WLAN on 60GHz Frequency Bands

A method comprising, by a module of a first wireless communication device:

• receiving, from an RFIC associated with the first wireless communication device, RF signals received from a second wireless communication device, wherein the RF signals comprise k orthogonal channel bands, and wherein k is two or more;
• converting the RF signals into IF signals by converting signals from each of the k orthogonal channel bands into each of k spatial layers;
• and
• sending the IF signals to a wireless modem associated with the first wireless communication device, wherein the wireless modem decodes the data from each of the k spatial layers.

One or more computer-readable non-transitory storage media embodying software that is operable when executed to, by a module of a wireless communication device:

• receive, from a wireless modem associated with the wireless communication device, intermediate frequency (IF) signals for k spatial layers to be transmitted, wherein each of the k spatial layers occupies a pre-determined bandwidth, and wherein k is two or more;
• convert the IF signals into radio frequency (RF) signals by converting each of the k spatial layers into each of k orthogonal channel bands, wherein neighboring two channel bands among the k orthogonal channel bands are separated by a pre-determined frequency separation that is large enough to avoid interference between the two channel bands;
• and
• send the RF signals to a radio-frequency integrated circuit (RFIC) associated with the wireless communication device, wherein the RFIC transmits the RF signals wirelessly.
