Bluetooth 5: The New Faster And Long Range Update Of Bluetooth 4.2

A new version of the Bluetooth wireless spec will be coming to devices soon, giving users faster connectivity among devices over longer distances.

The new version, Bluetooth 5, is a big upgrade over Bluetooth 4.2, the current specification. In a clear line of sight, the range of Bluetooth 5 could stretch to 400 meters, said analysts at The Linley Group in a research note this week. That means users could connect a smartphone to a Bluetooth speaker that may not even be visible.

Final Bluetooth 5 specifications will be disclosed by the end of this year or early next year, the Linley analysts said.

In a typical, realistic setting, Bluetooth 5 will offer a range of up to 120 meters, which is four times that of Bluetooth 4.2, and be two times faster, with data transfer rates of 2Mbps, said Chuck Sabin, director for business strategy at the Bluetooth-Special Interest Group, which sets the standards for Bluetooth.

Historically, once a final Bluetooth specification is released, devices quickly follow suit, Sabin said. So if the Bluetooth 5 specification is finalized and released late this year, devices that use it could come early next year, Sabin said.

Early versions of Bluetooth were used in audio equipment, headsets and cars. But Bluetooth has evolved; it's now central to the internet of things and is being used in smart home products, medical devices, drones, robots, smart meters and wearables. It is competing with wireless technologies like Wi-Fi and ZigBee.

The faster speed, longer range and error correction features in Bluetooth 5 will make it easier to push firmware to devices, Sabin said. That will be especially helpful for automobiles, smart meters and medical devices designed to be placed inside the body.

Bluetooth 5 will also have one-to-many messaging capabilities. For example, devices will be able to transmit data from a wearable to multiple devices. That capability will help in IoT, where a smart meter could transmit data to multiple computing and data sources.

Another improvement in Bluetooth 5 is the ability to broadcast richer data, including location information, URLs and multimedia files. For example, multiple sensors in a store could provide internal GPS-style navigation to a specific item. Bluetooth 5 could also be useful for self-driving cars, which have to communicate with many sensors and external sources like traffic lights.

Devices that support the latest Bluetooth and Bluetooth Low-Energy versions may be upgradeable to Bluetooth 5 via firmware. Otherwise, devices will require new chips and controllers, which are already being developed, Linley analysts said in the research note. For example, Texas Instruments' CC2640 wireless chip will support the Bluetooth 5 standard.

Reliance Jio MNP

If you want to keep your existing number and also want to experience Jio then you can now shift your existing number to Reliance Jio.


Reliance Chairman Mukesh Ambani dropped a proverbial bomb at the company's AGM on Thursday when we revealed all Reliance Jio plans will come with free voice calling, and data at a fraction of the cost offered by current telcos. Jio services will become available from Monday absolutely free as part of the 'Jio welcome offer', so everyone can try them at no charge. This Reliance Jio welcome offer will be valid till December 31, after which the announced rates will be applicable.
Free voice calling and lucrative data prices are sure to tempt many users to make the switch to Jio networks. Instead of getting a new number, you can opt for mobile number portability (MNP) to shift to the Reliance Jio network without changing your phone number. In July last year, DoT made it compulsory for telecom operators to roll out nationwide MNP, allowing users to keep their phone number even if they switched carriers or locations. Because of nation-wide MNP, subscribers of Airtel, Vodafone, Idea, and other telcos can shift to Reliance Jio and avail the free Preview Offer till end of the year without changing their number.

Here's how you can use MNP to shift to Reliance Jio without changing your number:

First up, you need to send a text message to your current operator requesting for a port out. The message PORT should be sent to 1900. In return, you will receive a Unique Porting Code from 1901 with 15 days validity from your current carrier.
Head to any Reliance Mobile Store or retailer and fill up the Customer Application Form (CAF) where you'll also fill in the porting code. Submit the required documents (proof of address, proof of identity and photograph), and in return Reliance will issue a new Reliance Jio SIM card. Once activated, this SIM will use the same phone number you already had, and your old SIM will be deactivated.



The Reliance Jio SIM could take up to 7 days to activate, and a fee of Rs. 19 will be charged. During porting, your number might  be dead for about two hours (sometime between 10pm and 5am) before the new Reliance Jio SIM gets activated. Once your current SIM starts showing "No Service", it's likely time to put in your new Reliance Jio SIM.
Once ported, the Jio SIM should be activated, and remember you cannot use MNP to go back to your earlier operator or someone else for at least 90 days. In his AGM speech, Ambani requested all the other operators to not limit customers' right to migrate to Jio using MNP.


He also blamed the telcos of creating a poor experience for Jio customers. He said that in the last week alone Jio customers faced 5 crore call failures to other networks because of insufficient interconnect capacity provided by competitors. Ambani claimed that the telcos were giving the impression to Jio customers that voice calling wasn't working, when actually the telco operators were deliberately dropping calls.
