According to the technology website PCWorld, Google has secretly tested its Project Loon hot air balloon networking project in the desert of Nevada, USA, which is the first time the company has licensed wireless band signals with hot air balloon testing.
Although Google declined to comment, local government officials confirmed that Google did test the hot air balloon project locally, and the government's public documents showed some hot air balloons in the local sky.
Google announced the hot air balloon networking project in June last year to help users in remote areas access Internet services. Google has said that they are flying hot air balloons about 20 kilometers above the ground to form a wireless network, but they are using an unauthorized 2.4GHz band.
In September last year, Cyrus Behroozi, head of Google's hot air balloon network project, submitted an application to the US Federal Communications Commission (FCC) for permission to use two licenses for 4G LTE in large areas of northern Nevada. Band, for hot air balloon networking test.
Google did not disclose the specific wireless technology they plan to use in the application, but revealed the approximate signal types, similar to LTE, WiMax and other peer-to-peer data transmission systems.
The Google is allowed to use the licensed band to test hot air balloons in northern Nevada. The two prerequisites are: first, get the consent of the local wireless broadband operator; second, not the Elko LTE base station in Nevada, 25 miles ( Tested within a range of approximately 40,000 meters).
In the application submitted to the FCC, Google said that the hot air balloon technology is still in the process of research and development, so it needs to be highly confidential and cannot be leaked. The Google Balloon is flying at a height of 20 kilometers, twice the altitude of a typical commercial aircraft, so it does not pose a threat to the air route during the flight, except for take-off and landing. The FCC asked Google to notify local airlines when it was flying.
Local officials confirmed that Google was conducting a hot air balloon test at Winnipeg Airport, but they refused to disclose details on the grounds of signing a confidential agreement.
Pluggable Terminal Block is made of two parts of pluggable connection. One part compresses the wire and then plugs it into the other part, which is welded to PCB. The mechanical principle of the connection bottom and the anti vibration design ensure the long-term airtight connection of the product and the use reliability of the finished product. The two ends of the socket can be equipped with matching ears, which can protect the connector to a large extent and prevent the poor arrangement of the connector. At the same time, this socket design can ensure that the socket can be inserted into the mother body correctly. The socket can also have assembly and locking positions. The assembly buckle can play a more stable role in fixing to the PCB, and the lock buckle can lock the mother body and the socket after the installation. Various socket designs can be matched with different insertion methods of the parent, such as: horizontal, vertical or inclined to printed circuit board, etc., and different ways can be selected according to the requirements of customers. Either metric wire gauge or standard wire gauge can be selected, which is the most popular terminal type in the market at present.
Our Pluggable Terminal block suit for 0.08mm² to 10mm² wire connection with 2.5mm to 10.16mm pitch. Flexible wire insert direction. connect direction and plug-in direction according to customer requirement.
