Wireless Protocol Update
Most of us are familiar with Wi-Fi, BlueTooth, Zigbee and perhaps a few others, but there are newer wireless protocol network technologies that you may not have investigated. 
Protocol Networking Technology Update
Take a look at the table immediately above, compliments of DesignSpark. 
    BlueTooth was originally conceived to replace the rat's nest of cabling around your computer or for wireless headsets, and took on a life of its own by increasing its range, and adding other enhancements. Bluetooth low energy (aka Bluetooth Smart) came out with version 4.0, which includes Classic Bluetooth, Bluetooth high speed and Bluetooth low energy. As the name implies Bluetooth low energy is designed to run off of a coin cell. It provides single-mode with only the low energy stack and dual-mode with Bluetooth Smart functionality integrated into an existing Classic Bluetooth controller.
    Zigbee, which has been around for a while was motivated to be simpler and less expensive for personal area networks such as Wi-Fi and BlueTooth. Zigbee is a mesh network with low latency and low power.
    Z-Wave is oriented towards home automation and can be remote controlled via the Internet. There are hundreds of interoperable Z-Wave products marketed under different brands. It also uses a mesh network.
    6LoWPAN is an acronym of IPv6 over Low power Wireless Personal Area Networks. Since it is a protocol, range and rates are not applicable. Work was done to define encapsulation and header compression mechanisms to allow IPv6 to be sent over some of these wireless networks.
    Thread uses 6LoWPAN which uses 802.15.4 and is IP-addressable with cloud access and AES encryption.
    NFC is similar to RFID and applications include secure personal data storage such as credit card information. Its short range is deliberate. Both Google and Apple use some form of NFC for mobile payment.
    SIGFOX network and technology is aimed at the low cost machine to machine application areas where wide area coverage is required. Ultra-narrowband consists of free sections of the radio spectrum, particularly the ISM band. At these frequencies the wave length is longer than cellular and can pass through solid objects and reach distances of 620 miles at low data rates. Many machine to machine applications don't require the largest amount of data possible.
    Weightless by Neul is a new wide-area wireless networking technology, achieving coverage, battery life, module cost and simplicity.
    LoRa is an acronym for low-power wide-area network which is also designed for long range communications at a low bit rate.   
If you need wireless capabilities, CEPD can help you design the appropriate wireless protocol into your product.  -TG
