Newly established industry alliance dedicated to adding IP protocol to wireless sensor networks
Companies supporting the use of Internet Protocol (IP) in sensor networks have organized an IPSO Alliance (IP for Smart Objects Alliance). The first goal for IPSO to begin work is to achieve IPv6 interoperability on the IEEE 802.15.4 standard. Proponents claim that IP can directly connect sensors and other simple networks to the Internet, eliminating the need to resolve gateways. However, leading developers claim that smart technology is needed to embed IPv6 into the storage and power management of sensor networks.
About 24 companies have become IPSO's initial member companies, including Atmel, Cisco, Emerson, Freescale, and Sun Microsystems. They have formed a competitive relationship with members of the Zigbee Alliance and other supporters of similar agreements.
"Technically inclined people like IP because it means that there is no need to build a gateway to resolve, and people who are market inclined will ask what the ecosystem of the manufacturers will be after this," said the chairman of the alliance, which has rich sensor network development. Experience Geoff Mulligan said.
"Some people don't know that the IP function can be added to a device under two dollars," he added. "It can be added in a very small memory, only 4Kbytes RAM and 32 Kbytes flash."
"The information given by the IPSO Alliance shows that the development of sensing and control (network), and power (access via) is accelerating," said Mareca Hatler, principal analyst at On World. It has attracted everyone's attention and is called 6LoWPAN technology. "She added that network engineers first worked on the IP network on 802.14.5.
"ZigBee, because the standards were set earlier, has taken more attention for granted in the past few years," said George West, head of market observation at West Technology Research SoluTIons LLC. , Which can change ZigBee ’s preconceived thinking and market share. "
However, to be commercialized, a standard is needed, West added: "Most organizations are developed based on TCP / IP, and this architecture can be well extended on 6LowPAN."
The alliance hopes that there will be an interoperability plan by November, which will initially target the interoperability testing of dozens of 6LoWPAN software protocol stacks that have been released so far.
"After that, some of us will pay attention to the power consumption budget and the interoperability of wireless links, but we are still considering the plan." Mulligan, chairman of the 6LoWPAN group, said.
The alliance hopes to attract more terminal manufacturer groups to join. Many manufacturers are already developing products for IP sensor networks, but the application field is relatively narrow. There are some aircraft projects (including a project of the US military), others include An electronic instrument project in Florida.
"We are still in our infancy, but IP is very mature," Mulligan said. "I think we are ready for chips, nodes, software stacks, gateways, and even carrier-class routers."
In addition to interoperability, the alliance also focuses on service markets and educational functions. However, before this, special work is required to develop standards, and the impact of standards is significant.
6LoWPAN has been extended to security, node generation and other features. Related efforts to define routing protocols for 6LoWPAN no longer require market demand analysis.
Microwave PCB
microwave PCB`s is a type of PCB designed to operate on signals in the megahertz to gigahertz frequency ranges (medium frequency to extremely high frequency). These frequency ranges are used for communication signals in everything from cellphones to military radars. The materials used to construct these PCB`s are advanced composites with very specific characteristics for dielectric constant (Er), loss tangent, and CTE (co-efficient of thermal expansion).
High frequency circuit materials with a low stable Er and loss tangent allow for high speed signals to travel through the PCB with less impedance than standard FR-4 PCB materials. These materials can be mixed in the same Stack-Up for optimal performance and economics.
The advantages of using materials with a low X, Y and Z CTE is a resulting PCB structure that will remain extremely stable in high temperature environments while operating at up to 40 GHz in analog applications. This allows for the effective placement of very fine pitch components including, in some cases, bare die-attach. Additionally, the low CTE materials will facilitate the alignment of multiple layers and the features they represent in a complex PCB Layout.
