Please explain in the area below why an STA is necessary:
Welink Communications is working with partner companies to develop equipment that will use LTE technologies, using Citizens Band Radio Service (CBRS) spectrum [3550 - 3700 MHz], also known as Band 48, using 3GPP terminology. As part of the technology validation, Welink plans to conduct a series of field tests with both EUD and category A at one or more locations. The testing will benefit the public interest by enabling the pre-commercial testing of new products outside of a lab environment but in a controlled and managed manner. In addition to the product development testing described above, Welink and partner companies intend to conduct separate and independent lab testing in a real-world environment at a Welink facility or at a vendor's facility using specifications developed by the WINN Forum and CBRS Alliance. This trial will consist of an aggregate of up to 20 small cells (category A or EUD) for all the trial locations. The CBSDs will use the transmission parameters and operate inside the geographic regions defined below. These tests will use base stations and user equipment operating in CBRS spectrum only. Although the devices are prototypes and have not completed formal equipment authorization, the equipment used in these trials will be compliant with FCC rules, per 2nd Order Report and Order. Equipment from multiple equipment manufacturers will be used in the evaluation testing. Welink has the ability to shut down all transmissions operated under the experimental license in the unlikely event any interference occurs.

Purpose of Operation
Please explain the purpose of operation:  Product development testing of CBRS equipment. Outdoor installations 2) Evaluation of end-to-end CBRS architecture 3) Evaluation of coexistence mechanisms with shared spectrum (GAA) and PAL spectrum 4) Overall evaluation of TDD-LTE using 3.5 GHz Field tests will be conducted in highly controlled field environment, in order to assist in the development of commercial products.
