Wireless Internet

Wifi & Your Data Plan

Wifi Your Data PlanI recently acquired an IPOD Touch. I am amazed just how many WiFi sites that are available and are free to access! In case you are not aware an Ipod Touch can pretty much do everything an iPhone can do. Except make phone calls on the cellular networks provided by the phone companies. This is how you Wifi Your Data Plan.

They can connect via WiFi and browse the internet, do your email, Facebook and a thousand other applications, same as the iPhone. If you really want to make phone calls, you can use Skype to make calls. They are free when it is a computer to computer call and you pay a nominal fee when the calls are made to non Skype users.

What is really neat is that all of this data, phone calls, email , net surfing , Youtube videos etc is free as long as you are using a WiFi connection. Wifi Your Data Plan and save thousands of dollars.

This is the real advantage of an iPod Touch and as it turns out any smart phone that can also use WiFi. I also have an iPhone from work which does all of the things an iPhone is supposed to do over the cellular voice and data network. It is a 3G model so it is one of the later ones so it has all of the features that you need in a smart phone. I especially like the touch screen and large size that you have to work with viewing emails and web sites.  It is much more intuitive to use although it does have several limitations.

Major Advantage

For example, you cannot connect other devices other than ear phones, and there is no USB interface. Even without that it is a great little tool to use and I much prefer it to a BlackBerry device.

The real advantage of the iPhone in my mind is that you can program it to take advantage of free WiFi connections when there is a WiFi network around. It will use this free network instead of using the carriers data network and costing you a bundle for all of the data you are downloading.

Movies take a lot of data transfer and you can use up your plan quickly, and then are forced to pay very expensive rates for all of the extra gigabits of data that you download.

I do not know if other smart phones do this as well. I hope so. Maybe anyone reading this blog can let us know if this can be done by other smart phones. Most offices now have their own wifi networks.

Of course they are password protected, however if you have an iPhone provided by your place of work, or you have your own, you can sign into the network and use the free WiFi instead of using up your data plan.

Wifi Your Data Plan – Starbucks Announces Free WiFi

If you do not already know this, many coffee shops offer free WiFi to entice their customers to come in and stay awhile. Starbucks had this crazy scheme were you had to have a Starbucks card. Also have a balance of at least $5 on the card. If you maintain this balance you can have 2 hours of free WiFi every day. However you have to log in to your account to be authenticated.

Starting in July, apparently, WiFi will be free and unlimited as well to compete with the other coffee shops in the area. So program your iPhone to take advantage of these free sites. For most sites all you need to do is log in once. The iPhone will remember this for as long as you own the phone.

This is an absolutely great way to minimize your data bill with your carrier. Also you can use skype at these locations to make free calls to other Skype users. More savings for the user!

Other locations Offering Free WiFi

McDonald’s across the US offer free WiFi. They have not copied this in Canada as of yet. Many coffee shops offer free WiFi, including Second Cup, Bridgehead, non chain shops and lots of small mom and pop shops also offer free WiFi. The major chain in Canada that currently does NOT offer free WiFi is Tim Hortons.

I guess they feel that they have a large enough client base that they do not need to offer WiFi at their donuts shops. As of Sept 2012, they began rolling out WiFi to their donut shops.

Wifi Your Data Plan – WiFi at Home

Add a wireless modem at home and you can use your iPhone to browse the internet and any other apps you might want to enjoy. Make sure your home WiFi is password protected. Program your iPhone or iPod Touch to access this connection for surfing and playing games etc.

WiFi at home also makes it much more convenient for your users with laptops or other wireless devices. Most cable and dsl providers now offer WiFi enabled modems to enhance their customers experience and convenience. Installation is easy and from the first moment you can connect all of your computers as well as iPhones and iPod Touch devices with no problems whatever.

They also come with standard Ethernet ports to allow direct wire connections for older computers. Or those of us who want to have a more secure connection. This is convenience at the utmost and it saves you money at the same time over your wireless data plan.

If you have other thoughts about using WiFi instead of your wireless data plan on your data phone or smart phone. Please feel free to leave your comments and thoughts as part of this blog. We can all use more ideas to save us money, find new applications and enable the phones we have to be better tools for us.

Five Problems with Cell Phone Networks

Five Problems with Cell Phone NetworksMany people do not have any appreciation for just how complex the Cell Phone Networks are and how easily congestion can delay or prevent calls going through the network. There are many locations within the network that can act as choke points. The engineers at these communications companies are always monitoring and improving this network. However it does take time to update these networks. Frankly if a given area does not have enough potential to drive revenue, the carriers will not invest a lot of money into these poor service areas.

There are 5 main areas that these choke points can be lumped into. We will discuss them in a moment. However when you add data calls, the amount of traffic increases exponentially and places additional strain on the network. In fact data is growing at a higher rate than voice traffic. This is becoming a challenge to many cell phone companies since they need to spend millions of dollars to fix some of these data choke points to deal with the exponential growth in traffic.

The 5 areas are: A) Airwaves B) Buildings C) Switching Gear D) Land Lines E) Application Servers. A data bit travels from your cell phone via airwaves, through building walls to cell towers, then via land lines to switching , more land lines to applications servers which will process the data bits and deliver back to you the information you requested. There are ample opportunities for the data bits to be slowed or delayed while each device deals with the traffic that is being sent to it. As traffic increases this only gets worse unless additional capacity is added.

Cell Phone Networks Problems


Congested airwaves are less problematic than other choke points, but they still slow service.

Take the fastest 3G network today, which can support a download speed of 21 mega bits per second. Someone using a laptop wireless card that also supports 21mbps can surf the web at full speed.

But if two laptop users try to download at 21mbps from the same cell tower, the highest speed each consumer will see is cut in half. If a third user tries to download at the highest speed, divide the peak speed by three, and so on.

Fortunately not every laptop needs or can deal with 21 mbps, but you get the point when you have a congested site that has thousands of cell phones, or wireless cards competing for limited resources the response time can become delayed.


City skyscrapers block wireless signals, and office workers using cell phones at their desks clog networks originally designed for people on the go.

These same buildings can attenuate a signal so much that a cell phone can work perfectly fine outside and not at all inside. Weaker signals slow the transmission of data  and use your batteries power much faster.

Switching Gear

Applications like Yahoo Messenger that constantly send and receive signals on the network play havoc with switches, which were built for sustained calls. A two-minute IM chat can require as many signals as it takes for 10 voice calls. A single computer with an air card can be running 4 or 5 applications at the same time, generating data traffic from each of the applications aimed at different servers in the network.

Signaling traffic is growing 50% faster than data as more apps are constantly “on,” according to Signals Research Group. That’s in part why iPhones generate more traffic than 30 basic cellphones.


Data bits flow from cell towers through fiber and copper lines to a switching station. Then from the switching station again via land lines to application servers via even more switching stations. Data and calls are then sent to their final destinations over even more landlines and servers.

The scheme, designed pre-smartphone, can push only 75% of a tower’s maximum capacity to the next switch or endpoint. Wireless data is expected to more than double annually from 2008 to 2013. Video and apps will grow more popular, landlines are a growing problem.

Application Servers

Many of the tens of thousands of applications for smartphones connect to the public Internet through their own servers. So don’t always blame the wireless carriers for bad service. Slow loading corporate e-mail or sports scores can be the fault of an app maker’s own bandwidth constraint.

It does not matter whether it is ITunes, CNN or any other site that is receiving lots of traffic from all over the world. The application servers must receive the data, process it, and determine what information is being asked for. Once they ind it, queue it for transmission and then send it back to the original requester there are many obstacles.  And this is the simple straight forward version.

Applications servers can be their own choke point if many users are making the same request at the same time. This occurs routinely when something is advertised on a web site or on TV and thousands of people make the same request at the same time for information about the same subject.

Cell Phone Networks – Summary

With all of these possible choke points in the network it is amazing that the communications system works as well as it does. Rest assured that data engineers are monitoring and making adjustments routinely every day. They improve the network and adding capacity to deal with an ever increasing traffic demand. Especially as more and more smart phones are added by customers across the country.

Skype as a Solution to Indoor Coverage

skypeThose of you who are not familiar with Skype should really have a look at this application. This post is about how Skype can help you when you have a weak wireless signal in your home. However there are many more benefits to Skype than this specific application we will look at during this post. Many people are using high speed internet in their homes. More and more are also connecting a wireless router to the high speed modem supplied by the cable company or the telephone company. This way they can connect to the internet from their PC’s from anywhere in the home. They do not need to have wires running around everywhere. This is by far the best way to use the internet and the most convenient for the family. Just make sure that you are properly password protected with a strong secure password.

A Solution to Indoor Coverage

Skype is an application that you download onto your PC and use as a VOIP phone on your PC. It works great as long as you have a connection to the internet and a PC to run the application. You can make calls all over the world to other Skype users as well as to any cellular and land based phone.

While you may have excellent wireless coverage from your wireless router for connection to the internet, you may have really poor coverage from your cellular phone because the cellular signal is either too weak or cannot penetrate the walls of your home. You may find that you are dropping calls in the middle of a call or cannot even initiate a call with your cellular phone.

Now this is were Skype comes in, providing that you have a smart phone that can access the internet via your wireless router. I know for a fact that an Apple Ipod touch can do this because I do this every day, however not all phones can connect via WiFi due to restraints or controls that the telephone companies place on their phones.

The trick here is to be able to download and install Skype on your smart phone, establish a Skype account and then use Skype instead of the cellular service to make your phone calls. If you can do this you are away to the races, since not only will you be able to make good quality phone calls from your home using your cell phone, it will be much cheaper as well.

Skype to Skype Calls are Free

If you pay as you go, Skype calls to other Skype users are free. If you make calls to regular phones Skype charges around 2 cents per minute for many calls. Some are more, but way cheaper than any cell phone.

Alternatively you can also arrange to have Skype phones installed in your home. So that they always use Skype when you are making calls. If you follow this example, you may want to purchase a calling plan. For example the $3.00 a month plan for free monthly calling across North America.

You can also purchase a telephone number that people can call and it will find you anywhere you are when you are connected to the internet. Voice mail can also answer when you are not available. so how does this all work into a solution for poor indoor coverage at home.

Once you have Skype installed and working, forward your cell phone calls to your Skype number and answer all of your calls on your Skype phones. When you leave, remove the call forwarding and use your cell phone as you would normally. If your phone has the capability to download applications use your cellular phone with the Skype application activated while you are at home so you never miss a call again or drop calls while carrying on a conversation.

The Ipod touch is a perfect example of how anyone can use a smart computer as a phone. Once you download Skype from the iTunes store for free, install it and you are ready to go. There are many free WiFi sites around which you can use to make phone calls. Your home can become a free wi-fi site or you can password restrict it with a password. Either way you can make phones calls from your smart phone as soon as you connect.

If anyone knows of other approaches for fixing poor indoor coverage, please leave your comments to this blog. For more wireless internet details and info, click here.


Wireless Router Basics for the Home

Wireless Router Basics This post is about Wireless Router Basics. Home owners who have high speed cable or DSL systems installed at home can download email, browse web sites and even listen to music and videos once they have high speed access to the internet. Often they will connect their computers directly to the cable modem via the Ethernet connection. There is nothing wrong with this approach as long as there is only one computer to access this high speed connection. If you want to connect more than one computer then you need to purchase what is known as a router. It allows more than one connection from multiple devices.

Wireless Router Basics

Think of a router as a device that will route and manage traffic such that traffic destined for one computer will always go to that computer and traffic destined for the other computer will always go to the other computer. It is a traffic cop such that one computer cannot hog all of the capacity. It also prevents unwanted visitors from getting through the router to your computer.  Most small home routers can support connection of up to 4 hardwired computers, however this requires the use of connecting cables to run from the router to an Ethernet card on each computer. This is really a problem for a lot of families who want to have multiple computers spread throughout the home. Cables are unsightly and most homeowners do not want to have anything to do with them.

Fortunately there are wireless routers that will support multiple computers up to a reasonable distance. All you need to have is a wireless Ethernet card in your computer and you can connect with the router and hence the internet.There are the basics you need to know before getting a wireless router for your home network, as well as Network World’s tester’s top pick.

Wireless Routers

Wireless routers have come a long way in a short time. The oldest standard wireless LAN technologies follow the IEEE 802.11a and 802.11b standards, which were established in 1999. The 802.11a standard uses the 5 GHz frequency and has a maximum data rate of 54Mbps. The 802.11b standard uses the 2.4 GHz band and delivers a data rate of 11Mbps. The upshot of this is make sure you purchase a router that supports 54Mbps of throughput for the data rate.

Note that with all wireless routers, the actual speed you get over the airwaves varies greatly based on distance and other factors like the types of obstacles that lie between your computer and the wireless router that cause interference. The rates given here are really just theoretical maximums. New standards are being introduced which will see routers that support up to 150Mbps to 300Mbps.

The 802.11n technology started showing up in many wireless routers in 2008, before the standard was even ratified. But the meat of the standard was there at the time, and manufacturers did not have to do much to update their wireless routers to comply with the standard once it was finalized. With a higher speed router there is less chance that your home network will become the choke point if one computer is generating a lot of data traffic.

Wireless router security

With the rapid deployment of broadband Internet access across the country and the world, the deployment of wireless routers shot up, too. This raised all sorts of security concerns, because wireless traffic is vulnerable to snooping.

Use of WPA2 is recommended for wireless routers in the networks of both homes and businesses. Most people protect their routers by applying a password. This stops anyone who is trying to access the wireless signal. A few people will leave their routers open. Anyone can use their service, leaving them open to paying for traffic that they are not personally aware of. They are exposed to downloading material that would be considered questionable. It also leaves them open to penetration of their computers as well.  Always apply a password. Only give it out to people who you want to use your high speed access.

Where to Buy

Today’s wireless routers are manufactured by companies including 3Com (which is being acquired by HP). Also  Belkin, Buffalo Technology, D-Link, Linksys (owned by Cisco), Netgear, and others. They are sold in stores such as Best Buy, Staples and a host of other electronic stores around the country.  Experts and any of these stores will be happy to walk you through the steps of setting up your router, although the instructions are pretty straightforward and simple to use.

Once installed and with each of your computers equipped with a wireless Ethernet card, you will be able to enjoy the flexibility of using your computer in any room of the house or even the back yard.

Wireless Internet @ Home

Wireless InternetMost homes are not equipped with Ethernet cabling throughout the house. This is the type of cabling you need to connect your computer to your cable modem or to your DSL modem. In some cases consumers will also have a small router. They can connect to their high speed modem which will support up to four computers and a network printer. Running cables to 4 different computers and a printer spread throughout a house is a non starter for most people. They just do not want to clutter up their homes with all this cable laying along the floor.

Wireless Internet via WiFi

There is another solution and that is adding wireless internet to your home using a wireless router. These devices are relatively inexpensive and also easy to install. You will need to have a wireless card in each computer that you want to connect to the router over a wireless connection. If you have printers with a wireless card you can also connect the printer to the wireless network allowing all computers to print from this network printer. The printer can also be connected to one of the computers or to the router via an Ethernet card.  Most wireless routers will also support several wired connections as well.

Coverage with a Wireless Router

With a wireless router, wireless internet @ home can be very convenient. the kids can connect their computers from anywhere in the house, the parents from the den or while watching TV.  Basically anywhere in the home as well as within a short distance from the home outside. Even some of your neighbors may be able to access your wireless network from their homes if your wireless router is located properly.

A precaution that everyone should follow when they install wireless router is to password protect it to avoid unwanted people from accessing your network and using your service for free. The best case is that they will use your network for free and drive your traffic up to a point were your service provider decides that they need to charge you a higher fee. The worst case is that they download large files of questionable material or worse hack into your own computers and take a look around at your personal files. Right now out of four wireless networks that I can see, one is wide open and accessible. Always protect your wireless network with a password.

Sometimes when I am waiting for my wife to finish an appointment at the hospital, I drive into the nearby neighborhood and look for an open WiFi that I can use to read my mail and browse the internet. I usually have no problem finding one. Password protect your WiFi to stop people like me from using your WiFi for free.

Setting up Wireless Internet

Setting up wireless internet at home is pretty straight forward. Turn off your high speed modem, plug the Ethernet cable provided with your wireless router into the high speed modem and the wireless router. Plug both units in and turn on both units. Insert the CD that came with your wireless router and follow the instructions. Note you need to have a wireless modem installed in your computer and turned on for your wireless connection to work.

You will be prompted to add your name, password etc and then you should be ready to connect. Provide the password to other users in your home. This is actually the network key and is needed by everyone who will access your router.

Improving Productivity with Wireless Internet

Once you are connected you can move around the house or the office with your computer and always remain connected. Read your email, chat with other users and social networks, print using your wireless router, connect multiple computers, stream music or video. With all of these advantages you will wonder why you never moved to a wireless network sooner.

An additional advantage is that when you have visitors or the kids come home they can easily connect to the internet via your wireless router without having to dig out a cable or unhook your own.  Guests can even connect from the comfort of their room without needing a cable to connect.

Router Capacity for Wireless Internet @ Home

Routers come in various capacities in terms of being able to support multiple computers as well as maximum throughput. Before you decide on a wireless router , evaluate your needs and then decide on a router.

What is the speed of your cable connection or DSL connection? Will the router utilize this maximum capacity? What content will you be downloading from the internet? Will you just be doing email and internet browsing? Or will you be downloading movies and songs which take more bandwidth? Select the router that will give you the capacity that you need. Remember that other  members of the family may be using the internet for other applications so check with them before you make a decision.

Location of our Router for Maximum Coverage

Select a practical location for the router that is easy to install and near where your high speed modem is located. If the router is located in the basement, there is a possibility that you will not have the best performance if you and your computer are on the top floor. Best location for a wireless router is in the middle of the house on the main floor, away from walls and other metallic obstructions. This is not always practical so try to locate your wireless router as close to the above suggestions to maximize your coverage and avoid poor performance.

Conversely , if you locate the router on the 2nd floor and your office is in the basement you could also have poor connection and poor service as a result.

Computer Security for Wireless Networks

In addition to setting up security on your wireless router, you should also set up appropriate security on your computer. This is like a 2nd line of defense. Protect your computer from viruses and hack attacks. Install a virus checking program. Close ports that are not needed. Set up your firewall on your computer as well as on your wireless router to maximize your security.
