Philips Hue Personal Wireless Lighting Review

Posted by Andrew at 12:51 AM on December 16, 2013

Kevin Ashton coined the phrase “The Internet of Things” back in 1999, but a decade later most of the on-line gadgets in my house are still recognisable as being technology. My fridge is still a fridge, my front door still needs a key and my house doesn’t talk to me.

That was the situation until a couple of weeks when I received a Philips Hue “Personal Wireless Lighting” kit which lets me control the colour of light bulbs from my smartphone, both in the house and from outside across the internet. That’s the Internet of Things.

I can imagine that a number of GNC readers are going, “Huh? Why would I want to control the colour of my lightbulbs from my smartphone?” Until you see in action, you can’t believe how much fun and how cool it really is. Not only can you turn your house lights on as you drive up the road, you can co-ordinate the lighting with your mood or your decor. Want a Christmassy green and red? Not a problem. We’ll see exactly how it works a little later on.

So let’s take a quick look at what’s in the box of Philips Hue in more detail.

Philips Hue Box Exterior

Opening it up reveals two of the three main components, the wireless bridge and the bulbs themselves.

Philips Vue Interior

The bridge connects to your network via an ethernet cable and communicates with the light bulbs using Zigbee.

Hue Bridge

The bulbs are standard ES bulbs and there are GU10 and GR30 (SES) variants available as well. There doesn’t seem to be any bayonet cap versions (BC) so if you only have BC light fittings you might have to get some converters.

Hue Light Bulb

Setting up the system is very easy. Screw the bulbs into the lights. Connect the Hue bridge to the network with the ethernet cable and plug in the power adaptor. Load the Hue app onto your Android or iOS smartphone or tablet. Job done. It’s that straightforward. The first time the app runs, it looks for the Hue bridge on the network and once it’s found, you authorise the app to access Hue by pressing the button in the middle of the bridge. It’s a layer of security that stops unauthorised people or apps from accessing the Hue.

The Hue app lets you control all the lights connected to your bridge mainly via “scenes” which act as presets for each light’s colour settings. Here’s the main screen. Each mini photograph is a preset for a number of lights and it can be just one or all three.

Main Screen

Typically the settings are based on colours picked out from the picture associated with the scene. The screenshot below shows that lamp 1 will be orange and lamp 2 will be magenta.

Colour Scenes

It’s all a bit abstract until you see it in action, so here’s a short video of my controlling one lamp using a series of the scenes to run through some colour changes. It was filmed with my smartphone, so don’t expect too much! Remember too, that this is just one light  and try to imagine all three lights working together to colour a single room.

Philips have opened up Hue to developers and are steadily building an ecosystem around both their products and other apps developed by third parties. If you are already have a Philips TV with Ambilight, Hue can further enhance the experience with additional colour lighting. Light strips and Philip’s Living Colors Bloom can take the lighting effects beyond lights and lamps.

There’s a solid community behind Hue with people contributing their own scenes and I’ll be taking a look at some of the 3rd party apps in a follow up post next week, along with a further look at the main Hue app.

Philips Hue is available from the Apple Store and the starter kit used here costs a little under £180, which isn’t cheap, but compared with the costs of some of the custom solutions in this space, it’s a bargain. Note that although it’s sold through the Apple Store, it works with both iOS and Android devices.

Finally, Philips are running a Facebook competition to come up with inspirational ways of using Hue, if you want to win some Hue goodies.

Thanks to Philips for the loan of the Hue starter kit.

TP-Link WiFi Powerline Extender Review

Posted by Andrew at 5:35 AM on December 9, 2013

From smart TVs to DVRs and games consoles, many items of consumer electronics now expect a network connection to download media or to upload hi-scores. Most homes don’t have ethernet cabling as standard and surprisingly few of these gadgets actually have wireless connectivity. Even then, it’s rare to have good signal throughout the house.

TP-Link Wireless Extender Box

This is where the TP-Link 300 Mbps AV500 WiFi Powerline Extender can come in, solving two problems at a stroke. First, for those who aren’t familiar with Powerline, it’s a technology that uses the mains electricity circuits to transmit network signals and as most homes have power sockets in every room, it’s ideal for spreading the network round the house. This kit (TL-WPA4220KIT) from TP-Link has two adaptors, one of which connects up to the broadband router and the other goes into the otherwise network-free room.

TP-Link Units in Box

But that’s not all….the room unit provides both wired and wireless services. A pair of ethernet ports on the bottom of the adaptor can hook up two cabled devices, say TV and DVR, and the wireless extender can strengthen the 11n network in the room to keep a games console happy. The kit can be extended with additional Powerline units to supply multiple rooms with networking.

TP-Link Side On

That’s the theory…how does it work in practice? Frankly, everything went very smoothly. Out of the box, the two units found each other and paired up across the house. The wireless unit has a clever clone feature where you press the WPS button on your usual wireless box and then the “clone” button on the front of the wireless adaptor. After a few seconds, the TP-Link adaptor then presents the same SSID and password as the existing box, but chooses a different channel to transmit on. To all intents and purposes, it appears that there’s a single wireless network in the area. Clever and very easy. (The configuration can be done manually as well.)

Performance-wise, I did some testing using Totusoft‘s Lan Speed Test. Bear in mind that no two homes will be setup the same, so while the Mbit/s figures are of interest, it’s the relative performance that matters. Remember, no-one gets real-world data transfer rates anywhere close to the headline rate because of the networking overheads. With that in mind, I tested the download speed from a Buffalo NAS to a Toshiba laptop using a 500 MB file. The figures are approx averages of a couple of tests.

  • Wired connection via standard ethernet – 146 Mbit/s
  • Wired connection via TP-Link Powerline – 72 Mbit/s
  • Wireless connection via TP-Link Powerline – 64 Mbit/s

I’m fairly impressed with those figures. Effectively, the throughput over the mains was about half what I’d get from an ethernet cable but 72 Mb/s throughput is pretty good, with the wireless not far behind.

For further comparison, I had a 200 Mb/s Belkin Homeplug system, which is a similar but slightly older technology.

  • Wired connection via Belkin Homeplug – 32 Mbit/s

Again, interesting. The Belkin is rated at 200 Mb/s with the TP-Link at 500 Mb/s. It’s perhaps unsurprising then that 32 Mb/s isn’t far off 2/5ths of 72 Mb/s.

And finally, I tried doing what you are warned against doing, namely plugging the TP-Link Powerline adaptor into an extension lead. I think the figures speak for themselves. Rubbish!

  • Wired or wireless connection via TP-Link Powerline in extension lead – 15 Mbit/s

Overall, the TP-Link Powerline units work well and they’re a good way to provide network connectivity to blackspots, both wired and wirelessly. The wi-fi clone feature makes it especially easy to setup. If you are getting some new gadgetry for Christmas that’s going to need a network connection, give this  Starter Kit a look. It’s available from all good retailers, including Amazon.co.uk for around £70. There is an older 200 Mb/s version that looks similar so make sure that you are buying the right one.

Note, all the figures above are megabits per second. No megabytes here, except for the download file size. Thanks to TP-Link for providing the Starter Kit for review.

Wireless 600 Mhz Spectrum Auction Impeding on Wireless Microphones

Posted by J Powers at 10:37 AM on November 27, 2013

wirelessA couple months ago I was at a conference recording interviews. I stopped and talked with another independent broadcaster to compare rigs. I noticed he had a wireless unit that was in the illegal wireless range. I told him about the spectrum auctions and how devices in that range interfere with the Emergency band. A week later, he notified me to say he got a new wireless to comply.

Hopefully its not in the 600 Mhz range…

The FCC opened up new spectrums for Auction. The 600 Mhz range (Channel 38 – 606 to 614 Mhz) is a spectrum that T-Mobile and Sprint are vying for simply because they only have a high-frequency ranges (in the 1900-2100 Mhz range). These low frequencies can push signals much farther, therefore, better call quality.

However, this new spectrum auction could affect those people who use wireless devices. Broadcasters, musicians or anybody that uses a wireless device might have to turn around and buy new equipment — if the wireless device is in the 600 Mhz range. Wireless devices affected could include microphones, instrument body packs and other high quality wireless devices. 

 

While no mention of emergency bands are going to be on the 600 Mhz spectrum, your device might see signal interference if used. Similar to hearing a TV or radio signal in a speaker when it shouldn’t be there (this was a running joke in the movie Spinal Tap as the amps would get interference all the time). If a caller was trying to contact emergency services, their call could be hampered because of other signals around them.

Sennheiser Asks for Compensation

Audio specialist Sennheiser has put together a petition to the FCC to compensate those people who own microphones using the 600 Mhz range. They stated the 700 Mhz spectrum change of 2010 forced people to buy new equipment and it is not fair to ask them to do it again only three years later.

These wireless devices can cost anywhere from $600-$2000. A TV station for example, can have several wireless devices to use so they can report the news. This could mean a replacement cost of $5,000 or more (more toward the $20,000 range), if all devices are on this 600 Mhz spectrum.

“Wireless microphones are an essential ingredient of content creation in the United States,” commented Joe Ciaudelli, spectrum affairs, Sennheiser Electronic Corp. “Currently, the United States is the number one content creator in the world when it comes to broadcasting, film production and live events. The A/V professionals that produce this content, which is enjoyed by both domestic and international consumers, depend on the 600 MHz frequency spectrum each day.”

Does My Equipment Use 600 Mhz?

So far from what I have reviewed, Sennheiser, Shure, AKG, Kam and some Sony wireless systems use the 606-614 Mhz range. These are mostly UK-based electronics, too. Other US based wireless UHF microphones use a lower channel (30-32) range.

If you do have equipment that meets the 606-614 Mhz range, it might be best to plan for a changeout. Talk with your representative about replacement options.

Microsoft Bluetooth Notebook Mouse 5000 Review

Posted by Andrew at 2:50 AM on October 31, 2013

Wireless mice are commonplace these days but many only work with their own brand wireless transceiver, which restricts their use to devices equipped with USB ports. Less common are Bluetooth-based mice which have the potential to work with any Bluetooth-equipped unit, including Android and iOS tablets, potentially making them much more useful. On review here is one such mouse, the Microsoft Bluetooth Notebook Mouse 5000. Snappy name, but let’s take a look.

The 5000 is fairly typical of notebook mice being smaller than a typical desktop mouse at only 9 cm long and about 5.5 cm wide. People with large hands may find the mouse is too small but for occasional use with a tablet or notebook, it’s fine. I certainly wouldn’t want it as my main mouse as I can’t really rest my hand on it, but this is all subjective and some people may find it perfect.

image

Looks-wise, it’s not a Microsoft Arc or a Logitech Ultrathin, but it’s not entirely unattractive. This is the version with silvery-white buttons and dark gray body; there is a version with these colours reversed too. The silver matched my Samsung Chromebook rather nicely but the colour does vary with the light.

Two Duracell AA batteries power the 5000, which are supplied in the packaging and Duracell’s make a welcome change from the generic AAs that usually accompany remote controls and other battery-powered accessories. There’s an on/off switch on the bottom to conserve power when not in use. I’ve been using the mouse for about a week and I’ve yet to replace the batteries.

To pair the mouse, there’s a second button on the underside that needs to be pressed for a few seconds to put the mouse into a pairing mode. After that, the mouse should appear in the device list of whatever computer is to connect to the mouse. I successfully paired with an Android tablet, a Windows 8 tablet and a Chromebook. I imagine that it will work with iPads and other iOS devices but I didn’t have one at hand to test.

image

In use, the 5000 works pretty much like any mouse. It’s an optical mouse with a laser motion tracker so resistance will depend entirely on the surface in use. There are four buttons: left, right, middle and “back”, which is next to the main left button and can pressed by your thumb to take your web browser back a page – you can see it in the top picture. Great if you are right-handed, but a waste of time if you are left-handed. The scroll wheel has a bit of stiffness to it but I like that as it prevents accidental scrolling.

Overall, the Microsoft Bluetooth Notebook Mouse 5000 is a good mouse but not a great mouse. It’s nothing special but there’s nothing wrong with it either (except for the back button only being useful to right-handed users) . The 5000 is available from all good retailers for around £25.

Disclaimer: this was a personal purchase.

Zens Qi Wireless Charger

Posted by Andrew at 4:29 PM on August 4, 2013

Although I was disappointed by the Nokia DT-900, I wasn’t ready to give up on wireless charging nirvana for my Nexus 4. With a bit of searching and review-reading, I plumped for a Zens Universal Qi Single Wireless Charging Plate which garners 4.5 stars on Amazon. Although unknown to me, Zens is a young Dutch company specialising in wireless charging products, and from first appearances, it looks like they’re doing a good job.

The Zens charging plate comes in a well-presented package but is surprisingly small. It’s bigger than the DT-900 but it’s still not large and I imagine that most large screen smartphones will overhang on one side or another. However, the extra size and the rubber covering mean that most smartphones will sit comfortably on the pad. As with the DT-900, it has a DC power supply – no USB charging here, either.

Nexus 4 on Zens Charger

In use, the Zens charging plate is far better with the Nexus 4 than the DT-900. In most instances, simply placing the the Nexus onto the pad started charging and usually, I’d get a high rate of charge without any precise positioning. With a bit of practice, I was able to get a sweetspot that worked every time and an LED on the right side of the plate turns green when the pad starts charging.

The screenshot below shows the charging rate when everything is perfectly aligned and honestly, it’s not far off the rate when the Nexus is plugged in.

Zens Charge Rate

The plate also has a feature that when the phone is fully charged, the charging turns off until the the battery levels falls to about 93%. Here’s what it looks like in Battery+.

Zens Wireless Charger - Full charge

In my opinion, the Zens charging plate knocks the DT-900 into a cocked hat, especially if you have a Nexus 4. Both are priced a little under £45 here in the UK, though the Zens charger seems quite pricey in the US at $100 (Amazon). Update – have since discovered the Zens charger on other websites for a far more reasonable $50. Recommended for all UK Nexus 4 owners.

LG Nexus 4 and Nokia DT-900 Wireless Charging

Posted by Andrew at 7:15 AM on July 22, 2013

Being an ex-Palm afficionado, I’m a massive fan of wireless charging. The convenience of simply placing a Pre onto a Touchstone to charge is unparalleled and I still use wireless charging with my Cyanogen-modded Touchpad.

Today, the Pre series is history thanks to HP, but wireless charging is still around with Samsung, LG and Nokia all supporting the Qi standard. My current phone is a Nexus 4 but the official orb charger is a small fortune here in the UK, so it was with interest that I saw that the prices of the Nokia DT-900 charging pad were gradually falling. Last week, I finally succumbed and bought one.

DT-300

First impressions are mixed. The DT-900 seems reasonably well-made with a single white LED at the front to indicate the status of the charging. Unfortunately, the DT-900 comes with a somewhat chunky power supply which connects via a cable with DC jacks at each end. It would be far more sensible and useful if it used micro-USB connectors. And who thought that a white PSU with a black pad was good idea?

DT-300 Charger

But on to the wireless charging….

Reports from elsewhere on the web suggest that the Nexus 4 and the DT-900 should work together but my experience was somewhat mixed. The main issue is that positioning the Nexus on the plate is crucial for the charging to ‘lock on’. Incorrect alignment causes the plate’s LED to flash and the phone will continually stop and start charging.

DT-300 Plus Nexus 4

I tried a wide variety of positions, but even when I managed to get everything lined up, charging was poor, as you can see from the attached screenshots from Battery+.

Screenshot_2013-07-21-21-01-25 Screenshot_2013-07-21-21-01-55

Best results were from putting the Nexus 4 on the pad such that about a quarter to a half inch of the pad is visible at the bottom, but even then the battery charge level seemed to hit a plateau at around 80%

Maxed Out

Overall, it was disappointing and the DT-900 will going on ebay very shortly. One might have though that in the four years since the Palm Pre came out that wireless charging would have been perfected. Regrettably, if the DT-900 is anything to go by, it has a long way to go to even match what Palm offered. YMMV.

Faster Wifi in Airplanes Coming Soon…

Posted by J Powers at 12:21 PM on May 10, 2013

wifiThanks to the FCC you might be able to finally watch your Netflix from the plane.

Due to a proposal by the Federal Communications Commission, they are looking to take over a handful of newly acquired airwaves. The new spectrum could make your in-flight Wifi experience 30 times faster than what you experience now. FCC chairman Julius Genachowski and several colleagues voted unanimously to move forward with this plan.

“The reality is that we expect and often need to be able to get online 24/7, at home, in an office, or on a plane,” said Genachowski.

Companies like gogo wireless will still be controlling in-flight Wifi and you will (for now) still have to pay a fee as you go. However, with a speed as good as a coffee shop, they expect more users pull out their smartphones and tablets to connect up and watch a movie, check email and surf the web while 30,000 feet in the air.

The new Wifi format will share 14.0-14.5 GHz of the spectrum. This will allow data transfer of up to 300 gigabits per second – shared by all aircrafts using Wifi at that moment.

 

 

LG Uses NFC to Connect Smartphones to TVs

Posted by Andrew at 7:19 PM on January 29, 2013

LG Logo

NFC has been a solution looking for a problem for some time, but products using NFC to solve real world issues are finally beginning to appear. Todd speaks with Brad from LG about how NFC is helping get video off smartphones and onto TVs.

Most people wanting to show video from their smartphone on their TV would automatically reach for a cable and then probably spend the next 10 minutes hunting around for the adaptor to plug the TV’s HDMI cable into the phone’s much smaller socket. NFC eliminates all this by wirelessly providing the information needed to stream the video to the TV using Miracast and all the person has to do is place his or her smartphone on the NFC tag. It’s not limited to sending video to the TV from the smartphone as the reverse is also possible: they can view what’s on the smart TV on their smartphone. Watch the video to see it in action – it’s very cool.

D-Link Cloud Cameras and Routers at CES

Posted by Andrew at 2:00 AM on January 7, 2013

D-Link LogoD-Link announced at CES today a range of IP cameras and routers with cloud connectivity for remote monitoring and viewing.

The two new cameras are the Cloud Camera 1050 (DCS-931L) and Cloud Camera 1150 (DCS-933L) which come with remote monitoring as standard via mydlink and mobile devices, but also offer new capabilities such as audio detection with image alerts based on sound, not just motion, and an integrated wireless repeater mode for expanded coverage that eliminates wi-fi dead zones and lets consumers easily add more Cloud Cameras without worrying about existing wireless coverage. That’s a pretty clever idea, building a repeater into the camera. Of course, these are 802.11ac devices and the 1150 also offers infra-red illumination for night operation.

 

DCS-931L CameraDCS-933L Camera
To go with the IP cameras, D-Link’s new 11ac routers are the wireless AC1750 Dual-Band Gigabit Cloud Router and Wireless AC1200 Dual-Band Gigabit Cloud Router (aka DIR-860L and DIR-868L) which deliver speeds of up to 1750 Mb/s and 1200 Mb/s respectively by combining both 11ac and 11n technologies. In addition, both Cloud Routers offer easy remote network management with the free mydlink Lite app from an iPhone, iPad or Android device, which is interesting and could be useful in a number of environments.

Catering directly to today’s increasingly mobile lifestyles, D-Link’s new Cloud Cameras and Cloud Routers offer the latest features and performance available for home network and monitoring needs,” said Daniel Kelley, Associate Vice President of Marketing, D-Link. “Keeping an eye on loved ones and valued possessions is easier than ever with greater Wi-Fi coverage and higher quality viewing and recording day and night. And, the new 11ac Cloud Routers give today’s connected homes with multiple user and high-bandwidth activities the ultimate in network performance and remote management capabilities.

The cameras and routers will be available in the next few months – The Cloud Cameras 1050 and 1150 will be available in February for $79.99 and $99.99 respectively. The dual-band gigabit Cloud Routers DIR-860L and DIR-868L will be later in April for $149.99 and $169.99.
