However, the two-“o” “Google” we’re familiar with today is the result of an accidental misspelling by one of Page’s classmates, Sean Anderson. Cofounder, and current sad CEO Larry Page decided that it would be the perfect name for his new company as it reflected the nearly unimaginable vastness the Web. Implementers should be aware that the maximum transmit power level permitted under a given set of regulations might not be the same for all modulation modes.The word googol (note the third “o” and the lack of an “e”) is a mathematical term for the number 10 to the 100th power (or a 1 followed by 100 zeros). * Devices shall not exceed the maximum allowed transmit power levels set by the regulatory bodies that have jurisdiction over the locales in which the device is to be sold or intended to operate. (3 advertising channels/37 data channels) Initially supporting simple presence and proximity capabilities, Bluetooth LE now supports Bluetooth ® Direction Finding and soon, high-accuracy distance measurement.Ģ.4GHz ISM Band (2.402 – 2.480 GHz Utilized)
While initially known for its device communications capabilities, Bluetooth LE is now also widely used as a device positioning technology to address the increasing demand for high accuracy indoor location services. Bluetooth LE supports multiple communication topologies, expanding from point-to-point to broadcast and, most recently, mesh, enabling Bluetooth technology to support the creation of reliable, large-scale device networks. Transmitting data over 40 channels in the 2.4GHz unlicensed ISM frequency band, the Bluetooth LE radio provides developers a tremendous amount of flexibility to build products that meet the unique connectivity requirements of their market. The Bluetooth Low Energy (LE) radio is designed for very low power operation.
The Bluetooth Classic radio also enables data transfer applications, including mobile printing. Supporting point-to-point device communication, Bluetooth Classic is mainly used to enable wireless audio streaming and has become the standard radio protocol behind wireless speakers, headphones, and in-car entertainment systems.
The Bluetooth Classic radio, also referred to as Bluetooth Basic Rate/Enhanced Data Rate (BR/EDR), is a low power radio that streams data over 79 channels in the 2.4GHz unlicensed industrial, scientific, and medical (ISM) frequency band.
