SKYLAB（天工测控）will talk something about Bluetooth Module PCB Antenna.

Bluetooth is a very familiar application when people use mobile phones many years ago. However, have you ever heard of Bluetooth Low Energy? This is one of the most popular features in recent times.

Bluetooth Low Energy can translate into Vietnamese as Bluetooth low energy, also known by many other names such as Bluetooth Smart, Bluetooth LE, and BLE. This is a wireless networking technology known in 2006 invented by Nokia, which helps devices connect with each other and consumes very little power.

Bluetooth module PCB antenna is a wireless networking technology that uses low energy. Bluetooth Low Energy is a wireless networking technology that uses low energy.

First, Bluetooth Low Energy call Wibree, and then it integrates into Bluetooth 4.0, so it changed its name to Bluetooth Special Interest Group. By 2010, officially name Bluetooth Low Energy, bringing efficiency in optimizing energy consumption.

Is Bluetooth Low Energy the same as Bluetooth?

Many people wonder if Bluetooth Low Energy and upgraded version of Bluetooth. In fact, is Bluetooth Low Energy is a new technology that makes low-speed transmission more efficient with devices with little data?

Bluetooth module PCB antenna serves two completely different purposes. Therefore, they are not the same. As follows:

● BLE has the ability to exchange data with a very large capacity, including video and audio. Bluetooth can also transmit and process different types of data at a higher cost and with more energy.

● Low Energy Bluetooth costs a lot less than a Bluetooth module PCB antenna because it can run on batteries for many years in a row. This device applies when you want to recover data with little information without requiring large data transfer like Bluetooth.

What is the application of Bluetooth Low Energy?

Through LoT devices, what is Bluetooth Low Energy will help users get optimal efficiency during use. Until now, Bluetooth Low Energy has been widely applied in daily life such as:

Use in the smart home. For example, August Smart Lock will help users replace the electronic key with their phone. On the other hand, objects in the house can control easily and quickly by voice through smartphones.

What fields does Bluetooth module PCB antenna apply to?

Bluetooth module PCB antenna developed in response to a number of markets for low energy technology, especially in the smart home, health, sports, and fitness sectors. Possible applications include:

Identify assets with Bluetooth module PCB antenna that use BLE for near-range positioning. It can be seen in cars, motorbikes, and airport luggage.

● Healthcare bracelets, smart wearable devices such as Apple Watch, Samsung Fit

● IoT devices in smart homes such as door locks, automatic doors, and control lighting systems.

● Application and location tracking accessories

Items will attach to this device so that users can easily find them without wasting time searching with very high accuracy.

Application in proximity and location marketing technology such as Beacon will help users send promotional information and product details to customers. This is one of the great steps forward to identifying customers who are in your storage area quickly and accurately.

● Medical Facility

BLE is also used for health care purposes, including blood sugar monitoring when integrated into CGMP devices.

Application to produce smart bracelets, helping users to record information, track and synchronize data for smart home when practicing sports.

Note: To be able to integrate into the above applications, the Bluetooth module PCB antenna needs to go through the central system. This system can be a laptop, tablet, or smartphone, but must use the operating system Windows Phone, Android, ISO, Linux, macOS, Windows 8, 10.

Advantages and disadvantages of BLE

Bluetooth module PCB antenna brings many practical applications to human life. Bluetooth Low Energy, like many other devices, has certain advantages and disadvantages.

● Advantage

Bluetooth Low Energy has fast data transmission.

The ability to transfer data as well as establish a connection is very fast at only about 3ms.

BLE is not subject to interference like when using regular Bluetooth or wifi devices because it operates at the 2.4Ghz ISM band.

Bluetooth module PCB antenna has the remarkable advantage of very low energy consumption.

When using Bluetooth Low Energy, the device can work for many years. BLE brings many benefits when integrated into most of today's smart mobile phones. Bluetooth has a feature that turns off when there is no data coming and turns on automatically when there is data. Thanks to that, it helps to save a lot of energy during use. The cost to produce a Bluetooth module PCB antenna is not high, so the price to own this technology is relatively low.

● Disadvantages of Bluetooth Low Energy

The highlights of BLE technology compared to Bluetooth as mentioned above, it has its limitations. It can be summarized as follows:

In order to connect the Bluetooth module PCB antenna with regular Bluetooth, it is necessary to use the Bluetooth Smart Ready standard for peer-to-peer communication. As for the Bluetooth Smart standard, it can only communicate with Bluetooth Smart or Bluetooth Smart Ready.

Bluetooth low energy transmission time

The transmitted data information is very small, with the intermittent transmission time, which cannot apply to the fields that require continuous data transmission.

Data transmission distance

Data transmission distance limits to about 100m. Even, though there are cases that only transmit within a radius of 30m with a height of 2 - 5m will give high efficiency. Although the connection distance may be a bit longer than a normal Bluetooth module PCB antenna, about 100 meters depending on whether there is an obstacle or not, this distance can change. But still far behind with WiFi connection.

Transmission quality

There are many factors affecting transmission quality such as device orientation, obstacles, antenna design, operating environment, etc.

Bluetooth module PCB antenna has a modulation frequency of 1Mbps. The data throughput is very small, so it can't transfer for large content.

Thus, we have just learned in detail what Bluetooth Low Energy is as well as the advantages and disadvantages of Bluetooth Low Energy.
