The FCC's move to release more 5 GHz frequencies for gigabit Wi-Fi use reflects efforts to develop and employ spectrum-sharing techniques to open up encumbered frequencies. It also highlights the ongoing battle between parties advocating for licensed vs. unlicensed spectrum allocations.

The following technologies are the hottest ones in the industry right now, generating support from carriers, device makers and network vendors. Some of these technologies were introduced in 2012 or even before, but we think that they will gain widespread attention and adoption in 2013.

The Wi-Fi Alliance certified 25 percent more products during 2012 than 2011, led by 64 percent year-over-year growth in certifications for devices in the consumer electronics (CE) category. The handset category drew a 34 percent year-over-year jump in certifications.

The FCC moved to satiate the public's growing appetite for Wi-Fi by promising to unleash 195 MHz of spectrum in the 5 GHz band, which the commission contends will alleviate Wi-Fi congestion at major gathering places and enable higher data speeds and greater capacity for "Gigabit Wi-Fi" applications.

Qualcomm Atheros and Wilocity unveiled what they claim is the first tri-band reference design combining 802.11ac Wi-Fi and 802.11ad WiGig wireless capabilities on a single module.

Apple reportedly intends to add 802.11ac chips from Broadcom to its 2013 Mac computer lineup and is also planning to add a bevy of colors and screen sizes to its iPhone lineup.
