    Wi-Fi Is About to Get Faster
    [​IMG] 10 hr ago By Brendan Sasso of National Journal





    It will soon be easier to stream videos and browse the Web on Wi-Fi networks.
    The Federal Communications Commission voted unanimously on Monday to set aside more airwaves for unlicensed services like Wi-Fi, a move that will ease congestion and boost speeds for smartphones and laptops.
    FCC Chairman Tom Wheeler described the agency's action as "spinning straw into gold."
    "This opens all kinds of new opportunities for entrepreneurs and innovators as well as relieving congestion," Wheeler said. "Faster connections, less congestion all make it easier to get online."
    Exploding wireless Internet traffic has clogged Wi-Fi networks in recent years and made it difficult for people to connect to the Internet, especially in crowded areas like convention centers and airports.
    Under the FCC's order, Wi-Fi routers will have access to an additional 100 megahertz of spectrum—the radio frequencies that carry all wireless signals. The spectrum, which is the 5 gigahertz band, had been licensed to the satellite phone provider Globalstar, but the company agreed to the new rules after the FCC set interference standards.
    "While that sounds technical, this change will have real impact," said Democratic FCC Commissioner Jessica Rosenworcel.
    "For starters, if you like Wi-Fi, that is a lot more. Cheers for that. But the power of unlicensed goes beyond onramps to the Internet and offloading for licensed services. It is the power of setting aside more of our airwaves for experiment and innovation without license. It is bound to yield new and exciting developments. It is also bound to be an economic boon."
    Unlicensed spectrum can be used by any company for free and powers a variety of technologies such as baby monitors and remote controls. But Wi-Fi accounts for the vast majority of traffic that travels over unlicensed spectrum and was what spurred the FCC to enact the new rules.
    The FCC's action will not help services like cellular networks that rely on licenses for exclusive use of spectrum. But the FCC officials said they expect the demand for unlicensed spectrum to continue to explode in the coming years as more everyday devices like refrigerators and thermostats connect to the Internet.

    I wonder what John Cioffi will do with this new spectrum allocation?

    The above article is correct. The congestion and slow connection speeds do make it harder to get online. As more is done as the article says and some of it does currently exist. Your smart phone can turn on items at your home. Set the thermostat, turn on lights, unlock doors etc. Consider the differences of using 2.4Ghz or 5Ghz.
    ================================
    Is 5GHz Wireless better than 2.4GHz ?

    Wireless computer network equipment typically uses radio signals in either a 2.4 GHz range or a 5 GHz range.

    The GHz range of a wireless radio is only partially related to the speed of a wireless network. For example, routers have the capability of simultaneous dual-band operation on both 5GHz and 2.4GHz ranges, allowing clients to connect on different bands for more flexibility and less interference. 802.11ac expands on that, running entirely in the 5GHz band.

    Advantages of 5GHz:
    The 5GHz band is less likely to be congested. The 2.4GHz frequency range is much more prone to interference, as it is commonly used by other wireless networks in the area, as well as cordless phones, garage door openers and other home appliances and consumer products. The 5GHz band can also offer much higher throughput (using the right technology) with the same channel width.

    Disadvantages of 5GHz:
    In general, the higher the frequency of a wireless signal, the shorter its range. Thus, 2.4GHz networks cover a substantially larger range than 5GHz wireless networks. In particular, the higher frequency wireless signals of 5GHz networks do not penetrate solid objects nearly as well as 2.4GHz signals, limiting their reach inside homes. Recent 802.11ac devices may be able to mitigate some of this disadvantage by using beamforming.

    The Bottom Line:
    5GHz and 2.4GHz are simply different frequencies, each with its advantages and disadvantages. To get the best of both worlds, some recent routers have the capability for dual-band operation in both ranges simultaneously. 5GHz offers higher throughput at a shorter distance, while 2.4GHz offers increased coverage and higher solid object penetration.
    ==========================================================
    While the spectrum will open up. The problem is the 5Ghz does not penetrate buildings as well as 2GHz frequency's will. So what can be done right now to optimize your connection? What can be done right now to find the sweet spots, in your home , where you are setting up your router? What is available right now for free to help in all of this?

    John Coiffi has introduced a new application that can be downloaded for free that will. Relieve consumers from the pain associated with slow Internet speeds by running a series of diagnostic tests to identify the bottleneck. It has a feature that locates the fastest and slowest Wi-Fi spots in a room. Users simply tap “start” to begin their Wi-Fi Speed Scan and can probe the environment around them to understand how Wi-Fi speed fluctuates over time and location relative to their access point.

    So then the advantages of this extra band width is dependent of your home or office?
