We are now inquiring about the shielding instrument project of Hubei Province Personnel Examination Institute.
I. Project Name: 5G Shielding Instrument Project
2. Budget amount: 100,000
Third, the purchase quantity: 50
Fourth, procurement requirements:
1. Pass the spectrum analyzer test, the working frequency includes:
★ (1) Working frequency (required frequency band)
870 MHz-880 MHz Telecom CDMA / LTE
930 MHz-954 MHz mobile GSM / FDD / NB
954 MHz-960 MHz Unicom GSM / LTE
1805 MHz-1830 MHz mobile DCS / LTE
1830 MHz-1850 MHz Unicom DCS / LTE
1860 MHz-1880 MHz Telecom LTE-FDD
1885 MHZ-1920 MHZ mobile TD-S / TD-LTE / FDD-LTE
2010 MHz -2025 MHz mobile TD-SCDMA
2110 MHz-2130 MHz Telecom LTE-FDD
2130 MHz-2170 MHz Unicom WCDMA / FDD
2300 MHz-2320 MHz Unicom TD-LTE
2320 MHz-2370 MHz mobile TD-LTE
2370 MHz-2390 MHz Telecom TD-LTE
2555 MHz-2575 MHz Unicom TD-LTE
2575 MHz-2635 MHz mobile TD-LTE
2635 MHz-2655 MHz Telecom TD-LTE
(2) Working frequency (important frequency band)
2400 MHz -2484 MHz 2.4G WIFI
5725 MHz -5825 MHz 5.8G WIFI
3300 MHz-3400 MHz 5G Band 1
3400 MHz-3600 MHz 5G band 2
4800 MHz-5000 MHz 5G band 3
2. There is no interference to the uplink reception of base stations of various standard bands, which can be analyzed and verified through the background statistics of the base station.
3. Can set interference frequency for different frequencies.
4. In order to adapt to the size of different shielded areas and reduce the impact on unshielded areas, the output power requirements of the device are adjustable with 30dB as the reference.
5. Support remote network management function, support remote switch equipment, timing switch, shielding power adjustment, real-time monitoring and alarm reporting, etc .;
6. Support wireless network remote management, connect via base station and background management platform, realize remote management based on base station.
7. The downlink masker distinguishes the uplink and downlink signals by synchronizing with the LTE base station to ensure uplink without interference. The masker must have a synchronization failure protection function, that is, in order to prevent large-scale network failures, the masker can automatically restart after it loses synchronization with the base station, and the signal transmission is turned off after 5 restart failures.
8. Support joint networking of multiple devices, and realize device synchronization through networking to cope with the problem of out-of-step of a single device (when combined networking, no time slot interference between devices is generated).
9. Built-in power adapter and antenna.
10. The volume of the equipment is not more than 0.025 cubic meters, and the length of one side is not more than 0.5 meters. It supports wall-mounted installation and desktop placement.
11. The TDD system runs stably without out-of-step conditions.
(1) Suppliers that comply with Article 22 of the Government Procurement Law;
(2) Have the status of an independent legal person, and provide the Business License, Tax Registration Certificate and Organization Code Certificate.
Seven, procurement methods: inquiry
8. Inquiry document submission time: the completed "Public Procurement Inquiry Form of Hubei Provincial Government" (with attachments downloaded by yourself), equipment samples, legal representative's identity certificate or original legal representative's authorization letter (with official seal) ), From December 18th to 20th, 2019, from 8:30 am to 11:30 am, from 2:00 pm to 5:30 pm, the appointment will be delivered to No. 1 Donghu West Road, Wuchang District, Wuhan City Room 1516 of the Social Security Building. Suppliers who fail to register according to the above requirements within the above time will not be eligible to participate in the project inquiry.
