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
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
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.
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
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
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
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
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 • Limited 802.11a module offerings, 802.11ac modules 1-2 years out
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
