3. © GSMA 2014 3 Introduction: GSMA Terminal Steering Group (1/2) Coordinates and drives terminal related matters in GSMA and beyond Membership – Over 65 companies – Operator, hardware and chipset vendor community worldwide Three focus areas: – Sharing of terminal related information – Alignment of terminal requirements – Alignment of field and lab test cases

4. © GSMA 2014 4 Introduction: GSMA Terminal Steering Group (2/2) Topics driven include : – Antenna Performance – NFC Requirements + Test cases – WI-FI – HD Voice Logo Terminal Requirements – Smartphone Network Efficiency – Smartphone Browser User Experience – 3GPP bearer field & lab tests – Battery Life Measurement Requirement Documents Test Cases / Certification Req. Inputs to industry Operators Vendors Industry groups + Certification

5. © GSMA 2014 5 GSMA TSG Antenna Performance: Background Mobile Handset design changed significantly in recent years – Antennas which were external moved inside the terminal – Antennas evolved to be light-weight and low-volume. Concerns raised about varying antennae performances and implications on user experiences In June 2010, GSMA Board & Strategy Committee agreed to actively address the topic – Conducted a study of Antenna performance on a number of handsets – Findings Acceptable levels were provided for approximately only 50% of the bands covered. Noticeable differences between left and right hand performance in some handsets – Noted related industry activities are non-existing or insufficient 3GPP define only absolute global minimum over the air (OTA) performance req. Test methods used and Antenna Performance values requested by the various operators differ widely, leaving vendors with fragmented requirements.

8. © GSMA 2014 8 TSG Antenna Performance: Activities (2) TS.24 Performance Requirements are based on Industry specifications from CTIA, 3GPP TS.24 Performance Requirements are validated against – Annual GSMA commissioned tests of market devices – Operator internal performance requirements and test results – TSG Vendor feedback TS.24 Performance Requirements – Can and are adopted/enforced by key operators around the world in their bilateral terminal requirements

9. © GSMA 2014 9 Antenna Performance: Labelling Scheme The originating issue and concerns about poor Antenna Performance and impact on the customer – Are understood and supported – Were also basis for GSMA work However, it should be noted, whilst it sounds so simple, the actual delivery of a labelling scheme is rather complex and carries risks 1. Realization 2. User / Market Impact 3. Resource Impact

10. © GSMA 2014 10 Antenna Performance: Labelling Scheme 1.Realization – It will be very difficult to sufficiently cater with one useful logo for all the different regional marketing & technical differences RF performance is defined per band, per scenario (head and hand, free space, browsing), per technology (2G, 3G, LTE) and against different test specs (3GPP, CTIA). RF performance is defined for receiving and sending; in case of receiving and where device carry more antennas, values can be defined with only one antenna switched on/both switched on. Different bands may have a different importance to operators in Europe Different use cases may have a different importance to operators Operators may want to accept variances in RF performances per scenario/bands/device model pending on internal priorities Difficult to keep up the logo evolution with evolving RF technology developments

11. © GSMA 2014 11 Antenna Performance: Labelling Scheme 2.User / Market Impact – Difficult to represent all applicable RF performances in one logo which makes sense to the user – Risk that a poorly delivered labelling scheme confuses users more than providing value – Risk of a strong lobby and, given the complexity, agreement on a logo could take quite some time and end up with underlying requirements which are much below those defined in GSMA and/or by indiv. operators today already. This in turn could negatively impact vendor efforts + eventually user experience. – Risk of a strict RF scheme negatively blocks innovation where new designs cannot test with existing test specs 3. Resource Impact – Resources of the key RF experts are very limited and much needed in industry work – to understand, assess and compromise on AP requirements – Risk of those handful of deep experts’ resources being diverted to follow/engage industry label activity

12. © GSMA 2014 12 Antenna Performance: Labelling Scheme Rather  Means other than a logo/label can address the problem more efficiently  GSMA members already actively aligning and engaging on global scale and across the industry  Global Certification Forum (GCF) supports reporting of Antenna Performance Requirements  Terminal vendors are taking action, also by introducing new technologies to enhance performance  Findings over the past two years are promising of increasing performance  More can be achieved, utilizing existing processes/fora to  Drive, communicate and adopt requirements  Share and make test results -based on common standards- available on wider scale

13. © GSMA 2014 13 TSG Antenna Performance: Labelling Scheme Conclusion: A regulated industry wide labelling scheme could prove difficult to implement in a way that provides real value to consumers and helps drive forwards the antenna performance of devices within the industry. However we do believe an industry initiated set of performance standards, based on testing methodologies approved by GSMA and implemented as part of the GCF could be a great value. We would therefore request and encourage the EU and especially also the Scandinavian countries to work with and help promote the ongoing work of GSMA to improve Antenna performance with Device Vendors.
