Bluetooth Replacement From Nokia?

[Analog Kid]

What is the differences and advantages between wibree, wibro, and wimax?

WiBro and WiMAX are essentially the same-- long range (kilometers) wireless broadband. WiMAX is the global standard under development that's apparently getting picked up by Sprint in the US and others elsewhere to provide "4G" wireless services. Depending on how they use the spectrum they'll get T1 speeds. WiBro is the Korean variant that follows a similar design but was deployed before the WiMAX forum settled on a final standard.

You don't want WiMAX in a watch unless you're willing to carry a very large battery on your wrist.

Wibree is a low data rate, short range, ultra-low power wireless link for peripherals like sensors, keyboards and mice.

Have you read the article? They are working with the Bluetooth group... This is simply another protocol that is lower speed, lower power, but can reuse much of the same hardware used in Bluetooth to save cost. It's not a headset replacement, it's for talking to sensors and ultra low power, low data rate devices. Think pulse sensors, or watch interfaces.

Thanks smarty. I commented before the update was made.

Thanks smarty.

Anytime I can be helpful and be praised for my intelligence is a good day...

The article title is misleading though-- this isn't being billed as a BT replacement, even by Nokia. It's complementary.

Close, but no banana:

Haha ... here is some more info...

Harald Bluetooth, son of Denmark's first king, Gorm the Old, from whom the present Danish queen, Margarethe II, traces direct descent, did not have blue teeth. Instead, the name refers to a great man with a dark complexion. The Danish word for blue, blå, also meant dark and the words for man, mand, and tooth, tand, sound much the same. Harald Bluetooth is credited with Christianizing Denmark, Norway, and parts of Sweden and with uniting the countries into one kingdom. At the time of his rule, somewhere between 940 and 980 AD, southern Sweden was part of Denmark. In southern Sweden is the city of Lund, which is where Ericsson developed the Bluetooth technology. According to Ericsson in its discussion of Harald Bluetooth (http://bluetooth.ericsson.se/bluetoothf/beginnersg/default.asp?page=2), "One of his skills was to make people talk to each other....," hence the choice of Bluetooth to name this communications standard. If you're ever in Jelling, Denmark, you can view the rune stone Harald Bluetooth raised in honor of his parents. There's another, vastly newer, rune stone dedicated to Bluetooth himself. It's outside Ericsson's Mobile Communications office in Lund.

Note: link above is dead its VERY old previous to 2001. Gives ya an idea of how long BT has been around and its uphill battle against analysts and self claimed gurus' saying WiFi was going to kill it. yeah right. I was going by memory in my earlier post.

Today, many people carry numerous portable devices, such as laptops, mobile phones, PDAs and mp3 players, for use in their professional and private lives. For the most part, these devices are used separately—that is, their applications do not interact. Imagine, however, if they could interact directly: participants at a meeting could share documents or presentations; business cards would automatically find their way into the address register on a laptop and the number register on a mobile phone; as commuters exit a train, their laptops could remain online; likewise, incoming e-mail could now be diverted to their PDAs; finally, as they enter the office, all communication could automatically be routed through the wireless corporate campus network.

These examples of spontaneous, ad hoc wireless communication between devices might be loosely defined as a scheme, often referred to as ad hoc networking, which allows devices to establish communication, anytime and anywhere without the aid of a central infrastructure. Actually, ad hoc networking as such is not new, but the setting, usage and players are. In the past, the notion of ad hoc networks was often associated with communication on combat fields and at the site of a disaster area; now, as novel technologies such as Bluetooth materialize, the scenario of ad hoc networking is likely to change, as is its importance. In this article, the authors describe the concept of ad hoc networking by giving its background and presenting some of the technical challenges it poses. The authors also point out some of the applications that can be envisioned for ad hoc networking.

For almost EVERYTHING to know how was bluetooth implemented in the beginning before knowing how its evolved today ... read this PDF... http://www.ericsson.com/ericsson/corpinfo/publications/review/2000_04/files/2000046.pdf

Will it be safer than bluetooth? That would be most important to me, less radiation exposure.

You cannot be serious?! Do you realize this arguement has been proven DEAD for quite some time now? BT radio's even at at Class 1 (100Meters) dont even generate 1 degree celcius temparature change in less than 1 mm deep of human flesh at a range of less than 5cm's away.

I'm digging on WHERE I found that source I believe its on Ericsson's site.

How is the Bluetooth technology licensed? Are there patents or licenses involved? Is this technology royalty-free?

While there are many patents on different parts of the technology, the Bluetooth wireless specification plans to remain a royalty-free specification. As a member of the Bluetooth SIG, you will need to execute several agreements to enjoy these benefits.

Bluetooth SIG Members

The Bluetooth SIG has over 4,000 member companies developing, manufacturing, and selling thousands of Bluetooth enabled products worldwide. Because Bluetooth wireless technology is an open platform, all members of the Bluetooth SIG have permission to use Bluetooth wireless technology in their products and services. There are three levels of membership with unique benefits: Promoter, Associate, and Adopter.

I knew wibro is kinda of big korean and so is wimax as many devices have that option. But thank you for making sense of it, but one question. Will wimax be the next wifi technology and wibro be like the next cell technology(similar to evdo, edge, umts, and so on)?
