802.11ac Support Now in Eye P.A.!

Why do we love working with wireless so much? Because it’s always fresh and new and never a dull moment. What’s really cool about 802.11ac–the latest Wi-Fi spec–is that it allows for some pretty damn quick data rates. With the help of extra-wide channels and 256-QAM (among other specs), the theoretical max rate ratchets up all the way to 1Gbps, without having to go all crazy with multiple spatial streams.

RF and Other Factors Still Run the Show

Just because we have potential data rates that are higher than ever, it’s still Wi-Fi and is definitely not magic. All the old rules still apply–and in fact perhaps take on magnified importance.

There are benefits to be gained by making the switch to 802.11ac. However, proper WLAN configuration, RF planning, and spectrum management still make the biggest difference between “meh” and amazing. You gotta get the fundamentals right if you want great Wi-Fi.

Eye P.A. is ready for the next big thing in Wi-Fi

With the latest update to Eye P.A., packet captures with 802.11ac data rates are handled just as smoothly as the others.

Effective Data Rate: 433.3 Mbps. Pretty fast!

Another new feature in Eye P.A. is the inclusion of a bar chart that breaks down the percentage of traffic at each of the data rates in your capture. This chart lets you see at a glance if a majority of devices on your network are achieving the speeds they should.

 

Most of the traffic in this capture was sent at 433.3 Mbps.

As 802.11ac deployments start to really gain steam, it will become more and more important for you to be able to confirm and prove that your network is working as well as you think it should be. Stay ahead of the curve. Check out Eye P.A. today!

Chanalyzer 5 802.11ac Update


802.11ac is all the buzz right now in the Wi-Fi world thanks to the very fast data rates it can achieve, as well as other cool advancements. And, its rate of adoption is expected to be much quicker than what was seen with 802.11n five years ago. Currently, consumer and enterprise AP makers are cranking out new models, and client devices are popping up like crazy in the form of MacBooks, Android phones and tablets and a whole host of other stuff. Perhaps you’re already using it, and ultimately we all will be.

So What’s Different When Dealing With .11ac?

Signals from .11ac APs can have extra-wide RF footprints. That’s right. 80 MHz-wide, and in the near future 160 MHz-wide signals, as opposed to 11n’s 20/40 MHz widths. This, along with other cool stuff is how 802.11ac cranks up the speed so high. More channel width = a bigger “pipe” to shove data through. This ultimately means less 5 GHz spectrum to go around for uncongested channels.

When you’re setting up and maintaining 802.11ac networks, you’ll need to be especially mindful of your wireless environment to realize and achieve the new higher speeds that are possible. This is because ac will not actually “kick on” to the fast 80 or 160 MHz bandwidth if it detects Wi-Fi congestion on its “bonded” channel(s). If you want the high speeds, you have to find and keep open the entire bonded channel as much as possible. Again, all this adds up to less 5 GHz bandwidth to go around. As 802.11ac adoption heats up and becomes more prolific, there will plainly be less spectrum space for these wide networks to operate with out congestion from other WLANs.

Chanalyzer Now Displays 802.11ac Info

Chanalyzer now displays 802.11ac network information along side the a/n networks in your 5 GHz wireless environment. It will show you exactly which parts of the band are being taken up by surrounding WLANs, giving you the visibility you need to choose the optimum channel, mitigate congestion and get the best possible .11ac data rates.

80 MHz-wide .11ac Overlay


Since any 5 GHz Wi-Fi NIC can detect 802.11ac beacons, you don’t even need to have an .11ac card to get this info in Chanalyzer. Just use your dual-band .11n card you’ve already got.

Dead Spots and Slow Zones

Many users of Wi-Fi experience poor connectivity and slow speeds. In one room it doesn’t work at all, and in another the speeds may crawl. To achieve a dependable wireless connection, Wi-Fi has to overcome many barriers and obstacles – some of which can’t be fixed by purchasing a newer wireless router.

Diminishing Signal Strength:

A high signal strength measurement is quite often a good indicator that the Wi-Fi connection will be fast and reliable instead of slow and intermittent. We can compare this to hearing other people talk– in a quiet, open area, you can hear someone’s voice fairly well. On the other hand, in a building with thick walls, listening becomes increasingly more difficult. The same is true for indoor Wi-Fi. As distance increases, the wireless signal strength decreases, and different types of walls and other obstructions will further impede the signal strength

Wi-Fi Signal Strength Loss From Indoor Walls

Wi-Fi Signal Strength Loss From Indoor Walls

Free Space Path Loss With No Attenuation from Walls

Free Space Path Loss With No Attenuation from Walls

This example shows what Wi-Fi signal strength would look like with and without building walls. The red colors represent a signal strength too low for good Wi-Fi connectivity.

Use the following guidelines to gauge how different materials in your home affect the signal strength of Wi-Fi. Keep in mind that a 3 dBm drop is equivalent to a 50% reduction in power!

  • Dry Wall: 3 dB
  • Hollow Wood Door: 4 dB
  • Brick Walls: 6 dB
  • Concrete: 8 dB
  • Refrigerator: 19 dB

What To Do:

Changing the location of a wireless router can improve the speed and connectivity for most users. You should try to put the wireless router in a more centralized location.

Take that Wireless Router out of the cabinet in the laundry room and find the right spot for it!

  1. Decide which rooms need Wi-Fi the most and measure their signal strength using inSSIDer for Home
  2. To improve the signal strength for every room, find a central location for the wireless router with as few brick walls and metal objects in the way as possible.
  3. Verify you’re getting higher signal strength with inSSIDer for Home.

Slow Zones from Competing Networks

Slow connectivity in an area can be caused by competing networks on the same or overlapping channel. When a Wi-Fi channel has a lot of active users on several networks, the speeds decrease for everyone. Unfortunately, the channel doesn’t belong to just you, and you can’t stop other networks from using it.

Your best option is to use a channel with no overlapping networks or share a channel that has networks with low signal strength. There are two types of Wi-Fi interference that can slow you down:

Co-Channel Interference – Networks sharing a channel cooperate and take turns talking. Channel bandwidth is shared between every Wi-Fi device.

Overlapping Interference – Networks on non-standard or overlapping channels are unable to cooperate, and will cause interference on neighboring networks. They share bandwidth with networks on standard channels.

Network Strength compared to Co-Channel and Overlapping Interference

Network Strength compared to Co-Channel and Overlapping Interference

inSSIDer for Home’s algorithm only measures the signal strength of a single wireless router and assumes each competing network is equally active. (For more accurate interference assessments, you will need to use more advanced tools like Spectrum and Packet Analyzers).

To avoid Wi-Fi slowness, find a channel that has the least amount of co-channel and overlapping interference. That means you want the fewest networks to be on your channel – and if they are, you want them to be relatively quiet (lower signal strength).

What To Do:

This exercise assumes you have already found an ideal central location for your wireless network. It also requires you to know how to configure and change the channel of your wireless router. If you do not know how, please consult your user manual.

inSSIDer for Home will display a link score for your network, which is a number that accounts for signal strength as well as the level of co-channel and overlapping interference. The Link Score is an estimation, and it assumes that each network is equally active.

Follow these steps to find the best channel:

  1. Use inSSIDer for Home to measure the link score in each room.
  2. Try channel 1, then 6 and 11 of your wireless router
  3. Measure the link score in each room.
  4. Choose the channel with the best aggregate link score for each room.

Dead Spots from Non-Wi-Fi devices

Sometimes you may have excellent signal strength, but little to no connectivity. These dead spots can be caused by competing wireless devices that use the same frequencies as Wi-Fi, but do not cooperate with Wi-Fi. Here are a few common devices that cause dead spots in the home:

  • Cordless Phones
  • Baby Monitors
  • Wireless Audio Systems
  • Nanny Cams
  • Microwave Ovens
  • Wireless Security Systems

Interference from Non-Wi-Fi Transmitters as displayed by a Wi-Spy Spectrum Analyzer

Many wireless devices have an auto-channel selection algorithm in order to provide a better connection, but this can cause more headaches than it solves. Auto channel selection is blind to non-Wi-Fi sources, and makes its selection only on the number of interfering networks sharing the same channel. It may also put your wireless network on a non-standard channel, which introduces even more interference from multiple sources. In the end, auto channel selection does not solve any problems. If anything, it makes the problem more intermittent and extremely difficult to troubleshoot.

What To Do:

Without a Spectrum Analyzer it is difficult to definitively conclude anything regarding non-wi-fi interference. Learn more about Spectrum Analysis.

The following steps will help you systematically test other wireless devices for Wi-Fi interference:

  1. Download TamoSoft Throughput Test Utility, and install it on two computers
  2. Set up the first computer as a Server, and the second as a Client
  3. Begin the Test
  4. Turn on and use the non-Wi-Fi device in question to see if it affects the performance.
  5. Restart the wireless device to see if it changed its channel. Try this a few times, until you have determined whether or not your Wi-Fi is affected by the device.

The More You Know

Slow zones and dead spots can occur for a variety of reasons. You can avoid these pitfalls by moving your wireless router to a central location and choosing a better channel, which we’ve learned about this this lesson.

Utilizing proper Wi-Fi knowledge and troubleshooting tools as you build out into the future will ensure you are able to identify what may be the root cause of poor Wi-Fi performance. Stay tuned for our next Wi-Fi Tips and Tricks update!

inSSIDer for Home Available Now!

If you have a wireless network in your house, you’ve probably experienced issues with your Wi-Fi’s performance at one time or another. The first step you can take towards fixing these problems is to look at how your signal strength and channel choices compare to the other networks around you. With inSSIDer for Home, you can do both.

network details pane includes a link score

One of the main features of inSSIDer for Home is the Link Score. This score is determined by looking at your signal strength, overlapping networks, and the number of SSIDs that share your channel. The higher your Link Score, the better your performance will be. You may have a totally different Link Score from one end of the house to the other, so make sure you walk around all of the areas you expect there to be Wi-Fi coverage.

new channel coloring scheme

inSSIDer for Home allows you to “star” your network. This will pin your network details to the right side of the screen, making tracking easier. The network colors in inSSIDer will change, making it easy to see the networks that share or overlap your channel. You’ll also see customized channel and security alerts, if inSSIDer notices you’re using settings that aren’t the best they could be.

network filtering

The filtering capabilities of inSSIDer for Home have been revamped as well! Filters are great for helping you track down potentially rogue access points (using filtering by Vendor) or checking for non-standard channel usage (by entering “2-5,7-10” in the Channels filter). From the first letter you type into the “SSID or Vendor” box, you’ll be presented with an auto-populated list of matches. This makes finding the networks you’re interested in even faster. You can also filter by signal strength, choosing to display either networks either above or below your supplied value.

inSSIDer for Home provides you with the foundation you need to make sure your personal Wi-Fi network is working as well as it can. Download inSSIDer for Home today, and let us know what you think!

Stress Testing 30 iPads in a Classroom

APstotest

Recently, Wireless Lan Professionals performed a Wi-Fi stress test aimed at proving how well Wi-Fi vendors can handle a K-12 classroom full of iPads. The Wi-Fi stress test did not compare software features offered by the various Wi-Fi access point vendors – it was strictly a test of how they utilize a single access point to send video to 30 or more iPads.

MetaGeek’s tools helped visualize the density of the wireless traffic during the testing. Chanalyzer Pro helped measure the channel saturation in the 2.4 GHz and 5 GHz. Eye P.A. measured the efficiency of the network by counting the retransmits and calculating the air time used.

Spectrum Bandwidth.

The time where a 2.4 GHz-only solution is sufficient has come and gone. Dual Band access points can relieve 2.4 GHz congestion by steering 5 GHz capable devices into a different band. When implemented correctly, band steering can improve the speeds for all connected devices.

During the Wi-Fi stress test, spectrum analysis measurements of the channels helped gauge how much traffic should be allocated to each band. For example, if the channel in the 2.4 GHz had existing Wi-Fi traffic, more iPads would be steered to the 5 GHz. Fortunately, both channels were equally free. To get the most out of the channels, a 50% distribution to channels 11 and 36 would yield the best results.

utilization

However, the Wi-Fi stress test proved that some access points prefer the 5 GHz over the 2.4 GHz. This means that they steered all of the 5 GHz compatible equipment to channel 36 leaving the 2.4 GHz unused. This caused the iPads to experience more failures earlier in the test than expected.

Uneven Band Steering (10 iPads Max) Uniform Band Steering (25 iPads Max)
5 GHz saturation 24 bad

5 GHz Saturation.

uniform 5 ghz saturation

5 GHz Saturation.

2.4 ghz bad

2.4 GHz Unused.

uniform 24 ghz saturation

2.4 GHz GHz Saturation.

Don’t assume the 2.4 GHz is useless without measuring it with a spectrum analyzer. A spectrum analyzer can help you gauge how much air time is still available on the channel when you make a band steering decision.

AirTime Fairness

After the iPads ‘picked’ their channel during the Wi-Fi Stress Test, their conversations were captured using MetaGeek’s Eye P.A. software to measure the air time efficiency. Every Wi-Fi device negotiates the speed at which its conversations are transmitted at. Devices that are far away from the access point will talk slower and repeat themselves more often. Think of a college classroom full of students having to listen to a first grader’s show and tell in its entirety – twice. The first grader talks at a very basic level and prevents the rest of the class from speaking at a rate suitable to their needs. The trick here is to have all of the Wi-Fi devices using modern 802.11n technology and disabling legacy data rates in the WLAN. This frees up a significant amount of air time for more iPads.

To measure air time allocation between iPads you can use a packet analyzer like Eye P.A. This software builds a TreePie to represent the disproportionate amount time some devices may use on the channel.

airtime fairness

Devices with high retransmission levels can definitely eat up more air time. Retransmissions occur when the original sender does not hear an acknowledgement and repeats the original transmission. This adversely affects network performance because it can double or triple the amount of airtime necessary to send a single frame. High retransmissions were the downfall of a few vendors as we saw in the packet analysis software.

Improving WLAN Efficiency

Some of the Vendors tweaked their settings before the test to improve their overall performance. If you deploy wireless networks for dense environments similar to a classroom full of iPads these tricks might benefit you.

Higher Minimum Data Rates for Wi-Fi Overhead.

Since the environment was comprised of 802.11n compatible iPads, there was no need to support legacy data rates such as 1, 2, 5.5 or 11Mbps. Since many Wi-Fi access points default to legacy compatibility these rates needed to be disabled.

40 MHz Wide Channels in 5 GHz band.

iPads streaming video build a buffer incrementally. When an access point can finish transmissions quicker it leaves more air time available for other iPads. Wider channels help the iPads get on and off the channel quicker. Keep in mind that only the iPad 4 supports 40 MHz wide channels.

Try out the new inSSIDer3 Preview Release.

Many of you may not know the history of inSSIDer and how it came to be created. Work on inSSIDer began back in 2007 when MetaGeek was still a tiny company of four people, and we had just created Wi-Spy 2.4x.

Netstumbler was still the most popular Wi-Fi scanner, but the developer hadn’t worked on it since 2005, so it had issues on 64-bit Windows XP and on Windows Vista. At that time Chanalyzer only showed spectrum data, no Wi-Fi information at all, which meant you had to use a separate tool to get a list of Wi-Fi networks while troubleshooting with Wi-Spy, and with Netstumbler development stopped, this was starting to become a problem for our customers.

We decided to build Wi-Fi scanning into our Chanalyzer software, so that it would show RF spectrum data from Wi-Spy *and* list all of the nearby Wi-Fi networks. Being a tiny company with a very limited marketing budget, we decided that creating a free Wi-Fi scanner to replace Netstumbler would get us more awareness than any advertising would. We built inSSIDer at the same time that we were building Wi-Fi scanning into Chanalyzer and released inSSIDer 1.0 in January 2008 (Chanalyzer didn’t get Wi-Fi scanning for another six months).

inSSIDer started getting noticed by places like Tekzilla and Network World and after 14 months it reached 100,000 downloads! Since then it has steadily gained popularity and has now been downloaded 8 million times and has almost 40,000 users every day!

The original inSSIDer design was influenced by Netstumbler, which was mainly used for wardriving. The Channels View was introduced in inSSIDer 1.1 and was heavily influenced by our Chanalyzer application. Since then some colors have changed and we’ve added GPS logging, but the overall design of inSSIDer hasn’t changed very much.

Inssider 1.0

Today about 90% of users use inSSIDer to help improve their personal home Wi-Fi. Over 80% of users identify their Wi-Fi skill level as beginner or intermediate, yet over 30% say Wi-Fi is critical and troubleshoot Wi-Fi at least monthly. Given these statistics we decided it was time to rethink inSSIDer and design it from the ground up with the goal of helping users improve their Wi-Fi quickly and easily, while providing education on Wi-Fi best practices.

Upon launching inSSIDer 3, the first thing you’ll notice is that “Customize inSSIDer” options allowing you to specify your expertise level and your location type (home, office, school). The “Learn” screen has also been streamlined to show more relevant information based on the user customizations.

The Networks Tab contains the standard Networks Table and Channels Views, and also adds a Network Details panel to the right of the table. The Network Details panel shows extra information about the selected network in the table, allowing the table to be simpler. This also provides a place to add additional information, such as showing the MCS Index for 802.11n networks (coming in a future release).

The Channels Views below the table looks similar to the Channels View in inSSIDer 2. All networks are displayed the same, regardless of which network(s) you are interested in.

In inSSIDer 3 you can now identify your network in the Network Details panel by starring it. Once a network has been starred, the colors of all the networks in the Channels View changes to highlight your network, networks on the same channel as your network, and networks that overlap your network. This provides a quick snapshot of the networks that could be conflicting with your network. Clicking the small clipboard icon in the top right corner of each panel will copy the table or image to the clipboard; this makes it easier to create a report if you are using inSSIDer for work.

 


In the Works…

Upcoming releases will include channel recommendations and security warnings, customized for each users skill level and environment.
