1. Huawei 5g data currency must be a gimmick to cheat some people on the network. Don't believe it
2. Building owners, different procts apply for different projects to provide different information
the information needed for RF is:
2 Sample (s) PCs 3-4 sets (complete set with accessories, frequency interval greater than 1m, need three prototypes of high, medium and low frequency launch and one common launch sample or fixed frequency software)
3 The technical specification includes the following contents:
a Frequency: indicate the frequency range or detailed frequency points
B Movement: working mode, such as FM, HFSS, DSSS, unps, GSM, CDMA, etc.
C Output power
4 User manual
5. BOM list of key components (PCB, wire, etc., UL file No.)
6 Block diagram (antenna should be provided, and the transmitting frequency should be marked at the antenna end)
8 Part layout
9 Circuit description is also called operational description
9. PCB silk screen diagram PCB laout diagram (printed wiring diagram)
10. Charger en60950 test report. En60950 report for adapter
11. Final hardware version, final software version
12. Engineering instruction BT of Bluetooth, WiFi molation for testing
13. Antenna specification (including gain, GSM, WiFi, BT, WCDMA antenna gain)
14, Need to provide cell specification)
15. UL cert for PCB board (flame retardant grade greater than or equal to V-1)
16. Doc countersigned / POA countersigned (when the report is completed)
if it is high-voltage procts, you need more information about key components of safety regulation!

3. bitcoin market can now be seen on professional software, such as the coin card I use now. I think it's very good. Most of the data are available and updated in a timely manner. I recommend you to download and use it
4. It's just one of the applications, but it has a unique and unique nature, but in the final analysis, it's still a virtual thing, a bit like game currency.
5. Bitcoin is a kind of digital currency based on blockchain technology, and the simple understanding of blockchain technology is an electronic currency account system realized through point-to-point. It can record every transaction record of bitcoin through the network, and it is decentralized. No one can change it without authorization, so it has a very stable security guarantee for its holders. Blockchain is an incredible great technology in Internet finance. Its inventor "Nakamoto Tsung" has just been nominated as a Nobel Prize candidate by the economic and financial circles. Pay attention to "digital assets and business value-added points training" on Weibo to learn more!
6. Bitcoin is a kind of network virtual currency, but it can be used to cash out, which can be converted into the currency of most countries. You can use bitcoin to buy some virtual goods, such as clothes, hats and equipment in online games. As long as someone accepts it, you can also use bitcoin to buy real-life goods
