Business Prospects Of Wimax -- An ISP point of View

2008-06-10T04:34:00.001-07:00

The prospects for WiMAX technology as a viable business opportunity are often the subject of debate amidst numerous actual or perceived challenges. Applying these innovative insights can make these arguments and challenges disappear.

Unlike most people's expectation of rural deployments, you might consider targeting SME's in urban areas. There are several reasons for this:

?There is a growing demand in business for bandwidth capable of carrying symmetrical traffic, for voice, applications and uploading of larger files.

?There is a small but growing need for separated last mile services. Currently, however many wired service providers you have, they all use the incumbents' last mile infrastructure based on its nearest telephone exchange location unless you have paid for an expensive dig from the next nearest exchange. This leads to single points of failure and the potential for business communications to be down for days, as can happen say with a cable duct fire somewhere in the spoke.

Your worst case environment would be a very high-density urban area with lots of interfering buildings, has multiple fibre networks, ADSL and SDSL in every exchange, hundreds of competing suppliers, a restrictive property planning regime with many 'listed' buildings, and no spare spectrum for FWA except the public 5.8GHz band.

To do this, because of the scale of competition from other service providers, your model needs to be disruptive. It has to offer things that businesses need (like QoS, toll-quality VoIP, high-quality video, symmetric bandwidth, higher capacities and network separation etc) at a lower cost.

This means stripping all unnecessary cost out of the model. You'll benefit from a quality RF planning tool that gives you a major advantage over other operators - mapping exactly where you can provide service, how to set up the customer antenna, what bandwidth can be achieved etc, based on your base-stations. You need to know exactly how to tune base-stations to avoid blackspots - without needing an RF team.

Although Wi-Fi and WiMAX often get confused, they are very different from an operators perspective. Wi-Fi is plug and play with no control over the wireless interface. WiMAX is not, it behaves more like a carrier ATM network. Wi-Fi is built into laptops and handsets, whereas FWA WiMAX requires larger standalone receivers (yours should mount on customer rooftops for optimum utilty).

The benefit is that WiMAX is very spectrally efficient, at least 50% more so than 3G networks, so it has much higher data-carrying capabilities in limited spectrum. All Wi-Fi shares the same public spectrum - WiMAX can work across a wide range. Wi-Fi provides service over a range of 100m, your WiMAX needs to provide 10Mbps over a range of 1.3km from a base-station non-line-of sight.

WiMAX can create carrier-class networks, Wi-Fi cannot ?not even with mesh networks. However, Wi-Fi with WiMAX backhaul gets some of the benefits of WiMAX as the backhaul such as VPNs. A lot of WiMAX customer equipment will come with Wi-Fi built in.

Dont wait for mobile (802.16e) WiMAX ?your experience with vendors may be that they're around fourteen months to two years behind on their promised delivery dates, and further delays could occur to key requirements. Dont expect good enough 802.16e equipment to build a network with until late 2007 at the earliest, and no usable CPE until 2008 ?as its mobile battery life is crucial and that will take time to get right.

There are big enough markets for FWA now. The most important thing is to grab the scarce resources first ?spectrum etc ?and make them yours. Except in those undeveloped countries without a mobile operator, mobile WiMAX will be very difficult to establish against incumbent operators with large installed bases because the areas covered are important to customers ?which is not a consideration for FWA.

What's The Relationship Between Bandwidth And Latency?

2008-06-09T04:20:00.001-07:00

So what's is the relationship between bandwidth and latency? If your internet connection speed has the proper bandwidth, why does latency slow it down? Or does it? Just how exactly does latency affect your internet? These are just some of the common questions asked......what follows is some answers in both technical and layman's terms.

Latency is the time it takes your data (packets) to get from point A (your house/modem) to point B ( the destination). Latency happens because of each of the "stops" your data has to make on the way to point B. These stops, called hops, are the different routers and in some cases servers across the internet that handles and routes traffic accordingly. The more hops that get added into the route of your data, the higher your latency will become. The farther away point B is, typically higher latency is experienced, simply because there is more distance and hops encountered. Also, each of these hops can also become busy so to speak, therefore the busier they get the more time it will take them to respond to your traffic requests, hence higher latency.

Most file transfer over the Internet uses TCP/IP. The receiver constantly sends messages back to the sender (ACKS) letting it know all is will or if not which packets need to be resent. If the channel has high latency this reverse communication take too long causing transmitter to stop sending until ACKS are received.

TCP also has a slow start mechanism. The sender has no idea of end-to-end channel capability. A slow start is designed to prevent overwhelming intermediate slower links.

Esentially, your bandwidth is the speed between you and your ISP, anything outside that, your ISP has no control over.

Actually, latency may or may not be an issue. Because latency is the delay between getting information from point A to B, it's much more of an issue in interactive applications then large transfers.

With large transfers, if your bandwidth is sufficient, reliable, and properly configured, you won't notice much of a latency issue with high latency connections. Once the "pipe is primed", the data is flowing at full speed. As long as the ACK packets are returned at a regular interval frequent enough that retransmissions don't occur, the flow will be steady and the only delay is really just during the initial startup of the transfer.

However, with interactive applications, that initial delay is what really can kill you. While it's exaggerated, say you have a 1 second latency and sending a packet takes 1 second. If you are sending a file that's 10 packets long, your total connection time is 11 seconds. If you are sending a single packet and waiting for a response back of a single packet, and you do this twice, your total connection time will be 8 seconds but yet you only sent 40% as much traffic.

Web traffic is kind of in between the two. It's not typically a large transfer, but it's not highly interactive like a online game. Typical page traffic is short bursts of requests (high latency) followed by longer periods of inactivity while you look at the page. There are a few tricks that can be done to help reduce this as an issue. There are proxy servers and pre-fetch utilities that will "preload" the page for you. During that time where you are looking at the page and your connection is setting idle, the prefetcher can download pages that the current one is linked to. When you request one, hopefully the page has been cached and can be displayed much quicker. If not, you are no worse off then having to wait for it to be loaded. This can work good for more static pages but if you are looking for something for dynamic pages (e.g. Google Maps), a prefetcher doesn't work as well or at all. Also, checking to see if your browser is using the appropriate number of connections can improve things.

The bottom line is there is a relationship between bandwidth and latency. But it may or may not be an issue.

Internet Marketing Tips - Good Cop Or Bad Cop?

2008-06-06T23:47:00.000-07:00

If this sounds like a strange title for an article on Internet marketing tips, keep reading. Eventually, you'll understand exactly what I am talking about. See, there is more than one way to reach your prospects. What works for you will eventually come down to your own personal preference and style. Ultimately, you will need to test these two methods to see which works best for you.

Let me go on record by saying that I neither condone nor condemn either of these methods. I am only acknowledging that they exist. I don't want this to turn into a moral debate. There are marketers who use both these tactics. Both can be used successfully. The key is understanding them both and the consequences of their use.

Let's take good cop first because that's the easy one to use. Good cop is where you approach your prospects with a nice friendly email, sympathizing with their situation and offering your help. You speak to them like you're their best friend. The approach is non confrontational. It would be very difficult to put anyone off with this type of approach.

The problem with it is that it's also very lackluster. Prospects have turned a deaf ear to this feel good approach for the most part because the majority of marketers use it. The message received by the prospect is one that has been done to death. Therefore, it becomes very difficult to convert the prospect into a buyer unless you are very convincing or can show an awful lot of social proof.

The bad cop approach is when you pretty much tell your prospect that if they don't get your product, they're going to end up on the street with a monkey and a tin cup begging for spare change. The Rich Jerk, as you might recall, used this approach. He had quite a mouth on him. It worked for him. But it won't work for everybody. For one thing, you need to know your target market. The Rich Jerk knew his. He tailored his message to this market and it translated into millions of dollars in sales.

Ultimately, you have to decide which approach you want to use. They both can work. As long as you understand the pluses and minuses of each, you'll be fine.

Of course, you can always try to find somewhere in between the two.

To YOUR Success,

HTC Shift - The Ultimate Mobile Broadband Device!

2008-06-06T22:19:00.001-07:00

In a world where broadband internet access is everyone's goal, one device rules them all: the awesome HTC Shift.

Due to be released on Orange very soon, the HTC Shift is all set to shake up the world of mobile broadband, because it is, simply, the ultimate all-in-one solution. Combining all the good stuff of a UMPC (Ultra-Mobile PC, to the uninitiated) with a built-in HSDPA modem, it's the perfect tool for getting the internet on the move.

Features of the HTC Shift

Known round the world as an Ultra-Mobile PC, or a sub-laptop, the HTC Shift is an absolute powerhouse of a device. The trap many are going to fall into, though, thinking it's a mobile phone. Because it's not, it won't do phone calls (and dear lord, if it was, that'd be one BIG mobile phone!) What we have here is essentially a laptop in a squashed-down body. You know it's a fully featured PC, because it comes complete with Windows Vista Business, the latest in the long line of Windows operating systems, designed to give you all the grunt and power of a what you might call a 'proper' laptop. But combined with that, it also includes a stripped down version of Windows Mobile. Why, you may ask? Well, once you've finished using one of the many programs in Vista, you just switch it to mobile mode, and you get a lot of functionality, and you get your messages, without Vista being left on, draining the battery. That's just an awesomely clever thing for HTC to have built into the Shift.

And then, of course, you have a long, long list of other features. You have full Office functionality, you have full internet functionality and of course, full email functonality. So, whether you're using the HTC Shift for work, rest or play, it will instantly shift (geddit?) into whatever gear you need! Add in to that a massive 7 inch screen, and security in the form of biometrics (fingerprint scanner, the ultimate in security, to you and me), and it makes the HTC Shift one hell of a powerful device.

Mobile broadband - the future!

But the HTC Shift mobile PC's real party trick is mobile broadband. At speeds of up to 3.6Mbps. Built in. Just imagine that for a second. You're out on the train, trying to organise tickets to go see a film after work. The cinema's automated booking service is a nightmare. But you're not worried, because you have an HTC Shift, so you change it from Windows Mobile to Vista mode (a process that takes all of, ooh one button-press!), and book the tickets online. And then jump on Messenger and tell your friend the tickets are booked without having to pay for a phone call.And all the time you do it, you'll be getting that lovely warm feeling inside, knowing that with mobile broadband, you're getting internet speeds twice as fast as the average your friends get, sat at home!

Understanding DSL Internet Service

2008-06-05T05:05:00.001-07:00

DSL or Digital Subscriber Line is a type of broadband Internet connection. This type of broadband Internet requires you to have a phone line. Unlike dial up, you can actually use the phone while you are connected to the internet.

What are the benefits of a DSL Internet connection? DSL allows you to have faster internet connection than a dial up. It can offer faster access to information, faster downloads and much more.

Here are some of the benefits you can get from a broadband DSL Internet service.

Unlike dial ups, DSL allows a subscriber to make and receive phone calls while having an active internet connection. Dial up internet does not allow this, if someone calls you, your phone line will be busy. A DSL line also keeps your computer online as long as your computer is turned on.

With DSL you can talk to your friends, family or business associates with a web cam in real time. You can easily connect a microphone, web cam on your computer, and start using these accessories right away. This may be possible in some dial up, but since it has low speed, the data sent and received will usually be delayed or choppy.

Since you can actually use your voice in the internet in real time, you no longer need to call families and friends using expensive long distance calls from your traditional phone.

DSL also enables you to use VoIP technology. This technology virtually replaces your traditional phone with the internet. VoIP has free features your traditional phone company consider as additional features and chargeable.

Video Conferencing
Caller ID
Call Forwarding
Call Transfer
Call Waiting
Ringtones
Voice Mails
Free Long Distance Calls

These are just examples that VoIP offers and a lot more features are available.

Since you can conduct video conferencing, you no longer have to travel to meet with your business associates, therefore, saving you from travel expenses.

Another benefit from DSL internet is that you can play audio and video streams in the internet smoothly and without interruptions. You can now play your favorite internet radio stations while you surf the web or play your favorite music videos in the internet.

Playing online games that requires high-speed internet is now possible with the DSL internet. You can use your own PC or gaming consoles such as the PS2 or Xbox to play with other people from around the world and create an online community with adventure games.

Students can also improve their studies by using the DSL connection. Since DSL provides high-speed internet connection, students can now research more webpage that are required for their studies.

In dial ups, low speed internet connection restricts a students research to just a few webpage. This is because in dial up, loading webpage is too slow that a student will just stick to one or two websites to save time and money to do their research.

Online businesses can update their websites much faster in DSL than in dial up. Updating website for online businesses is crucial to inform their customers about the products they are selling.

Today, there are many DSL service providers in the market; choosing one is up to you. Research about the companies that provides this service before you buy their service and you can be sure about the quality of the DSL connection.

Ask your friends and family first who have this technology in their homes or businesses can also help you choose which DSL provider you want to work with.

Bob Hett has extensively covered the Internet Service Provider industry as an analyst and has researched the various companies for factors based on price, reliability, support and overall quality. Learn more at DSL Internet Service
