Depplight carries on the PTCRB certification program all the year round, and we have a team of sales managers and project managers who have more than ten years' experience in dealing with this kind of PTCRB certification and GCF certification programs. Over the years, we have helped many listed companies to obtain PTCRB certification.
For example, in the test of SIM cards, there will be a series of SIM cards of operators to plug and unplug to check the adaptability of the products to different SIM cards of different operators.
For example, the OTA test will evaluate the omnidirectional transmission power TRP and the omnidirectional reception sensitivity TIS in the absence of reflection, and see that the performance of the transmitter and receiver of the product, which can be compared with the standard of the operator.
The following are 8 problems we often encounter in PTCRB certification projects that we often deal with, which we sum up.
These problems can be found in the deep light standard before doing PTCRB certification, and communicate well, which can not only speed up the testing progress, but also reduce some unnecessary tests.
The point is that it can save money.
1. Confirm the target operator and the frequency band to be used.
PTCRB certification is a North American network access test certification, which is related to specific operators. You need to know which operator you want to choose and which operator you want to take into account in advance, and then comprehensively consider and filter out the frequency bands you want to support.

1. Confirm the target operator and the frequency band to be used.
PTCRB certification is a North American network access test certification, which is related to specific operators. You need to know which operator you want to choose and which operator you want to take into account in advance, and then comprehensively consider and filter out the frequency bands you want to support.
For example, the target operator is AT&T, while the Verzion,B66 band can be added. Both operators support this band, but the B42 band is wasted and useless.
If you have difficulty in this step, you can seek assistance from the deep light standard. The deep light standard can help filter out the frequency bands of the target operators and help customers remove the useless carrier bands, so as to save testing costs and speed up the verification time. Because PTCRB certification has declared specifications, it needs to be tested without considering whether it is superfluous. If the unnecessary specifications are included, the testing fee will increase a lot.
2. The product has master and auxiliary double-card products. Prepare AT switching commands or upgrade software.
Some products are dual-card applications, but there is only one card in the network, so you need to prepare the AT command. During the test, you need to use the AT command to switch to the secondary card, activate the injection network, and verify the performance of the secondary card connected to the network.
3. Prepare FCC ID and CID.

3. Prepare FCC ID and CID.
FCC authentication, CID certification and PTCRB certification are three different certifications, but PTCRB certification requires that the list be submitted together. Before the PTCRB authentication can be provided in advance, we will verify whether it is valid or not.
4. The battery needs to meet the requirements of long-time testing.
In the PTCRB certification test, the OTA test is a general requirement. When conducting the OTA test, it is required to test TRP and TIS for a long time (several hours in a row) and high-power continuous connection with the base station. If it is cut off due to battery life (some products with poor heat dissipation will also seriously affect the working time of the battery), the whole test will be interrupted and the previous test data are invalid and need to be retested.
5. Confirm which features of the product are needed and which are not.
If some products have the function of MIMO, you need to inform PTCRB before evaluation. Once you do not need waiver, you need to inform PTCRB and have good reason to tell why waiver is dropped. The reason needs to be able to convince PTCRB fully, and it may bring trouble to actual sales in the future.
6. The product model had better be decided before certification.
PTCRB certification has relatively strict requirements on the model, and the model can not be changed at will. Once the fixed model is submitted to Request, it will produce a fixed Request # number, and the model cannot be changed. If you want to change, you need to resubmit the Request, which will involve the modification of the pics table and changes that may require testing. The Request number is not the same as the test report and cannot be certified.
7. After the hardware and appearance are confirmed, the software firmware version also needs to be confirmed.
Many people think that the software and hardware version is not important, in fact, PTCRB certification has something to do with the software firmware version, the firmware information in the software version number will be verified during the testing process, especially in the use of certified module products, this is a very critical information, rebrushing different firmware during the testing process may lead to the content of the previous test needs to be retested.
The software version number involves firmware. When many modules are certified, the frequency band and pics in the firmware brushed meet the requirements of major operators. The firmware brushed needs to meet the required version of the target operator, otherwise it is impossible to obtain the license of the operator. This step of the deep light standard can also provide assistance to check whether the requirements are met.
8. With the same design, a number of products need to be certified.
Decide which one to use as prototype certification (Initial) and which one to do modification certification (Variant). Let us know when you choose. If you are not familiar with this, you can communicate with the deep light standard to assist in the certification sequence of prototypes and modifications, in order to save test volume and test costs.
