Wired (Fibre/CatV etc.) Sender Wireless Receiver Wireless Characteristics Distance vs. Power vs. Frequency f Distance Wireless Communication Data Rate Power Range Reliability Latency Frequency Bandwidth Communications Options Source: http://postscapes.com/internet-of-things-technologies Wireless local area network (WLAN) products that are based on the Institute of Electrical and Electronics Engineers' IEEE 802.11b/a/g/n standards Uses short-wavelength radio transmissions in the ISM band (from 2400–2480 MHz), creating personal area networks (PANs) with high levels of security. BLE/Bluetooth Smart: Uses the same technology with simpler modulation scheme- Not backward compatible to Bluetooth but very power efficient. Frequency: 2.4 GHz, and 5.0 GHz bands. Range: Common range is up to 100m but can be extended. Applications: Routers, Tablets, etc Power: Normal Frequency: 2.4 GHz Range: 1-10m Applications: Hands-free headsets, key dongles, fitness trackers Power: Normal (exception – BLE) Technology that enables smartphones and other devices to establish radio communication with each other by touching the devices together or bringing them into proximity to a distance of typically 10 cm (3.9 in) or less. Frequency: 13.56 MHz Range: < 10 cm Bit rate: 424 kbit/s Applications: - Android Beam Mobile Wallet, Smart car keys Power: Very low ZigBee is a specification for a suite of high-level communication protocols used to create personal area networks built from small, low-power digital radios Frequency: 2.4 GHz and 868/915 MHz bands. Range: 10-20m Applications: - Home automation Wireless Sensor networks, Smoke and Intruder warning Bit rate: 20-250 kbit/s Power: Low Radio transceivers and proprietary protocols (radio systems) that uses lower ISM frequency bands. IEEE 802.15.4 standard. To connect to the IoT, Sub-1 GHz systems need an application-layer Internet gateway. In many cases this is simply a personal computer running a TCP/IP stack. Frequency: 433/868/915 MHz. Range: 25 km Applications: - Security systems - Industrial control Power: Moderate Summary of Wireless Technology Parameters Source: Wireless Connectivity for The Internet of ThingsGil Reiter, Texas Instruments, White Paper Mobile Technologies 1G Analog Voice 2G 3G 4G-LTE Digital Voice + low speed data + SMS + MMS Voice +Data (Video + Internet Browsing) - VoIP Voice + High speed data VoLTE Frequency: Frequency: Frequency: Data Rate: ~20 kbps Data Rate: 3-42 Mbps Data Rate: ~150 Mbps - 900/1800/1900 MHz. - In SL: 900/1800 MHz - 900 - 2100MHz. - In SL: 2100 MHz - 700/900/1800/2300/2600MHz. - In SL : 1800/2300 MHz • 4G-LTE • LTE-Advanced Fourth generation of mobile telecommunications technology, succeeding 3G. High speed broadband access LTE Advanced is a mobile communication standard and a major enhancement of the Long Term Evolution (LTE) standard based on carrier aggregation. Frequency: 700 - 2600MHz.
