he following specifications are true about the IEEE802.11n WiFi mode:

	a.	2.4/5 GHz operation bands, supports up to 600 Mbps data rates, uses HT-OFDM spread spectrum technology, uses SISO radios, and is backward compatible with the a, b, and g WiFi amendments.
	b.	2.4/5 GHz operation bands, supports up to 600 Mbps data rates, uses HT-OFDM spread spectrum technology, uses MIMO radios, and is backward compatible with the a, b, and g WiFi amendments.
	c.	2.4 GHz operation band, supports 1 and 2 Mbps data rates, uses OFDM spread spectrum technology, uses SISO radios, and is not backward compatible with the previous WiFi amendments.
	d.	5 GHz operation band, supports up to 6.93 Gbps data rates, uses VHT-OFDM spread spectrum technology, uses MIMO radios, and is backward compatible with all previous WiFi amendments.
	e.	2.4/5 GHz operation bands, supports up to 600 Mbps data rates, uses ERP-OFDM spread spectrum technology, uses MIMO radios, and is backward compatible with the b and g WiFi amendments
