As the commercial population becomes more mobile, two trends have emerged for Wi-Fi solutions to address:
Mobile applications now demand more bandwidth – Video and voice applications have increased the demand for pervasive bandwidth...everywhere.
Individuals carry multiple wireless devices – With an average corporate mobile device/user ratio approaching 2.7 (laptop, tablet, and/or smartphone), client congestion has become a problem for wireless networks.
The challenge for 802.11ac is to meet today's functional demands and the explosive wireless market growth that is expected over the next three to five years.
@Michael- as you said mist companies use gig networks. But the best part is having gig network over Wi-Fi, that's pretty amazing and useful. Most company executives use portable devices to make their life easy; they probably carry it around the office for presentations etc. I think gig network over Wi-Fi would really help them be connected to the network.
Unless you are referring to consumers. A large percentage of businesses are running gig networks due to VoIP and video teleconferencing. Wi-Fi is only important when individuals are away from their desk.
I would say, once 11ac is well established and prove itself it can be utilized in local area quite effectively. If the throughput can reach a stable 100 Mbps than that would replace good amount of wired LAN.
This increase in speed is achieved by providing wider frequency bands, faster processing, and multiple antennas. Think of it in terms of an automotive highway, where a transition is made from a highway with four lanes to one with eight lanes, while simultaneously upgrading to a Ferrari on an auto-bahn highway with no speed limit. The result is faster traffic and significantly reduced congestion to enable a decrease in overall travel time.
In contrast, the new 802.11ac standard can achieve more than three times the performance of the current standard, with speeds up to 1.35 Gigabits per second. What's more, 802.11ac has the capability to maintain a higher level of performance at any range, compared with its predecessors.
The array of multimedia use cases and increasing number of devices commands greater performance. The most powerful 802.11n devices cap out today at a maximum link rate of 450 megabits per second at close range, with declining performance as the range increases.

Recently, the Obama administration has been of two minds where privacy rights are concerned. On one hand, you have an administration that vowed to veto CISPA and mandated open data for government websites. On the other hand, you have an increasingly out-of-control Department of Justice on a fishing expedition at AP and demanding legislation to let the FBI wiretap private, encrypted communications and levy fines if a company fails to comply.
The apartment and house sharing service, Airbnb, now requires members to verify their identities by demonstrating a presence on the web, and by either scanning a government ID or entering detailed personal details. Other enterprises should take a close look at Airbnb's verification policies.
Facebook advertising is a lightning rod. It seems neither brands nor consumers are 100 percent happy about the social media site's policies, placement, or procedures. But the real controversy about Facebook ads and promotions is over whether they work.
By now, you've most likely heard about the 3D-printed gun that Texas-based Defense Distributed demonstrated last week. But we haven't heard the last about the censorship war that began soon afterward.
New York's Metropolitan Transit Authority is conducting a pilot test of digital kiosks to guide subway users to where they want to go more efficiently and at lower cost.
The whole Amazon.reader debate is a double-stupid. It's stupid to think that there's any e-book buyer who doesn't know Amazon's URL, and it was stupider to let ICANN launch the whole free-form TLD initiative to start with.
While NFC's original goal was to enhance mobile commerce applications, it is finding its way into a number of other uses, which is creating both opportunity as well as challenges for IT departments.

Subsidized handsets, rather than locked handsets, should be the focus of regulators. We're not getting good deals, not fostering innovation, and weakening our power as buyers.
