Aaronia EMI EMC Probe Set Sniffer

Aaronia EMI EMC Probe Set Sniffer PBS1 & PBS2 (100kHz to 1GHz(3GHz)

Our EMC probe set for the SPECTRAN NF-50xx and HF-60xx Analyzer-Series allows for straightforward pinpointing and measurement of interference sources from 100kHz to 1GHz (3GH) in electronic component groups as well as execution and monitoring of generic EMC measurement. Our sniffer set includes a total of 5 probes: 3 probes for magnetic field measurement and two for measurement of electric fields.
All probes are covered with an insulating layer, thus allowing safe measurement of oscillators or mains lines.
The PBS2 probe-set additionally contains a high-performance pre-amplifier, allowing measurement of significantly weaker interference sources, boosting the sensitivity of our instruments by up to 40dB.
Perfect for locating interference sources which might have been found e.g. in an EN55011, EN55022 or EN50371 (Class A or Class B) survey. After implementing appropriate changes in the circuit, their efficiency can easily and reliably be verified. That way, expensive and time-consuming re-assessments in an EMC laboratory can be skipped.

WiMAX Connectivity and Solutions

WiMAX covers a couple of different frequency ranges. Basically, the IEEE 802.16 standard addresses frequencies from 10GHz to 66GHz. The 802.16a specification, which is an extension of IEEE802.16, covers bands in the 2GHz-to-11GHz range. WiMAX has a range of up to 30 miles with a typical cell radius of 4–6 miles.

WiMAX's channel sizes range from 1.5 to 20MHz as well, and offer a WiMAX-based network the flexibility to support a variety of data transmitting rates such as T1 (1.5Mbps) and higher data transmitting rates of up to 70Mbps on a single channel that can support thousands of users. This flexibility allows WiMAX to adapt to the available spectrum and channel widths in different countries or licensed to different service providers.

WiMAX supports ATM, IPv4, IPv6, Ethernet, and VLAN services. So, it can provide a rich choice of service possibilities to voice and data network service providers. In addition, WiMAX provides an ideal wireless backhaul technology to connect 802.11 wireless LANs and commercial hotspots with the Internet.

The WiMAX-based solution is set up and deployed like cellular systems using base stations that service a radius of several miles/kilometers. The most typical WiMAX-based architecture includes a base station mounted on a building and is responsible for communicating on a point to multi-point basis with subscriber stations located in business offices and homes. The customer premise equipment (CPE) will connect the base station to a customer as well; the signal of voice and data is then routed through standard Ethernet cable either directly to a single computer, or to an 802.11 hot spot or a wired Ethernet LAN.

WiMAX-based solutions include many other advantages, such as robust security features, good QoS (Quality of Service), and mesh and smart antenna technology that will allow better utilization of the spectrum resources. Also, the WiMAX-based voice service can work on either traditional Time Division Multiplexed (TDM) voice or IP-based Voice, also known as Voice over IP (VoIP).

Broadband Wireless Access

WiMAX (Worldwide Interoperability for Microwave Access) is the IEEE 802.16 standards-based wireless technology that provides MAN (Metropolitan Area Network) broadband connectivity. WiMAX is an Air Interface for Fixed Broadband Wireless Access Systems, also known as the IEEE WirelessMAN air interface. WiMAX-based systems can be used to transmit signals as far as 30 miles. So far, WiMAX can offer a solution to what is normally called the "last-mile" problem by connecting individual homes' and business offices' communications.

WiMAX

WiMAX, meaning Worldwide Interoperability for Microwave Access, is a telecommunications technology that provides wireless transmission of data using a variety of transmission modes, from point-to-multipoint links to portable and fully mobile[citation needed] internet access. The technology provides up to 3 Mbit/s broadband speed without the need for cables. The technology is based on the IEEE 802.16 standard (also called Broadband Wireless Access). The name "WiMAX" was created by the WiMAX Forum, which was formed in June 2001 to promote conformity and interoperability of the standard. The forum describes WiMAX as "a standards-based technology enabling the delivery of last mile wireless broadband access as an alternative to cable and DSL

Wireless broadband

Few WISPs provide download speeds of over 100 Mbit/s; most broadband wireless access services are estimated to have a range of 50 km (30 miles) from a tower. [1] Technologies used include LMDS and MMDS, as well as heavy use of the ISM bands and one particular access technology is being standardized by IEEE 802.16, also known as WiMAX. WiMAX is highly popular in Europe but has not met full acceptance in the United States because cost of deployment does not meet return on investment figures. In 2005 the Federal Communications Commission adopted a Report and Order that revised the FCC’s rules to open the 3650 MHz band for terrestrial wireless broadband operations. [2] On November 14, 2007 the Commission released Public Notice DA 07-4605 in which the Wireless Telecommunications Bureau announced the start date for licensing and registration process for the 3650-3700 MHz band. [3]

Initially, Wireless Internet Service Providers (WISPs) were only found in rural areas not covered by cable or DSL. [4] These early WISPs would employ a high-capacity T-carrier, such as a T1 or DS3 connection, and then broadcast the signal from a high elevation, such as at the top of a water tower. To receive this type of Internet connection, consumers mount a small dish to the roof of their home or office and point it to the transmitter. Line of sight is usually necessary for WISPs operating in the 2.4 and 5GHz bands with 900MHz offering better NLOS performance.
