Create your own LTE tests in 15 minutes with Anritsu’s RTD

Today we take an exclusive look in this blog inside Anritsu’s Rapid Test Designer (a.k.a. RTD) tool. RTD is a very powerful tool that can be used to design LTE tests for R&D purpose. RTD works in conjunction with Anritsu’s MD8430A. MD8430A has not very long back won the CTIA Emerging technology award.

For WCDMA/HSPA testing, Anritsu offered Protocol Test System (PTS) for R&D purpose. For LTE the basic tool is the RTD. The advantage of RTD as opposed to earlier generation PTS is that RTD is GUI based development environment that can speed up development and very little knowledge of test script development environment like TTCN-2 and TTCN-3 is required.

The RTD is a software tool that sits on top of a control PC. It controls the Signalling Tester (hardware) MD8430A. The diagram above shows the setup and connections of different components. The hardware (MD8430A) simulates Layer 1 (PHY), MAC, RLC and PDCP. The software (RTD) is used to simulate RRC and NAS.

When the tool starts up you are offered typical options as in case of any software. Once you have clicked on new test and provided it with a name, you are up and creating your own scenario.

The simple procedures already have a name defined but you can start giving meaningful names to complex procedures. Each name signifies the action it will be performing. For example Cell Configuration will be used initially to configure the parameters of the cell.

Clicking on the Cell Configuration will provide you with the possible options that can be used to configure the cells like the SFN Offsets, etc. All the channels that are necessary for a cell can be configured here.

Here is my attempt to randomly create something :)

And try sending some message like RRC Connection release. Didn’t quite work because it’s not in the right sequence but just shows the ease with which things can be done.

This is run time result of one of the test cases.

It may take few hours to get the hang of RTD, but once you understand how it works, you can start creating your own tests and scenarios at full speed. There are also example procedures available to get you started ;)

"The MD8430A is being used by LTE chipset manufacturers to ensure the quality of their products, speed time to market, and reduce design and production test costs." - Wade Hulon, Vice President and General Manager of Anritsu Company, Americas Sales Region.

3G Americas releases White Paper on MIMO (Smart Antennas)

3G Americas, a wireless industry trade association representing the GSM family of technologies including LTE, announced that it has published an educational report titled, MIMO Transmission Schemes for LTE and HSPA Networks as a tool to increase awareness of smart antenna systems – also known as multiple-input multiple-output (MIMO) technology – and help guide their deployments in HSPA and LTE networks within 3GPP’s specifications and technology standards. The 3GPP evolution continues to be the leader in standardizing the most advanced forms of multiple-input multiple-output (MIMO) antennas.

Smart antenna, or MIMO, technology is commonly defined as, the use of two or more unique radio signals, in the same radio channel, where each signal carries different digital information, or two or more radio signals that use beam forming, receive combining and spatial multiplexing (SM). Relative to a traditional 1x1 antenna system, a 2x2 MIMO system is expected to deliver significant cell throughput gain.

The MIMO Transmission Schemes for LTE and HSPA Networks report provides an overview and detailed information of the current and emerging MIMO techniques that significantly increase the performance of HSPA and LTE networks.

“Smart antenna technology has arrived and will be a vital part of mobile broadband communications,” stated Pantelis Monogioudis, Ph.D, of Alcatel-Lucent LTE-Advanced Technology Strategy. “It is an exciting time for smart antenna technology as 3GPP has provided the leading technical standards for MIMO that the industry will utilize to improve the capabilities of mobile broadband.”

MIMO was first standardized in 3GPP Release 6 (Rel-6), and was further developed in Rel-7 with spatial multiplexing for HSPA+ using Double Transmit Adaptive Array (D-TxAA). As the report highlights, the use of multiple antennas at both transmitter and receiver allows:

• Substantial increase in peak data rate
• Significantly higher spectrum efficiency, especially in low-interference environments
• Increased system capacity (number of users)

Based on simulation results presented in the report, it was shown that the relatively simple MIMO transmission scheme based on 2x2 closed-loop SM, at low user equipment (UE) speeds, can increase by 20 percent the downlink (DL) sector spectral efficiency relative to a single antenna transmission, as well as increase the cell edge efficiency by approximately 35 percent. More advanced antenna configurations can provide benefits that are significant for users that are receiving a strong signal as well as cell edge users.

The 3GPP Rel-8 LTE specifications, completed in March 2009, included the most advanced forms of MIMO of any standard in the industry, and now, 3GPP is studying even more advanced MIMO enhancements for inclusion in 3GPP Rel-9 and Rel-10 for LTE-Advanced.

The white paper, MIMO Transmission Schemes for LTE and HSPA Networks, was written by members of 3G Americas, and is available for free download on the 3G Americas website here.

Complex LTE IPR System

Markus Münkler, Vodafone Group R&D spoke about IPR Regime for LTE @ LTE World Summit, Berlin

Progress since 2005
•ETSI has improved visibility of standards essential IPR across its membership
•NGMN Ltd has produced indications of the total royalty burden of candidate technologies LTE & WiMAX
•Placed IPR royalty rates in the middle of the next generation mobile economy debate
•Raised the IPR discussions to the attention of the EU and other regulatory bodies
•Built a legally sound platform of trusted collaboration among technology stakeholders

Interim conclusion
•IPR transparency has improved among engaged industry stakeholders
•However, new challenges have emerged from outside the technologydevelopers
•Therefore, IPR royalties remain a stumbling block on mobile technology developments

Firefly for British Kids

A new mobile designed for kids, the Firefly phone, is set to launch in Britain later this year, but the four year-old target audience already has adults in uproar.

The Firefly phone, a tiny handset for toddlers which packs just five buttons including “Mum” and “Dad” keys, and extensive parental controls, has been a hit in Ireland, and it set to go on sale in the UK later this year.

But the phone has caused concern amongst parental groups, with Aine Lynch, chief executive of the National Parents Council going so far as to question “where parental responsibility is going”.
“Why would kids need to be contacted by mobile phone? Why are they not in the care of their parents, teachers or supervisors?”, she said.

Indeed. Still it could be amusing to see nursery lessons interrupted by the Nokia ringtone, and we’ve seen tweens rocking iPhones before so perhaps a controlled environment is better than nothing at all. And certainly more appropriate than the Penis phone. We’ll let you know if the Firefly phone leads to the downfall of civilization or not.


Surprisingly this phone was announced couple of years back, I cant see why its taking so long.

The French have already said no to such phones but we Britishers are much more tolerant (in all aspects ;) so you may find children using them soon.

Tim Dowling from the Guardian argues against it:

There can be no earthly reason why a child of four would need a mobile phone, but there must be dozens of reasons why it shouldn't have a Firefly. Here are just a few:

• It is not possible to conduct a fruitful phone conversation with a four year old, as you will know if you have ever tried.
• Four-year-olds rarely, if ever, have information to impart of such significance that it cannot wait until they are five.
• A Firefly costs £60. Without a sim card.
• Your child should always be in the company of a responsible adult who has a phone you didn't have to pay for.
• A four-year-old with its own phone will spend all day attempting to contact Pocoyo.
• Four-year-olds never hang up.
• 52% of children between the ages of five and nine already own a mobile. Chances are you will have to buy the child a phone next year anyway, and they won't want a pink toy that doesn't do YouTube.
• If you don't know where your four-year-old is, there's no point in ringing him. He doesn't know where he is either.
• For much less money you can get tiny T-shirts with your phone number and the word REWARD printed on them.
• Four-year-olds are enough trouble as it is. The last thing we want to do is give them is the means to organise.

Operators give Femtocells Thumbs up in Femtocells World Summit

AT&T Inc. has announced that it will launch femtocells nationwide by the end of the year, expanding the trial launch it’s been running since January.

"We will expand that into a marketing trial of the AT&T-branded 3G Microcell, which will be open to customers through our AT&T stores ... in a handful of cities,” said Gordon Mansfield, AT&T's executive director for radio access network delivery, speaking at the Femtocells World Summit in London. "We're on track for a full national launch by the end of 2009."

He also said the carrier was exploring ways to expand the femto opportunity beyond simply selling standalone home base stations that offload cellular backhaul from the macro network and boost bandwidth for cellular users. For instance, integrating a femto into other devices in the home.

Meanwhile, Vodafone UK 's surprise femtocell service launch announcement yesterday won't force T-Mobile International AG 's hand to launch a rival service in the U.K. or in any of its markets.

The German giant is sticking to its femto guns and does not feel compelled to take on the largest mobile operator by revenue with a commercial home base station service of its own, simply because Vodafone was first to market in Europe.

"We won't be pushed by that announcement," said Klaus-Jürgen Krath, T-Mobile's senior VP of radio networks engineering, speaking on the sidelines of the Femtocells World Summit in London today. "Let's see how they do in the market...

"There is not any firm launch plan that I can disclose now," he added.

T-Mobile has been busily testing and investing in femto technology for the last few years, but the operator maintains that there are still technical and marketing issues that need to be resolved before a consumer mass market solution is possible.

T-Mobile is a strategic investor in access point vendor Ubiquisys Ltd. and femto chip startup Percello Ltd.

According to French mobile operator SFR , France is a tough market for femtocells.

And one of the issues that makes the country extra special in Europe is the growing public concern about the health risks from cellular antennas and handsets, according to Guillaume de Lavallade, director of network marketing at SFR, who was speaking at the Femtocells World Summit in London.

WiFi hotspots have been disconnected in public libraries; there have been court actions to prevent the installation of cellular masts or have them removed when they're close to schools or homes; and the national government is investigating the health risk associated with masts and handsets, explains Lavallade.

"Introducing femtos in France in this environment is raising these questions," he says.

You can explain that the emitted power of femtos is 10 times less than that of WiFi, comparable to a DECT phone, and that 3G handsets emit less power when connecting to the femto than on the macro network, or that a network based on a femto architecture generates less power than a macro architecture, he says.

"It's difficult for an operator to take those facts and figures to the consumer," he says.

SFR has been trialing a femto from Ubiquisys Ltd. , which was spotted on a French Website recently.
