2M is expert in wired and wireless connected products. In many of our wearable devices Bluetooth Low Energy is used but we also use standard Bluetooth or other wireless technologies (LORA, WIFI, NFC) depending on the application.
Wireless Bluetooth wearable devices
Wireless Bluetooth wearable devices can be extremely low power. So no battery recharges.
Easy data exchange with mobile devices
Bluetooth LE allows for direct data transfer from wearable sensor device to mobile phone. Store data first or directly stream live data. All is possible. BLE is supported on iOS from the iPhone 4S onwards. Alle newer iPhones and iPADS are BLE enabled. Android embraced the Bluetooth Low Energy technology a little later, but now most new Android phones also support Bluetooth Low Energy.
Standardized wireless technology
Bluetooth Low Energy products represent a quantum leap for Bluetooth technology, allowing billions of previously disconnected devices to join the connected world with very low power consumption.
What is Bluetooth technology?
Bluetooth® technology is the global wireless standard enabling, convenient, secure connectivity for an expanding range of devices and services. It is an essential element for bringing everyday objects into the connected world. Created by Ericsson in 1994, Bluetooth wireless technology was originally conceived as a wireless alternative to RS-232 data cables. Bluetooth technology exchanges data over short distances using radio transmissions. Bluetooth technology operates in the unlicensed industrial, scientific and medical (ISM) band at 2.4 to 2.485 GHz, using a spread spectrum, frequency hopping, full-duplex signal at a nominal rate of 1600 hops/sec. The 2.4 GHz ISM band is available and unlicensed in most countries.
What is Bluetooth Low Energy used for?
Bluetooth wireless technology is built into billions of products, from cars and mobile phones to medical devices and computers and even forks and toothbrushes. Bluetooth technology allows you to share voice, data, music, photos, videos and other information wirelessly between paired devices.
What else can Bluetooth technology do?
Originally intended to be a wireless replacement for cables on phones, headsets, keyboards and mice, Bluetooth technology now goes way beyond that. Bluetooth technology is bringing everyday devices into a digital and connected world. In the health and fitness market, the use cases vary widely — from sensors that monitor activity levels to medical and wellness devices that monitor healthcare, like a glucometer, inhaler or toothbrush. The top-selling Smartphones, PCs and tablets all support Bluetooth technology. In-vehicle systems give the ability to make phone calls, send texts, and even make dinner reservations. The Bluetooth SIG is also seeing developments where drivers will monitor important information like vehicle diagnostics, traffic, even driver health — all in real time. Bluetooth technology is creating opportunities for companies to develop solutions that make a consumer’s life better.
Range is application specific and although a minimum range is mandated by the Core Specification, there is not a limit and manufacturers can tune their implementation to support the use case they are enabling. Range may vary depending on class of radio used in an implementation:
- Class 3 radios – have a range of up to 1 meter or 3 feet
- Class 2 radios – most commonly found in mobile devices – have a range of 10 meters or 33 feet
- Class 1 radios – used primarily in industrial use cases – have a range of 100 meters or 300 feet
