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?

Introduction:
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.

60GHz RF channels

• 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.

Feature Class-1 Class-2 Class-3
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
Number of modes 7 5 2

60 GHz device classes as per ECMA 387

Following table-2 mentions 60 GHz device classes viz. class-1, class-2 and class-3 as per ECMA 387.

Feature Type-A Type-B Type-C
Maximum Range 10m NLOS 3m LOS 1m LOS
Data rate 3.97 to 6.35 Gbps 0.794 to 3.175 Gbps 0.8 to 3.2 Gbps
Receiver sensitivity -60 dBm -60.7 dBm -62.2 dBm
Modulation BPSK/QPSK/8QAM/16QAM DBPSK/DQPSK OOK/4ASK
Number of modes 14 5 3
