What is WiMAX?




WiMAX is an IP based, wireless broadband access technology that provides performance similar to 802.11/Wi-Fi networks with the coverage and QOS (quality of service) of cellular networks. WiMAX is also an acronym meaning "Worldwide Interoperability for Microwave Access (WiMAX).

WiMAX is a wireless digital communications system, also known as IEEE 802.16, that is intended for wireless "metropolitan area networks". WiMAX can provide broadband wireless access (BWA) up to 30 miles (50 km) for fixed stations, and 3 - 10 miles (5 - 15 km) for mobile stations. In contrast, the WiFi/802.11 wireless local area network standard is limited in most cases to only 100 - 300 feet (30 - 100m).

With WiMAX, WiFi-like data rates are easily supported, but the issue of interference is lessened. WiMAX operates on both licensed and non-licensed frequencies, providing a regulated environment and viable economic model for wireless carriers.

At its heart, however, WiMAX is a standards initiative. Its purpose is to ensure that the broadband wireless radios manufactured for customer use interoperate from vendor to vendor. The primary advantages of the WiMAX standard are to enable the adoption of advanced radio features in a uniform fashion and reduce costs for all of the radios made by companies, who are part of the WiMAX Forum™ - a standards body formed to ensure interoperability via testing. The more recent Long Term Evolution (LTE) standard is a similar term describing a parallel technology to WiMAX that is being developed by vendors and carriers as a counterpoint to WiMAX.

About WiMAX Roaming

What is WiMAX Roaming?
The WiMAX Roaming White Paper provides an overview of business models and technical aspects of roaming. Roaming enables customers to automatically access their wireless services when travelling outside the geographical coverage area of their home network. This includes internet, e-mail, voice, video and other services available on the home network. Roaming provides the ability for you to access your wireless services by using the network of an operator that is not your home network operator. This is made possible by your home network operator agreeing with other operators to allow you to use your wireless services on their networks.

Benefits of WiMAX Roaming
Roaming provides significant advantages to customers and network operators. Roaming can dramatically expand the coverage area available to customers and can enable an operator to expand its footprint.

Types of Roaming
Roaming can either be national or international. National Roaming occurs when the visited network is in the same country as the home network. International or Global Roaming occurs when the visited network is in a different country than the home network. Roaming can also occur between networks using differing technologies, such as WiMAX and Wi-Fi or WiMAX and 3G. This is known as Inter-standard roaming.

Connecting Operator Networks for Roaming For roaming to occur, the networks of two operators must be connected to provide access to services and to enable the process of sharing usage information and to facilitate billing and financial settlement between operators. This can be achieved by operators establishing direct connections between their networks or by connecting their networks through a third party roaming exchange provider (WRX). One advantage of connecting through a third party provider is that this can enable an operator to connect with many other operators through a single connection. This can allow an operator to expand its footprint quickly.

Roaming Agreements
Roaming agreements set forth the terms and conditions by which operators agree to provide each other’s subscribers with access to their networks. An agreement details which services are to be provided and the rates that the operators will pay for using the other’s network. The agreement also includes information relating to QoS, customer care and billing and financial settlement.

VOIP Internet Phone and Internet Telephony FAQ

How VoIP / Internet Phone Works
VoIP converts the voice signal from your telephone into a digital signal that travels over the Internet. If you are calling a regular phone number, the signal is then converted back at the other end. Internet Voice can allow you to make a call directly from a computer. If you make a call using a phone with an adaptor, you’ll be able to dial just as you always have, and the service provider may also provide a dial tone. If your service assigns you a regular phone number, then a person can call you from his or her regular phone without using special equipment.

Background
Internet Telephony, also known as Voice over Internet Protocol (VoIP), is a technology that allows you to make telephone calls using a broadband Internet connection instead of a regular (or analog) phone line. Some services using VoIP may only allow you to call other people using the same service, but others may allow you to call anyone who has a telephone number - including local, long distance, mobile, and international numbers. Also, while some services only work over your computer or a special VoIP phone, other services allow you to use a traditional phone through an adaptor.

What Kind of Equipment Do I Need?
A broadband Internet connection is required to make VoIP calls. Some services allow you to use a regular telephone, as long as you connect it to an adaptor. Some companies allow you to make calls from a computer or a VoIP phone that doesn’t require an additional adapter. If you are calling a regular telephone number, the person you are calling does not need any special equipment, just a phone.

If I have VoIP Service, Whom Can I Call?
Depending upon your service, you might be limited only to other subscribers to the service, or you may be able to call any phone number, anywhere in the world. The call can be made to a local number, a mobile phone, a long distance, or an international number.

What Are Some Advantages of VoIP?
Because VoIP is digital, it may offer features and services that are not available with a traditional phone. If you have a broadband Internet connection, you need not maintain and pay the additional cost for a line just to make telephone calls.

Does My Computer Have to be Turned On?
Not if you are making calls with a phone and adaptor or special VoIP internet phone, but your broadband Internet connection needs to be active. You can also use your computer while talking on the phone.

Is There a Difference Between Making a Local Call and a Long Distance Call?
Some VoIP internet telephony providers offer their service for free, normally only for calls to other subscribers to the service. Some VoIP internet telephony providers charge for a long distance call to a number outside your calling area, similar to existing, traditional wireline telephone service. Other VoIP providers permit you to call anywhere at a flat rate for a fixed number of minutes.
Your VoIP internet telephony provider may permit you to select an area code different from the area in which you live. This means that if your VOIP provider charges for long distance, then charges could be based on whether you call within your area code rather than geographic area. It also means that people who call you may incur long distance charges depending on their area code and service.

Can I Take My internet Phone Adapter With me When I Travel?
You may be able to use your VoIP service wherever you travel as long as you have a broadband Internet connection available. In that case it would work the same as in your home.

How Do I Know If I have a VoIP Phone Call?
The phone will ring like any other call.

Does the FCC Regulate Internet Voice?
The Federal Communications Commission (FCC) has worked to create an environment promoting competition and innovation to benefit consumers. Historically, the FCC has not regulated the Internet or the services provided over it.

Additional Considerations
If you’re considering replacing your traditional telephone service with VoIP, there are some possible considerations you should be aware of:

Some VoIP services don’t work during power outages and the service provider may not offer backup power

It may be difficult for some VoIP services to seamlessly connect with the 911 emergency dispatch center or to identify the location of VoIP 911 callers

VoIP providers may or may not offer directory assistance/white page listings. Aspects of these considerations may change with new development in Internet Voice technology. You should always check with the potential VoIP service provider to confirm any advantages and limitations to their service.

How to get broadband

by: neil shevlin
Getting broadband services getting easy, but research still required

Broadband Internet services have become more the norm today, unlike the dial-up days of the late 1990s. With greater amounts of information needing to travel at faster and faster speeds over the Internet and the greater number of telecommuters every year, the need for broadband Internet has stretched beyond the board room and into the home office. So it is clearly more important than ever for everyone to know how to get broadband.

Getting broadband service, like, for example, DSL, is not difficult. There are many providers, and even many phone companies are getting into the game today as well. But finding a service provider, while not being very difficult, also requires a self-evaluation first. One must ask themselves before seeking out a broadband service provider, just what they’ll be needing broadband service for.

For most people who work from home, they may only need reliable and speedy Internet access. They may need to transport documents, maybe some graphics to and from clients and employers. But they will likely not need to transmit video or graphics. But if they do need to transmit the latter, they may need to seek out higher bandwidth. But, again, if they are only sending documents that are not graphic intensive, a smaller bandwidth at a lower cost may be all they need, and then they can spend their savings on other aspects of their business or work.

After doing this necessary self assessment when looking at how to get broadband, it is important to check pricing on at least three broadband providers. Also, ask users of these providers about their experience. All of these broadband providers may boast the same thing, but the people who use their services are the true indicator of how they really perform.

After you match your needs with the best price and testimonial, the decision is yours whether you want to spring for a broadband provider. But chances are pretty good that even if you only spend a few dollars more a month for broadband, after awhile, you will wonder how you ever existed with dial-up service.

Another thing some people must consider when looking into how to get broadband is whether you have providers in your area. In some rare instances, certain providers do not have the infrastructure in place to give you their service yet. So while you may be hearing the raves from a friend across town about a particular provider, you may still have to wait and see if their service is present in your area. This has been the case, particularly, for cable companies getting into broadband Internet services. As they expand their infrastructure, some sections of major metropolitan areas have had to wait longer to get their broadband.

High-Speed Internet Access For Remote Canadian Communities

(NC)—We are in the information age dominated by an on-demand knowledge society. Canada is one of the most connected countries in the world and the Internet has become so central to our lives that many people can't do their work or stay in touch without it.
In short, today's world demands high-speed Internet access.

And the demand for speed is growing as the Internet becomes an essential part of modern life and new bandwidth-hungry services, applications and devices are rolled out.

But what if you're among the more than 7.5 million Canadians in rural and remote communities who don't have cable or DSL high-speed broadband access? Typically, these areas of the country have been underserved by the simple fact that the economics of a land-based system will never justify mass deployment.

Fortunately, there is a solution for many of these remote residents – a high-speed satellite Internet service offered by Bell ExpressVu's DirecPC. Essentially, the system uses the same Bell ExpressVu satellite dish as the Bell ExpressVu TV service, but works independently from the satellite receiver to deliver data to your computer.

How fast is satellite Internet? DirecPC features download speeds of up to 400 kbps - that's up to seven times faster than a traditional 56k modem.

In every day terms, that means users can download a 4MB audio file in 60-70 seconds compared with over 19 minutes using a 56K modem. Or download a 1MB video file in a little over 16 seconds compared with almost 5 minutes using a 56K modem.

It's a broadband Internet access service that is always on and is available to anyone, anywhere in Canada with a phone line and a local Internet Service Provider.

Increasingly, high-speed Internet is becoming a must-have service. According to Canada's National Broadband Task Force, the vast majority of Canadians are going to require high-speed Internet access to use new online services from governments and businesses that are increasingly placing information and products on secure Web sites. All aspects of our society are being altered by the availability of the Internet to the point that e-business and e-learning are seen by many as crucial to the development of our economy.

Without high-speed access, the benefits of these new services are generally restricted to Canadians living in the largest urban areas of the country. DirecPC satellite, however, levels the playing field for those living in remote or rural areas.

DirecPC is available from Bell ExpressVu dealers throughout Canada or by contacting Bell ExpressVu at 1-888-DirecPC (347-3272) or direcpcinfo@expressvu.com. For more information, please visit www.bell.ca/direcpc.

Advantages Of VoIP Broadband Phone Service

There are many advantages of VoIP broadband phone service. Over the next couple of years phone over Internet will be the norm for most homes and businesses.

Internet Phone Benefits. More than likely you receive many VoIP phone calls in the course of a week without realizing it. This is because the phone line quality for VoIP is the same as traditional phone services. If you are considering Internet phone service, you are making a good choice. Voice over Internet Protocol (VoIP) as it is called is quickly becoming the best value for telephone service. Most companies like Sprint and AT&T are already offering VoIP within their internal networks and are starting to offer it as a complete service offering.

How VoIP Phone Calls Work and Voice Quality.

The simple answer is that your voice is digitalized and transported over the Internet as well as over the phone company's private network using Internet Protocol (IP) service. A broadband phone call happens in real time just like on a digital TV, except you are using your broadband Internet service (DSL, Cable, or Satellite). Traditional phone services use analog, circuit technology. Because of improvements in voice quality and throughput of VoIP, small idependent carriers have already started offering VoIP to residents and businesses. Now most phone companies are using Internet phone technology over their private networks. This means that most of your calls today go over, at least in part, VoIP networks. This change in technology is a major factor in the drop in long distance rates in recent years. Now that many phone companies are extending VoIP service to the homes and businesses, we can now enjoy additional savings, great voice quality, and great features.

Price.

Low Price. Prices for broadband phone services start at under $10 a month. VoIP service is available to anyone in the world who has an Internet broadband connection. International and in-country rates start at 1.1 cents a minute or even unlimited for some VoIP monthly plans.

Broadband Phone. When signing up with a carrier you will normally have the option of using your own broadband phone, buying a broadband phone from the carrier, or getting a special adapter to connect your existing phone to your broadband connection. You can also elect to make VoIP phone calls using your PC. PCs normally do not need any special equipment, but many people purchase a wired or wireless headset. Broadband phones start under $40 and phone adapters cost under $10 depending on the VoIP carrier. Broadband phones look much like regular phones, but usually have a full range of digital features. Watch for promotional offers and you may get your broadband phone or adapter free when you sign-up with an broadband phone carrier.

No Contract, It's Prepaid. The other great pricing feature for most VoIP phone carriers is that there is no contract. You just pre-pay. This eliminates the risk of unexpected high phone bills.

No Regulatory Fees. Currently, there are no regulatory fees or special taxes with Internet phone call service. This can be a significant saving as many traditional phone plans have a 20% or more in fees and taxes added to the bill each month.

Features

Internet phone call service has many additional features over traditional phone services. Features include: most traditional add-on services (call waiting, voice mail, caller ID, etc) are standard, video phone option, travel with your phone number, service available worldwide (need high-speed Internet connection), your area code not tied to your geographic area, ultra-low International calling, more...

How Can a Broadband Cable Benefit You?

How Can a Broadband Cable Benefit You?
by: David Gonzalez
We are now well ensconced in a time when the Web is riddled with graphics, animations, sounds, and videos, bringing about a necessity for superior internet access such as that which broadband can provide. The fact is that anything less than the speed supplied by a broadband cable has become inadequate for today’s Web users.



Of course, if you use the internet only once every so often, you wouldn’t be as heavily dependent upon high-speed internet access as is provided by broadband, however, if you’re a regular user, it’s virtually a necessity.

But wait a minute…even though you use the internet, it doesn’t mean you know exactly what this high focus form of internet access actually is. So lets start there. In essence, broadband is a very fast form of internet connection. Broadband Will provide you with a noticeably faster internet speed than a dial-up connection.

Broadband used to be a challenge only because of it’s limited availability, however, today there are many ways that you can have a much faster connection. The delivery methods of broadband have been expanded to the following types of broadband cable:

- Copper telephone wires
- Cable TV wires
- Radio microwaves from local base stations
- Satellite microwaves from geo-stationary satellites

Now lets look at why this faster style of internet access is actually better. The benefits of broadband actually include much more than faster downloads. Broadband is the connection that is always “on”. As soon as you start up your computer, it’s already connected to the internet. For anyone who has waited for a modem to dial up and connect, the advantage of this is quite apparent. Furthermore, broadband allows you to download movies, music, and web pages that were virtually inaccessible in practical terms when using dial-up.

But the benefits of broadband aren’t just felt by individual users. Businesses, governments, schools, and communities can all experience the superiority that broadband cables can provide.

Here are some examples of benefits for each of those types of organizations:

- Businesses will notice an increase in productivity when large data files transfer quickly and directly among local and head offices, no matter the distance between the locations. Moreover, with the popularity of net-meetings and videoconferencing, a face-to-face meeting becomes entirely possible without the travel costs.

- Schools can now offer equal opportunities to their students no matter their location or funding. A student in a remote community is now able to use a broadband connection to receive violin lessons from the same revered instructor as a student in a large city. Moreover, rural students can take virtual field trips and see the same fascinating and educational museums as city kids.

- Local governments are now enjoying broadband benefits that let them provide one-stop shopping for town business transactions, as well as licensing, permits, billing, and utility payments.

- Communities have been quick to jump on the broadband band wagon to promote their local historical and other various tourist attractions. No other marketing resource reaches as far and as effectively as the internet.

There are so many fantastic benefits to a high-speed, broadband internet connection, that it is becoming as “basic” a need as a computer in today’s society.

Homecall Broadband

Homecall Broadband
by: neil shevlin
Caudwell Communications, telephony business from the Caudwell Group and owners of mobile phone company Phones4u announced in October their new phone line and broadband internet package. The broadband home service is known as Homecall.

The main advantage of Homecall over other services is that they can combine all your needs. A single bill every month includes your phone bill and internet bill. Because of their ties with Phones4u they often provide mobile phone promotions and their standard package includes free international and local calls, and cheap mobile phone calls!

Homecall don’t provide their ADSL themselves though, they do it through Tiscali Broadband. Although they offer they own services and support, Tiscali have a bad reputation when it comes to customer experience and also use the unpopular Datastream method of connection as opposed to IPstream.

With BT being forced to open up their phone lines for other companies to use directly, many companies have chosen to install their own equipment at BT telephone exchanges. On IPstream all customers are channelled down the main 155Mbit line which feeds directly into a BT controlled network. This means the ISP’s using IPstream have to pay BT, but the service is much faster. Datastream providers have their own 2Mbit circuit in each telephone exchange, so you are only sharing your bandwidth with the other people connected to your local exchange rather than all the bandwidth over the country. This means Datastream customers find their internet often running slower and not providing their full internet bandwidth, sometimes limited to slower than 56K dialup.

A recent poll by Homecall showed that the number one reason people surf the internet is to download music. Second was downloading adult services, third watching music videos, fourth listening to the radio and fifth was downloading movie trailers. Online gaming and family file sharing (i.e photographs) were also in the top ten. A Homecall spokesperson said "Broadband in the home has really taken off.”

Homecall offer no setup costs and all the equipment you need to get online. Their prices are competitive and there’s no usage cap on your bandwidth, meaning you can download as much as you want, although with the Datastream problems you may not be able to download that much anyway. If you go for Homecall broadband it is so much more beneficial to get a package deal including phone calls. This will save you some money on both phone and internet. Homecall undercut all of BT’s phone prices by a couple of pounds a month and give you more free calls and unlimited internet. Unfortunately their internet packages are of a slower speed than the main competition or slightly more expensive. Homecall offer 2Mbps and 512Kbps broadband access.

Homecall’s package is perfect for users who don’t want a download cap and access to high speed unlimited broadband. Combined with their phone package you can make savings on your BT contract and get loads of free phone calls all throughout the day. The only problem is you may end up having your speeds slashed if too many people in your local area are also on Homecall.

What are Your Internet Connection Solutions?

Of primary concern to all internet users is their actual connection to the internet.A user needs to look at all the factors and weigh the benefits and costs

Reliability - is the connection available 24/7, or do you get a busy signal?

Speed - at what speeds can a user upload and download files?

Costs - what are the setup and monthly costs for the internet connection service?

Support - is support available 24/7 and is it free or is there a cost associated with it?

Availability - is the desired service available at your location?

Available options with good and bad features include:Local dial up with phone company (local isp) - While this many times is the simplest, often times, they are the most costly and support can be an issue. Speeds are typically the slowest at 26k to 56k connection speeds.

Software file compression- If you only have 26k dialup isp connections available to you or you want to speed up your DSL connections, this is an important option you should take a look at. With this type of software you can increase your internet connection speeds by as much as five times for very little money. Popular software products that accomplish this are ActiveSpeed, PropelAccelerator, Dr. Speed, and SuperSpeeder, Highly recommended solution to increasing your browsing experience.

Local dial up with national firm - This is by far the most popular with companies like AOL, People PC, Juno, EarthLink, and Netzero providing this service to millions of users. These certainly are the most cost effective and provide excellent 24/7 support. With the high speed upgrade options you can approach 112 k speeds. If the company has a local or toll free number available in your area, then this alternative provides the lowest cost isp internet connection.

Cable connection - If cable TV is available in your area, many firms also provide an internet connection for an additional fee. Requires special cable modem. Speeds are anywhere from 512k to 10Mps.

DSL or digital service line - Many local phone companies are providing this service to selected areas. Requires installation of DSL modem on your computer and speeds typically are from 512k to 9Mps. The distance from the local hub also affects your speed. You will pay 2 to 3 times the costs of basic dial up.

Broadband - Is a term loosely thrown around that is applied to a DSL, cable, wireless, or satellite internet connections. Technically broadband is a minimum of 1.5Mbs but is used to market products with bandwidth as low as 512k. When you hear the term broadband used, think like "health food", an undefined marketing catch word.

Wireless internet connection - This option is available in limited area's and requires a wireless modem on your computer. Speeds typically are 2Mbps and this is a flexible approach as you do not need to be hardwired or plugged in. Available in many metro area's.

Satellite internet connection - This is the perfect solution for remote area's if you require a high speed internet connection. Upload and download speeds are different and in some cases you can only download via satellite and are required to upload via dial up. This is the most expensive alternative, but you can get service basically anywhere in the world. Speeds starting at 500k are available. Contact Directway for dependable and fast satellite internet connections.
