4FF: The next generation UICC

  1. 1. 4FF: The next generation UICCSource: Research In Motion UK LimitedSubmission Date: March 26, 2012Document Number: SCP(12)000070 ETSI SCP Plenary #54 | Sophia Antipolis, France | March 29-30, 2012
  2. 2. SCP #54 Sophia Antipolis | March 29-30, 2012 Two 4FF Candidates Apple Motorola, Nokia, RIMSCP(12)000007 SCP(12)000008 2
  3. 3. SCP #54 Sophia Antipolis | March 29-30, 2012 The joint 4FF proposalThis 4FF proposal is a compromise that enables new features (pick-out, retention feature, single header row, physically significantorientation mark) while maintaining existing manufacturingprocesses. 3
  4. 4. SCP #54 Sophia Antipolis | March 29-30, 2012 Assembly of the joint 4FF proposal Module drop-inMilled out or plastic molded cavity 4
  5. 5. SCP #54 Sophia Antipolis | March 29-30, 2012 Multiple Form Factor Card Distribution• ID-1 + Plug-in + Mini-UICC punch out cards have caused terminal returns by causing PIN stubbing (See C6-100233).• In the Apple proposal, based on thickness requirements, a Triple Punch-out is feasible which would continue this card distribution trend.• No UICC vendors would confirm at SCP TEC that they would not manufacture such cards.• RIM considers all double or triple punch out cards non- compliant to the ETSI and ISO specifications due to the punch out gaps.Predicted Result• Reader size and cost will increase in order to safely accommodate the non-standardized gaps introduced by these cards. 5
  6. 6. SCP #54 Sophia Antipolis | March 29-30, 2012 Use of Adaptors Situation: User has a phone which uses the Apple proposed 4FF, changes to a new phone which uses Plug-in or Mini-UICC and inserts the Apple proposed 4FF UICC using an adaptor.Known Issues• Adaptors with a UICC inserted have always proven to be thicker and out of spec.• Adaptors don’t hold the SIM card securely enough (contact bounce).• Adaptors can cause reader pin stubbing when being inserted or removed.Predicted Result• Increased device returns where the root cause is determined to be users changing to a device compatible with a larger form factor SIM Card. 6
  7. 7. SCP #54 Sophia Antipolis | March 29-30, 2012 Tray-style reader lock-in• Large majority of devices using 3FF readers incorporate a tray or drawer as part of their design. This is because the small size makes the card difficult to manipulate with precision.• The Apple proposal does not showcase any usability improvements over the previous form factors to enable a variety of reader implementations. • Lacks a pick-out feature such as the extra plastic that users pull on 2FF or the fingernail slot provided in the RIM/Nokia/Motorola 4FF proposal. • The retention feature in the RIM/Nokia Motorola proposal enables push-push readers and increases reliability of small parts with generous tolerances.• The 3x2 pad of the Apple’s proposal has the exact same footprint as the 3x2 pad in a 6 pin 2FF or 3FF reader.Predicted Result• Apple’s proposal will lock reader design down to the costly drawer or tray-style reader for the whole industry. 7
  8. 8. SCP #54 Sophia Antipolis | March 29-30, 2012 Terminal Miniaturization Estimated minimum logical board reader footprint for an 8 pin USB capable card (red)• The joint proposal brings real miniaturization Estimated minimum logical board reader footprint for a 6 pin card (blue) to terminal vendors.• The joint proposal enables the use of a single row header-style reader. This reader design significantly reduces the footprint on the logical board compared to the status quo footprint proposed by Apple.• While both proposals require an additional row of pins to support USB, the RIM/Nokia/Motorola proposal has an C4/C8 staggering feature. efficient staggered pin layout to enable an RIM, Nokia, Motorola Apple efficient reader design 8
  9. 9. SCP #54 Sophia Antipolis | March 29-30, 2012 Advantages of the joint RIM/Nokia/Motorola Solution• The RIM/Nokia/Motorola solution would provide for rapid market adoption and transition from the 2FF/3FF to the 4FF. • RIM’s solution allows for a wide variety of UICC reader solutions including the least expensive header and block style reader designs as indicated in SCPTEC(11)0175.• The RIM/Nokia/Motorola solution is designed to maintain the current UICC manufacturing processes and keep down costs for both the terminal and card vendors. • Allows the module “drop-in” and “glue-on” manufacturing process currently in use by all UICC vendors.• The RIM/Nokia/Motorola solution adds usability features to the UICC. The Apple proposal adds cost and risk to the terminal. 9
