Companies that already use Wimax or will use Wimax

Some of you keep saying Att, Verizon, etc are going LTE... So what! What matters is the number of 3rd party companies (non cell carriers) who already back and use Wimax. At last count there are 513 companies on board with Wimax. Most companies that use wireless transmission (ex. banks, govt, etc) for their business use CDMA technology, CDMA is compatible with Wimax. CDMA is NOT compatible with LTE.

Here is a link which shows the companies on board with Wimax, keep in mind not every company is listed:

Also, many of these companies are in other countries where Wimax is live!

Scorpio, its nice to see someone else stoked about this technology. I have had an interest in both WiMax and LTE for the last year and a half and have tried to learn as much as I can in my spare time. I can't wait for the deployment. this is a huge major step in the wireless industry. this will change the way people conduct everyday business and I am happy that Sprint is first to the line.

After researching info on Wimax I can't understand why Verizon preliminarily wants to go with LTE. Especially since LTE is not planned for rural areas. Here is some more info:

In practical terms, WiMAX would operate similar to WiFi but at higher speeds, over greater distances and for a greater number of users. WiMAX could potentially erase the suburban and rural blackout areas that currently have no broadband Internet access because phone and cable companies have not yet run the necessary wires to those remote locations.

A WiMAX system consists of two parts:

* A WiMAX tower, similar in concept to a cell-phone tower - A single WiMAX tower can provide coverage to a very large area -- as big as 3,000 square miles (~8,0

As much as I am pro WiMax and Clearwire/Sprint, I feel like its only right that people know that while the technology is capable of covering 3,000 square miles, test markets so far show it to be consistently reliable within 30 miles of a tower, up to 100 with line Of Sight (LOS). Throw a tree or building in there and youre back down to 30 miles. They say the lower frequencies carry farther, with better building penetration, and Sprint is using one of the higher end frequencies that support WiMax, so maybe that could be the reason for that small shortcoming. Eh?

The trade off is equal for lower frequencies. half as much load capacity. this will slow data transfer considerbly during heavy traffic usage. but 2.5ghz will penetrate buildings. just not as easily.

Since when is CDMA compatible with WiMax? They are in two completely different families of standards. The natural evolution path for CDMA is UMB, however, most CDMA carriers have chosen to use LTE instead.

In fact, Motorola developed a chipset that can make seamless handoffs between CDMA2000 1xEV-DO Rev.A and LTE. I don't think any CDMA/WiMAX chipsets have been developed yet.

Check your facts before you provide an opinion, click the link:

Your article says NOTHING about it being able to make seamless handoffs between WiMax and CDMA. While it supports both technologies in the same device, it cannot make seamless handoffs between the two technologies.

You: "I don't think any CDMA/WiMAX chipsets have been developed yet."

Those chips were developed years ago, my cousin works for Samsung US, he went to the Mobile WiMax Summit 2006 in South Korea, the SPH P9000 was demoed.

This device does have seamless transfer! A similar Samsung device will be available on the Sprint Wimax network next year.

WiMax and CDMA are NOT compatible, go ask anyone with solid understanding of wireless tech. Having a device supporting both does not mean they are compatible. Having handoff between them does not mean they are compatible either. Your understanding of compatibility is not "compatible" to the wireless industry.

Does the chipset in the forthcoming Samsung phone automatically connect the CDMA and WiMax backbones? It's quite amazing to have a single phone that fully connects two national networks to a single backbone?

Or are you saying Samsung isn't going full speed with WiMax and is falling back on older technologies such as CDMA to look into the future...

I am so stoked for WiMax. why wait for LTE when i can have this technology very soon. I want to enjoy the benefits sooner rather than later. Wife locked the keys in the car? no problem. the phone will unlock it. She forgot to set the alarm in the house again? good thing I could verify it and also set it through my phone...Don't ever marry a blond! She forgot to set the timer on the oven. What?! No dinner?! that F'n Bitch! wait. "uhh.. yes honey, no problem I can do it from my phone. have fun with the girls". "yeah whatever.love you too" NOT!
Damn Boss! he sucks and this job F'n sucks. now I'm not going to be home in time for that movie on cable. I'll just set the DVR from my phone or better yet, watch it from my phone with my Boss's secret...
