ITU-T Question 26/16," Accessibility to multimedia systems and services", and ITU-T Question28/16, "Multimedia framework for e-health applications", of ITU-T Study Group16, would like to thank ITU-T IRG-AVA for sending us the LS on barriers to wireless connections for hearing aids and medical devices (our TD341/Gen, your IRG-AVA-1507-005).

Both Q26/16 and Q28/16 think that this is a general issue, possibly affecting many devices in the current market, as the spectrum in question is widely used by many devices, such as ZigBee and Bluetooth. In particular , Q28/16 fears that personal healthcare devices compliant to the Recommendation series H.81x ("Continua") may be affected by the situation described in the LS. Q26/16 concurs with Q28/16 that hearing aid devices may also be affected.

During our discussion, it came to our attention that ITU-T JCA-AHF has collected several documents on this issue at: http://itu.int/en/ITU-T/jca/ahf/Pages/201502-docs.aspx/.

–  Doc 191 Bluetooth Performance with 2.3 GHz LTE Interference Report-Issue 5t

–  Doc 190 ALD compatibility testing against 2.3GHz LTE, TDD signals at UK Ofcom Baldock June 2014; SUMMARY OF RESULTS

–  Doc 189 Brief Overview of 2.3-2.38Mhz to ALD Testing carried out at Baldock, 17-20 November

–  Doc 188 Update on testing between ALD and 2.3-2.4 GHz mobile phone systems

Q26/16 and Q28/16 would like request IRG-AVA to ask ITU-R WP5 to initiate a work on this issue, possibly taking into account the documents mentioned above.
