Anritsu Company Adds TETRA Analysis and Coverage Mapping to Industry-leading LMR Master

Some of these trained writers on the internet are at such a top level that i wonder if any of them have ever printed a paperback? so every now and then i like to highlight these superb articles and here is one i found remarkable the other day.

Anritsu Company introduces TETRA analyzer and TETRA coverage mapping options to its industry-leading LMR Master™ S412E handheld analyzer. Combining the LMR Master’s best-in-class performance and compact durable design with the new TETRA measuring and analysis tools makes the handheld analyzer the most comprehensive test solution for deploying, installing, and maintaining public safety, transportation, utility and critical communication networks, including those utilizing the TETRA technology.

Equipped with the new options, the LMR Master S412E can be used by field technicians and engineers for over-the-air and coverage analysis of two way radio networks. For advanced field analysis, the TETRA analyzer includes a special TETRA Summary display so users can view key data, such as base and mobile color codes, mobile network code, location area code, and mobile station maximum transmit power level. This new capability, coupled with the industry-leading receiver technology of the LMR Master S412E, allows users to quickly, easily and accurately diagnose and troubleshoot system performance of TETRA networks using over-the air analysis without preamplifiers.

In addition to new capabilities for TETRA networks, Anritsu has updated and enhanced the LMR Master Options 721 and 722 to match technical and lexical changes in the ITC-R Positive Train Control (PTC) standard. Among the updates are the alignment of symbol rates to “Half Rate” and “Full Rate,” and support for new “burst/packet” air interfaces in the ITC-R standard, including updated signal generator patterns.

Further extending the capabilities of the LMR Master S412E, Anritsu has added support for the MA2700A InterferenceHunter™ Handheld Direction Finding System. Equipped with a built-in electronic compass, GPS receiver, and Preamplifier, the MA2700A can be attached to a wide variety of directional antennas.

The TETRA options expand the already-comprehensive measurement capabilities of the LMR Master S412E, which combines all of the tools required to install, maintain, and certify analog and digital Land Mobile Radio (LMR) and Professional Mobile Radio (PMR) networks in the shop or field. All LMR Master S412E analyzers come with a 42 dB directivity/100 dB transmission dynamic range VNA-based cable and antenna analyzer, ultra-low noise spectrum analyzer, signal generator, internal power meter, and analog FM analysis and coverage mapping.

Users can extend the value of their LMR Master S412E investment by adding options, such as interference analyzer, external power sensors (inline and terminating), distance-to-fault (DTF), and vector voltmeter. Signal analyzer/generator options are available for APCO P25 (Phase 1 FDMA and Phase 2 TDMA), NXDN™, MotoTRBO™/DMR, and TETRA. The LMR Master S412E also offers analysis of LTE and WiMAX (IEEE 802.16 fixed and mobile) for mobile broadband networks. When equipped with the optional internal GPS, coverage analysis for all signal analyzers is available. All this testing capability is designed into a rugged, portable, handheld, battery-operated touchscreen package.

The LMR Master S412E with TETRA analyzer and TETRA coverage mapping options is available in 4 to 6 weeks.

Understanding Wireless LAN networking

This piece is posted by the faithful permission of 2 way radio skiing.co.uk, that is the original site. please get permission from that website before reposting this short article.

Understanding wireless and wireless LAN networking allow you to correctly plan should you require Radio Hire and design the effective deployment of wireless systems whether it is home-networking or using outside lengthy-range WLAN for rural internet connectivity.

Wireless networking enables computer systems and peripheral devices to speak using The 2 way radio waves transmissions instead of over conventional network cabling. Using wireless Ethernet adaptors, any device able to be utilized on a normal computer network could be utilized on the wireless connection for task varying from file and printer discussing to multimedia and access to the internet.

Wireless Ethernet Technologies are layed out by some standards known as IEEE 802.11. Although other wireless technologies and methods exist, the term wireless is usually utilized in mention of the the IEEE 802.11 standards.

The communication methods for wireless networking are based on the Institute of Domestic Electricians (IEEE) 802.11 standard, which includes the 802.11a, 802.11b and 802.11g methods (although other standards are happening). Probably the most broadly used of these is 802.11b (Wireless-B), that is more reliable compared to faster 802.11a (Wireless-A) standard, and it is more cost-effective to create and operate too. Wireless-G or 802.11g, is really a more recent protocol that’s increasingly broadly adopted by suppliers because it is able to accelerates to 54Mbps as opposed to the 11Mbps of 802.11b products.

It’s no more rare to locate products like a walkie talkie that support the 3 standards, but generally, Wireless-G is made to be backwards suitable for Wireless-B products. Thus Wireless-B and Wireless-A products won’t use each other, nor could they be suitable for Wireless-G products.

Some producers offer models with dual-band (Wireless A & G/B) auto-switch way of greater communication versatility. Network organizers can plan their network deployment using a mixture of Wireless-B,G or perhaps a.

Wireless 802.11 standard utilizes the license-free rf bands round the 2.4GHz and/or 5GHz ranges. The 802.11b and 802.11g methods make use of the 2.4GHz band whereas 802.11a uses the 5GHz band. Wireless-B is undoubtedly typically the most popular standard, using the more recent Wireless-G (802.11g) and Wireless-A (802.11a) closing in fast.

Wi-FI or Wireless Fidelity is really a certification program established through the Wi-Fi Alliance to make sure interoperability of wireless products. Initially, the word Wi-Fi was intended as interchangeable with 802.11b, but more lately it’s extended to pay for any 802.11 network.

WLAN or Wireless Lan, is really a computer network -or part thereof- that includes wireless products. Inside a WLAN network, a regular LAN set-up could be extended to incorporate wireless products utilizing an entry way. Although wireless systems could be completely separate from conventional network, WLAN usually forms part of the existing wired network.

Wireless Transmission ranges vary greatly and decreasing the bandwidth will raise the coverage area, a standard 802.11b or 802.11g device will routinely have a variety of about 30m indoor or more to 120m line-of-sight outdoors. The primary reason for that variance between inside and line-of-sight coverage is the fact that walls along with other objects do slow down the wireless signal. Because wireless transmissions are really low frequency radio waves, they’ll pass through walls along with other solid matter relatively simple. As distance increases, the throughput decreases. It is because lower signal strength lead to dropped packets and create a general reduction in network efficiency.

Comprehending the technology in wireless and wireless LAN/WAN networking enables the planner the versatility of utilizing wired and wireless systems. You will find areas that wired systems can’t go because of distance, terrain or topography thus when the planner has understanding on wireless LAN networking, the more, faster and simple it’s to deploy a highly effective wireless network.

Focusing on how wireless LAN works will even assist you to plan deployment of the rural wi-fi access service. Wireless LAN is an extremely cost-effective solution for necessary internet connectivity needs in far, remote towns. WISP is a great and potential business in remote areas.

Either you utilize commercial “off-the-shelf” WLAN gadget, tweak and improve its performance by utilizing greater-gain outside antenna or purchase a true-outside lengthy-range Wireless LAN. For assured network performance, service-quality and fewer network down time, we advise while using latter.
