Spectrum is for telecommunication what fuel is for aviation. Spectrum is a range of electromagnetic frequencies or airwaves which are used by the telecom companies for establishing a connection between a cell tower and a mobile phone. The bandwidth of this spectrum is directly proportional to the speed of a wireless data network since more data can be transmitted simultaneously through a broader data pipeline whereas the frequency is inversely proportional to the coverage since lower frequencies penetrate better through physical barriers and thus have wider coverage.

The spectrum holding data sheet embedded in this article represents the current spectrum holdings of all active telecom operators across all frequency bands across all 22 telecom circles along with their liberalisation status and expiry dates Spectrum is allotted for a period of 20 years.

All figures represented are in MHz. There is a spectrum cap which dictates how much spectrum a particular operator can hold in a circle in a particular band. Apart from auctions, operators can buy or sell spectrum usage rights from each other which is called spectrum trading.

Operators may also sign a spectrum sharing agreement to share their spectrum holdings to achieve a pooled spectrum holding with more bandwidth. Only intra-band spectrum sharing is permitted where both operators need to hold spectrum in the same band in a given circle, inter-band spectrum leasing is not allowed. Note: We update this chart in realtime to ensure it is always up to date with the latest changes in spectrum holding. Thank you for reading OnlyTech!

By now, if you are following the smartphone news, you will know that Google Pixel 4 and the Google Pixel 4 XL will not be launched in India. The two phones were unveiled on October 15 at an event in New York and while the previous Pixel phones were launched in India, the Pixel 4 and the Pixel 4 XL will not be brought here by Google because they use 60GHz frequency for some of their functionality.

This technology is currently regulated in India and cannot be used for civilian and commercial purposes. Well, it will work but with reduced functionality. Earlier, we had heard from sources in Google that the Pixel 4 and the Pixel 4 XL would work as intended and with their full functionality in India if someone bought them from the US or a similar market.

This means, we learnt, that a Pixel 4 bought in the US would have the functionality related to Soli radar, which used 60GHz, working in India. But apparently that preliminary information was, well, preliminary.

Now that the phones have been launched, there is better clarity around the availability of the Soli functionality. Now we hear that Google is disabling the Soli functionality on the basis of location. This means even if you have a Pixel 4 bought in the US, running the software available for the US region, the Soli radar functionality will be disabled through software if the phone is brought to India.

Once you take the phone out of India, the Soli functionality should work again. Google says that Soli radar powers the Motion Sense feature in the Pixel 4.

It can sense when you're reaching for the phone and will initiate face unlock, or turn off your screen when you're not around. New Quick Gestures let you skip songs when you don't want to pick up your phone.

Just wave your hand to snooze alarms, dismiss timers, or silence your phone ringer," notes the company.

In fine print, Google highlights that the Motion Sense is "not functional in Japan and may not be functional in other Pixel countries. But the two high-end smartphones are not coming to India.

Now, we learn that if you buy them outside and bring them to India, some of their features will not work here. The two phones will not come to India because they use Soli radar, a technology that makes use of 60GHz frequency. The 60GHz mmWave frequency cannot be used in India for civilian purposes due to government regulations.

Latest Stories Is this a man or an animal running into snow?IEEE The microwave section of the radio spectrum has a number of major advantages. It is possible to use a very wide bandwidth to enable high throughput data, and also good re-use of the spectrum is possible. As signals do not travel over such great distances and are absorbed by buildings, etc, high levels of re-use can be obtained without users on the same channel experiencing interference.

As part of the marketing, the scheme will be known by the name WiGig after the Wireless Gigabit Alliance that endorses the system, but it is also sometimes referred to as 60GHz WiFi. To promote and advance the use of microwave Wi-Fi an alliance called the Wireless Gigabit Alliance was set up. Working with the IEEE, both organisations are committed to the advancement of the standard.

It has been standardised as IEEE This provides industry standardisation, industry recognition, input from industry to ensure that the standard is realisable and also meets the industry needs, and it also provides an easy marketing name. The Wireless Gigabit Alliance was formed to provide a single multi-gigabit wireless communications standard among consumer electronics, handheld devices and PCs, and drives industry convergence using unlicensed ISM industrial, scientific and medical 60 GHz spectrum.

It is anticipated that as microwave technology becomes cheaper and the requirement for spectrum increases, WiGig technology will become widespread in its use. In addition to the tabulated details, the system uses a MAC layer standard that is shared with current In this way, seamless transition can occur between the systems. However the Dependent upon geography these are located between 57 GHz and 66GHz.

It can therefore be seen that only channel 2 with its centre frequency of This is recommended to be the default channel. The fact that only four channels are available is not seen as a problem because signal absorption is high in this region and even with high re-use, signals are unlikely to interfere. The signal spectrum and spectral mask needs to ensure that the signal is maintained within a certain bandwidth.

The spectral mask shows the mask for the spectrum. One of the main forms of modulation used is OFDM.The ISM radio bands are portions of the radio spectrum reserved internationally for industrial, scientific and medical ISM purposes other than telecommunications. The powerful emissions of these devices can create electromagnetic interference and disrupt radio communication using the same frequencyso these devices are limited to certain bands of frequencies.

In general, communications equipment operating in these bands must tolerate any interference generated by ISM applications, and users have no regulatory protection from ISM device operation. Despite the intent of the original allocations, in recent years the fastest-growing use of these bands has been for short-range, low power wireless communications systems, since these bands are often approved for such devices which can be used without a government license, as would otherwise be required for transmitters; ISM frequencies are often chosen for this purpose as they already have interference issues.

Cordless phonesBluetooth devices, near field communication NFC devices, garage door openersbaby monitors and wireless computer networks Wi-Fi may all use the ISM frequencies, although these low power transmitters are not considered to be ISM devices. Individual countries' use of the bands designated in these sections may differ due to variations in national radio regulations.

Because communication devices using the ISM bands must tolerate any interference from ISM equipment, unlicensed operations are typically permitted to use these bands, since unlicensed operation typically needs to be tolerant of interference from other devices anyway.

The ISM bands share allocations with unlicensed and licensed operations; however, due to the high likelihood of harmful interference, licensed use of the bands is typically low. In order to improve harmonisation in spectrum utilisation, the majority of service-allocations stipulated in this document were incorporated in national Tables of Frequency Allocations and Utilisations which is within the responsibility of the appropriate national administration.

The allocation might be primary, secondary, exclusive, and shared. Type A footnote 5. The use of these frequency bands for ISM applications shall be subject to special authorization by the administration concerned, in agreement with other administrations whose radiocommunication services might be affected.

In applying this provision, administrations shall have due regard to the latest relevant ITU-R Recommendations. Type B footnote 5. Radiocommunication services operating within these bands must accept harmful interference which may be caused by these applications. Radio communication services of these countries operating within this band must accept harmful interference which may be caused by these applications.

The band The American delegation specifically proposed several bands, including the now commonplace 2. The report of the August 9th meeting of the Allocation of Frequencies committee [6] includes the remark:. There was therefore some point in attempting to reach world agreement on this subject. Radio frequencies in the ISM bands have been used for communication purposes, although such devices may experience interference from non-communication sources.

In the U. Many other countries later developed similar regulations, enabling use of this technology. It was part of a broader proposal to allow civil use of spread spectrum technology and was opposed at the time by mainstream equipment manufacturers and many radio system operators. Industrial, scientific and medical ISM applications of radio frequency energy short: ISM applications are — according to article 1.

The original ISM specifications envisioned that the bands would be used primarily for noncommunication purposes, such as heating. The bands are still widely used for these purposes. For many people, the most commonly encountered ISM device is the home microwave oven operating at 2.The Indian government does not allow the use of the 60GHz frequency by civilian entities. This frequency is essential for the Soli radar chip to be functional.

Realizing this, the company has decided not to launch the new models in the Indian market. Even as the news filtered in of Google deciding to hold back the launch of the Google Pixel 4 and 4 XL in the Indian market, many fans of the company and its hardware were upset. They posted many messages online. Some felt the company should have known this and found a way to get around it. There were however others who had different takes on this.

One view says even if Google had launched these phones, they would not have been able to register decent sale numbers mainly due to the price factor. Even Apple has started making its iPhones locally now. From that perspective, the decision really may not hurt Google much. One of the suggestions doing the rounds is that Google could make some modifications and add a fingerprint sensor on the Google Pixel 4a and 4a XL.

There is the aspect of the Soli radar being present in the phone but not functional. That is for Google to look into. Again, this is just a one-off suggestion. The technology giant may find other ways if it is keen to see its latest hardware used in India. This is largest market in the world for mobile phones after China and it would be odd to remain out of it. Your email address will not be published. Headline News.

Samsung Plans for a Under Display Front Camera; Galaxy Fold 2 Could be the First Device Samsung Electronics keeps working on new technologies and it has created many subsidiaries and research establishments to implement….Most people are unaware of the multiple benefits we get from the growing number of short-range devices SRDs in our lives.

An SRD is a radio-frequency transmitter device used in telecommunication to transmit information without harmful interference to other radio equipment. Technological developments in radio—wideband and UWB, medical diagnostics, RFID, usage, telemetry and radar—led to the surge in applications that can leverage and use SRDs in multiple fields.

Some of the common applications of SRDs in day-to-day life include telecommand, telemetry, voice and video applications, wireless audio applications, railway applications, road transport and traffic telematics, alarms, inductive applications, radio microphones, RF identification systems, ultra-low power active medical implant, among many others.

It is now time to accelerate adoption and detail specifics in terms of spectrum, power levels, and possible applications to enable industry and users to work hand-in-hand and bring it to the market. For this, we need the 60Hz band that has 7GHz of bandwidth and offers unmatched capacity compared with lower frequency spectrum, which sets it apart from other high frequency bands.

Multiple oxygen-absorption lines merge to form a single, broad absorption band. The high oxygen absorption reduces the need for active spectrum management. High oxygen attenuation and narrow beams reduce interference between links, making it particularly suited for the uncoordinated operation. The high bandwidth allows for wide channels and enables high throughputs.

60ghz frequency india

These characteristics render the band unsuitable for traditional multi-kilometre fixed links, but suitable for higher capacity, lower-coverage applications. So, operating effectively in higher bands requires more devices at short ranges. This makes it essential to combine the two.

The spectrum band in the GHz is attractive for high capacity transmissions over short distances. As lower-frequency bands are cramped, higher frequencies are more suitable for SRD applications. The large bandwidth allows for wide channelisation e. The combination of the 60GHz spectrum and SRDs will create an explosion of applications; it will enable new technology and business model opportunities for a variety of established and emerging ecosystem players. It will enhance the value of wireline infrastructure and help improve the performance of cellular services.

The availability of delicensed spectrum helps support the provision of affordable services to new geographies and populations, and help in expansion of services into un-served and underserved communities. The role of regulators and policymakers is pivotal; else, there is a risk of market fragmentation and the appearance of uncoordinated categories.

In a dense environment, many links are expected to operate in close proximity. Because of the high rate of oxygen absorption and corresponding signal attenuation, regulators are moving forward with a license-exempt framework for the V-band. This has triggered technology innovation and ecosystem growth.

This process is similar to the global Wi-Fi story, where the use of unlicensed 2. This will allow technology developers and connectivity providers to deliver high-speed backbone services at very low cost and enable the proliferation of affordable broadband across India.

Devices must adhere to respective regulatory compliance standards. The accompanying graphic gives a consolidated view of different countries.

Applications listed are derived from ITU and other standardisation bodies. Let us look at two examples of industry innovations in SRDs that show us how the industry is gearing up to meet the requirements of the various applications by developing the right hardware and software. This is an integrated single-chip sensor capable of operation in the 60 to 64GHz band. It enables unprecedented levels of integration in an extremely small form factor.

The device is an ideal solution for low power, self-monitored, ultra-accurate radar systems in the industrial space.

The second example is RF transceivers from a microelectronics company made in the unlicensed 60GHz band that offers new opportunities for short-range contactless connectivity by enabling unprecedented multi-Gigabit data rates.
