The Co-Existence Of Multi-RATs: A Look At How Radio Access Technology Keeps Us Connected

The Co-Existence of Multi-RATS The Evolution of RADIO ACCESS TECHNOLOGIES & Why We Need Them These days you can surf the web, send a text, stream live TV, and connect to Bluetooth - all at the same time. Being "connected" has become a way of life, and it's made possible by the ever-evolving world of Radio Access Technologies. How Does the Tecl ology Work? A Radio Access Technology (RAT) is the underlying physical CN connection method for a radio Core Network based communication network. RAN Radio Access Network UE UE UE User Equipment such as phone, computer, vehicle, etc. Why Are Wireless Networks Important? 3-n=[) These technologies These technologies facilitate mobile have created a world communications and without wires data transmission Everyday Connections Depend On Radio Access Technologies WLAN/WIFİ Wireless Local Area Network Wi Fi Uses high frequency radio waves (instead of wires) to connect Range spans rolatively short Devices with IEEE Modern voice/data 802.11 standard are uses include wireless distances branded as WIFI connections within a two or more devices home, office, school, etc. Repeaters can expand wireless signals to the Internet to cover larger areas such as shopping malls, sports stadiums, etc. BLUETOOTH Technology ..... Short-range Uses radio Replaced R-232 Modern voice/data uses include music streaming. wireless technology. Relays/repeaters spectrum in the data cables ISM band from cellular headsets, can be used to 2.4 to 2.485 GHz short-range medical devices, personal security applications, traffic control devices, etc. extend range of connection LTE Long Term Evolution HD Wireless standard Low latency for rapid Modern uses include HD for GSM/UMTSs data transmission video streaming, voice (VOLTE is standard), USB networks & content streaming. enhanced voice quality mobile, broadband modems DECT Digital Enhanced Cordless Technology Multiple handsets Channels reserved for Modern voice-only uses to one base station voice communication include homes and and one main won't interfere with office buildings with phone line other wireless devices several cordless devices operating from the same phone line NFC Near-Field Communication (DO IIII Short-range wireless technology allowing Simple setup allows for Both devices must have an NFC chip two devices to contactless exchange data payment Slower than Modern uses include mobile pay Bluetooth, but stations, NFC-enabled mobile uses less power phones, electronic identity and doesn't documents, keycards, gaming systems such as Wii U, etc. require pairing Why Do Everyday Connections Depend On So Many Different RATS? And Why Is Their Coexistence So Important? Different technologies "Always Be Connected" - Modern philosophy Technologies are always evolving & most modern are better suited for that defines the desire specific use cases, and and expectation to be able to connect devices support no single technology is sufficient to handle the growing demand for access, speed, and availability multiple RATS anytime, anywhere, with anyone, for any reason Coexistence prevents data overload, improves New wireless Multi-RATS mitigate technologies data overload, user experience, & progressing network crashes, maximizes customor service within tight cost constraints rapidly, but older technologies are Jams, lags, etc. still in use Where Will The Future Take Us? 4G 4G Eventually the loT (Internet Amount of Demand will WIFI data usage of Things) will lead to a demand for more power exceed the is reaching capabilities of 4G and faster Internet speeds critical mass Coordination and Handovers for seamless cooperation between RATS (COMP) will become increasingly important user experience will become important (IFOM, Hotspot 2.0) New spectrums are being explored for higher bandwidths (ex. millimeter wave) Li Fi Potential uses: Development of alternative Light Fidelity uses LEDS (Light Emitting LEDS can transmit data up to 10,000 times faster than LED street lamps technologies, Diodes) to transmit fueling mobile such as LiFi data to a receiver electromagnetic radio waves communication and communicate within a city Will help solve the problem of too much data and not enough space. 50M 4G speed 25M 5G speed 2015 2020 Number of connected devices 5G will be 1,000 is expected to double from 25 billion in 2015 to 50 billion in 2020 times faster than 4G Each and every one of us benefits from cutting-edge innovations in Radio Access Technologies, and there is only more to come in the future.
