5 Things You Need to Know About How Your Wireless Network Impacts Your Devices

Its true. Not everyone needs to know what makes their wireless network tick. But if you are an entrepreneur or small business depending on a fast signal, learning the technology behind your network might just make sense. I made this short video to explain the flavors of WiFi, but then I realized that the subject deserves much more explanation. So I wrote the post below to fill in some of the gaps; it will hopefully simplify some of the crazy numbers I was throwing out.


To visually illustrate, Here's how MU-MIMO works:

Next, a chart to illustrate what you need to know about the 802.11 wireless standards:

So who sets these standards and who is the IEEE?

The IEEE is the acronym for the Institute of Electrical and Electronics Engineers, an association founded in 1963 devoted to the advancement and standardization in a wide range of industries.  They named the “alphabet soup” of 802.11 standards for wireless radio-wave technology; WiFi.

Band and Channels: Why does this matter?

Without going into a long tutorial on radio signals, the different communication frequencies (bands or the radio wave spectrum) are assigned by the Federal Communications Commission. For the United States, they decide which frequency ranges can be used for different technologies and by which industry (airlines, medical devices, cellular, public safety, etc.).

Currently in the US, the assigned spectrums for a wireless local network (WLAN) are in the 2.4 GHz to 5 Ghz bands. Within these frequencies there are multiple channels. In the 2.4 band, there are 14 channels (but only 11 are allowed in North America). Of these eleven, there are only 3 that do not overlap on the others: 1, 6 and 11.

When you are setting up your wireless network, or adjusting the channels as you should from time to time, you can see which channels have the highest traffic. Selecting bandwidth is usually done automatically by your router, but some, as in the case of Linksys, the bandwidth can be selected manually if you wish.

Early devices (using 802.11b or g) should use the 20 MHz bandwidth. If your devices are exclusively using the 5 GHz band, you may benefit by selecting the higher range. I recommend that you don’t monkey around with this setting unless you really know what you are doing - or tech support tells you to do it.

If you are using an 802.11ac router you will notice the box says “dual band.” This means that the router drops back to 2.4 GHz for connecting to older devices, in this case it’s recommended that you let your router make the decision automatically.

In my post on How to Boost Strong WiFi in Every Room, I show how I use an app called WiFi Analyzer to see the data traffic generated by my neighbors. Once you see which channels are most crowded with traffic, you can select the emptiest channel for your home WiFi network. This will assure better connections and less interference.

Transfer Rates: How Many bits per second?

As data transfer rates increase, there are more multiples for the speed in which data travels. They are referenced in “bit” per second. In the video I spoke of a mid-eighties 300 baud modem which transferred data at 300 Kbps. In case you’re wondering, kbps moved 125 bytes per second.

With the move to wireless, transmission sped up to megabits, written as Mbps. Mbps transfers a million bits or a thousand kilobits. Now we’re looking at Gbps speeds, moving 125,000,000 bytes per second - or more practically, 1,000 Mpbs or a million kilobits per second. The next iteration will be Terabits (Tbps) moving a thousand gigabits per second. You do the math, that’s crazy fast.

None of us live in a laboratory, and this is where the ultimate speeds are measured. Most of the “theoretical” speeds are done with mathematical equations.

Antennas? MIMO? Whaaat?!

In many routers, the antennas are internal. In others you can see (and even upgrade) the higher gain antennas. External antennas can be adjusted for optimum range (Will cover this in an upcoming post). Each antenna in the early protocols (Single Input Single Output) designated one antenna at the router to transmit and the other single antenna at your device to receive data. When multiple devices are leaching off the same singular signal, you can just imagine (and have no doubt experienced) how the speed degrades.

The newer protocols invoke MIMO (Multiple Input, Multiple Output) uses multiple antennae at the transmission point and multiple streams, thereby increasing performance significantly. The antennas can be pooled to optimize your stream. MIMO also can deliver four spatial streams of data to your devices. If your devices (laptops, tablets, gaming) do not support MIMO, you cannot get the full benefit of this technology.

Again, assuming your devices can take advantage of it, MU-MIMO (Multi user) send out separate signals (up to eight) to lock on to each device demanding a WiFi signal. Each antenna can also transmit a signal to multiple devices depending on demand. (As I said in the video, buying an inexpensive 802.11ac WiFi dongle will easily upgrade your laptop).

Remember, your network can only run as fast as the data is sent to it. In my case I receive 100Mbps from my cable provider. I can’t make the data run any faster.

How To Buy the Best Wireless Router for Your Network


Ask anyone. A strong, clear and fast Wi-Fi signal is one of the most important things to us (that is after food – but before sex – according to a new study). First world problems, I know. The connection to the internet for your office and home is critical; and these days, with the multitude of devices we connect to our router, speed is of the essence.

If you’ve read my post on boosting your Wi-Fi and you still need more, this post should answer your questions. I’m not suggesting that you break the bank, but spending more on essentials is a good idea. Your internet connection probably needs to be fast and ready for you twenty four/seven and has become an essential utility. When you chose to upgrade, consider amortizing the cost over the number of devices you're asking for a clean signal, then it won’t seem as much.

A May 2015 study from IDC found that 95% of those surveyed said they had routers with older protocols or did not know which wireless protocol they used. After you finish reading here, and upgrading your router, you will be one of the top 5%.

MU-MIMO

Previous routers boasted MIMO (multiple input and multiple output) radios through past protocols. Today’s newest use MU-MIMO (multi user, multiple input and multiple output) which provides significant performance gains. By sending simultaneous transmissions to your individual devices on the same channel of your wireless network the signal goes through without lag or buffering.  This means that the movie streamed to your TV and the video chat with your friend can each get their own Wi-Fi connection. MU-MIMO is more efficient, each user gets their own slice of airtime.

Multiple USB, eSATA, Ethernet and Gigabit Ports

Your new router should have several ports where you can connect various devices. A USB 3.0 port is the fastest current USB connection with data transfer up to 10 Gbps, so be sure you have at least one of these. You can connect digital media and hard drives to them for fast access throughout your network. They are backwards compatible with USB 2.0 devices (up to 6 Gbps), but you won’t get the advantage of the faster connection. Additional USB ports are preferable if they are eSATA.  eSATA is a powered (either 5 V or 12V) USB 2.0 hybrid USB port where you can connect additional drives or USB connected printers to your network for sharing.

Ethernet ports are also important for connecting to bridged networks or wired devices on your network. Having a Gigabit ethernet port is a plus; enabling you to hardwire your computer to a blazing fast 1000Mbps connection. (For best performance, be sure to use CAT5E or higher rated cables in these ports).

Dual Band Connectivity

In my last article on wireless, "How to Boost Strong Wi-Fi in every Room,” I explain the difference between the 2.4 Ghz and the 5 Ghz bands. Connecting appropriate devices to the bands as mentioned in the post will speed up your wireless connections and prevent unnecessary buffering.

It's also a plus, security-wise, if you have dual-band guest networks with different login credentials.

Antennas? or no antennas

Personally I think antennas make any wireless device look like they’re ready to conquer the airwaves. Many internal antennas are omni-directional (they send and receive from any direction). But does it really make a difference if you have external antennas? Many top-line newer routers feature external antennas for good reason, they are adjustable (generally straight up for one-story homes). They also connect directly with your devices (see beamforming below) and can also be removed and swapped out for more powerful, high gain antennas.
TIP: If your current devices (tablets and laptops) do not support all these high tech solutions, look for an inexpensive USB wireless adapter for your legacy devices and you will get the benefits of your new router.

Beamforming technology

The latest AC routers feature “beamforming.”  Beamforming technology enables the router to identify and connect directly with devices. It actually tracks each device, versus broadcasting in a circle equally in all directions.

High speed 802.11

You may have seen letters after the numbers 802.11 on your devices. The letters signify the protocol of the wireless technology used in your device. In a future post, I will explain the progress of wireless standards and what each brings to the user. Popular versions from the recent past have included 802.11g and 802.11n.  To get the latest in technology, look for the most current standard “AC” or 802.11ac. The AC protocol supports the fastest transfer rates currently available.

These variations have been monitored by the non-profit WiFi Alliance since 2002 to certify that wireless devices will work with other devices across brands. When you’ve narrowed your search to a few routers, you can double check their status of interoperability at their site here.

Although it is highly unlikely that you will reach maximum cleanroom speeds (as advertised on most routers' packaging), they may say they are capable of s high as 1900Mbps. More than likely, you can get pretty much expect to get what your ISP says you can get, they set the speed.

Modem

This post wouldn’t be complete unless I remind you that the fastest cable modem currently available is DOCSIS 3.0 (backwards compatible with older standards).  DOCSIS 3.0 has more channels than previous versions and can bond multiple channels for higher speeds. The typical DOCSIS 3.0 modem generally has four or eight channels for downloading and can result in a speed cap of 172Mbps or 344Mbps. For uploading, they generally support four channels up to 124 Mbps. DOCSIS 2.0 (the previous iteration) is much slower and only supports one channel up and one channel down. If you rent your modem from your internet provider, request an upgrade.

Why not print out this post and take it with you when you shop for a modem, so you won’t get confused (like I do) by the many tech catchwords you will see on the boxes.

You've Got to be "In It" to Win It Never Applied More #GoGlobal


After I graduated and got in the real world of advertising, my observances of the small business people taught me far more than a classroom ever could. There were those (no matter how great their customer service) who just couldn't make a go of it. Others succeeded in ways which were a mystery to me. Dumb luck, I guess.

But for those who achieved some modicum of success, they found their niche and were able to grow. Their business built jobs for family and others. Some expanded their enterprise to other locations and many, eventually online.

These people took a challenge and grabbed it. They worked out what they knew and studied to learn more of what they didn't. It takes a special kind of entrepreneur to succeed and build a business for a lifetime. It really made no difference whether they chose to stay small or to expand. Their accomplishment spoke volumes.

Now that anyone with a plan and some gumption has access to an international marketplace on the Internet, it brings new challenges. I would have never thought that my small, online business would be shipping product to Moscow, or Buenos Aires or Tokyo. But I have; and now service customers worldwide.

Which brings me to the point of this post. The idea of sending merchandise to customers overseas used to scare the heck out of me. I knew there were customs regulations and I knew it would be ever more expensive (even if the customer paid the shipping).  Who would even care to spend extra to buy from me?

I took the step first by selling action figures and opened up sales to a worldwide audience. Amazingly, even in the early 2000s, there were people willing to buy and pay a premium for my goods!

The first step is getting past that fear. When businesses are growing and succeeding, there always seems to be a similar barrier: expanding globally. I’ve worked with more business owners than I can count who just don’t want to go the extra mile (pun intended) and expand their markets internationally.

There are various reasons entrepreneurs hesitate before taking the global leap. For one, there’s a popular myth that shipping across borders significantly changes the status quo. Yes, no one likes change, but the logistics behind international shipping can be just as easy to navigate as domestic shipments once you know the rules.

An easy way to get your feet wet is to take a single product and start selling on an established international marketplace like eBay. For any ecommerce business, I suggest starting slowly and first deciding which products and countries blend best for your business. Read my article here for tips on how to save money while expanding your business globally.

This week I will go to IRCE (Internet Retailer Conference and Exhibition). If you ever intend on stepping into a full-blown ecommerce business, there is no better place to start (once you've read my books - of course). The sessions are most excellent sources of information.

Granted, going to the conference is quite expensive for a small business. So I recommend going for the first time to just the exhibits, where a pass is $75 (when you purchase in advance). The exhibits at IRCE cover a 250,000 square foot show floor and boast over 600 vendors showing off the latest in technologies for the new retail economy. The ideas that will come to your mind when walking the floor will be dazzling. Plenty of ROI to cover your transportation and hotel!

No doubt when you're there, you will see a badge of someone you've met online or a representative for a service you've considered using. Its the perfect place to get recommendations and network with other businesses like yourself.

I will be at IRCE 2015 sharing the experience recording videos (using Periscope too) and doing a book signing in the Pitney Bowes booth (#743) on Wednesday and Thursday.

Pitney Bowes has been around a long time, and as a forward thinking company, has some new ideas for cross-border commerce. Talk to one of the people in their booth and learn how to take the next big step in enterprise level fulfillment. They will have experts who can help you develop and execute your international growth strategy.

It's a big step from shipping First Class International packets to moving your full business online. The Pitney Bowes folks are there to hold your hand to help you succeed. Stop by the booth and say hello. Tweet me @MarshaCollier or @PB_digital during and after the show and we'll be glad to point you in the right direction.

How to Boost Strong Wi-Fi in Every Room


Is your Wi-Fi network more important than sex? Surprising data from March 2015 IDC study on home networks, sponsored by Linksys


Since the early days of computing, sharing content from place to place has been a challenge. Networks in the old days required installation by those who were expertly trained in their field. Small businesses used “sneakernet” (the process of carrying disks from one computer to the other). Now we have wireless connections and we all share. Yet in the age of this cutting edge technology, we often find ourselves waiting for that Netflix movie to stop stuttering or pixelating. Buffering is just plain annoying.

The first thing we think of, (and the most common solution) would be to purchase higher speed plan from our internet service provider. But wait before you make a sizeable ongoing investment. There’s a whole lot more that you can do on your end.
#TIP: If you haven’t spoken to your ISP in over a year, give them a call and they will probably offer you savings on your current plan with faster internet included. I just did that and doubled my speed.
Your internet connection comes in via a cable of some sort and is received by a modem. To build a wireless network, you cable the modem to a router, which broadcasts your internet thoughout your home or office. You may get a fast signal coming in, but what happens at your end can make a big difference in the quality of how the signal is delivered to your devices.

How many devices do you currently connect to the internet?

Take a moment to count them. Today we demand a lot from our networks. In my home, we have smart TVs, a gaming platform, multiple tablets and smartphones, Nest thermostats, WeMo security cameras, music streaming devices, satellite TV adapters, a weather station, wireless printers and, of course laptops. Not every device is online all the time, but it would be fair to say that we have at least 10 devices connecting to the internet at any one moment. What about at your place? Make a list and see how many device are competing for your bandwidth.

Where is your router?

Ideally you should position the router in the most central location in your home, preferably on top of a desk or (even better) on top of a bookshelf. If you have a multi-story home, its best to put your router on the 1st floor higher up in the room like on a book shelf so the wireless signal can be closer to devices on the second floor.

What is in “line of sight” of your router?

I realized that I had my router on top of a desk, but on the other side of the wall was a kitchen counter with a granite backsplash. Granite degrades a Wi-Fi signal as well as all of the pipes and appliances in the kitchen. Centrally located brick fireplaces, fish tanks (full of water), built in bookcases, hardwood furniture and even plaster walls are dense objects that cut down your signal. Older routers send the Wi-Fi signal in a single stream. As the signal reaches each device, the strength is leeched until the furthest device has a pathetically weak stream.

Why not consider a Wi-Fi Range Extender?

Very few of us live in an ideal world. My router is at the far end of a long, ranch style home. Your home may have more than one story and no doubt you have some dead zones. Because I have almost every barrier to a clear signal, I use a range extender. The best range extenders you can buy are compatible with all brands of routers (even the ones you get from a service provider). You place the range extender halfway between your router and your deadzone. It will pick up the Wi-Fi signal and increase the range. The one I am using, Linksys AC1200 Amplify, model RE6700 will extend your network up to 10,000 square feet.

Does your router support “Dual-Band” and are you taking advantage of it?

I first learned about bands when I learned about wireless phones. Their early roots were in the 2.4 GHz band but to beat interference from microwave ovens and went to 5.8 GHz then Dect 6.0. In practice, it was clear that the less crowded the band, the clearer the signal would be. Radio waves are everywhere and older routers only broadcast in that same 2. 4 GHz band.

Without going into a tutorial on radio waves, broadcast frequencies and connectivity, take my word that the 2.4 GHz band has a lot of traffic. It is crowded with cordless phones, Bluetooth devices, baby monitors, garage door openers, microwave ovens and more.

If you have a router that supports Wireless-N or AC, you have two bands: 2.4 GHz and 5 GHz. Run both at once and let your devices connect to the bands that work best for them. The range of the 5 GHz band is shorter than the 2.4, but the latest routers with this technology have a more sophisticated beamforming antenna array and MU-MIMO.

The 5 GHz has a wider wireless spectrum available compared to the 2.4 GHz, which leads to significantly better performance as the 5 GHz is best for usage that requires uninterrupted throughput. That is why it is recommended for media streaming and transferring music, pictures, and video throughout your home network.

What channel are you using?

I know, right? Wi-fi networks use channels! There are 14 available channels in the 2.4 GHz band. If you and your neighbors are using the same channel, it could degrade your signal too. There are a few ways to find out which channel has less traffic. I use an app called WiFi Analyzer (see below). The app will show you all the networks within range of your devices and recommend the best for you to use. You can also use it like I do. I open the app and walk around my house. As I walk, the graph below changes, picking up and dropping new networks as I move (no I do not live next door to a 7-Eleven). After a full walkaround of my home and office, I selected channel 11 for my network.


You can change the broadcast channels of your router from the router’s interface.

How old is your router? 

No matter how fast your ISP is pushing the internet to your home or office, you will not be able to benefit from speed if you are using old technology. New routers that feature Max-Stream MU-MIMO send out three streams, thereby allowing three devices to basically have their own dedicated high speed connection.

Many people I know are still using the router rented from their ISP, or one they purchased years ago. I remember when wireless-G was cutting edge, then Wireless-N; today it’s Wireless-AC. It’s doubtful that all your current devices support the latest versions of 802.11, but the latest technologies need more throughput as well as bandwidth. Why spend hundreds of dollars on new devices if your current router degrades their performance?

In upcoming posts, I will explain the facts behind the types of 802.11 and the things you need to know before buying a new router. If you have questions about your wireless network, please send them to me and I try to answer in a future post.

Testing New Gogo Text & Talk Service at SXSW

gogo flying lab
By Marsha Collier

Duty Calls. When an email arrives inviting you to join the likes of Bell, Edison and Marconi, you definitely need to read it. I was lucky enough to be one of the first to use Gogo’s new Text &Talk service on Gogo One, the company’s “flying test lab.”  Not only would I have that honor, but I was to be part of the first in-air BBQ food truck with incredible Texas barbecue from Keith’s BBQ of Austin.


The Gogo twin jet is a Canadair Challenger 600 flying test lab, and features their latest Air To Ground system (ATG-4), along with our business aviation system, Iridium phone service, Inmarsat Swift Broadband satellite service and the Gogo Vision entertainment system. I had to poke around and see where the magic happens. Across form the lav was a closet, filled with the latest in technology.
We were given the tail number of the plane so we could log on to Flightaware.com to track our progress as we flew at 600 miles per hour, 30,000 feet above all the revelers at #SXSW in Austin.  Alternatively, I could log on to the Glympse app, which would have allowed me to send real-time location information and estimated time of arrival with anyone while up in the sky. After sending a Glympse of your location to your earth-bound friends, you can shut down your mobile device and your friend or family member will remain updated with your location through the duration of the flight.
