WiMax, Competitors Vie To Create Powerful EcoSystems

Several very interesting issues are at play in the rollout of wireless broadband technology. Indeed, the landscape that will dominate the next decade and beyond is being created now, as WiMax increasingly consolidates on one of two initial versions and steels itself for competition against other approaches.

The situation is fluid. Initially, the WiMax plan - to the extent that one existed - was for stationary and mobile versions to share center stage. Soon, however, it became clear that the mobile version could do just about everything the stationary version could. Thus, the impetus behind the stationary version began losing steam, said Monica Paolini, the founder and president of Senza Fili Consulting, in an IT Business Edge interview.

A lot of operators currently are deploying mobile WiMax. They are using it for fixed services. It's called mobile, but they can use it for both. On the other hand, fixed pretty much is just for fixed. Mobile WiMax allows you to roll out a network that supports fixed and mobile. The issue is having an infrastructure that can support all users. A lot of carriers will skip fixed WiMax, but offer fixed services using mobile WIMax technology.
The big issue is what operators will do after 3G. Mobile WiMax is one option. two others, according to this piece in internetnews.com, are LTE (Long Term Evolution) and ultramobile broadband (UMB). So far, WiMax has gotten most of the press, though the technology may be hitting a speed bump. Earlier this month, The Wall Street Journal speculated that sprint, which had publicly anointed WiMax as its 4G technology, may be looking to make a deal with Clearwire, a company that now has a proprietary version of the platform in the field and will roll out the standardized version when it becomes available. While such a deal may make sense, it could be perceived as a diminution of Sprint's embrace of the technology.

This is a sector in which partnerships and joint ventures will be vital. Paolini thinks that a battle between LTE and WiMax will not be decided by a drastic difference between the technologies, but by the direction in which the industry, as a group, decides to go.

Both LTE and WiMax use OFDMA [Orthogonal Frequency Division Multiple Access]. Both have IP cores. There certainly are differences in the technology, but one is not a lot better than the other. performance itself does not determine selection for mobile operators. It's more what the ecosystem is like, what the mobile community as a group wants to do.
Though the race will be close, one technology will dominate because of the fundamental support of vendors, service providers and others.
We expect whichever direction they take, they will move together because then roaming is much easier.
In this context, it's interesting that Paolini says it is likely that a new device will emerge. Cell phones and laptops are great, but neither is optimized to harness all the tremendous capabilities brought by wireless broadband.
but when you think about it, a laptop is a little too big to carry around all the time...most people just don't want to be bothered. On the other hand, a phone is a good device. Maybe a cellular phone has WiMax, but it is just an add-on that doesn't use the advantages of WiMax to the fullest extent. We need something in between, a data-centric device in a new form factor that allows you to capitalize on the advantages of mobile broadband. The other thing is to have consumer devices that have WiMax built in. It's a very good opportunity because the device is not likely to have a cellular interface.
The two points are connected. On one hand, she says the "ecosystem" - the intricate web of vendors, service providers, integrators and other assorted companies - will be influential in the relative success of WiMax, UMB and LTE.

On the other, she says a new type of device will be a deciding factor. Clearly, device makers, along with the companies that make the chips and other elements that are packed into them, are key members of any ecosystem. The immediate future of this sector would be easy to predict if one of the technologies was far superior to the others. This isn't so; it will be a confusing and hotly contested arena until one platform takes control. The key will be to follow the ecosystem.

Are You Still Hitting A Slice Even After Golf Instruction?

So the week is over and you and your group are finally at the first tee. And you are so glad you have a chance to play a round with your friends and just forget about work and all that goes with it.

It's a beautiful day. Sun is shining bright and warm, the sky is so blue it can't be real.

What a day!

You are up.

And as you get ready to tee off, you remember that your ball flight is left to right and so you must aim to the left to compensate. You think that maybe this time you won't slice the ball, but that thought quickly dissipates into the world of " not true" and reality sets itself firmly back into your mind. For you know that your slice will not disappoint you.

And so you take your backswing and wallop the damn thing out over the lake to the left, is it coming back ? Oh no .. you think, it's going straight... wait, no here it comes .. back to the right. Just like it always does. Into the far right rough, just where it always goes.

If you could just hit it a little more straight you would surely hit it a lot further.

You once again promise yourself that you will take that golf lesson from the pro next week.

One golf swing instruction should take care of that slice once and for all. That's what you may think.

So the round went well, you had fun and didn't play too bad.

The week went by fast and now you are going to do what you promised and take that golf lesson.

And here is what happens.

Your golf instructor tells you the following:

look you know that the slice occurs because of your downswing. But you have to be aware that all sorts of things have gone wrong before you even begin the backswing, let alone the downswing.

But if you want to get right to the actual movement that creates the spin on the ball that makes it go to the left and then to the right ... well it is referred to as an " over the top move"

This move happens when the clubhead comes from the top of your backswing to outside of your target line into the ball and continues on to the inside of your target line.

Now think about what I just said for a minute.

In most cases the clubface will be open and you will hit a glancing blow outside of the ball to inside of the ball. Kinda like a foul ball in baseball, where the bat only hits some of the baseball below it equator. Or on the bottom of the ball.

Sometimes the clubface is closed, in this case you hit it dead left, no slice, maybe a snap hook. Do not be encouraged by this. It is not a draw gone astray. The problems are exactly the same " hitting from the top"

Generally you will end up off balance, your weight will be more on the right side and your right shoulder will be higher than your left. This is also called hitting from the top because there normally is little if any weight shift in this move.

Have you ever seen the guy who swings and his left foot swings around on his finish, off the ground and it's a struggle for him to remain standing? All of his weight is on his right side?

The fact that the club is outside the target line and open will is unavoidable if you have an over the top swing.

The club is off plane and out of it's proper swing path. Neither is a good thing and tons of potential power is lost through this draining move.

In golf it would be a side swipe and you will bet some nasty spinning from this move. left to right.

In this golf instruction you will learn that most folks who suffer from the over the top move have similar grips. Wrong grips I might add.

In this golf lesson you will note that this wrong grip is always a weak one. left hand too far under the grip and the right hand too far on top of the grip. This grip tends to force an over the top move and it tends to prevent a release of the clubhead at impact or better stated it keeps the clubface open at impact.

Check you grip.. is it weak? If yes change it now to at least a neutral grip.

The clubhead must come down to your right side, not out and around the ball. Your right elbow can lead this first move to your right side. So... right elbow to your right side = first move

Use it as a mini drill .. half swing back with your new grip.. right elbow to the right side, hit the inside of the golf ball.

Roll a towel up.. lay it on the out side of the ball.. about 11/2 inches away parallel to the target line. lengthwise... now use the mini drill to hit balls .. do not hit the towel.. got it? Do not hit the towel.

Hit the inside of the golf ball and do not hit the towel and don't cheat.

This will help you get an inside swing path and prevent the over the top move.

One more time. Using your new grip, half back swing, right elbow to the right side first move, continue to push the clubhead toward the inside of the golf ball and do not hit the towel.

Gradually increase the length and speed of this move and soon you will no longer hit a slice and you will know why. Very important.

A Simple Golf Swing is a thing of beauty. You could actually have one too, have a look if you want more information about how to develop a consistent Simple Golf Swing and shoot in the 80's in 14 days or less: http://www.ebooksbestbuy.com/golf
