The wireless era.

Wireless communication (or just wireless, when the context allows) is the electromagnetic transfer of information between two or more points that are not connected by an electrical conductor. The most common wireless technologies use radio waves.                                                                                                                                                                    With radio waves, intended distances can be short, such as a few meters for Bluetooth or as far as millions of kilometers for deep-space radio communications. It encompasses various types of fixed, mobile, and portable applications, including two-way radios, cellular telephones, personal digital assistants (PDAs), and wireless networking. Other examples of applications of radio wireless technology include GPS units, garage door openers, wireless computer mouse, keyboards and headsets, headphones, radio receivers, satellite television, broadcast television and cordless telephones. Somewhat less common methods of achieving wireless communications include the use of other electromagnetic wireless technologies, such as light, magnetic, or electric fields or the use of sound.

                           The term wireless has been used twice in communications history, with slightly different meaning. It was initially used from about 1890 for the first radio transmitting and receiving technology, as in wireless telegraphy, until the new word radio replaced it around 1920. Radios in the UK that were not portable continued to be referred to as wireless sets into the 1960s. The term was revived in the 1980s and 1990s mainly to distinguish digital devices that communicate without wires, such as the examples listed in the previous paragraph, from those that require wires or cables. This became its primary usage in the 2000s, due to the advent of technologies such as mobile broadband, Wi-Fi and Bluetooth.

  Wireless operations permit services, such as mobile and interplanetary communications, that are impossible or impractical to implement with the use of wires. The term is commonly used in the telecommunications industry to refer to telecommunications systems (e.g. radio transmitters and receivers, remote controls, etc.) which use some form of energy (e.g. radio waves, acoustic energy,) to transfer information without the use of wires.[1][2][3] Information is transferred in this manner over both short and long distances.

Power MOSFETs, which are used in RF power amplifiers to boost radio frequency (RF) signals in long-distance wireless networks.

The wireless revolution began in the 1990s, with the advent of digital wireless networks leading to a social revolution, and a paradigm shift from wired to wireless technology, including the proliferation of commercial wireless technologies such as cell phones, mobile telephony, pagers, wireless computer networks, cellular networks, the wireless Internet, and laptop and handheld computers with wireless connections. The wireless revolution has been driven by advances in radio frequency (RF) and microwave engineering, and the transition from analog to digital RF technology, which enabled a substantial increase in voice traffic along with the delivery of digital data such as text messaging, images and streaming media.

The core component of this revolution is the MOSFET (metal-oxide-semiconductor field-effect transistor, or MOS

transistor).  Power MOSFETs such as LDMOS (lateral-diffused MOS) are used in RF power amplifiers to boost RF signals to a level that enables long-distance wireless network access for consumers, while RF CMOS (radio frequency CMOS) circuits are used in radio transceivers to transmit and receive wireless signals at low cost and with low power consumption.The MOSFET is the basic building block of modern wireless networks, including mobile networks such as 2G, 3G, 4G and 5G. Most of the essential elements in modern wireless networks are built from MOSFETs, including the base station modules, routers, RF circuits, radio transceivers, transmitters, and RF power amplifiers. MOSFET scaling is also the primary factor behind rapidly increasing wireless network bandwidth, which has been doubling every 18 months, as noted by Edholm’s law.

The MOSFET was invented by Mohamed Atalla and Dawon Kahng at Bell Labs in 1959. Its very large-scale integration (VLSI) capability led to wide adoption for digital integrated circuit chips by the early 1970s, but it was initially not the most effective transistor for analog RF technology where the older bipolar junction transistor (BJT) remained dominant up until the 1980s. A gradual shift began with the emergence of power MOSFETs, which are discrete MOS power devices designed for power electronic applications, including the vertical power MOSFET by Hitachi in 1969, the VDMOS (vertical-diffused MOS) by John Moll’s research team at HP Labs in 1977, and the LDMOS by Hitachi in 1977. MOSFETs began to be used for RF applications in the 1970s.RF CMOS, which are RF circuits that use mixed-signal (digital and analog) MOS integrated circuit technology and are fabricated using the CMOS process, was later developed by Asad Abidi at UCLA in the late 1980s.


By the early 1990s, the MOSFET had replaced the BJT as the core component of RF technology, leading to a revolution in wireless technology. There was a rapid growth of the wireless telecommunications industry towards the end of the 20th century, primarily due to the introduction of digital signal processing in wireless communications, driven by the development of low-cost, very large-scale integration (VLSI) RF CMOS technology. Power MOSFET devices, particularly the LDMOS, also became the standard RF power amplifier technology, which led to the development and proliferation of digital wireless networks.

RF CMOS integrated circuits enabled sophisticated, low-cost and portable end-user terminals, and gave rise to small, low-cost, low-power and portable units for a wide range of wireless communication systems. This enabled “anytime, anywhere” communication and helped bring about the wireless revolution, leading to the rapid growth of the wireless industry. RF CMOS is used in the radio transceivers of all modern wireless networking devices and mobile phones, and is widely used to transmit and receive wireless signals in a variety of applications, such as satellite technology (e.g. GPS), bluetooth, Wi-Fi, near-field communication (NFC), mobile networks (e.g. 3G and 4G), terrestrial broadcast,

and automotive radar applications, among other uses.


In recent years, an important contribution to the growth of wireless communication networks has been interference alignment, which was discovered by Syed Ali Jafar at the University of California, Irvine. According to Paul Horn, this has “revolutionized our understanding of the capacity limits of wireless networks” and “demonstrated the astounding result that each user in a wireless network can access half of the spectrum without interference from other users, regardless of how many users are sharing the spectrum.

As we all know when driving we should not have any distraction or by the phone.  We should not take calls while driving.

That is why it is advisable to use bluetooth ear.
