September 23, 2014— Connect One released G2 WiFi modules to support the latest 802.11b/g/n wireless standards for the Internet of Things (IoT) market. G2 modules provide:
- Full 802.11b/g/n support
- Easy switching between WiFi Access Point and WiFi Client Operation modes
- Industrial temperature range of -30°C to +85°C
The G2 modules offer 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. Designers gain immediate, full-featured connectivity without any WiFi driver development or porting, minimizing project development challenges and time to market. The G2 modules can also serve as independent WiFi access points where WiFi infrastructure does not exist.
Customers can use the modules to connect to and manage their deployed, in-field devices via standard WiFi devices, such as iPhones, iPads, Android phones, and other mobile phones and devices. To ensure complete security, the G2 line offers highly advanced Internet-level security. The module includes WiFi encryption algorithms (WEP/WPA/WPA2), Internet SSL communication and encryption algorithms. In addition, it provides a secure separation between the embedded application and the network in order to protect the application from attacks originating from the Internet. 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. Features:
- 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.
- 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.
- 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.
Any microcontroller with a built-in Ethernet MAC can be connected to WiFi with zero development effort,
Internet controller mode can be used with any hardware interface, and
The G2 modules include RMII, USB, SPI and fast UART interfaces for easy integration into existing or new designs. They are available with an antenna connector or a built-in antenna depending on the specific module chosen. The G2 line supports 10 simultaneous TCP/UDP sockets; two listening TCP sockets; SMTP, MIME, POP3, FTP, Telnet, and HTTP/HTTPS clients; and an HTTP/HTTPS embedded Web server with a Web site for the host application and one for configuring the module. They support 64-/128-bit WEP, WPA/WPA2, AES-128/256, SHA-128/192/256, and 3DES encryption; and the SSL3/TLS1 protocol for a secure client socket session and a secure FTP session.
