Bluetooth
Bluetooth is a wireless technology standard for exchanging data over short distances using short-wavelength UHF radio waves in the industrial, scientific and medical radio bands. It allows for connection between devices like computers, phones, keyboards, printers, headsets within a range of about 10 meters. Bluetooth operates using a frequency-hopping spread spectrum in the 2.4 GHz band to avoid interference and jamming. Up to eight devices can be connected in a piconet, with one device acting as the master and up to seven acting as slaves. Multiple piconets can be further connected to form a scatternet, allowing for many more than eight devices to be connected together. Bluetooth is commonly used for hands-free calling, file

It (bluetoth)
Bluetooth is a wireless technology developed in 1994 by Ericsson to allow electronic devices to communicate wirelessly within short ranges of up to 30 feet. It eliminates the need for cables and adapters between devices. The Bluetooth Special Interest Group was formed to develop the technology further. Bluetooth devices include headsets, printers, cameras, and more. It has advantages like low power consumption and cost but disadvantages like lower data rates, limited range, and security issues compared to WiFi.
Bluetooth smart technology(description about all versions)
Bluetooth technology was developed in 1994 by Ericsson in Sweden to eliminate the need for proprietary cable connections between devices. It uses short-range radio transmissions to allow wireless connections between nearby electronic devices like phones, computers, and other devices. The Bluetooth Special Interest Group was formed in 1998 to develop specifications so that Bluetooth devices from different manufacturers can interoperate. Bluetooth technology is now widely used to wirelessly connect a variety of consumer and industrial devices over short distances.
Bluetooth Technology
Bluetooth is a wireless technology standard for exchanging data over short distances. It was developed in 1994 to replace wired cables connecting devices. Bluetooth allows devices such as phones, headphones, mice and keyboards to connect without cables by forming small local networks called piconets. Each piconet connects up to seven active devices and one master device, using frequency hopping to avoid interference. Multiple piconets can connect to form scatternets, allowing communication between different piconets. Bluetooth operates in the unlicensed 2.4 GHz radio band and has a range of 10-100 meters.
Bluetooth Technology
Bluetooth is a wireless technology that allows devices to connect and exchange data over short distances without wires. It was created in 1994 by the Swedish company Ericsson and standardized by the Bluetooth Special Interest Group in 1998. Bluetooth works using low-power wireless signals within a range of about 30 feet. It allows devices like mobile phones, headphones, computers and more to connect and share data like audio, contacts, and files without needing to be physically plugged together. Some common types of Bluetooth devices include dongles and headsets. While Bluetooth enables wireless connectivity, its disadvantages include a limited range and higher battery usage than wired connections.
Bluetooth
Bluetooth is a wireless technology standard that allows for the exchange of data over short distances without wires. It was developed in 1994 by Ericsson as a cable replacement technology and was designed to be inexpensive, wireless, and easy to use. Bluetooth can connect various devices like mice, keyboards, and printers and allows devices to share data and form personal area networks within a range of about 100 meters. It uses a frequency-hopping spread spectrum to reduce interference and improve security. Bluetooth devices are organized into piconets of up to 8 devices that maintain wireless connections. Multiple independent piconets form scatternets that allow devices to move between different piconets.
Bluetooth ppt
Bluetooth is a wireless technology that allows electronic devices to connect and exchange information over short distances without wires. It was invented in 1994 by Ericsson to replace cables between devices and enhance mobility. Bluetooth works using radio waves to transmit data between devices within around 30 feet of each other. It has become an important wireless standard and is used in many devices like headphones, speakers, printers, and more. While Bluetooth enables cable-free connectivity, it also has limitations like slower speeds than WiFi and potential security issues if not properly encrypted. Overall, Bluetooth continues to be improved and adopted in more applications due to fulfilling the basic need of short-range wireless connectivity.
Bluetooth
Bluetooth is a wireless technology standard used for exchanging data over short distances. It was developed in the late 1990s by telecom vendor Ericsson and was intended to replace cables connecting devices like mobile phones, laptops, and other electronics. Bluetooth operates in the unlicensed 2.4 GHz band and supports data rates up to 720 Kbps. Common uses of Bluetooth technology include connecting headphones, keyboards, and mice to devices without cables.

Bluetooth
Bluetooth is a short-range wireless technology developed for exchanging data over short distances, primarily designed to support simple wireless networking of devices and peripherals. It uses radio waves to transmit data up to around 30 feet and creates small networks (piconets) of up to 8 devices connected to a central device. While Bluetooth uses the same 2.4GHz frequency range as WiFi, it has slower speeds, shorter range, and supports fewer connected devices, making it better suited for uses like connecting phones and wireless controllers rather than replacing WiFi. Future devices are expected to increasingly incorporate Bluetooth connectivity.
Bluetooth
Bluetooth was invented in 1994 by Ericsson to replace wired cables for data transfer between electronic devices using short-range radio links. It allows inexpensive wireless connection of multiple devices without direct line of sight. Bluetooth devices can form piconets of one master device connected to up to seven slave devices or scatternets of multiple interconnected piconets for longer range communication. While convenient, Bluetooth has disadvantages like increased security risks and limited range.

Climate Impact of Software Testing at Nordic Testing Days
My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.
