BLUETOOTH TECHNOLOGY

Image
                                                        BLUETOOTH TECHNOLOGY Bluetooth is a short-range  wireless  technology standard that is used for exchanging data between fixed and mobile devices over short distances and building  personal area networks  (PANs). In the most widely used mode, transmission power is limited to 2.5  milliwatts , giving it a very short range of up to 10 metres (33 ft). It employs  UHF   radio waves  in the  ISM bands , from 2.402   GHz  to 2.48   GHz. [3]  It is mainly used as an alternative to wired connections to exchange files between nearby portable devices and connect  cell phones  and music players with  wireless headphones . Bluetooth is managed by the  Bluetooth Special Interest Group  (SIG), which has more than 35,000 member companies in the areas of telecommunication, computing, networking, and consumer electronics. The  IEEE  standardized Bluetooth as IEEE 802.15.1 but no longer maintains the standard. The Bluetooth SIG oversees the developm

  RJ 45 VS RJ 11   What is RJ45 and RJ11? As is known to all, “RJ” means registered jack and the number behind “RJ” means the listing number. So, do you know what is “RJ45” and “RJ11”? RJ11 RJ11 (Registered Jack 11) usually has a size of 6mm*9.5mm. It features 6 positions and 2 or 4 pins, which is widely used in the telephone system and ADSL/VDSL modem. A 6P4C RJ11 connectors are compatible to make 2 connections with 2 pairs. RJ45 RJ45 (Registered Jack 45)  is the most commonly used connector in network and telecommunication applications. RJ45 belongs to the category of 8P8C connector standard, which means that it has 8 positions and 8 pins/conductors. RJ45 connectors are compatible with many categories of Ethernet cables including Cat5, Cat5e, Cat6, Cat6a, and Cat8. RJ45 vs RJ11 : What’s the Difference? RJ45 connectors are very similar to RJ11 in their appearance, and you may confuse them. But in fact, they have different designs and functions. Construction RJ11 connectors are small,

I NTERNET OF THINGS   What is the Internet of Things (IoT)? Simply put, the Internet of Things is a system of interconnected physical devices that communicate via the Internet. These Internet of Things devices collect and share data with other devices, applications, and systems, and in many ways the data “talks” to us and the other things it’s connected to. From wearables to industrial sensors, IoT devices generate sensory, biotelemetry, and a myriad of other types of data. How does IoT work?  IoT is a system of Internet-connected devices. These devices are essentially mini-computer processors that use machine learning to act on data collected by sensors. IoT devices can range from smart warehouse vehicles to fitness trackers to cold storage temperature monitors.  A complete IoT system integrates 4 parts: 1. Sensors/devices Smart devices or sensors pass data to the cloud. 2. Data Collection and Connectivity Data is passed from a device or sensor to the cloud via some type of connection
