In the year 2020, at CES, the Bluetooth SIG introduced the latest Bluetooth version, version 5.2. This announcement was presented alongside the statement of the next generation of Bluetooth audio, named: LE Audio.
It has been a while that Bluetooth has been inbuilt in electronic devices. The latest Bluetooth version that is released recently is Bluetooth 5.2.
We all are aware that Bluetooth is for exchanging data between devices without tangling wires, have you ever thought about what actually is Bluetooth Technology? How is it impacting the digital gadgets around the world? In the present day, if anyone gives you a laptop or phone without Bluetooth, how would you feel?
The idea for this article is to share information about the latest Bluetooth version and its advantages. Also, you will get an insight into electronic devices which come with Latest Bluetooth Technology.
Features of Latest Bluetooth Version 5.2
While December 6, 2016, marks the announcement of Bluetooth 5.0, still experts have been working on making technology more advanced and user-friendly, and faster for end-user.
With the rise of the new decade, Bluetooth Special Interest Group (SIG) published an advanced Bluetooth version known as Bluetooth LE Audio. Bluetooth Version 5.2 was issued on January 7, 2020.
With LE Audio, multiple devices will be capable of sharing data. The limit is two devices that can transfer music from a tablet, computer, or phone.
Humans with hearing difficulties will get a better audio experience.
The Technical specifications of the Latest Bluetooth Version 5.2 over Bluetooth is to add new features viz:
- Enhanced Attribute Protocol (EATT), an upgraded version of Attribute Protocol (ATT).
- LE Power Control
- LE Isochronous Channels.
Enhanced Attribute Protocol (EATT)
An upgraded version of ATT and enhancements to the Generic Attribute profile have been announced as Enhanced Attribute Protocol (EATT).
With the new protocol, end-user can experience a reduction in end-to-end latency and improvement in the responsiveness of applications.
EATT can be used over an encrypted connection only, so EATT has a security advantage over existing ATT.
LE Power Control
To optimize the used transmission power between connected devices, LE Power control plays a major role. Bluetooth LE receivers will now be able to monitor the signal’s strength and can dynamically request transmission power level changes so that there is always a trade-off for signal quality and low power use.
Some advantages of LE Power control are as follows:
- Decrease in power consumption by sources.
- Enhancements in the dependability of receiver signal.
- Developments related to the existing and upcoming wireless devices.
The Bluetooth controller can monitor and report path loss changes to the Bluetooth host using the concept of zones, which some application types will find useful. Benefits of the LE Power Control feature include:
- The reduction of overall power consumption by transmitters through dynamic power management conducted between connected devices.
- Improvements in reliability through the active maintenance of receiver signal strength so that it stays within the optimal range supported by the receiver.
- Improvements relating to coexistence with other wireless devices in the environment and using the 2.4 GHz frequency range. This benefit applies to all such devices, not just those that are using Bluetooth.
LE Isochronous Channels
With Low Energy Isochronous Channels, there will be an improvement in the sound quality of hearing aids. Connection and broadcasting of sound to multiple devices are possible only because of Isochronous Channels.
Also, the day is not far when we can have multi-language audio systems due to this technology.
On January 7, 2020, at CES 2020, Bluetooth Special Interest Group announced new specifications which might be coming within the Bluetooth world. The new set of features will be rolled out with the name LE Audio.
LE Audio may be made possible handiest after the feature of LE Isochronous Channels introduced in Bluetooth 5.2. This feature adds Isochronous data transport on the Bluetooth LE Radio.
LE stands for “Low Energy”. As the name suggests, LE will transmit data (sound) across devices on the low-energy spectrum. So, to maintain the quality of Bluetooth, it will use the new compression algorithm.
The new Wireless merchandise can be predicted to be designed with a discount in battery size which further reduces the overall product size.
The brand-new devices to be compatible with this new set of specifications might have playtime that is almost double the modern playtime.
LC3 – Low Complexity Communication Codec
- LE Audio is comprised of recent codec LC3. It is a low powerful and high-quality audio codec.
- Developers can have colossal flexibility, and they can design the new wireless merchandise with better audio high-quality and less power consumption.
With the new feature of LE Audio, the data will be transmitted between multiple synchronized devices which may be independent of each other.
This new feature will enhance Bluetooth-enabled devices to another level and demand innovation to a huge number of new merchandise.
Have you faced a situation that when your kid’s favorite song is getting played in the car and at the same time you receive a call on your mobile, which is also connected to a car stereo device through Bluetooth?
Now while you are on call, instead of music, you hear your baby’s crying voice because once your phone audio is connected, the music mutes completely, and your baby does not like that.
So, with the new multi Stream audio feature, audio from both will be heard simultaneously.
Improvement in Hearing Aid
With Bluetooth technology, a large number of people have been benefited. No doubt wireless calling has made driving safer.
People have become more productive as many people take calls while driving to home or office. The advantages can also be counted as more people are entertained.
The other set of people that will be benefited from the new feature of LE Audio are the ones using hearing aids.

Wi-Fi Latest 6: Features and Benifits
Wi-Fi is about to become faster. That is excellent information: faster internet is always in demand, significantly as we consume more bandwidth-demanding applications, video games, and videos with our laptop computers and also phones
The recent coming generation of Wi-Fi, referred to as Wi-Fi 6, is not just a simple speed-boosting or increasing the net speed. Its impact will undoubtedly be more nuanced, as well as we are likely to see its benefits more and more over time.
This is much less of a single-speed boost and even more of a future-facing upgrade created to ensure our speeds do not grind to a stop a couple of years later.
The next generation of Wi-Fi is called Wi-Fi 6. It will still do the same necessary thing– attach you to the net– only with many additional innovations to make that take place a lot more effectively, speeding up connections while doing so.
Wi-Fi 6 prepares to power completely brand-new mobile experiences today, supplying faster speeds for immersive-experience applications and more device and IoT capacity for high-density atmospheres such as university lecture halls and shopping centers, stadiums, and producing facilities.
Deal extra dependable Wi-Fi – A more regular as well as trustworthy network link gives a smooth experience for clients, IoT, and all applications, particularly voice and video.
Enhance your network ability – As wireless demands rise as well as consist of more IoT gadgets, Wi-Fi 6 (802.11 ax) manages even more data across the air passages than previous Wi-Fi standards. It also takes care of extra active customers per accessibility point
Increase speed, as well as transmission capacity – Wi-Fi 6, accomplishes speeds up to 4 times faster than previous Wi-Fi standards, improving the customer experience and efficiency of bandwidth-hungry applications like voice, video, as well as collaboration
Boost the 2.4-GHz band – The last upgrade for 2.4 GHz was one decade ago. Wi-Fi 6 brings brand-new improvements to the 2.4-GHz band that make your cordless work better with IoT gadgets that call for more powerful performance and better Wi-Fi coverage
The brand-new Wi-Fi 6 requirement is developed to address such issues with the guarantee to introduce a brand-new era of Wi-Fi. Wi-Fi 6 builds on the existing structure of its predecessors and likewise seeks to hold qualified companions to a boosted collection of requirements that consists of faster speed, larger capability, broader insurance coverage, as well as far better battery effectiveness.
The first thing to consider is that basic Wi-Fi technology performs its function using radio signals. To send a Wi-Fi transmission, devices have to modulate the frequency signal on a particular radio network, which will certainly then be obtained by the recipient tool in the form of binary code. Referred to as quadrature amplitude modulation (QAM), the procedure involves modulating radio waves in various methods to convey digital data, where the router’s act is determined by the range of binary code being sent.
Take a 2-QAM accessibility point as an instance. As it can modify the Wi-Fi radio waves in two habits, each transmission would wind up being a one-digit code (either a ‘1’ or a ‘0’). Its 4-QAM counterpart, in contrast, can send two-digit transmissions (‘ 00′, ’01’, ’10” or ’11”) with its capability to modulate waves in 4 distinctive means.
With Wi-Fi 6, however, the ante goes up. Clocking in at 1024-QAM allows devices to send 10-digit binary transmissions that boast speeds up to 25% and increase the throughput for intensive use cases. Set, the more binary codes a router can spread, the stronger and faster it. WiFi 6 1024 QAM: up to 2400 Mbps
QAM is not the only state to know – meet OFDMA, short for Orthogonal Frequency Division Multiple Access. A new feature is belonging to Wi-Fi 6 function on a divide-and-conquer principle, allowing devices to serve different clients at the same time within just one channel. This process is further enhanced with its additional ability to divide the transmission channel on the 2.5 GHz, and 5 GHz frequency bands into smaller digital entities called resource units (RUs).
Because Wi-Fi 6 allows multiple users to connect to the network all at once, there is a need to ensure that the timing for data transmissions remains as precise as possible across the board, too. For a more extensive network capacity, interference between simultaneous users has to be minimized, and Wi-Fi 6 manages to make this work through synchronizing the trigger frame broadcast of access points.
A trigger frame is, in simpler terms, a new framework adopted by Wi-Fi 6 to allocate RUs and set transmission timings for each client, such that upstream transmissions can be coordinated. As such, devices will be assigned to a specific individual transmit timing, the syncing of which brings about better bandwidth.
With Wi-Fi 6 also comes more sophisticated beamforming capabilities as well. In contrast to the traditional way of broadcasting Wi-Fi signals in all directions, beamforming focuses on projecting them in a particular direction, such that the signal is more potent and more concentrated. What this translates to is a longer range that results in better reception for devices, as well as fewer dead zones for increased coverage.
Last but not least, Wi-Fi 6 access points and routers will boast better battery efficiency. Courtesy of the new Target Wake Time (TWT) technology, devices are put on a schedule to receive data, giving them more time to stay engaged in sleep mode. This helps conserve battery life and reduces signal congestion and collision, both of which are convenient features in the Internet-of-Things (IoT) era, where constant connectivity is the way of life.
MAKES The Fastest Wi-Fi Speed Ever – Two key technologies are speeding up Wi-Fi 6 connections: MU-MIMO and OFDMA.
MU-MIMO, which stands for “multi-user, multiple inputs, multiple outputs,” is already in use in modern routers and devices, but Wi-Fi 6 upgrades it.
The technology allows a router to communicate with multiple devices simultaneously, rather than broadcasting to one device, and then the next, and the next. Right now, MU-MIMO allows routers to communicate with four devices at a time. Wi-Fi 6 will allow devices to communicate with up to eight.
The other new technology, OFDMA, which stands for “orthogonal frequency division multiple access,” allows one transmission to deliver data to multiple devices at once.
Instead of boosting the speed for individual devices, Wi-Fi 6 is all about improving the network when many devices are connected.
Wi-Fi 6 introduces some new technologies to help mitigate the issues that come with putting dozens of Wi-Fi devices on a single network. It lets routers communicate with more devices at once, lets routers send data to multiple devices in the same broadcast, and lets Wi-Fi devices schedule check-ins with the router. Together, those features should keep connections strong even as more and more devices start demanding data.
Devices Are More Likely to Maintain Fast Speeds on Busy Networks – The story starts to change as more and more devices get added to your network. Where current routers might start to get overwhelmed by requests from many devices, Wi-Fi 6 routers are designed to more effectively keep all those devices up to date with the data they need.
Each of those devices’ speeds won’t necessarily be faster than what they can reach today on a high-quality network, but they are more likely to maintain those top speeds even in busier environments
Those devices’ top speeds won’t necessarily be boosted, but the rates you see in typical, daily use likely will get an upgrade.
Exactly how fast that upgrade is will depend on how many devices are on your network and just how demanding those devices are.
Instead, new devices will start coming with Wi-Fi 6 by default. As you replace your phone, laptop, and game consoles over the next five years, you will bring home new ones that include the latest version of Wi-Fi.
There is one thing you will have to make a point of going out and buying, though: a new router. If your router doesn’t support Wi-Fi 6, you won’t see any benefits, no matter how many Wi-Fi 6 devices you bring home. (You could see an advantage, though, connecting Wi-Fi 5 gadgets to a Wi-Fi 6 router because the router may be capable of communicating with more devices at once.)
Again, this isn’t something worth rushing out and buying. But if your home is packed with Wi-Fi-connected smart devices, and things start to get sluggish in a couple of years, a Wi-Fi 6 router may be able to help meaningfully.
How can You get the latest WI-FI 6?
You will need to buy new devices. Gallon Electric Can help choose the right equipment. Our service team always presents for consulting on your requirements.
Wi-Fi generations rely on new hardware, not just software updates, so you will need to buy new phones, laptops, and so on to get the latest version of Wi-Fi.
To be clear: this is not something you will want to run out to the store and buy a new laptop to get. It is not that game-changing of an update for anyone’s device.
Latest Wi-Fi 6 and Battery or Power Source – Another new technology in Wi-Fi 6 allows devices to plan out communications with a router, reducing the amount of time they need to keep their antennas powered on to transmit and search for signals. That means less drain on batteries and improved battery life in turn.
This is all possible because of a feature called Target Wake Time, which lets routers schedule check-in times with devices.
It is not going to be helpful across the board, though. Your laptop needs constant internet access, so it is unlikely to make heavy use of this feature (except, perhaps, when it moves into a sleep state).
Last year, Wi-Fi started getting its most significant security update in a decade, with a new security protocol called WPA3. WPA3 makes it harder for hackers to crack passwords by constantly guessing them, and it makes some data less useful even if hackers manage to obtain it.
Current devices and routers can support WPA3, but it is optional. For a Wi-Fi 6 device to receive certification from the Wi-Fi Alliance, WPA3 is required, so most Wi-Fi 6 devices are likely to include the more robust security once the certification program launches.
Devices supporting Wi-Fi 6 are just starting to trickle out. You can already buy Wi-Fi 6 routers, but so far, they are expensive high-end devices. A handful of laptops include the new generation of Wi-Fi, too, but it is not widespread just yet.
The inclusion of Wi-Fi 6 is likely to become even more expected next year. The Wi-Fi Alliance will launch its Wi-Fi 6 certification program this fall, which guarantees compatibility across Wi-Fi devices. Devices don’t need to pass that certification, but its launch will signify that the industry is ready for Wi-Fi 6’s arrival.
Innovation and performance in challenging environments
The ubiquity of Wi-Fi and its ability to complement other wireless technologies helps bring the promise of connecting everyone and everything, everywhere, closer to reality. Wi-Fi popularity has also created very diverse and densely populated Wi-Fi conditions, requiring technological advances to meet users’ needs. Wi-Fi CERTIFIED 6 delivers improvements and new features that enable Wi-Fi devices to operate efficiently in the densest and dynamic connectivity settings.
- Orthogonal frequency division multiple access (OFDMA) effectively shares channels to increase network efficiency and lower latency for both uplink and downlink traffic in high demand environments
- Multi-user numerous inputs, multiple outputs (multi-user MIMO) allows more downlink data to be transferred at one time, enabling access points (APs) to handle more devices concurrently
- 160 MHz channel utilization capability increases bandwidth to deliver more excellent performance with low latency
- Target wake time (TWT) significantly improves network efficiency and device battery life, including IoT devices
- 1024 quadrature amplitude modulation mode (1024-QAM) increases throughput for emerging, bandwidth-intensive uses by encoding more data in the same amount of spectrum
- Transmit beamforming enables higher data rates at a given range to increase network capacity
Wi-Fi CERTIFIED 6 devices bring enhanced performance to emerging applications such as virtual and augmented reality in e-Learning, telepresence, and healthcare. Wi-Fi CERTIFIED 6 also provides carriers and public Wi-Fi operators with more capabilities to support advanced connectivity in retail, stadiums, and transportation hubs, including a growing array of location-based applications and service
Bluetooth and Wi-Fi are both wireless technologies for connecting your devices, but they are quite different. While Wi-Fi is mainly used to connect your devices to the internet, Bluetooth is only used to connect your devices to each other. The main difference between Bluetooth and Wi-Fi is the purpose behind its design. Bluetooth is essentially used to connect short-range devices for sharing data, while Wi-Fi provides high-speed internet access. Another difference between Bluetooth and Wi-Fi is that a limited number of devices have provision to connect with other Bluetooth devices. On the other hand, Wi-Fi provides access to more significant users.
Bluetooth is used when speed is not our concern, and low bandwidth is allocated to it. Wi-Fi provides high bandwidth as the speed of the internet is an essential factor. Although both are wireless communication forms, Bluetooth and Wi-Fi differ in terms of their purpose, capabilities, and other factors. Bluetooth allows for short-range data transfer between devices.
When is it better to use a Bluetooth-enabled vs. a smart device? Find out what separates Bluetooth from Wi-Fi, and which one is better for you.
Bluetooth and Wi-Fi are different standards for wireless communication. Bluetooth technology is useful when transferring information between two or more devices that are near each other when speed is not an issue, such as telephones, printers, modems, and headsets. It is best suited to low-bandwidth applications like transferring sound data with telephones (i.e., with a Bluetooth headset) or byte data with hand-held computers (transferring files) or keyboard and mice.
Wi-Fi is better suited for operating full-scale networks because it enables a faster connection, better range from the base station, and better wireless security (if appropriately configured) than Bluetooth.
When it time to consider Hardware accessibility, Bluetooth adaptor on all the devices connecting Wireless adaptors on all the instruments of the network, a wireless router, and wireless access points
Bluetooth and Wi-Fi are not the same things, though they do sometimes serve similar functions. The main difference between the two technologies is that Bluetooth does not require internet access, while Wi-Fi does.
To choose what you need, Bluetooth v5.2 or the latest Wi-Fi 6 be subject to what you are irritating to do. For quick file transfers or sharing data between two devices, Bluetooth is best. However, Wi-Fi has a broader range, so you can connect devices that are further apart. Bluetooth devices do not require an internet connection, so they use zero data. If you have a data allowance, you can use Bluetooth without worrying about paying overage fees. Wi-Fi does not use data either.
For security issues, Both Bluetooth and Wi-Fi are vulnerable to hackers. However, Wi-Fi tends to be a more critical target due to the sensitive data that is often transmitted via Wi-Fi connections.
