Puck Antenna 4G Through-hole Mount Antenna

Description

What is Puck Antenna 4G Through-hole Mount Antenna?

The through-hole mount antenna Puck Antenna 4G CTRF-ANTENNA-EX-7027-4615-SMA-2M item is a dome antenna manufactured by C&T RF Antennas Inc that comes with a 4G network LTE frequency 698-960MHz, 1710-2700MHz, 5dBi,7dBi high-gain, 1 meter RG 174 cable antenna extension, a through-hole screw-mounted way for an easy installation.

C&T RF Antennas Inc provides indoor-outdoor 4G LTE antennas with many antenna types such as Dipole Antennas, Whip Antennas, Marine Antennas, Router Antennas, MIMO Antennas, Combo Antennas, PCB Antennas, FPC Antennas, Spring Antennas, Sector Antennas, Yagi Antennas, etc.

C&T RF Antennas Inc provides RF antennas with other antenna radio frequencies such as 169MHz, 230MHz, 315MHz, 433MHz, 868MHz, 915MHz, Lora, NFC, VHF&UHF, NB-IoT, ADS-B, GSM, Wifi 2.4GHz, 5.8GHz, 2G 3G 4G LTE, GPS, GNSS, 5G NR, UWB, etc.

4G high-performance antenna receiver

The 4G mobile communication system puts a high requirement on the receiver. The SHANNON theorem gives the minimum SNR required to achieve reliable transmission of capacity C in the channel with a bandwidth BW.

According to the Shannon theorem, it can be calculated that if the channel bandwidth is 5MHz, the data rate is 2Mb / s, and the desired SNR is 1.2dB; for the 4G system, the data is transmitted over the 5MHz bandwidth to transmit 20MB / s data, the desired SNR is 12 dB.

It can be seen that for 4G systems, due to high rates, the performance requirements of the receiver are much higher.

What is a 4G LTE HARQ technology?

The HARQ technology in LTE is mainly the selection of coded data bits retransmission at the system side and the merging of physical layer retransmission data at the terminal.

Layer retransmission data merging.

Here involve two aspects, one is the automatic retransmission request is ARQ technology, and the other is the forward error correction technology FEC. can also be said that

HARQ = ARQ + FEC

FEC is a coding technology, the role of coding is mainly to ensure the reliability of transmission, with automatic error correction The ability to automatically correct errors.

For example, if I want to transmit message 0, I can send 0000, and if interference is received and it becomes If I receive interference and it becomes 0001 or 1000, FEC can correct it to 0000, thus increasing the error tolerance, while sending only a 0 If the interference becomes 1, it will cause a false code.

If the receiver receives 1100, the 1s and 0s are the same. As many as 1s and 0s will be considered as a wrong code, which will request retransmission and trigger an ARQ.

The ARQ technology is to receive the information, it will be verified by CRC check bits, if the error is found or If the packet is found to be wrong or not received at all, it will return to NAK and ask for retransmission, otherwise, it will return to ACK to show that it has been received.
