What's the latest Bluetooth version

This new wireless technology can be used in various devices with low energy consumption, in contrast to the previous bluetooth specifications. The adoption of Bluetooth 4.0 devices will enable improvements that include minimum energy usage levels, average idle (static) mode power consumption, and the ability to function for years on standard coin-cell batteries. Energy-saving devices in question include watches, pedometers, measuring devices, or other technological devices (gadgets) that use coin-sized batteries. In addition, the use of Bluetooth 4.0 is relatively affordable, can be operated by multi-vendors, and has a wider range. Bluetooth 4.0 has specifications for energy-efficient consumption to be able to transfer data in a short distance.

This technology is an enhancement to the capabilities of Bluetooth 3.0, the previous generation of Bluetooth, which was launched in April 2009. Currently, Bluetooth 4.0 is considered the most suitable technology to be used as a medium for transferring short-range communication networks, even though it has no less big competitors from wireless technology companies such as WiBro, UWB (ultra wide band), and WiFi. In May 1998, several promoter companies consisting of Ericsson, IBM, Intel, Nokia and Toshiba were affiliated and formed a group called the Special Interest Group (SIG) which then began to manufacture a specification called Bluetooth. The Bluetooth 1.0 specification document as the first generation was launched in July 1999. Then, in December of the same year, the creation of the Bluetooth 2.0 specification document was started again with the addition of four new promoters, including 3Com, Lucent Technologies, Microsoft and Motorola. Bluetooth 3. 0 then emerged as a new generation of wireless communication that requires low power and has 8 times the speed of the previous generation. The new specification Bluetooth 3.0 can use the option with an additional antenna, and the speed reaches 24 Mbps with an average speed of 22 Mbps. Finally, in early 2010, Bluetooth 4.0 technology was introduced in order to meet the demands of wireless technology targeting low energy applications, particularly in the health, fitness, shopping center security, and home entertainment industries. In other words, Bluetooth 4.0 technology is a form of Bluetooth evolution that prioritizes the use of energy-efficient wireless technology.

Longer usage time up to years by using only small capacity batteries (coin cell batteries).

Currently, more than 1800 companies in various fields, including in semiconductor manufacturing, automotive companies, and airlines have joined a consortium as adopters of bluetooth technology. These companies include Compaq, Xircom, Phillips, Texas Instruments, Sony, BMW, Puma, NEC, Casio, Boeing, and others. Now, the Bluetooth SIG standard is indeed held by the promoter group. Less power consumption so it saves battery or electricity. Longer usage time up to years by using only small capacity batteries (coin cell batteries). Low production costs. Longer distance. Able to reach more than 100 meters. Transfer speed is better with around 1 Mbps capability. The security system is more controlled than the security system in previous generations of bluetooth. Bluetooth 4.0 technology improves the main specifications of Bluetooth so that it allows two types of implementation, namely single-mode and dual-mode. HS, while single mode chips rely on a high degree of integration.

This enables the embedding of bluetooth on compact devices thus enabling the transfer of data from one device to many devices (point-to-multipoint) with advanced power saving and guaranteed data transfer security even though the costs incurred are minimal. Bluetooth 4.0 technology supports the transmission of very short data packets; a minimum of 8 octets and a maximum of 27 octets transmitted at a speed of 1 Mbps. Bluetooth 4.0 technology uses frequency hopping modulation that is adaptive to all versions of Bluetooth. The purpose of using frequency hopping is to minimize the occurrence of interference with all technologies that work on the 2.4 GHz ISM Band frequency. The efficiency of a multi-path system will benefit from increasing the link budget. Bluetooth 4 technology. 0 places a significant number of controllers so that the service provider (host) can have a longer sleep-period and work only when needed.

Bluetooth 4.0 technology uses a 32-bit access address in each data packet.

This will provide significant savings because it can be assumed that the host uses high power consumption compared to the data transfer traffic controller. Bluetooth 4.0 technology has the ability to support connection provision and data transfer up to 3 milliseconds. This value is a very short time so that when needed, Bluetooth 4.0 can immediately disconnect again after the transfer process takes place. The increased modulation index in Bluetooth 4.0 enables it to provide an energy range of up to 100 meters. Energy-efficient Bluetooth 4.0 technology uses 24 bit CRC in each package to ensure this technology is safe against possible interference. Bluetooth 4 technology. 0 uses Full AES-128 CCM encryption which is the latest encryption of data packets so that their use is more secure than the previous generation Bluetooth technology. Bluetooth 4.0 technology uses a 32-bit access address in each data packet. Thus, billions of devices can be connected with Bluetooth 4.0. This technology uses a very optimal one-to-one connection. In addition, this energy-efficient technology also supports one-to-many connections using the Star Topology. When using fast connection or disconnection, data can be moved in a topology such as a link. Angus Robinson, Anritsu PA 2000). On Your Marks for Testing Bluetooth, Test & Measurement Words.

Are you planning to buy an automatic car? Or planning to ride it in the near future? Maybe you already know that the way to drive an automatic car is different from the usual car, which shifts the gears manually. Automatic cars have automatic transmissions, where the automatic car gearshift system is designed to be able to move without having to step on the clutch pedal. Automatic transmission has two types of systems, both of which are also known to be simpler and easier, namely semi-automatic and automatic systems. This is How to Check Jakarta Number Plates, Easy! Even though it's automatic, it doesn't mean that driving an automatic type car is just playing the gas and brakes. You also have to be required to have a good feeling in measuring engine power because automatic cars also have transmissions that you can adjust depending on your needs. You will meet the automatic transmission lever with the code P, R, N, D, D3, 2 and L. If you are a new player in driving an automatic car, you are definitely confused by the letters and numbers that are rarely found. 9 Ways to Get Rid of Stickers on Motorcycles, Smooth Back Again! How to Check Vehicle Number Plate Owners Online, Easy! Complete Car Window Film Price List, Must Know! Well, to help you recognize a dead car gear, Qoala will explain in full about automatic car gear, from how to drive it, the meaning and function of each of the codes above and other information you need to drive an automatic car through this review.
