These call boxes regenerate the real world networks (like ATT, Verizon) inside the labs.When tests are performed in labs on the aforementioned call boxes it is called Lab testing.Usually the tests performed under sanity are : CS (Voice) call setup/end – Mobile Originated/Mobile Terminated, CS call maintenance (MO/MT) PS (data) throughput tests, Multi-RAB tests (CS+PS), SMS, MMS, Manual/Automatic network selection, Sleep mode (LP0) tests and flight mode tests among a few others. Sanity tests are tests performed to verify the general workability of a device.Most of the times device’s stability is tested with sanity tests. Generally when testing OTA, it is done under static conditions unlike driving conditions in drive testing.How is it different for OTA network from drive testing? Depending upon various operators like ATT, T- Mobile, Verizon and Sprint etc the product validation testing differs as per the operator’s requirements. Device testing is performed by operators and OEMs (Original Equipment Manufacturer) both.And from the view of different procedures, the testing comprises R&D testing, factory testing and certificate testing. The testing will be conducted on both hardware and software. Mobile-device testingfunctions to assure the quality of mobile devices, like mobile phones, Tablets etc.The equipments used for recreating live network scenarios are generally Anite, R&S, Anritsu and Spirent. Testing the device for stability on either Over The Air (OTA) network like AT&T, Verizon, T-Mo and others or on call boxes recreating the live network in a lab.
