## 1 Introduction  
The development and deployment of innovative applications drive the continuous evolution of information and communication technologies (ICT). These advancements are motivated by the emergence of technologies, such as the Internet of Things (IoT) [1, 2], artificial intelligence, edge intelligence and cloud computing [3], blockchain, and miniaturized hardware components and systems [4], which collectively contribute to the creation of a smarter, more intelligent, and more proactive digital world [5]. These innovative applications have their own requirements, such as guaranteed and very high bandwidth, lower latency, energy efficiency, greater security, and other specific requirements [2]. To support the future media, continuous upgradation in network infrastructure, including the transition from 4G to 5G, and ongoing research on 6G technology, is essential. As new applications emerge, new challenges are posed along with plenty of opportunities, prompting further advancements in ICT to meet the evolving needs of society [6]. This innovation and development cycle ensures that this technology remains a key enabler of economic growth, social progress, wellness, and global connectivity.  
6G is a next-generation wireless communication technology that is under research and development. It has been named as International Mobile Telecommunications for 2030 (IMT-2030) by the International Telecommunication Union--Radiocommunication (ITU-R) [7]. The mobile communication standardization working group of ITU-R, Working Party 5D (WP 5D), is responsible for defining the vision and overall radio system aspects, including the requirements of next-generation mobile communication applications with 6G. Several standardization bodies, research groups, regulatory and government organizations, and operators are actively contributing to the 6G standardization process [8]. 6G promises ultra-fast data rates with near-zero latency, high energy efficiency, massive connectivity density, and reliability besides sensing, immersive communications, and communications empowered by artificial intelligence [7; 8; 9].  
We are looking forward to a new era of Tactile Internet, which will enable a new kind of interconnectedness and intelligent interaction through 6G. Tactile Internet is seen as the next evolution of the Internet to enable real-time interaction with haptic data over networks, allowing us to have a sense of touch and emotions through communication [10]. The realization of Tactile Internet will heavily rely on 6G and its integration with artificial intelligence [8].  
Although studies on 6G and the Tactile Internet exist, research on the Tactile Internet's application characteristics, their requirements, and their mapping is still in its early stages. Such a study will be critical in the 6G and Tactile Internet design considerations. This paper presents a study on 6G developments and Tactile Internet, their application characteristics and requirements, and the design challenges. The rest of the paper is organized as follows. Section 2 presents a discussion on 6G technology and its developmental progress. Section 3 presents a study on Tactile Internet, whereas Section 4 discusses its application characteristics, which need to be considered while designing the network. Section 5 focused on select Tactile Internet application requirements and technological capabilities of 5G and 6G. It deliberates on the importance of performance parameters for different Tactile Internet application characteristics and design considerations. Section 6 brief presents a study on various types of sensors that can be used in Tactile Internet. The paper is concluded in Section 7.
