802.11ac Wi-Fi Explained – What Is It & Why It’s Cool Posted: 04 Jul 2013 06:01 AM PDT At Apple’s latest WWDC, we heard them announced the new OS X Mavericks and iOS 7, but what some might have missed is their new MacBook Air with 802.11ac Wi-Fi. If you don’t already know, Wi-Fi has a few standards, 802.11a/b/g/n. The latest and greatest is 802.11ac which is supposed to be much faster than 802.11n, currently the best on the market. What inspired this great naming sequence, we have no idea.
But we are here to explain what 802.11ac means. Other than speed, there are a few new technological breakthroughs that 802.11ac can accomplished. 802.11ac Explained For Easy Understanding802.11ac can also be referred to as wireless-AC and is called Gigabit Wi-Fi, a step up from previous generations that were in the Megabit range (1 Giga = 1024 Mega). This makes the new standard roughly three times faster than wireless-N.
However, the speeds are only theoretical maximums as there are many variables and factors that can cause it to slow down. Speedbump FactorsThese factors can come from
These factors are hard to overcome completely, so wireless-AC tries to ‘overpower’ it by having supercharging the hardware and by bringing in more tech advancements. Wider ‘Highways’Wireless-AC has wider bandwidth capabilities of 80 MHz (and an optional 160 MHz). By comparison, Wireless-N’s bandwidth was only at 20 or 40 MHz. To explain this concept, imagine the MHz as lanes on a highway: 20 MHz represents 2 lanes and 80 MHz represents 8 lanes. The more lanes you have, the higher amount of data can pass through at the same time, thereby allowing you to maximize your connection speed.
Crowded FrequenciesOn top of wider bandwidth, wireless-AC runs on the 5 GHz frequency band which is not as crowded as the 2.4 GHz band. The latter is crowded by signals from cordless phones, Bluetooth headsets, baby monitors, remote door openers and almost every wireless thing in your home. Most consumer products go for the 2.4 GHz because the higher frequency of 5 GHz meant it has shorter range and does not penetrate solid objects well. Beam Me Up ScottyTo overcome the limitations of using the 5 GHz frequency band, wireless-AC has a feature called Beamforming. Imagine wireless technology as a wave that spreads outwards, towards the router. Beamforming focuses on a specific direction instead, and via more than one transmitting antenna, thereby effectively strengthening the signal without any extra power consumption.
MU-MIMO Top UpThe use of Beamforming then gets more efficient with Multi User – Multi Input Multi Output (MU-MIMO). MIMO isn’t new, but MU-MIMO allows communication with 4 different devices at the same time compared to only one device previously. More devices can connect to a single router, with less interference or conncetion disruptions. Where 802.11ac Can ExcelOur homes are turning wireless, with devices like Smart TV, gaming consoles with wireless controllers, wearable technology and even smart locks for the front door. These devices require wireless connectivity to run its functions. Wireless-AC can help overcome the number of devices we want connected and reduce interference for smooth connections between all the wireless devices. Note that unless you have a Gigabit internet connection, 802.11ac won’t let you surf the Internet on your wireless device much faster. Instead, it excels in wireless HD video streaming, gaming, syncing of devices, backups and sharing speed of large files between users on the same network. 802.11ac Devices In The Market NowApart from Apple’s latest MacBook Air and the upcoming refresh of the ASUS G75VW, other 802.11ac devices include the feature-filled Samsung Galaxy S4, HTC One, and the upcoming Samsung Galaxy Mega. There are also a few companies like D-Link, Netgear, Linksys, Belkin, Buffalo and ASUS that have routers in the market with support for wireless-AC alongside the older wireless-N. Apple’s new AirPort Extreme and Time Capsule have also been updated with wireless-AC support. Wireless-AC is backward compatible, which means most of your older devices would still work with a new 802.11ac router. However, in order to use wireless-AC at its full potential, you’ll need a device (PC, laptop, smartphone, tablet) that can receive the AC specification. For desktop PC users, ASUS has a PCIE network adapter for your motherboard. Alternatively, you can get USB solutions from ASUS and Netgear to get wireless-AC on your laptop. Note: Before purchasing any of these devices, you should read reviews of the devices to ensure you won’t run into any complications. Wrap UpPrice-wise, wireless-AC routers are not much more expensive compared to current routers but there are few wireless AC devices in the market. You should know that 802.11ac is not officially finalized yet and the devices currently available in the market are still based on working drafts. The same thing happened when 802.11n first released. So whatever wireless-AC devices you get now may not work at its full potential until it’s finalized. |
Send And Share Files Up To 1TB With SoShare Posted: 04 Jul 2013 03:01 AM PDT Sending large files over the net is no longer a problem and for most of us, Cloud storage is the solution that helps you bypass uploading and downloading times. That said in many cases to do with file sharing, the process is limited by the file size itself. The media that we deal with nowadays are so ‘heavy’ that yes, we one day may have to think about ways to send files that are 1 terrabyte big. Foreseeing this need, SoShare, a site powered by BitTorrent now offers you the option to send files up to 1TB in size. That’s 1024 Gigabytes (so you can skip googling it; you’re welcome). You don’t need an account and it is completely free to use now during its open beta phase. Recommended Reading: Securely Transfer & Share Large Files With BitTorrent Sync Sending Files with SoShareHead over to SoShare. Before you can add files to send, you will need to download and install SoShare for your browser first. You only need to install SoShare once in your system. SoShare works with:
To send your files, just type your email and your sender’s email. You can send the files to multiple recipients, just place a comma in between each email address. Then, click ADD FILES to start uploading the files you want shared. You can add multiple files until you hit the 1TB limit, but of course, the bigger the file is the longer the time it needs for the upload. Upload speeds depend on your Internet connection. However, note that you can pause the download and resume where you left off later. Multiple files will be bundled up so that the recipient can download all the files in a single click. Downloading the file also does not require any extra tools, just click to download. When the recipient starts to download the file, SoShare will notify the sender via email. If you sent the files to multiple recipients it will notify you which one of your recipient is downloading the file. Limitations & ConclusionWith SoShare your files will only be available for download for 30 days (1 TB is a lot) but it is a simple, disposable and great way of sending multiple heavy files in one go. It also has the option for you to make your files available to the public. Do keep in mind that SoShare is still in beta, so there might be more changes brewing behind the scenes. Let us know if you will be using it and what more you are expecting from the service. |
Easy Color Scheme Generation with Adobe Kuler for iOS Posted: 04 Jul 2013 12:01 AM PDT When designing, be it on the Web, for an app, or in a print product, we have to decide what colors to use on the design. There are a whole bunch of tools to help you pick the right color scheme for the job but what about one that helps you pick color schemes right from your iOS devices? Adobe Kuler, one of the most popular color scheme generators known among designers, has launched a free iOS app that lets you generate color schemes right on the iPhone and iPad, iOS 5.1 and above. And after having a go with the app, I have to say I’m impressed with its simplicity. Recommended Reading: Practical Approach To Choosing Website Color Scheme Creating Color SchemeUnike the Web app, Adobe Kuler for iOS helps you retrieve colors from a photo, and even generates the color scheme instantly while we are taking a picture. Unless you are taking photos with a tripod, chances are the picture on the screen will be a little shaky and the color scheme will also keep changing. To freeze the picture, tap on the screen. Then, move the color dots to the capture different colors from inside the picture. To automate this, make changes at the menu found at the bottom right of the app. Adobe Kuler can be set to capture the color scheme when a picture has been taken. This also works with photos that have been previously taken. After the color scheme has been generated, the colors can be adjusted. The rules of adjustment can be changed to Analogous, Triad, Monochromatic or Complementary to generate different combinations. Apart from taking color schemes from a picture, this app also allows you to create a color scheme from the color wheel – just like in the Web app. Saving Color SchemeBy default the generated color scheme is saved locally in your phone. But, you can share it in Adobe Kuler using an Adobe ID. You can also set whether your collection of color schemes is viewable publicly. Final ThoughtWhen using Adobe Kuler for iOS generating a color scheme becomes a lot more convenient. It is a really solid app, easy to use, and even has more capabilities over the Web app. Give it a try and let us know if you agree. |
