Optical Line Terminal (OLT): terminal equipment for connecting optical fiber trunk lines.

Ethernet Passive Optical Network (EPON): the PON technology based on ethernet uses a point-to-multipoint structure and passive optical fiber transmission to provide multiple services over ethernet.

For convenience of understanding and explanation, the micro base station and the entry system of the TVWS frequency band provided in the embodiment of the present application are described in detail below with reference to fig. 1 to 3.

Please refer to fig. 1, which is a schematic diagram illustrating a basic structure of a TVWS frequency band micro base station according to an embodiment of the present application. The micro base station 100 includes: a wireless transmitter/receiver 101, configured to transmit/receive a signal of a TVWS frequency band according to an air interface protocol;

and a controller 102 for controlling the in-home bidirectional data exchange of the wireless transmitter/receiver 101.

For example, the air interface protocol may include, but is not limited to, an IEEE802.11 af protocol and an IEEE802.11ax protocol, which is not limited in this embodiment. Wherein, the IEEE802.11 af protocol supports 8MHz +8MHz carrier, and the bandwidth is 30 Mbps; when the carrier wave of 16MHz +16MHz, the bandwidth is 60 Mbps; and when the carrier wave of 4 × 16MHz is adopted, the bandwidth is 120 Mbps. The IEEE802.11ax protocol supports 40MHz carrier, the downstream theoretical bandwidth is 2.4Gbps, the upstream and downstream carriers are adjustable, the broadband service is balanced in two directions, and the live television programs can be watched directly through user equipment.

It should be noted that, in the embodiment of the present application, the micro base station 100 in the TVWS frequency band may be directly installed in a corridor and connected to the switch 103, as shown in fig. 2.

Further, in the embodiment of the present application, the TVWS frequency band may include, but is not limited to, any one of 470MHZ to 702 MHZ. Because the radio wave in the frequency range of the broadcast white band has the advantages of small free space propagation path loss, strong transmission and diffraction capabilities and the like, the equipment working in the frequency range has wider coverage range under the same power and lower cost.

Further, an Adjacent Channel Leakage Ratio (ACLR) of a power amplifier in the wireless transmitter/receiver 101 is greater than 60dBc, a power amplifier efficiency of the power amplifier is greater than 45%, and a transmission power of the wireless transmitter/receiver 101 is 100mW to 200 mW. Because the micro base station 100 of the TVWS frequency band is a fixed wireless broadband access device, it has higher power amplification efficiency and lower adjacent channel leakage ratio, and can complete coverage of the broadband of the user when the device transmitting power is in milliwatt level, except the set-top box area of the living room, other areas such as bedroom, dining room, study room and kitchen can receive the super high definition television program signal, thus solving the problem of single fixed access point in the wired user access mode, and meanwhile, the broadcast white band also has the advantages of high penetrability and low loss.
