Connect One launches next-gen IoT WiFi modules

Connect One has launched its next-generation (G2) WiFi modules to support the latest 802.11b/g/n wireless standards for the Internet of Things (IoT) market. G2 incorporates these latest standards at up to 40 percent savings, while creating a no-change upgrade path for customers.

Improved WiReach Functionality
In addition to preserving form, fit, and function of existing modules, Connect One has enhanced and enriched the functionality available across the entire G2 line:

  • Full 802.11b/g/n support (previously available only on Connect One MAX modules)
  • Easy switching between WiFi Access Point and WiFi Client Operation modes
  • Industrial temperature range of -30°C to +85°C

The G2 modules offer excellent system performance for IoT connectivity with Broadcom BCM43362 WiFi Transceiver SOC and its 802.11b/g/n MAC and baseband functionality. The G2 modules build on this foundation and Connect One’s iChip Internet Controller , providing multiple hardware interfaces, extensive firmware, and a full suite of secure Internet protocols for WiFi client mode and up to eight WiFi users in router or access-point modes. The G2 modules can also serve as independent WiFi access points where WiFi infrastructure does not exist. 

To maximize customer investment, Connect One’s G2 WiFi modules offer a smooth upgrade path for the Nano WiReach and Nano Socket iWiFi   modules. These G2 module upgrades require no hardware or software changes for applications using existing Connect One WiFi modules. As well, the application interface—Connect One’s AT+i Application Programming Interface (API) —continues to be the same.

To maximize design-in flexibility, the G2 line builds on existing capabilities, offering firmware support for several modes of operation:

  • Embedded Router —LAN or WiFi clients gain a single cellular WAN connection to the Internet (3G router) or routing between LAN and WiFi networks,
  • Embedded Access Point —Devices containing WiFi can connect to the product’s embedded access point to control or manage processes,
  • LAN to WiFi Bridge —Transparent bridging of LAN over WiFi enables direct RMII connection to existing MAC hardware. Any microcontroller with a built-in Ethernet MAC can be connected to WiFi with zero development effort,
  • Serial to LAN/WiFi Bridge —Transparent bridging of serial data over LAN or WiFi is boosted by the module’s speedy 3-Mbps UART,
  • Full Internet Controller mode —Simple microcontrollers can use the modules’ rich protocol and application capabilities to perform complex Internet operations, such as e-mail, FTP, SSL, embedded Web server and others. Internet controller mode can be used with any hardware interface, and
  • PPP emulation —Existing (e.g., cellular modem) designs currently using PPP to interface to the cellular modem can connect transparently over WiFi with no changes to application or drivers.
