There shouldn't be as far as I'm aware of. As far as connectivity is concerned, the wifi-only versions follows the 802.11 b/g/n standards. The 2012 version can operate at 2.4 GHz, while the 2013 version can operate in either 2.4 GHz and/or 5 GHz.
There are two of them 2.4 GHz and 5 GHz.

The 5 GHz frequency can travel up to about 150 feet (45 meters) indoors and around 300 feet (90 meters) outdoors, but its range is significantly affected by physical obstacles like walls and furniture. Compared to 2.4 GHz, the 5 GHz band has a shorter range due to higher frequency signals having more difficulty penetrating obstacles. Additionally, environmental factors and interference from other electronic devices can also impact its effective range.
The result of 5 GHz wavelengths being shorter than 2.4 GHz wavelengths is that they can carry more data and are less prone to interference, making them better for high-speed wireless communication.

Part of the infrared spectrum, called "Far Infrared".300 GHz is approximately where high-frequency radio waves turn into infrared light.300,000 GHz is where infrared turns into visible light.List of frequency spectra: See related link.
There are only two of them 2.4 GHz and 5 GHz.
No. You need an Intel i5 2500k overclocked to at least 5 GHz to run 3dmax.
802.11a
The IEEE 802.11a specification applies to the 5 GHz frequency band. The U-NII has the ranges blocked in at 5.15 to 5.25 GHz, 5.25 to 5.35 GHz, 5.47 to 5.725 GHz and 5.725 to 5.825 GHz. Throughput is in spec'd at 27 MBits/second. Below you'll find links for more information.
