UAE - New Cell Handset Requirements

Posted on September 24th 2015 by

We were advised by our local agent that UAE's Telecommunications Regulatory Authority (TRA) confirmed new mandatory cellular handset requirements in recently published Technical Specification TS040. These requirements are being developed in order to establish a "Public Warning System" which will use several channels to broadcast public warnings in emergency cases or disaster situations.  Technical requirements are below:

  1. The Handset should be configured by default to receive all Warning Notifications.
  2. Messages should support both English and Arabic languages.
  3. Message should be limited to 1 page maximum.
  4. An emergency alert message should be immediately recognizable. (Emergency messages shall be specifically recognizable as being an emergency message that cannot be mistaken for an ordinary message)
  5. The emergency warning message should stay on the display regardless of the user setting, until the message indication is cancelled by the user. It should be possible for the user to review the message at a later time.
  6. Handset should only be required to receive and present Warning Notifications in languages as presented by the Warning Notification Provider.
  7. It should be possible for the Warning Notification to be displayed on the handset upon reception and without any user interaction.
  8. The alerting indication for a specific Warning Notification should continue until suppressed by users' manual operation (e.g. by pushing keys). The frequency and duration of the continued alerting indication is mobile device implementation specific. This should not suppress the alerting indication for subsequent Warning Notifications.
  9. The handset should not support any capabilities to forward received Warning Notifications, to reply to received Warning Notifications, or to copy and paste the content of Warning Notifications.
  10. The handset should have the ability to present previously displayed Warning Notifications if requested by the user.
  11. The handset should be able to support concurrent reception of multiple Warning Notification.

These new requirements apply to all cellular handsets entering UAE beginning January 1, 2016.

Paraguay - 915-928 MHz Band Closed

Posted on September 15th 2015 by

Recently, we were advised by our local agent that the Paraguayan Authority, Comisión Nacional de Telecomunicaciones (CONATEL), is no longer allowing the 915-928MHz band for spread spectrum devices due to interference problems. Additionally, we've been advised that products (operating in this band and with an existing Paraguayan Type Approval certificate) may continue to operate until the existing Type Approval certificate expires.

On September 9, 2015, the Independent Communications Authority of South Africa (ICASA) published a Discussion Document regarding the use and licensing of the band 57 – 66 GHz (V-Band) and the band 71 – 76 GHz paired with the band 81 – 86 GHz (E-Band). This document is in response to requests from operators and equipment vendors for access to these bands and the need to create a regulatory framework which takes into account the specific features of these bands. ICASA encourages interested parties to submit their views on the Discussion no later than November 27, 2015. Link: Discussion Document On Use and Licensing Of E-Band and V-Band

The FCC recently announced an agreement with Canada to harmonise spectrum use along the US-Canada border in anticipation of the planned auction of frequencies in the 600 MHz band next year in the US. The Statement of Intent agreed with Industry Canada outlines a framework and timeline for repurposing TV spectrum for mobile broadband on both sides of the border. The agreement follows a decision on the Canadian government to allow mobile services in the 600 MHz band, using the same specifications as adopted by the FCC last year. Industry Canada and the FCC will jointly repack TV stations using the frequencies on the same timetable, freeing up spectrum for mobile services. The FCC said the agreement will significantly reduce potential interference for future mobile services along the border. The US reached a similar agreement with Mexico earlier this year.

On August 5, 2015, the FCC adopted new rules to address the long-term needs of wireless microphone users by providing for continued access to the 600 MHz band and expanding access to other bands. Wireless microphones play an important role in enabling broadcasters and other video programming networks to cover breaking news and live sports events. Wireless microphones also enhance event productions in a variety of settings – including theaters and music venues, film studios, conventions, corporate events, houses of worship, and Internet webcasts. 

Most wireless microphones today operate on unused spectrum in the frequencies currently allocated for TV broadcasting. Wireless microphones also operate in other bands, both on a licensed and unlicensed basis, depending on the particular band. Following the incentive auction – with the repacking of the television band and the repurposing of current television spectrum for wireless services – there may be fewer frequencies in the television bands available for use by wireless microphone operations.

Specifically, the new rules:

  • Provide more opportunities for licensed use in the remaining TV bands by allowing greater use of the VHF channels and permitting co-channel operations inside DTV contours without coordination if TV signals fall below specified threshold;
  • Expand eligibility for licensed use of the 4-megahertz portion of the 600 MHz duplex gap to include all licensed users in the TV bands (broadcasters, cable programming networks, movie studios, and operators at major sporting/concerts/theater venues); and 
  • Provide new opportunities for these licensed wireless microphones to operate on a secondary basis in three additional spectrum bands, consistent with the FCC's spectrum management goals – (1) access to significantly more spectrum in the 900 MHz band; (2) access to a portion of the 1435-1525 MHz band at specified times and places, subject to coordination requirements that protect critical aeronautical mobile telemetry; and (3) access to portions of the 6875-7125 MHz band.

Together with the rules adopted by the FCC today regarding unlicensed use of the 600 MHz band these new rules provide for efficient sharing of these bands to accommodate various wireless microphone users, while continuing to protect the licensed users of each of the bands.  Please contact Rhein Tech directly if you have additional questions or testing requirements. 

On July 31, 2015, the FCC published 393764 D01 UWB FAQ v01(Ultra-Wide Band Device Frequenty Asked Questions); this document provides answers to the following UWB FAQs: 

  1. What constitutes the bandwidth of a UWB emission for devices operating under Part 15?
  2. How is the UWB emission bandwidth determined?
  3. What portion of the UWB emission spectrum is required to be within the authorized frequency bands? Is it adequate for just the center frequency to be within the authorized band?
  4. Can a device be certified under the UWB rules if its emission bandwidth resides outside of the frequency bands identified for each UWB application but all associated emissions are below the prescribed limits?
  5. How are the emissions limits to be applied in determining compliance of a UWB device?
  6. Is any specialized test equipment necessary for performing UWB compliance?
  7. What compliance information should be included with an application for certification?
  8. What type of measurement antenna should be used for performing radiated emissions measurements on UWB devices when assessing compliance to the UWB rules?
  9. Is there a provision for operating wireless tank level gauges (e.g., level-probing radar) under the UWB rules?
  10. Are there standard measurement procedures available for use in demonstrating compliance of a UWB device to the applicable FCC Rules?
