Interception of data and voice communications is a lawful obligation of telecommunications service providers. The demand for lawful interception solutions is generated by a number of stakeholders such as government regulators, law enforcement agencies (LEAs), and communication service providers to prevent crime, including fraud and terrorism. LEAs perform electronic surveillance as authorized by judicial or administrative orders while minimizing the violation of civil liberties and privacy to collateral users. Most of the countries have adopted lawful interception regulations. These regulations may vary from country to country. Lawful interception is the official legal access to private communications such as e-mail messages and telephone calls. Lawful interception allows companies to make their communications available to law enforcement officials when requested.

Atrial fibrillation is one of the most common types of arrhythmia and is characterized by fast and irregular heart rhythms. The atria of patients suffering from the disease do not function properly. Atrial fibrillation can cause chest pain, heart failure, or stroke. The doctor needs to identify the first detected event of atrial fibrillation in a patient. The occurrence of two or more events of atrial fibrillation results in it being considered recurrent. In paroxysmal atrial fibrillation, the arrhythmia ends spontaneously, whereas in persistent atrial fibrillation the arrhythmia continues for more than a week. The first detected event of atrial fibrillation can either be paroxysmal or persistent. The patient can also experience many episodes of paroxysmal atrial fibrillation and random episodes of persistent atrial fibrillation. Permanent atrial fibrillation involves continuous episodes of atrial fibrillation and occurs when the patient and the doctor agree not to re-establish regular sinus rhythm by any means, either by catheter or surgical ablation.

Lifestyle disease is associated with the way an individual or group of people live. Some of the lifestyle diseases include depression, sexual dysfunction, anti-aging, baldness, and obesity.

The global lock market covers the safety and security aspects of residential, commercial, and industrial spaces. Locks are offered in mechanical and electronical forms. The global lock market has been witnessing growth across regions due to increasing awareness about high-tech security systems among various end-users. Also, the deployment of smart solutions in developed and developing economies is driving the growth of the global lock market. Increasing security concerns across regions is driving the need for the installation of high-security locking systems in residential and commercial spaces. With the changing technology, vendors offer locks with highly sophisticated security systems. Electronic locking systems are high-tech offerings. Electronic locks are loaded with high-tech features that are integrated electronically to create smart systems.

LPWAN technologies operate at a low cost, with immense power efficiency. A few examples of these technologies are Sigfox, machine-to-machine (M2M) Spectrum, and NWave. LPWAN is suitable for applications that require connecting widely scattered devices. A connected smoke detector can trigger a smoke alarm with absolute certainty using this technology.

Transformers need an insulating medium to keep the temperature of the core windings in check as well as act as an arc-quenching medium. Oil is the most widely used type of insulating medium. Transformer oil is used as an insulation and arc-quenching medium in power and distribution transformers. Windings use cellulose insulation that has a strong affinity for oxygen and is immersed in transformer oil to prevent oxidation. Transformer oil is produced by the fractional distillation and subsequent processing of crude oil. It also finds application in circuit breakers and switchgears, which are traditional and use oil as the arc-quenching fluid. The global demand for renovation and expansion of the T&D network is on the rise, mostly triggered by the growing demand for electric power from almost every type of end-user, namely residential, commercial, and industrial sectors.

The display is one of the significant components for kiosks, portable display devices, TVs, monitors, laptops, and smartphones. For these devices, displays act as a platform for user interface and enhance the user experience. Rapid advances in technology in the display industry have taken place simultaneously with advances in the overall electronics industry.

Vitrified tiles are a type of ceramic tiles with low porosity. They are frequently used as an alternative to marble and granite flooring. This type of tiles is well known for its water and frost resistance. Vitrified tiles are made by hydraulic pressing a

mixture of ball clay, quartz, feldspar, and silica, which makes the vitreous surface.In this report, Technavio covers the present scenario and growth prospects of the global vitrified tiles market during 2017-2021. The report presents the vendor landscape and a corresponding detailed analysis of the key five vendors in the market as well as a list of the other prominent vendors. In addition, the report discusses the major drivers influencing market growth and the challenges faced by vendors and the overall market. It also examines key emerging trends and their influence on the current and future market scenarios.

VLC is a wireless technology that uses light emanated from LED bulbs in order to provide a network for high-speed communication parallel to Wi-Fi. This has led to it also being known as Li-Fi. Visible light spectrum is 10,000 times larger than radio frequency spectrum, and it is considered as an answer to the bandwidth limitations of radio frequency.The growth of the global VLC market is driven by several factors. One of the major drivers is the availability of high bandwidth, which ensures high data rate and data transfer. The congestion of RF spectrum is creating a demand for alternative sources of wireless technology such as Wi-Fi, Bluetooth, and ZigBee. The other drivers in the market are the efficiency and security offered by VLC systems, the visible light spectrum offering unlicensed use and high speed, and the fact that it is safe and applicable in almost all environments.

VR is a computer generated 3D environment, which engages the user in the virtual world by interacting with it. The user will be completely engaged in the environment and will be able to play around with virtual objects and also execute a series of actions.

Augmented reality (AR) AR technology helps in blending the digital content with the physical world. Computer generated images are displayed by it in the user's field of vision, and relevant information about the objects is provided in the real world. The user can scan the physical real world environment and get an enhanced or augmented experience by adding virtual computer-generated information.
