Using USB, Ethernet, Bluetooth, ExpressCard pcmcia and PC card. Established in 1984, Brainboxes the leading Serial communication and Data Acquisition device. Serialio offers Great Software, Great Products, and even better customer service. I will not hesitate to recommend Serialio and their SerialMagic software to my. In order to use Bluetooth technology, a device must be compatible with the subset of Bluetooth profiles often called services necessary to use the desired services. Bluetooth Frequently Asked Questions Bluetooth Technology. Frequently Asked Questions. General Answers Q What is Bluetooth A Bluetooth is the name for a short range radio frequency RF technology that operates at 2. GHz and is capable of transmitting voice and data. The effective range of Bluetooth devices is 3. Bluetooth transfers data at the rate of 1 Mbps, which is from three to eight times the average speed of parallel and serial ports, respectively. Q Why is the technology called Bluetooth A The heart of the Bluetooth brand identity is the name, which refers to the Danish king Harald Bluetooth Blaatand who unified Denmark and Norway. In the beginning of the Bluetooth wireless technology era, Bluetooth was aimed at unifying the telecom and computing industries. Q How is Bluetooth used A Bluetooth can be used to wirelessly synchronize and transfer data among devices. Bluetooth can be thought of as a cable replacement technology. Typical uses include automatically synchronizing contact and calendar information among desktop, notebook and palmtop computers without connecting cables. Bluetooth can also be used to access a network or the Internet with a notebook computer by connecting wirelessly to a cellular phone. Q What is the future direction of the Bluetooth standard A At this time, we anticipate the Bluetooth SIG to evolve the Bluetooth technology to provide greater bandwidth and distances, thus increasing the potential platforms and applications used in the emerging personal area networking marketplacelt top Q Where can I find more information on BluetoothA The following web sites are useful Bluetooth resources www. Technology Answers Q How secure is a Bluetooth network A Bluetooth is extremely secure in that it employs several layers of data encryption and user authentication measures. Bluetooth devices use a combination of the Personal Identification Number PIN and a Bluetooth address to identify other Bluetooth devices. Cours Calculs Commerciaux Pdf more. Data encryption i. Bluetooth security. The transmission scheme. FHSS provides another level of security in itself. Instead of transmitting over one frequency within the 2. GHz band, Bluetooth radios use a fast frequency hopping spread spectrum. FHSS technique, allowing only synchronized receivers to access the transmitted data. Q What is Frequency Hopping Spread Spectrum. FHSS A Frequency Hopping Spread Spectrum FHSS is a spread spectrum modulation scheme that uses a narrowband carrier that changes frequency in a pattern known to both transmitter and receiver. Properly synchronized, they maintain a single logical channel. To an unintended receiver, FHSS appears as short duration impulse noise. More simply, the data is broken down into packets and transmitted to the receiver of other devices over numerous hop frequencies 7. Only transmitters and receivers that are synchronized on the same hop frequency pattern will have access to the transmitted data. The transmitter switches hop frequencies 1,6. Q Will other RF Radio Frequency devices interfere with Bluetooth DevicesA No. Bluetooth radios operate on the unlicensed 2. GHz Industrial, Scientific and Medical frequency band that is shared among other devices microwave ovens, cordless phones, garage door openers, etc. Bluetooth radios switch frequencies at such a rapid pace 1,6. RF sources is highly unlikely. Bluetooth is a robust communication system. Q Will Bluetooth and Wireless LAN WLAN interfere with each other A No, both Bluetooth and WLAN can co exist. Since Bluetooth devices use Frequency Hopping and most WLANs use Direct Sequence Spreading techniques they each appear as background noise to the other and should not cause any perceivable performance issues. Q What is the data throughput speed of a Bluetooth connection A Bluetooth transfers data at a rate of 7. Kbps, which is from three to eight times the average speed of parallel and serial ports, respectively. This bandwidth is capable of transmitting voice, data, video and still images. Q What is the range of Bluetooth transmitterreceivers A Bluetooth is designed for very low power use, and the transmission range will only be 1. High powered Bluetooth devices will enable ranges up to 1. Considering the design philosophy behind Bluetooth, even the 1. Bluetooth is intended for. Later versions of the Bluetooth spec may allow longer ranges. Q What kind of encryption will be used for Bluetooth security A The Bluetooth specification 1. LFSR linear feedback shift registers. The sum of the width of the LFSRs is 1. This arrangement allows Bluetooth to be used in countries with regulations limiting encryption strength, and facilitate a future upgrade path for the security without the need for a costly redesign of the algorithms and encryption hardware according to the Bluetooth specification. Key generation and authentication seems to be using the 8 round SAFER encryption algorithm. The information available suggests that Bluetooth security will be adequate for most purposes but users with higher security requirements will need to employ stronger algorithms to ensure the security of their data. Q Is Bluetooth practical for use with mobile devices A Yes. One concern for mobile computing users is power consumption. Bluetooth radios are very low power, drawing as little as 0. A in standby mode and 3. A during sustained data transmissions. Bluetooth radios alternate among power saving modes in which device activity is lowered to maximize the mobile power supply. Q What is a Personal Area Network PAN A A Personal Area Network is another name for a Bluetooth Piconet. Q What is. Home. RF  A Home. RFlike Bluetooth is a specification for connectivity and mobility in a home like environment. Home. RF Working Group has developed a specification for wireless communications in the home called the Shared Wireless Access Protocol SWAP. Regulatory Market Answers Q Are different brands of Bluetooth products compatibleA Yes. They have to. The Bluetooth Logo Certification Program requires Bluetooth products to interoperate with products manufactured by other vendors those products that dont interoperate will not be allowed to use the Bluetooth logo. Q Can Bluetooth products be used on aircraft A The Federal Aviation Administration FAA and other aviation regulatory bodies worldwide are currently reviewing the use of Bluetooth products on private and commercial aircraft. In the U. S. the FAA is the governing body to grant approval for Bluetooth product use on aircraft therefore, we must defer to their impending ruling. Q What companies are involved in the Bluetooth initiative A Global technology leaders Ericsson, Nokia, IBM, Intel and Toshiba founded the Bluetooth SIG in 1. Dxwnd Ms Site. These companies are now supported by over 1,0. Widcomm, Inc. lt top Q What types of companies are likely to adopt or promote Bluetooth technology A Companies likely to adopt this technology include, but are not limited to, software developers, network vendors, silicon vendors, peripheral and camera manufacturers, mobile PC and handheld device manufacturers, consumer electronics manufacturers and more. Q Are there any patents or licenses involved A Yes, there are several patents on different parts of the technology. Scale Software driver Serial port RS2. USB download. You Dont need a Pay.
