VZW 에서 Spirent system 을 3월말 validation 이후 추가적으로 2ea 시스템을 order 함에 따라 총 6개 Spirent LTE system 이 운용중에 있습니다.
3월에 validation된 항목으로는,
- Supplemental RF Performance
- Data Retry
- Inter-RAT SVD
- UICC CSIM Interaction [OTASP, OTAPA, MIP, A-12]
- LTE LBS Performance
이 있으며 3개 시험항목(InterRAT, Inter-RAT SVD, SVLTE, LTE LBS Performance) 은 Only Spirent solution만이 Validation 되었습니다.
4월 validation 과정 중에 있는 항목으로는,
- DATA Throughput
- eHRPD SC
이며 본 test Platform 도 곧 validation 이 될 것으로 기대합니다.

As already covered in the Spirent NewsFlash of April 4, Verizon Wireless’ CPE Lab issued a new release of its Test Equipment List for LTE devices at the end of March. A reminder of the key points:
• Spirent’s solutions have been validated for six of the Verizon LTE-Only and LTE Multi-Mode test plans, with two more Spirent solutions undergoing validation this month.
• Spirent has the only validated solution for four of the LTE Multi-Mode test plans (InterRAT, Inter-RAT SVD, SVLTE, LTE LBS Performance).
• The validated w2bi solution for UICC CSIM Interaction uses Spirent’s AirAccess
(2 x3452 V2s and a 3462).
• All of the currently-validated w2bi solutions for LTE Multi-Mode test themes include a Spirent 3452 V2 (along with hardware from other vendors).
• R&S and Anritsu have only two validated solutions each as of March – neither has had any solutions validated for LTE Multi-Mode test plans!
More great news from Verizon:
• Verizon’s CPE lab ordered two more LTE system upgrades on April 5.
• Verizon’s LTE Innovation Center in Massachusetts ordered our LTE RF Performance System during March. The objective of this lab is to bring non-traditional wireless-enabled products to reality. It’s important to note that the S3110B application was an influential part of their decision, which helps to support our ‘one-box’ proposition.
• As proof points to Verizon’s confidence in Spirent and the value we bring them, once we’ve delivered the April 5 orders, we’ll have a total of six LTE systems in Verizon - five in the CPE lab in Bedminster, NJ plus the new system in their Innovation Center.
• The five system configurations in the CPE lab will be as follows:
2. Data Throughput/Retry
3. All supported VZW test themes
5. Data Throughput/Retry/I-RAT
• So far as we’re aware, none of our competitors have more than two solutions in the CPE lab and in most cases we believe the CPE lab has only actually paid for our competitors’ ‘one-box’ solutions, not for their systems. Contrast this with Spirent, where Verizon has paid for all the systems/upgrades.
All this adds up to us establishing our leadership in this segment. When Verizon asked its vendors to prove their claims, only Spirent’s solutions, backed by a massive effort from our product teams, consistently delivered as promised. Now you can be confident of our leading position when you’re out selling.
AT&T publishes their LTE device acceptance test requirements in document number 17439 - a supplement to 10776. The Spirent solution availability status for the different test themes in 17439 is:
L1 Parametric Performance
L11 - L16 Data Performance: UDP, FTP, Latency
L21 Protocol Conformance
L22 RF Conformance
L24 RRM Conformance
Our solutions that address L1 and L11 – L16 are undergoing validation at AT&T this month, and we hope AT&T will move them to ‘Accepted’ status in 17439 within the next two months.
L8 Inter-RAT Active State Mobility
L7 Intra-RAT Active State Mobility
Lxx Device Aggression

All the success stories outlined above continue to pay off for us.
• It’s not all about Verizon and AT&T. Other major accounts who have recently ordered Spirent LTE test systems include Microsoft, Motorola, Qualcomm and RIM.
In conjunction with AT4, we’ve demonstrated protocol interoperability with two different TD-LTE chipset manufacturers, and have another demo scheduled for early April. All of the teams we met have indicated that no other test vendor has yet shown them working TD-LTE interoperability.
Note about TD-LTE: Also called TDD-LTE or “Time-Domain LTE”, this version of LTE will likely be deployed first in China and India. It also provides a way forward for current WiMAX operators who may decide to move over to LTE. In contrast to the FDD flavor of LTE now deployed in North America, TD-LTE uses a single frequency band (with time-domain duplexing) for both uplink and downlink signals.
So we’ll have TD-LTE and FDD LTE capability on the same platform, including initial TD-LTE support for the S3110B RF application and the first phase of conformance. We expect to have a beta release of S3110B for TD-LTE this month, well ahead of our competitors.
Our team has also shown working LTE-UMTS Inter-RAT (both Idle and Connected mode handovers) using eAirAccess. From the feedback we’ve received, it appears we’ve not only beaten our competitors to this milestone, we are actually ahead of most UE developers as well.
Since we have already proven our capability here, chipset providers including Icera, Intel/Infineon, ST Ericsson and Qualcomm have all expressed interest in testing with Spirent when they are ready.
