Wireless modules facilitate Web 2.0
WISM modules make it it easy for embedded engineers to add Web 2.0 capability to their designs
The widespread availability of Wi-Fi access points is leading to an increasing number of products using wireless connectivity to enable remote monitoring and control. This marks a shift from the use of Wi-Fi as a way to connect laptops for email and internet access to a much larger market of controlling machines.

It marks the start of what the internet gurus describe as Web 2.0, where web services can be provided from a host of sensing and monitoring devices.
Ezurio's WISM modules with the UWScript wireless oriented scripting language make it it easy for embedded engineers to add Web 2.0 capability to their designs.
'Implementing a Wi-Fi connection can be complex, as it requires considerable processing power, specific drivers, a TCP/IP stack and software to control the connection', said Nick Hunn, CTO of Ezurio.

'It's one of the reasons that so few devices connect to the internet today'.
'Our customers were frantic to get a solution - they asked us to design them a module that removed all of that complexity'.
Ezurio's wireless LAN Processor Module provides a UART interface for data and control, 12 GPIO lines and two 10 bit ADCs, as well as 802.11 drivers and TCP/IP stack.
'Most embedded servers are limited to setting up the device parameters', continued Nick Hunn.
'That's not enough for today's designer'.
'We've extended that with functionality which can access and embed local information to provide dynamic web content for a new generation of Web 2.0 applications'.
The module includes an interpreter running a powerful scripting language that removes the need for any host processing capability.
This allows complete applications such as internet thermometers to be implemented completely inside the WISM module, drastically reducing the cost of producing wirelessly enabled products.
Key application areas for wireless internet access are machine to machine (M2M) applications and cellular-free telematics.
Ezurio's Wi-Fi device server modules provide the ideal building block to get wireless concepts into production in the shortest possible time.
Ezurio offers two form factors - a compact 25 x 35mm module that is pin-compatible with its BISM Bluetooth module, and a larger module that is pin-compatible with Siemens' MC55 GPRS modules.
These combinations allow designers to lay out their PCBs to accommodate a variety of different wireless standards.
Ezurio's WLAN modules are also available with a UDP stack and SLIP interface, for use in equipment which already contains a TCP/IP stack.
