To "bond" your three questions... Quote:

That standard describes the type of modulation and the support for MIMO. Yu can still have a 802.11n radio using a single chain (one antenna) or two or more chains using multiple antennas. Quote:

From reading some literature it appears yes using transmit beamforming and spatial multiplexing in order to achieve these higher bandwidths. | 150 Mbps is about as fast as any single-chain radio path will support. When you aggregate two paths, you get 300 Mbps. There isn't any "beam-forming" per se as one would discuss it professional grade radios - it's more of an advertising phrase for consumer gear. to reduce interference between the two paths, they use spatial and polarization diversity.

Or can you get this using 2.4? | Higher data rates require a wider channel width. On 2.4 GHz, a 40 MHz wide channel will hog the entire band, and in a dense apartment complex that is just not gonna work. On 5.8 GHz, you have a much wider band that let's you take advantage of wider channel widths.  |
