ABSTRACT5G technology is an improved technologywhich gives improved connectivity and is different from previous generations.5G offers machine type communication where the network connects billion ofusers. The Internet of Things (IoT) is an emerging and promising technologywhich tends to revolutionize the global world through connected physicalobjects.
IoT deals with low-power devices which interact with each otherthrough the Internet. LPWA networks are currently being deployed for IoTapplications. 5G promises to bring the reliability, latency,scalability, security and ubiquitous mobility that would be needed for severalmission-critical services in the IoT space and beyond. Moreover,5G brings new infrastructure and design with low costs, high agility and at lowenergy consumption making it a key component of the communications andconnectivity layer of the IoT technology stack. KEYWORDSIOT,5G, LTE, Low-Power Wide-Area (LPWA), cellular technologyA large variety of communication technologieshas gradually emerged, reflecting a large diversity of application domains andof communication requirements. LTE isintroduced for mobile devices but it is not well suited for IoT devices becauseof low-power and low data rate. The basic fundamental issues for IoT applications isthe low power operations, because mostIoT devices are battery powered sensor nodes which could be installed atinaccessible regions, and replacing or recharging the batteries of such devicesis not feasible.Security and privacy are also veryimportant requirements for the IoT because of the built-in heterogeneity ofInternet connected smart objects and the ability to ensure that information thatare transmitted and physical objects connected through the communication mediumare properly monitored and controlled.
The other requirements are lowdeployment cost, long battery life, low device cost, extended coverage area,scalability.EXISTING IOT COMMUNICATION TECHNOLOGYLow-Power Wide-Area (LPWA) technologiesare the existing technology for IoT applications that are currently being usedin connecting both sensors and controllers to the Internet without theintrusion of Wi-Fi or cellular networks. Their unique features are wide-areacoverage, high energy efficiency, channel bandwidth, data rate, and low powerconsumption. The main features of current technologiesfor IoT are categorized into long-range networks, short-range networks andcellular technology. Due to demand of connectivity cellular technology hasintroduced their own IoT device connectivity landscape.The new mobile generation has beenextensively used to enhance the quality of voice communications as well asenabling the opportunity for a new global connectivity solution for end-userswith the objective of ensuring that ubiquitous communication is achieved withnew service requirements.The second generation (2G) technology canbe used for services including short message applications and fax systems andit is not reliable for applications such as multimedia and web browsing.
2.5Gnetworks were introduced to improve the data capacity by adding packet datacapability using General Packet Radio Service (GPRS) and Wireless ApplicationProtocol (WAP).The third generation (3G) cellularevolutions lead to massive connectivity of things beyond multimediaapplications such as video conferencing in mobile phones. The tremendous growthof the Internet affects both wired and wireless communications, and there is aneed to support the rapid growth of the mobile communication industry.4G LTE networks provides high speed andbandwidth to the most advanced IoT applications. LTEwas created as an upgrade to the 3G standards. LTE brings amazing new capabilities to the cellular business likeexpanding carrier capacity, providing high data rates needed by growing newapplications and making cellular connectivity more reliable. 5G AS IOTCOMMUNICATION TECHNOLOGY 5G is expected to reachnetwork speeds up to 20 Gbps (gigabits persecond) or more.
It is aheterogeneous network that integrates 4G, Wi-Fi, millimetre wave, and otherwireless access technologies. 5G mobile networks have to cater for the massivedeployment of IoT with billions of connected smart objects and sensors thatwill be a global representation of the real world. The 5G new radio network isconsidered for IoT because the demand for machine communications continue togrow extensively for connecting a massive number of smart devices with thebenefits of using cellular networks.By offering lower cost, lower energy consumption and support for very largenumber of devices, 5G is ready to enable the vision of a truly global Internetof Things.
5G mobile networks are visualised as apromising next generation technology to support the massive deployment ofsimultaneously connected heterogeneous devices with new service requirementsbased on wearable things, improved better coverage edge, low latency, highversatility and scalability for efficiently enabling IoT applications.
