Introduction
– The convergence of readily available internet access, hardware, and enabling services is enabling a new wave of device connectivity
– The “Internet of Things” will continue to grow through the implementation of Machine to Machine (M2M) system integrations
– Devices that “need” to be connected, will be connected
– This presentation presents key enabling technologies available from the Arrow M2M ecosystem to implement connectivity solutions for a wide variety of applications

Wi-Fi Connectivity Technology Overview
![Page 39: Steve Weeres M2M Business Development Manager sweeres@arrow](https://reader033.fdocuments.us/reader033/viewer/2022050819/56813098550346895d967665/html5/thumbnails/39.jpg)
Wi-Fi Technology Overview
– Wi-Fi, is a local area wireless technology that allows an electronic device to exchange data or connect to the internet using the 2.4 GHz and 5.8 GHz ISM Bands
– Operation and functionality defined by IEEE 802.11
– Stations, components that can connect on a wireless network are either clients or access points
– Two basic modes of operation:
– Infrastructure mode; clients connect to a central access point which may serve as a bridge to other networks
– Peer to Peer mode; clients connect to each other in either ad hoc or Wi-Fi Direct networks
![Page 40: Steve Weeres M2M Business Development Manager sweeres@arrow](https://reader033.fdocuments.us/reader033/viewer/2022050819/56813098550346895d967665/html5/thumbnails/40.jpg)
Wi-Fi Technology Overview
– Wi-Fi enabled devices will typically be clients to an available access point
– The Wi-Fi interface in the device can also serve as an access point, allowing clients to connect
– The access point functionality can be “de-featured” to provide more limited connectivity functionality, defined loosely as a “Soft Access Point/SoftAP”
– SoftAP functionality is not standardized and is highly dependent on the networking stack implementation
![Page 41: Steve Weeres M2M Business Development Manager sweeres@arrow](https://reader033.fdocuments.us/reader033/viewer/2022050819/56813098550346895d967665/html5/thumbnails/41.jpg)
Wi-Fi Embedded Module Characteristics– Module Implementation Options Summary
– Hosted Wi-Fi modules are “software defined” radios, module selection dependent on features needed from application use cases
– Band support; b/g (legacy), b/g/n (common), b/g/dual n (select few), a/b/g/n (select few)
– Networking Stack resident or offboard
– Stack resident modules (fully hosted) provide AT command interface via serial port
– Stack Offboard; Stack code base must be procured and ported to the embedded platform. Interface is through SDIO or USB to low level radio interface on the module.
![Page 42: Steve Weeres M2M Business Development Manager sweeres@arrow](https://reader033.fdocuments.us/reader033/viewer/2022050819/56813098550346895d967665/html5/thumbnails/42.jpg)
Wi-Fi Embedded Module Characteristics– Module Implementation Options
– Wi-Fi only or Wi-Fi plus Bluetooth
– Connection modes supported; Infrastructure (client), Access Point, Wi-Fi Direct, Soft AP
– All modules support infrastructure mode
– Most modules can only be in one mode at a time
– No “standard” definition for Soft AP functionality, module dependent
– Configuration Methodology (setting SSID/Passphrase)
– Two options:
– Over the wired interface
– Via a wireless connection to the module Soft AP
![Page 43: Steve Weeres M2M Business Development Manager sweeres@arrow](https://reader033.fdocuments.us/reader033/viewer/2022050819/56813098550346895d967665/html5/thumbnails/43.jpg)
Wi-Fi Embedded Module Characteristics
Configuration via Soft AP
– Module is put in Soft AP mode (interface command or hardware initiated)
– Client device associates with the Soft AP
– Client device opens a browser and accesses the configuration web page resident on the module
![Page 44: Steve Weeres M2M Business Development Manager sweeres@arrow](https://reader033.fdocuments.us/reader033/viewer/2022050819/56813098550346895d967665/html5/thumbnails/44.jpg)
Wi-Fi Embedded Module Characteristics– Module Implementation Options
– Security Implementation Methodology
– Module to AP: WPA2 x
– End to End Security: SSL, SSH, EAP, etc
– Processor Interface
– UART, SPI (common)
– USB (available)
– SDIO (available, generally for modules with MCU hosted stack)
– HTTP Server function: customizable web pages hosted on module, accessed through SoftAP mode
![Page 45: Steve Weeres M2M Business Development Manager sweeres@arrow](https://reader033.fdocuments.us/reader033/viewer/2022050819/56813098550346895d967665/html5/thumbnails/45.jpg)
Wi-Fi Embedded Module Characteristics– Module Implementation Options
– Antenna Placement
– Antenna On-Board (internal) or Antenna Off-Board (external)
– Application space on module available
– Module Certification
– Most modules are fully certified
![Page 46: Steve Weeres M2M Business Development Manager sweeres@arrow](https://reader033.fdocuments.us/reader033/viewer/2022050819/56813098550346895d967665/html5/thumbnails/46.jpg)
Wi-Fi Embedded Module Characteristics
– Module Trends
– Module manufacturers continuing to focus development on “fully hosted” modules
– Module costs continuing to trend downward
– Modules allow custom web page visibility via softAP
– Simultaneous Client-SoftAP capability
– Wi-Fi with advanced SoftAP functionality considered as an alternative to BT/BTLE for Smart Device connectivity
– Industrial temp range devices becoming the norm

Wi-Fi Embedded Module Characteristics– New Wi-Fi module offerings enable connectivity from enabled
end node devices direct to router/AP
– New modules feature reduced peak power consumption enabling extended battery powered operation. Example:
– Tx current = 19 mA at 1 Mbps, 15 dBm, compared to 200 mA at 22 Mbps
– Devices also have Sleep and Standby modes to reduce power consumption
– Compact form factor allows small design footprint for reduced physical size devices
– On-board application code space and I/O can eliminate the need for a separate microcontroller
– Stack resident modules make microcontroller interface easy
