How about a complete system for your front door? The Aiphone version of the old fashioned doorbell has both chimes and voice capabilities! The CCS-1A Chime Com2 Door Entry compact unit takes up no more room than a light switch plate and delivers clear audio to the user.
The Aiphone Tenant Station is another excellent product. It offers great features such as a large Push-To-Talk button, door release button, 4” black and white monitor, security guard call button, volume control, and you can use up to 500 stations in one system. (more…)

AirFiber wants to break the perception that SLAs are not possible with free space optics. The AirFiber 5800, a protocol-agnostic product that has up to 1.25 Gbps of total capacity, is a fault-tolerant system to support comparable capacity and quality found in fiber-based products. Incorporating its proprietary “Redundant Link Controller” technology, AirFiber claims carriers can deploy FSO links that are immune to data loss even in the face of link interference. And if interference does occur on one of the links, the RLC can maintain error-free communications by utilizing data supplied via the redundant link. Designed to meet carrier-class requirements, the 5800’s active monitoring and control mechanism automatically adjusts for external environmental disruptions such as rain and building sway.

While incremental changes to router technology have made them faster, denser (number of interfaces) and generally more efficient, the router’s basic monolithic architecture, in which a single processor performs all routing calculations, hasn’t changed. This has become more of a hindrance than a help to carriers, ISPs and enterprises looking to extend the reach of their networks while having to cut capital and operations costs.
Because monolithic routers only support a single routed network, large numbers of routers must be deployed in any location servicing multiple customers, networks or network services. Virtual routers attempt to solve this scalability problem using software to share a single route processor among multiple customers, but this approach is wrought with potential hazards and still contains the monolithic route-processing architecture that is the underlying problem.

In mobile wireless, there’s one inescapable truth: spectrum is finite. Couple that with a shift in Wall Street’s expectations and ongoing growth in minutes of use in voice and data, and the drive to maximize existing infrastructure is essential.

Pressure continues to mount as operators begin offering data services, a market the Strategis Group projects will have a penetration rate of nearly 60 percent by 2007. AT&T’s launch of GSM/GPRS data services and partnership with Cingular to build an overlay GSM network atop its TDMA network will likely be a big mover. CDMA carriers like Verizon and Bell Canada have launched their 1XRTT data networks, and Sprint PCS is not far behind.

Even moves like the FCC’s spectrum cap lift from 45 MHz to 55 MHz are a quick fix; data services will eat up spectrum quickly. While building more base stations is the easy answer, the realities of cost and zoning issues are forcing carriers to examine new alternatives.
