I S E I C T S O L U T I O N S E D U C AT I O N 5 4 OFFLOAD Each generation of wireless technology has revolutionized how people communicate and consume content Second generation cellular networks for example allowed people to text one another Third generation networks enabled far greater mobile broadband data Fourth generation networks enabled mobile video usage without frustrating delays Fifth generation cellular networks are expected to enable another revolution transforming how people and machines communicate and even how industries do business 5G network deployments are also expected to provide significant economic and efficiency gains in the markets where they are deployed Smart factory and smart city applications autonomous vehicles and machines and telemedicine applications are just a few of the examples where 5G technology is expected to impact a range of industries As such 5G cellular networks will bring with it a paradox once it is deployed Even as 5G networks will bring more spectrum to market the massive amounts of new connections that will be available could overwhelm networks once billions of diverse devices connect to the 5G networks So even as new spectrum comes to market operators will continue to need to use offloading techniques to keep the macrocellular network operating efficiently Already Wi Fi networks are used to help alleviate some of this data congestion in hopes of providing a seamless customer experience both outdoors and indoors That practice will continue as wireless demand increases driven not only by people but also machines that use wireless technology to communicate with each other The ability to leverage a variety of licensed and unlicensed spectrum across multiple frequencies using various technologies along with techniques to increase overall transmission bandwidth remains an essential part of the answer to meeting the demand for mobile connectivity The 5G Offloading Paradox By Greg Najjar Mark Reynolds Don Bach and Luke Lucas kristen beckman@ wia org @ WIAorg
