEE 802.15.3c
Following table-1 mentions 60 GHz device classes viz. class-1, class-2 and class-3 as per IEEE 802.15.3c.
The IEEE 802.15.3c standard defines three classes of modulation and coding schemes for SC (single Carrier) mode in
mmwave PHY as mentioned below.
• Class-1 is used for low power, low cost mobile for data rate requirements upto 1.5 Gbps.
• Class-2 is used for data rates upto 3 Gbps.
• Class-3 is used for data rates in excess of 5 Gbps for high performance apps.
|Data Rate||<1 Gbps||Between 1.5 Gbps to 3 Gbps||Between 3 Gbps to 5.5 Gbps|
|Receiver Sensitivity||-65 dBm||-58 dBm||-50 dBm|
|Modulation||π/2 BPSK/GMSK||π/2 QPSK||π/2 8PSK, π/2 16QAM|
