Technical Information about Bluetooth

What you are about to read isn’t exactly what you would expect from something entitled Technical Information about Bluetooth. There will be information regarding Bluetooth technology, but not solely technical information regarding it, nor “highly” technical information regarding it.

Bluetooth technology is basically the now standard when talking about wireless connections. Technical information would indicate that it utilizes a low power radio frequency in doing so. Bluetooth is now the buzzword when wireless connections are concerned.

Through Bluetooth technology, Bluetooth equipped Digital Cameras could easily transfer pictures wirelessly, to other Bluetooth enabled devices, like personal computers, regardless if these are laptops or desktop computer systems. Bluetooth equipped printers could easily print wirelessly, utilizing Bluetooth technology, ultimately negating the need for wires for such printers to successfully operate.

These examples not only illustrate the wireless nature of Bluetooth technology, but its universal capacity to deal with various Bluetooth connections, regardless of the device class the technology is built into.

Universal and wireless. That is Bluetooth. Here is a short rundown of certain technical information about Bluetooth.

The short range, low power radio frequency used by Bluetooth technology, is, established by international agreements, a frequency dedicated for Scientific, Industrial and Medical Devices. Bluetooth technology operates on an unlicensed 2.45 gigahertz frequency, which is in truth something between the 2.402 gigahertz to the 2.480 gigahertz frequency band. Wireless connections with Bluetooth technology is established through the generation of a Personal Area Network, or PAN, and features various security protocols, as well as connectivity data streams, and other technical information.

The Bluetooth name comes from a poetic source, as well as the Bluetooth logo which the technology has become associated with.

King Harald Bluetooth of Denmark and Norway is where the technology takes its name from. King Harald Bluetooth reigned during the late tenth century, and his most notable achievement as King is that he had united the many warring tribes in Denmark, symbolizing the universal connectivity capacity of Bluetooth technology. The modern Latin H and the letter B which basically combines the Bluetooth logo, hails from the Nordic runes Berkanan and Haglaz, defining the bind rune.

Among the more popular of Bluetooth enabled devices are Bluetooth headsets for mobile phones and Bluetooth Adapters, or Bluetooth Dongles.

Bluetooth headsets for mobile phones are basically wireless versions of mobile phones’ Hands Free Kits, truly making the “free” in Hands Free Kits come to life by simply being wireless. Bluetooth Adapters, or Bluetooth Dongles are USB devices which give computers access to Bluetooth technology. They are add-on hardware devices which make non-Bluetooth integrated computer systems, capable of Bluetooth wireless connections.

So there you have it. The “technical information” regarding Bluetooth technology.

The Elements of the Physical Layer of Bluetooth

The physical layer of Bluetooth has several elements starting with the radio frequency. Bluetooth operates in a 2400 - 2483.5 MHz bandwidth, which is the open ISM band (ISM stands for (Industrial, Scientific and Medical). This bandwidth allows it to maximize compatibility of communication worldwide and in fact, the global usage of the ISM spectrum is the key reason why the designers of Bluetooth chose it.

Modulation is another element of the Bluetooth physical layer, which employs “Gaussian Frequency Shift Keying” or GFSK. The index of modulation index is restricted to 0.28 to 0.35, which corresponds to a maximum deviation in frequency of 140 kHz to 175 kHz.

The Bluetooth physical layer also consists of the use of a technique known as Frequency Hopping Spread Spectrum or FHSS, which enables a Bluetooth device to hop from one radio frequency onto another at an incredible speed of up to 1600 hops per second. Bluetooth uses 79 different channels. It is through Frequency Hopping Spread Spectrum that multiple Bluetooth devices do not interfere with each other’s transmissions.

Transmission Power is another aspect of the physical layer of Bluetooth and there are three classes that the technology supports: Class 3 with a 1 milliwatt power and a typical 10 meter range; Class 2 with a 2.5 milliwatt power and a typical 20 meter range and Class 1 with 100 milliwatt power and a 100 meter typical range. In actuality, almost all types of Bluetooth devices support just one of the power classes, Class 3, which is the lowest.

The physical layer is also made up of the link data rate also with the maximum rate supported being 723.2 kb per second and speech coding, which ensures that the quality of speech is acceptable.

These elements come together to make Bluetooth technology work. During any typical Bluetooth operation, two or more devices share a radio channel that is in-sync to one clock and FHSS pattern. One device, the master, serves as the reference point of the synchronization and the rest of the devices in the group are referred to as slaves. This synchronized setup is known as a “piconet”, which is the fundamental mode of communication of Bluetooth technology.

The physical channel of Bluetooth has subdivisions consisting of slots or units of time. Transmission of data happens between devices in the packets that are placed in these time units/slots. The frequency hopping pattern occurs in between the packet’s sending and receiving of data. Each slave is physically linked to the master device but there are no physical links between slaves.

For in-depth study of Bluetooth technology, you can refer to the Bluetooth official website or to other websites dedicated to wireless technologies. There are many online tutorials that you can download to learn more about how this amazing technology works.

Information on Bluetooth Specifications

The wireless technology, better known as Bluetooth, has been around for several years already but for a lot of people it is just another “high-tech” word.

In spite of the Bluetooth’s existence, many people still have little to no understanding of this technology and its applications. You can read information on Bluetooth on different magazines and articles or see it in advertisements but one usually has a vague idea about how it really works.

Bluetooth Technology works by transmitting radio waves or signals from an electronic device to another. Usually, the transmission of signals ranges approximately 30 feet or more depending on the Bluetooth specifications. Included in the different Bluetooth specifications of the latest devices is the capability to transmit signals of up to 100 feet.
 
The Bluetooth wireless technology is very much similar to how a computer is connected to other devices using a cable like a monitor, keyboard, mouse and printer or an mp3 player to a headphone.

What is good about using a Bluetooth device is that you no longer have to worry about connecting cables. To have a better understanding of this technology, you should know about the different Bluetooth specifications.

Here are some Bluetooth specifications from the Bluetooth Special Interest Group (SIG):

• The channel of Bluetooth devices in a piconet has 1 Mbps total capacity. Information on handshaking and headers use 20 percent of its total capacity.

• Frequencies in different countries:

1. United States and Europe’s frequency is 2,400 to 2,800 MHz with 79 1-MHz RF channels
2. Japan’s frequency is 2,472 to 2,497 MHz with 23 1-MHz RF channels

• Channel jumps randomly between 79 or 23 RF channels for about 1,600 time a second
• Every channel is sectioned in time slots about 625 microseconds in duration 
• The master in a piconet sends signals in seven time slots while its slaves transmits signals in irregular time slots
• A packet’s width can be as much as five time slots and every data can range up to 2,745 bits long
• Synchronous Connection Oriented (SCO) and Asynchronous Connectionless (ACL) are the two types of data transfer
• Three SCO links that have 64,000 Bps are present in a piconet
• A master can hold up three SCO with one or two slaves
• Slots that are not held in reserve for SCO links can be utilized for ACL links
• A master and a slave can contain one ACL link
• ACL can be either point-to-point meaning master to a slave or transmit to all the slaves
• Slaves in an ACL link can only transmit when the master requests for it

These are the different Bluetooth specifications used in the latest methods of wireless technology. The Bluetooth technology is standardized and for sure it will be around for quite a long time.

Information on How Frequency Hopping Spread Spectrum Works

Frequency hopping spread spectrum is one of the two basic modulation methods in signal transmission. It works by switching the frequencies repeatedly while transmitting signals often to lessen the efficiency of electronic warfare through telecommunication interference. Frequency hopping spread spectrum is also known as FH- CDMA or frequency hopping code division multiple access.

Frequency hopping spread spectrum has become very common in modulation techniques these days. Basically, this modulation method allows signals to be sent out across a band that is wider than the required information signal bandwidth. The signals that are originally from a narrowband are transmitted to different frequency bands on a wider spectrum. This promotes privacy, lesser narrowband obstruction and improved signal capacity.

In frequency hopping spread spectrum, the transmitter skips between frequencies according to a planned or random algorithm. Transmitter functions in accordance with a receiver that is kept tuned to the same frequency that the transmitter uses. Data is sent on a narrowband and afterwards, the transmitter adjusts to another frequency and will transmit signals again. The receiver can skip frequencies on a specified bandwidth multiple times per second making the frequency hopping spread spectrum need a wider bandwidth to transmit information using a single carrier frequency.

The alternative to frequency hopping spread spectrum works by cutting the data into small parts and the sends them across a frequency. This spread spectrum is called DS-CDMA or direct sequence code division multiple access. Frequency hopping spread spectrum devices are less expensive but the devices that DS-CDMA uses are more reliable. The advantage of frequency hopping spread spectrum depends on the availability of access points along the same area which is not possible with DS-CDMA.

Rules are administered over the use of frequency hopping spread spectrum. For instance, in North America, the ISM (Industrial Scientific Medial) waveband is sectioned into 75 channels with transmission power not greater than 1 watt per channel. This limit ensures that one device will not eat excessive bandwidth or stay too long on one frequency. 

The FCC or Federal Communications Commission has modified its policy to allow the frequency hopping spread spectrum systems in the 2.4 GHz frequency band. This is to permit the use of wider bandwidths to enable the operation of Internet devices at higher speed rates for the development of wireless local are networks and cable modems.
  
The frequency hopping spread spectrum was originally discovered by a movie actress named Hedy Lamarr along with her pianist during World War II. It was discovered by using a piano to manipulate the hopping of frequency and was foreseen as a way to communicate during the war. Frequency hopping spread spectrum was patented under Hedy Lamarr and her pianist although they never made a penny out of it.

Different Bluetooth GPS Accessories

The idea of using your PDA as a GPS or Global Positioning System device is common and in fact, there are numerous GPS accessories available on the market for this purpose.  However, up until recently, these GPS units made use of a CompactFlash card slot or a wired configuration to hook up to the handheld unit. Some attach the PDA through a bulky apparatus. Oftentimes, the GPS unit itself is bulky and adds to the weight of a PDA not to mention ruins its compact and sleek design.

Today, thanks to the wireless technology known as Bluetooth, one can easily transform a PDA into a handheld GPS device that is fully-functional without the need for cables, expansion slots and other unsightly accessories. Set the GPS receiver somewhere with a clear sky view while holding or mounting the PDA for greater screen visibility and quick menu access.
