Ericsson and Kodiak in Europe Walkie Talkie-style push-to-talk push

2 way radio grande prairieWithout giving too much about this 2 way radio software free download short article, but I thought it fascinating and appropriate to what I’m now doing.

Some of the expert writers on the internet are at a really top level that i ponder if any of them have ever printed a paperback? well every so often i like to highlight these first-rate content pieces and here is one i thought was remarkable the other day.

Push-to-talk company Kodiak has struck a deal with Ericsson to sell the systems it is currently touting to the US market through American firm Cspire to European telcos. The pair are aiming to sell these services to both real mobile network operators and virtual ones.

The technology emulates an old-fashioned walkie-talkie using 4G, Wi-Fi and cloud services. Ericsson hosts the technology platform provided by Kodiak Networks in Ericsson’s Romanian data centre. The duo are targeting it at construction, hospitality, security, oil & gas, utilities, manufacturing, field services, education and transportation.

They are not aiming it at the mainstay of PTT – the emergency services – as being IP-based, it’s too laggy. The example the Tetra community loves to give is that of a commander with a team of snipers giving the order “don’t shoot”, and the first half of the message getting lost as a result of latency.

One of the great advantages of PTT is that it is one-to-many. The boss of a taxi company could let all his drivers know that Tower Bridge has lifted or that Hanger Lane is packed with traffic.

The Kodiak client runs on a number of phones, including Androids and iPhones, but it is those with dedicated PTT buttons such as the Samsung Rugby flip phone and the NEC Terrain which make the best use of it.

Unlike previous attempts to sell PTT, it’s not aimed at consumers. Around a decade ago, Orange decided that Kodiak’s 2G-based PTT was perfect for teenagers and that pushing to talk, message, or send a picture was the “new SMS”. Unfortunately the latency was appalling – of the order of a minute – and teenagers decided that having a conversation where only one person could speak at a time was not a good idea.

After having told handset manufacturers that they would not get any orders unless they built PTT based on the Kodiak codec into phones, Orange then gave up on the idea and neglected to order any of the expensive devices. Ericsson’s head of IT managed services, Luigi Migliaccio says that he thinks that attempt to sell PTT was before the technology was ready and that today there may be an opportunity based around the smartphone clients.

We have seen a respectable GSM implementation of PTT in Europe, this was GSM-R a standard particularly designed for Railways. Ericsson made the hefty 330g R250s PRO handset which supported it, but GSM-R never really took off – with even the targeted market of railways falling to adopt it. Many of the markets Ericsson is aiming at are currently catered for by Tetra, which is a technology that is running out of steam. The Tetra market is expecting to go 4G but wants updates to the specification. Migliaccio says that the updates are in the works and Ericsson will implement them when they are finished.

Kodiak claims a “sub-second” latency for its product but Tetra is specced to 200ms – although in practice systems often fail to achieve this. It would take some practical demonstrations to prove to the customers that not only was the latency acceptable, but that it didn’t lead to any loss of information.

Something the cloud-based solution won’t be able to do is fall back to a device-to-device walkie talkie. Tetra devices can, in the event of the failure of the network, communicate directly with each other.

Ericsson has higher hopes for the latest implementation and point to American success with Cspire, although this will to some extent come from the closure of Nextel, which offered a PTT service and had a strong blue-collar niche.

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 2 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.

Some of the trained writers on the web are at a really top level that i ponder if any of them have ever written a paperback? well every now and then i like to spotlight these brilliant content pieces and here is one i thought was fascinating the other day.

Hundreds of thousands of kilometres of oil and gas pipelines run across the most volatile and inhospitable areas of the world with vastly ranging temperatures and over difficult terrain.

Running pipelines above ground gives the advantage of significantly lower civil engineering costs, ease of visual inspection/leak detection and speed of repair, but it can also leave them vulnerable to environment conditions, accidental damage, sabotage, theft and piracy.

Keeping pipelines secure and sites running safely and efficiently in difficult operating environments poses constant challenges to the industry. The ability to communicate effectively with all cross functional teams and for them in turn, to communicate with each other reliably and immediately, not only improves operational efficiency, but also provides the means to react quickly in the event of an incident; which is why two way radios have become the communications backbone of the worlds oil and gas enterprises both in upstream exploration, extraction and production and downstream refining, storage, transportation and distribution operations.

With the advent of trunked digital two Way Radio systems, this ability to communicate by voice and data has been significantly improved in terms of quality, range, security and enhanced functionality.

Integrated Voice and Data Solutions

Designed and proven to deliver fail-safe voice and data communications to the worlds oil and gas industries, Kenwoods spectrum efficient NEXEDGE Digital trunked Two-Way radio solutions are fully scalable to accommodate large numbers of user groups spread across wide areas using wireless microwave or IP connectivity to ensure reliable service even when wired communications lines are rendered inoperable by adverse environmental conditions or acts of sabotage.
