Internet of Everything (Kopie 1)

The new Low Power WiFi Solutions from Qualcomm Atheros

Yesterday everybody was still talking about the “Internet of Thing” (IoT); today, everybody’s talking about the "Internet of Everything" and “AllJoyn”. These terms are understood to mean the total networking of all electronic devices from all conceivable sectors, such as household appliances, entertainment electronics, home and building automation, and mobile terminals. The intention is that the devices should be able to “talk” to one another directly, even without an access point, with the user having access to them via an Internet application. As well as the processing of constantly increasingly amounts of data, and the growing complexity of SW and protocols, with Wi-Fi solutions the demand for Low is growing louder. Qualcomm Atheros has the answer – the two new modules QCA4002 and QCA4004.

The two new SoC modules QCA4002 and QCA4004 (manufacturing process: CMOS 55nm from TSMC) provide an intelligent platform for all IoE applications where costs and low-power optimization really count. Both SoC’s support 802.11 a/b/g/n (2.4 GHz and 5 GHz), in Single as well as in Dual Mode, with the integrated network controller (Xtensa CPU, 130 MHz) can process a wide range of TCP/IP (IPv4/IPv6)-based applications with the most widely differing security protocols (WPS, WPA, WPA2, etc.) at a data rate of up to 150 Mbps. As well as a sleep mode fitted with special features, the Green Tx Power Saving Mode and the Low Power Listen Mode are particularly impressive when it comes to reducing power loss. Both modules can be connected as a modem via an SPI/UART interface to a host processor, but they both have enough computing and memory resources to integrate an application completely, even without an additional host.

Features
• IEEE 802.11n Single Stream 1x1
• Dual-band 2.4 GHz/5 GHz
• Integrated PA, LNA with support for external PA, and LNA
• Single or dual Rx front end for receive diversity
• On-chip processor and memory
• Green Tx power savings
• Low power listen
• Lower power modes – IEEE Sleep with low power consumption and optimal state transition times – Power optimized listen, receive, transmit, and associated operating modes – Suspend mode (QCA4004) for hostless mode of operation with very low power consumption – Store and recall for hosted mode of operating to maintain state while minimizing power consumption
• Date rates up to 40 Mbps
• Full security support: WPS, WPA, WPA2, WEP
• SPI host interface Allows for simplified connection to local host microcontroller Host driver source code and programming API is available
• UART host interface – Allow simple interfacing to microcontrollers – With an AT style command set
• Integrated IPv4/IPv6 networking stack
• SSL security
• HTTP, DNS services
• On-chip user development for hostless applications – Real-time operating system (RTOS) on the chip central processing unit

Supported toolchain
• Manufacturing tools for manufacturing configuration and test
• AllJoyn™ software ensures seamless communication between devices, enhancing ease-of-use for consumers.
Currently supported development environment
• QCA4002 is currently supported with the DB142 development board
• Reference module platforms are available for QCA4002/4 – SP140 is the microcontroller base board – SP141 is the solder on to SP140 QCA4002 module – SP143 is the solder on to SP140 QCA4004 module
