type	fréq	min/max power	antenna gain	Ethernet	POE	norm	channel sizes	max speed (level)	min sensitivity (speed)	proprietary	notes
Bullet-2	2.4 GHz	20 dBm	0	10/100BaseTX	4 W passive 4,5+; 7, 8 return, max 24V	802.11b/g OFDM	5, 10, 20 MHz	54 Mbps (-72 dBm)	-95 dBm (1 MBit/s)		TX speeds above 24 Mbit/s lead to TX power cap ()
Bullet-5	5 GHz	22 dBm	0	10/100BaseTX	4 W passive 4,5+; 7, 8 return, max 24V	802.11a OFDM	5, 10, 20, 40 MHz	54 Mbps (-74 dBm)	-94 dBm (6 MBit/s)		TX speeds above 24 Mbit/s lead to TX power cap (4 dB)
Bullet-5M	5 GHz	25 dBm	0	10/100BaseTX	6 W passive 4,5+; 7, 8 return, max 24V	802.11a/n	5, 10, 20, 40 MHz	54 MBps (-75 dBm) a; MCS7 (-74 dBm) n	-83 dBm (24 MBps) a; MCS0 (-96 dBm) n	Airmax TDM; Airview	TX speeds over MCS4 (11n) or over 24 Mbit/s (11a) lead to power cap of 4 (a) or 6 (n) dB; -40 C
Nanostation Loco M5	5 GHz	23 dBm	13 dBi	10/100BaseTX	5.5 W passive 4,5+; 7, 8 return, max 24V	802.11b/g	5, 10, 20, 40 MHz	54 MBps (-75 dBm); MCS15 (-75 dBm)	-83 dBm (6 MBit/s); -96 dBm (MCS0)	Airmax TDM; Airview	TX speeds over 24 Mbit/s (bg) or MCS3 cap the TX for upto 5 dB
Powerbeam M5-400	5 GHz	26 dBm	25 dBi (400 mm)	10/100/1000BaseTX	8 W; GBit POE	802.11a/n	5, 8, 10, 20 30, 40 MHz	54 MBps (-75 dBm); MCS15 (-75 dBm)	-94 dBm (6 MBit/s) a; MCS0 (-96 dBm) n	Airmax TDM; Airview	Antenna is 40 cm wide; -40
Nanobeam M5-19	5 GHz	26 dBm	19 dBi (190 mm)	10/100BaseTX	8W passive 4,5+; 7, 8 return, max 24V	802.11a/n	5, 8, 10, 20 30, 40 MHz	54 MBps (-75 dBm) a; MCS15 (-75 dBm) n	-94 dBm (6 MBit/s); -96 dBm (MCS0)	Airmax TDM; Airview	-40

Probably the TX cap on high speed has no impact because we always mount this with a gain antenna and abide by legal max power transmission limits.

Data rate MCS definitions in 802.11n:

MCS	channel width	Mbit/s
MCS0	20/40	6.5/13.5
MCS3	20/40	26/54
MCS4	20/40	39/81
MCS7	20/40	65/135
MCS15	20/40	130/270
