Bluetooth technology

As a pre reading activity for this text which belongs to an English basic course to Electrical Engineering students, whose main aim is reading-comprehension, I would give them a WORDLE for them to guess the meaning of the main words of the text to read:

Find in the WORDLE one word which has the closest meaning to:
 modernization/novelty - Global - eternal/infinite - supporter - invulnerability - Happening at the same time- Distant - without connecting cables

1 Bluetooth wireless technology is a worldwide specification for a small-form factor, low-cost radio solution that provides links between mobile computers, mobile phones, other portable handheld devices, and connectivity to the Internet. The specification is developed, published and promoted by the Bluetooth Special Interest Group (SIG).
2 Bluetooth wire technology revolutionizes the personal connectivity market by providing freedom from wired connections – enabling links between mobile computers, mobile phones, portable handheld devices, and connectivity to the Internet. Bluetooth technology redefines the very way we experience connectivity.
3 While the possibilities are nearly endless for the use of the technology, some of the current capabilities include:
eliminating the need for wired connections between electronic products and accessories , exchanging files, business cards, calendar appointments, etc. with groups of Bluetooth users , transfering and synchronizing files between devices, connecting to localized content services in public areas , functioning as remote controls, keys, tickets and e-cash wallets
4 Establishing a standard means integrating well-tested technology with the power-efficiency and low-cost of a compliant radio system. Establishing a standard also means a group of industry leading promoter companies who drive the specification forward (Bluetooth SIG). Bluetooth technology works because it has been developed as a cross industry solution that marries a vision of engineering innovation with an understanding of business and consumer expectations.
5 Bluetooth wireless technology is unique in its breadth of applications. Links can be established between groups of products simultaneously or between individual products and the Internet. This flexibility, combined with strict interoperability requirements, has led to support for Bluetooth wireless technology from a wide range of market segments, including software developers, silicon vendors, peripheral and camera manufacturers, mobile PC manufacturers and handheld device developers, consumer electronics manufacturers, car manufacturers, and test and measurement equipment manufacturers.
6The Bluetooth wireless specification defines a low-power, low-cost technology that provides a standardized platform for eliminating cables between mobile devices and facilitating connections between products. Unlike many other wireless standards, the Bluetooth wireless specification includes both link layer and application layer definitions for product developers.
7 Radios that comply with the Bluetooth wireless specification operate in the unlicensed, 2.4 GHz radio spectrum ensuring communication compatibility worldwide. These radios use a spread spectrum, frequency hopping, full-duplex signal at up to 1600 hops/sec. The signal hops among 79 frequencies at 1 MHz intervals to give a high degree of interference immunity. While point-to-point connections are supported, the specification allows up to seven simultaneous connections to be established and maintained by a single radio.
8 Synchronizing the capabilities of the telecommunications, computing, and networking industries Bluetooth SIG members understand innovation and the business of innovation. The Bluetooth SIG provides a forum for companies to work together using short-range wireless technologies to solve customer problems. Companies can join either as Associate or Adopting . The Bluetooth SIG promoters include 3Com, Agere, Ericsson, IBM, Intel, Microsoft, Motorola, Nokia and Toshiba, and hundreds of Associate and Adopter member companies.

 WHILE READING: A. Answer True/False
 1. All wireless standards include both link layer and application layer definitions for product developers.
 2. The Bluetooth technology provides a standardized platform for connection between mobile electronic devices without using cables.
