Cutting the Cord: How Bluetooths Revolutionized Wireless Communication

Bluetooth technology is a wireless communication protocol that allows devices to connect and exchange data over short distances. The technology was first developed in the 1990s by a team of engineers at Ericsson, a Swedish telecommunications company, and has since become a ubiquitous feature in a variety of devices, including smartphones, laptops, and wireless headphones. At its core, Bluetooth technology uses radio waves to transmit data between devices. Each device has a small transceiver that sends and receives signals, allowing them to establish a secure connection. When two devices are paired, they exchange a series of codes to verify their identities and establish a secure connection. Once a connection has been established, Bluetooth devices can communicate with each other using a variety of protocols, including the Advanced Audio Distribution Profile (A2DP) for streaming audio and the Hands-Free Profile (HFP) for making phone calls. One of the key advantages of Bluetooth technology is its low power consumption, which allows devices to maintain a connection while conserving battery life. Additionally, the technology has evolved over the years to support faster data transfer speeds, longer ranges, and more advanced features. As the world becomes increasingly reliant on wireless technology, Bluetooth will undoubtedly continue to play a critical role in connecting devices and enabling seamless communication between them.

Five Smart Ways to Secure Your Smart Phones

We live in an age when people are increasingly becoming dependent on their smartphones for just almost everything. Losing one’s phone is akin to losing one’s identity as we become very involved and dependent on our phones. However, while conducting transactions through the phone, we must always be alert to not fall prey to cybersecurity breaches. Learn how you can make your phones more secure to prevent personal information and passwords from being stolen. Lock your home screen Locking your phone is an obvious way of keeping off prying eyes when your phone is left unattended. It helps to secure your private information as no one will have access to your phone. It is also suggested to go to settings and increase your password length to the maximum so that your phone will be hard to hack. Do not charge the phone in public ports This advice is a bit disappointing as it is very convenient for us to charge phones at public ports like the one found in airports, planes, conferences, shopping centers etc. However, along with convenience, we may encounter risks too as it has been proved that phones are susceptible to security breaches at public ports. If an outlet is compromised, it can lead to transmission of your data allowing hackers to access your emails, photos, texts and contacts. Switch off Bluetooth Often, by default Bluetooth is ‘on’ in iPhones and Android phones. While it saves a tap of a finger, it may also be a channel of invasion for hackers to invade your privacy. Therefore, always turn your Bluetooth off to avoid your smartphone from being hacked. Update software regularly You may often postpone or avoid update notifications on your phone, but by doing so you are making your phone prone to hackers. According to experts, the longer you go without updating your phone and software, the longer your data is at risk for any malware malfunction. Use a VPN If you have to secure connection through a private network over the internet use a Virtual Private Network or VPNs. They allow users to send or receive data over public or shared networks without allowing unauthorized users to see it. Follow the above measures to keep your smartphone safe from hackers.
