Sami Honkaniemi, managing director of Mentura Group, introducing an enhanced version of the company’s TETRA Management Suite, which will become available shortly. “In the new version they are becoming more integrated, more one product, and it provides more convenience to the end user. “What we are displaying here is
the TNIB Optimiser. We are gathering information about the network from the infrastructure side, but we are also monitoring the network from the radio interface side – so we are getting both viewpoints. And the Optimiser is a tool for analysing the air interface performance and validating that the network is actually performing as confi gured. If there is any kind of deviation – let’s say, you have a frequency plan with certain parameters, and handover parameters – we are validating those live in the network and telling if there is any kind of performance problem there. “So the Optimiser closes the
360-degree cycle of viewing. It’s like we are monitoring calls, we are receiving calls, getting a network performance indication, getting all data, and then we combine this with the air interface data and provide a real understanding
of what’s actually happening. So when the network operator is doing network improvement and optimization, they can move very quickly to the analysis because they don’t have to go collecting this information.”
Direct radio access A powerful feature of the Optimiser, he went on, is that it can collect fi eld strength information directly from any suitable radio, over the air. “If a user is complaining about coverage issues or bad signal, we can activate that RSSI and immediately his position will appear on the map and we’ll start collecting over the air from that specifi c radio, without him really even noticing. We can immediately get coverage information from different parts of the network. It minimizes test driving, or avoids it.” The other part of the suite is devoted
to subscriber management. “That’s very powerful, profi le-based provisioning, so you can generate batches of subscribers based on a standard profi le all at once”, Mr Honkaniemi said. “Say, 100 radios with that profi le: you can generate the radios and the subscriptions and allocate numbers and so on, making service provisioning very effi cient.” Already using the suite are countrywide
networks in the Middle East, in Mexico and in Mentura’s homeland, Finland. Also
Analysing TETRA system performance – Sami Honkaniemi, of Mentura Group
From Korea, Unimo technology brought its MU-1500MD series radio modem, which supports both packet-mode and circuit-
switched TETRA data with over-the-air encryption. GPS location reports can be called up on request. Providing one watt of RF output, the modem comes in versions for the 300, 400 and 800 MHz bands.
Described as the world’s fi rst dual-mode GSM+TETRA phone, Unimo’s compact MU-1000GSM has a full-colour screen, is built on magnesium alloy die-cast frame and is proofed against drops, vibration and water ingress (IP54). It weighs just 297g when fi tted with the standard battery. TETRA band coverage is 800 MHz (up to 1W RF output) or 380–400 MHz (at up to 3W), with DMO gateway support. The manufacturer adds that the unit’s TETRA department is IOP (interoperability) certifi ed against equipment from Motorola, EADS, Teltronic, Selex, Rohill, Damm and Rohde & Schwarz. WAP support is available as an option.

we believe that you shouldn’t separate the network management from management operations”, he added. “You must have this information under control in the same way as you know which unit is going where. And that is what we are providing.”
