Distinguish between Broadband and DSL Connections

broadband-and-DSL-connections

As the internet world is flying by leaps and bounds every year, you need to make sure that when it’s time for you to get your own connection, it’s at par with the latest technology in order to have access to high-speed, hassle-free internet services.

Terms like broadband, DSL and wireless technologies including fiber optics or satellites might be thrown your way during your research. While the terminologies may stump you for a moment, here is a brief breakdown on some basic stuff you will need to know.

Broadband basically refers to internet signals that are of high bandwidth or capacity, with quite a number of internet services being referred to as broadband also by virtue of their high-speed broadband transmission. Broadband access internet access is definitely faster than the traditional dial-up system and includes technologies like DSL (Digital Subscriber Line), coaxial cables, fiber-optic cables, satellites access or other wireless systems. The point to be noted here is that while all these technologies can be loosely referred to as broadband, the reveres doesn’t hold true; for example not all broadband connections can be considered as DSL!

Earlier, broadband internet was defined as downstream speeds faster than 512 Kbps; this definition has been getting moderated with time and currently stands at around 4 Mbps or more of internet connection. A number of DSL aren’t this fast.

DSL, or Digital Subscriber Line is a type of wired broadband internet connection that utilizes the wires of a telephone service to deliver high-speed internet access. Depending on the location and distance from the internet service provider (ISP), speeds can range from 256 Kbps to 24 Mbps. The quality of the telephone lines and the material used also matters when it comes to deliverance of speeds. The telephone wires used are typically copper (twisted pair) wires. Other than this, the DSL plan that you are subscribed for also matters when it comes to broadband speeds availed.

Another advantage of DSL connections is that you don’t need to drill any further holes into your walls as it can accessed over your telephone wire – all you need is to plug in a DSL modem! This type of broadband connection is now slowly getting phased out as other faster wireless systems like cable and fiber optics are taking over the scenario. Cables can provide speeds that are 100-300 Mbps while fiber optics can provide speeds up to 1000 Mbps.

So when choosing an internet service provider for yourself, a DSL provider may not always be best as connections tend to deteriorate with distance from the ISP provider. That being said, wireless connections also tend to suffer from presence of trees or constructions obstructing the way. The best way out would be to ask your neighbors which connection they are using!

What are 2G, 3G and 4G Networks?

what-are-2G-3G-and-4G-networks

The wireless option for internet data has been adopted far and wide in India with companies offering 2G, 3G and 4G speeds to their subscribers. Over 75% of Indian internet users are believed to access data over mobile devices, with the craze for hand-held internet devices increasing by leaps and bounds. However, most of them have issues with the internet speeds being offered under the guise of 3G or 4G.

To begin with, let’s first clarify the difference between the 2G, 3G and 4G networks; it might sound a little complicated in the beginning, but it’s mainly to do with internet speeds. The ‘G’ here stands for generation, so it becomes clear, that the 4G has to be the latest technology with highest speeds of above 100Mbps. The speed of data transmission between 2G and 3G, that is between second generation and third generation technologies, is in the faster download speeds and faster access in the 3G networks. TRAI (Telecom Regulatory Authority of India) is of the view that a 2G should have minimum data download speed of 56Kbps while 3G should have a minimum download speed of 1Mbps (95%success rates).

However, do note that not all phones are designed to be used with all the above-mentioned technologies as they come with different band compatibilities. The 2G has only 4 bands while the 3G has 5 bands and 4G has about 7 bands. So when buying a phone, make sure its compatible with your data frequency needs.

Interestingly, the first generation (read 1G) commercial cellular network took off as early as in the 70’s, but only took root by the 80’s. The radio signals used were analogue and as they degrade over time and distance, the voice quality wasn’t too great.

This paved way for the introduction of the 2G or second generation GSM network technology in the 90’s which allowed voice and data usage across different networks and allowed roaming for the first time. Along with greater privacy, it also included the 1G features of SMS, internal roaming and real time billing based on services.

The third generation technology, 3G, was introduced commercially in 2001 and supported a wider range of applications as well as increased data transmission at lower costs. Some of these applications included wireless internet access for video calls, chatting, conference calls, emails, mobile gaming, music, video on demand, etc. This introduced a whole new meaning to the mobile phone.

The fourth generation technology, 4G, was introduced in 2010 and is an IP-based network system that provides consumers with higher speeds, better quality as well as greater capacity for data services and multimedia over the internet at lower rates. And things are only going to get better as the fifth generation, or 5G network will soon be rolled out in India too.

Wired Connections and Optical Fiber Connections

wired-connections-and-optical-fiber-connections

With technology gaining the upper-hand in almost all aspects of our lives, it is becoming increasingly important to know more about the different ways you can access the internet, a feature in our life that is increasingly keeping us connected to our work, family, social life, communication, news, education, entertainment, business, important information, etc.

What many people aren’t aware about is the importance of bandwidth, or speed at which you can access the internet as well as the different materials used to connect to the internet. The speed of the internet helps you to send and receive data at a faster rate, cutting down on time wastage, loss in productivity and sales. This aspect of internet use is further aided by the method used to connect to the internet.

The three main ways of accessing are through fiber optic connections, copper wired connections and the most recent entrant, the wireless connection. With all three being readily available in the marketplace, you need to know a little about their features and benefits before deciding which one is most suited to your needs.

Wired connections are more used in businesses and homes and include the fiber optic cables which are made of glass or plastic and very hardy to degradation, as well as the copper-wired connections.

Copper is an element and was first used about a hundred years ago when the telephone was introduced. Though it’s great for carrying voice signals, it has limited bandwidth use. It uses electrical signals that tend to degrade with the passage of distance, and are further affected by weather, moisture, etc. This means that signals are weaker and less data can be passed through. However, that having been said, copper wiring is better for rural areas as telephone wiring is already laid out, and it comes out cheaper on the pocket too.

Fiber optic cables are new entrants and transmit data through thin strands of transparent material; there is faster transmission of data through photons which travel at about 31% slower than the speed of light in fiber optic cables. Electrons passing through copper wires travel at less than 1% of the speed of light on the other hand.

There is less loss in signal through fiber optic cables, which use light instead of electricity as their copper-wired counterparts do. It’s been estimated that fiber loses about 3% of its signal strength over 100m, while copper wires lose about 94% over the same distance!

Aside from all these plus points, fiber-optic cables do not degrade easily either and are increasingly being taken as the gold-standard in high-quality data transmission. Time for wired cables to be replaced by the relatively newer fiber optic cables….

 

Wi-Fi and Wireless Broadband – are they the same?

Wi-Fi-and-wireless-broadband

For some time now, the words Wi-Fi and wireless broadband have been used to mean the same thing, which is grossly wrong. With the world evolving so fast in internet technologies, it’s only right that the correct nomenclature is used to prevent any confusion in the future.

To begin with, Wi-Fi is a facility that uses radio waves to provide network connection to computers, smart phones, etc, within a restricted area. The term Wi-Fi stands for ‘wireless fidelity’ and uses a wireless access point or router to transmit signals through a WAP encryption. It uses LAN (local area network) technology and operates in an unlicensed spectrum over a short range, with the area covered being just up to a few limited meters, ideal or home or office use. Wi-Fi is basically a local wireless network that you create using a router connected to the WAN port of your broadband modem.

To access Wi-Fi, you need to have a wireless router that you connect to your existing internet connection through the broadband modem. Upon connection through the WAN outlet, you are now ready to use any device that is Wi-Fi compatible to access the internet. Most devices that use the internet are…

Imagine a situation without Wi-Fi, where to get broadband connection to the numerous internet-enabled gadgets that we use daily, a separate networking device would have to be installed! Imagine the amount of wiring that would require, the expenses incurred with numerous broadband connections, – as well as the restriction on ease of mobility around the home or office with your device. Conjures up unthinkable images of horror in this modern world, right?

Coming to the broadband or wide area network (WAN), the internet connects you to computers around the world via numerous networks and tons of routers. With a broadband connection, you are no longer isolated, but part of the giant worldwide network. And when you access broadband through a router, you are basically using wireless broadband as you don’t need to sign up for a new broadband connection to access the internet. Any DSL or Cable broadband service can be made into a wireless broadband source by using a wireless router.

Another type of wireless broadband is the dongle or small Mi-Fi unit which goes with a mobile 3G or 4G broadband connection, giving you the freedom from cables. All you need to do is plug it into your device and use as they don’t require electricity. It’s designed for those who are always on the go, even when they are abroad.

To sum it up, the Wi-Fi uses local area network (LAN) and is just a way of bringing the internet to your device via a broadband modem. Wireless broadband on the hand refers to cable-less use of broadband internet.

What are the Different Kinds of Internet Connections?

different-kinds-internet-connections

Technology is evolving at a rapid pace and so is the internet speed to complement it. An increasing number of devices are now connecting to the internet and faster internet speeds is the need of the hour. Different ways of accessing the internet have also been evolving over the years, however as with all things, there are some pros and cons related to these different kinds of internet connections. Let’s take a closer look at some of the different ways of accessing the internet today:

Dial-up (Analog) – This is the oldest and cheapest system; however it’s very slow and unreliable. To connect to the internet, your computer first needs to dial up a specific phone number. Here, the computer providing internet access is known as the host and the receiver is known as client and basically acts as a dummy terminal. So basically, the host receives the data over the internet on behalf of the client and passes it to them. The client connects to the host via a modem which allows surfing up to about 56Kbps.

DSL (Digital Subscriber Line) – Unlike the dial-up, this internet connection is always on, and it uses two lines, so your phone connection is still free when your computer is connected to the internet. It uses a router to transport data and the connection speeds are much better at anything between 128K – 8Mbps.

Cable connections – Here, a cable TV company provides coaxial cables right into the building to deliver internet connection. Usually a splitter is placed outside the building such that two separate cables enter into the building for cable TV as well as for internet usage. There is greater bandwidth provided over the coaxial cables with speeds up to 512K – 20Mbps.

Wireless connections (Wi-Fi) – This is one of the newer interconnection types and as the name suggests, doesn’t use telephone or cables, but depends on radio frequency bands instead. This internet connection is always on and can be accessed from just about anywhere! It’s typically more expensive and has better coverage in metropolitan areas; speeds can vary anywhere from 5Mbps – 20Mbps.

Satellite Connections – Internet can be accessed via a satellite that orbits the earth but due to the enormous distance the signals travel from the earth to the satellite and back again, speeds are slightly slower than DSL and cable connections. Typical speeds range between 512K – 2Mbps. A transceiver placed outdoors in line with the satellite directs signals to a device placed indoors that connects to the computer or device.

Cellular connections – This Wi-Fi technology is mainly utilized by mobile phones. The speeds vary depending on the provider, but are usually 3G or 4G. A 3G refers to a 3rd generation cellular network, garnering speeds up to 2Mbps. A 4G is a 4th generation cellular network that is touted to achieve peak mobile speeds of 100Mbps – but ground reality is usually about 21Mbps….

How and when did Internet come into Existence?

How-and-when-did-internet-come-into-existence

The advent of the internet revolutionized the world of computers and communications incomparably. Today, it is represented as one of the most successful products of sustained investment and commitment towards research and development in information structure. The internet has the ability for world-wide broadcasting, a mechanism to disseminate information as well as serve as a medium for collaboration between computers, irrespective of their geographical location.

The stage for this ever-evolving internet technology was set by the invention of the radio, telephone, telegraph and the computer followed by an integration of their capabilities. As can be expected, the invention of this expansive technology cannot be attributed to a single individual but rather to the works of a dozens of pioneering engineers, scientists and programmers; they each developed new features that were eventually integrated together to become the ‘information superhighway’ as we know it today.

The history of the internet began with the introduction of the first electronic computers in the 1950’s with the first prototype of the internet coming into existence in the late 1960’s with the creation of ARPANET (Advanced Research Projects Agency Network). The first message sent over the ARPANET was the amalgamation of the hard work of the US government’s Department of Defense and scholars from four universities located in UK, France and the US.

It was the early research into ‘packets switching’ and ‘packet network systems’ that popularized the idea of an ‘Intergalactic Network’ of computers. This concept of effective transmission of electronic data later became one of the major building-blocks of the internet. Though ARPANET is the research product of the ‘Cold War’ and was funded by the US, the technology which allowed numerous computers to communicate over a single network continued to grow into the 1970s when Robert Kahn and Vinton Cerf created the Transmission Control Protocol and Internet Protocol that sets standards on transfer of data between different networks.

This was the stepping stone to the creation of ‘Network of Networks’ which then evolved into the modern internet. Our online world started taking on a more comprehensive shape in the 1990s when computer scientist Tim Berners-Lee created the World Wide Web. The web is the commonest way of accessing online data via internet websites and hyperlinks. Today, this web has developed into an unending trove of information that the human population across the globe accesses on a daily basis – without thinking of how it originated in the first place! So what began as an initiative of the US military computer network program has now become a global communication tool that helps millions of computer networks share a common addressing scheme. Today, the internet has become a crucial tool for online information, entertainment, commerce and social networking.

 

Is Wi-Fi Harmful to Humans?

is_wi-fi_harmful_to_humans

Let’s face it; humans are very insecure creatures, with death being the glaring root cause of most of their fears. And when it comes to looking for potential causes for deaths or ill-health, there is no dearth in possible culprits. Wi-Fi is no less a raging topic when it comes to its effects on human beings.

You will find numerous articles stating so-called ‘facts and figures’ on a plethora of side-effects ranging from infertility, insomnia to hyperactivity and cancer. There are laughable posts on social networking websites propagating this fear and presenting Wi-Fi as a silent marauder lurking in the shadows waiting to strike with its mind-boggling cancer-producing abilities!

The basic psychology behind this propaganda is that humans like to be in control of all that surrounds them, but death forestalls them. By propagating possible reasons that could lead to death, humans feel as if they have conquered part of the ‘unknown’ harbinger of death, and hence feel better about their immortality, or rather lack of!

As an example, you can look at the incidence of mobile phone usage over the past twenty years. Over four billion people use these Wi-Fi enabled phones, yet the incidence of brain tumors have remained unchanged! Although the World Health Organization recognizes the public’s concern over radiation posing health hazards, numerous studies have been conducted and all seem to show the same result that electromagnetic radiations between 0-300GHz do not pose any negative health hazards. In fact there are a set of safety standards put in place for all devices that emit electromagnetic radiation; these limits ensure that the exposure that you get from your Wi-Fi enabled devices is way, way below the safety limits.

Being on the judicious side, the British Health Agency has stated that even though there is no consistent evidence to indicate that Wi-Fi affect health adversely, to be on the precautionary side, the matter should be kept under ongoing review…

However, not to get carried away, let’s talk about radiation; though the word itself is scary and brings back memories of the Cold War era when people had backyard bomb shelters, radiation isn’t only about death and oceans and lands becoming inhabitable. It’s also about warm, golden sunshine which makes life possible on earth. It’s also the way we can tune into our wireless radios or change channels on TV.

Basically what it boils down to is ionizing and non-ionizing radiation of which ionizing is dangerous and includes the x-ray radiation, gamma radiation, UV radiation, etc, with the key element being the wavelength. However, there is no biologic mechanism by which non-ionizing radiation (read Wi-Fi) can cause harm.

Maybe it’s time the naysayers got wiser now and concentrated on real threats to life – like going for annual health check-ups and staying off the phone while driving!

How to Choose the Right Modem for your Broadband Plan

how_to_choose_the_right_modem_for_your_broadband_plan

It has been documented that the advent of the broadband internet has resulted in increased turnovers in businesses, making transactions and communication much easier as well as faster. When you are choosing an internet connection, you also need to take the time out to choose a suitable modem that will match your broadband needs.

Without knowing it, you could even be losing significant speeds on your connection package due to an unsuitable modem. The actual internet speed of your broadband connection depends on the speed of the modem, the Wi-Fi connection, the switches as well as the broadband data plan itself. So then, what exactly is a suitable modem? Generally, wireless modems are connections of choice for offices where it’s easier to connect numerous devices this way. Since a modem can connect only a single device to the internet, you would need a Wi-Fi device, or a router to be able to connect to more than one appliance at any given time. A combination of a modem and a router is known as a gateway.

Many internet service providers offer a gateway, but then it does have its disadvantages too. Getting a separate modem and router allows more flexibility in case you want to upgrade your network at a later date. If you want to upgrade your broadband speed, you will only need to upgrade the modem or if you want your network to have a faster speed or more settings and features, all you will need would be to replace the router. At Asianet Broadband internet services, we understand your needs and provide the best model of modems in a separate format.

When choosing broadband plans for businesses, you will need to consider the number of people who will be logged on at the same time on the net as well as the activities they will be engaged in. Activities like uploading or downloading large files of high resolution images or videos are best with an FTU (fiber termination unit) modem. The FTU is the final part of the fiber that is located within the house or office. A modem is placed onto the FTU when the customer wishes to connect to the services of the provider network.

The modem is basically a signal converter as it translates the internet into a usable form by your devices. It also connects to your office network. The type of modem used affects the wireless range, the strength and speed of the signal as well as its security. When buying a modem, it’s better to buy one with the capacity to deal with higher speeds of broadband data plan, as your needs may increase over time. This would allow you to avoid paying for another upgraded modem at a later date.

Sometimes you might need an additional signal repeater if the floor size is too big or if there are thick walls or obstacles in between. And when it comes to comparing modems, it’s the technical specifications on it that make the difference. The main features to look for is the wireless capability of the model; most models will show digits like ‘802n 2.4GHz’ referring to the standard its using as well as the bandwidth.

 

Choosing a High-Speed Internet Plan for your Business

choosing_a_high-speed_internet_plan_for_your_business

 

When it comes to choosing an internet service provider for your business, whether it’s small or medium-sized notwithstanding, you need to consider a number of factors first. The obvious variables that come to mind include cost, availability, reliability and speed. Aside from this, you should also have an idea of the number of people that will be using the internet at the same time, as this affects the actual speed of the service you will be getting at the end of the day.

With so much competition going on in the business sector, you need to keep up to your game and ensure that your business is up to speed…..just like your internet. Since internet technologies are getting more and more advanced, you need to get a proper understanding about the differences between them before taking a decision. DSL (digital subscriber line), cable, satellite and fiber-optics are some of the different ways of accessing the internet. The satellite connections obviously come with the disadvantage of being affected by local weather conditions, and during monsoon, this could turn disastrous. And the DSL connections work optimally only when located close to their central office. The fiber-optics option is a little heavy on the pocket on the other hand, thus making cable connections the most lucrative. At Asianet Broadband, we offer cable broadband internet connections that can be bundled with cable TV at more convenient tariffs aside from having one of the best and most reliable networks in Kerala.

When selecting a broadband plan, you will need to check the download as well as the uploading speeds. Most people focus on downloading speeds as they wouldn’t want their workers sitting twiddling their thumbs while waiting for data to download. Similarly, the uploading speeds are important because after hitting the send button, you want to know that it will reach the client or customer at the earliest because sometimes time means money, especially over the internet.

And if you are backing up large files on to the cloud or using some of the new cloud solutions, uploading speeds can become a really important factor. Video conferencing has now become a relatively affordable and easy way of communicating with company branches and clients, and you really wouldn’t want to be put through the embarrassment of having cuts and pauses during communication. So don’t just get carried away by download speeds, check the upload speeds too.
Another important factor is the reliability of the ISP. Do they have a 24×7 technical support system and is this service free? – As many ISPs charge for their technical support, or the customer service is very slow and unreliable.

Aside from this, some ISPs place a limitation on the amount of data you can upload or download and could charge you extra at higher rates if you go above the limits. Better option is to go for a fixed plan where you have regular billing without the fear of overage charges. For this, you will need to have a general idea of how much bandwidth you will need per month. And opting for the annual scheme is always better as it comes loaded with some freebies that include 2-3 months free usage.

Armed with all this info, you are bound to choose the right ISP!
