Waveshare RM500U-CN 5G HAT for Raspberry Pi Quad Antennas LTE-A Multi Band 5G/4G/3G

Involving or operating across two or more bands (see band entry 1 sense 5b) and especially wavelength or frequency bands a multiband radio.

A multiband antenna is an antenna designed to operate in multiple bands of frequencies. Multiband antennas use a design in which one part of the antenna is active for one band, while another part is active for a different band.

Refers to a mobile phone that supports the four major GSM frequency bands (850/900/1800/1900 MHz), making it compatible with all the major GSM networks in the world. The 850/1900 MHz bands are mainly used in the US, while the 900/1800 MHz ones are available in most other countries worldwide.

Conclusion. A multiband antenna for the LTE/GSM/UMTS band operation has been proposed in this paper. The proposed antenna, which consists of the MPIFA and folded-loop antenna, has four resonant frequencies. The antenna provides wide 6 dB return loss bandwidth at both the low and high bands.

Why quad band important?

A quad band phone running on the global system for mobile communications (GSM) network will be able to roam anywhere in the world where GSM service is available. This is an important feature because each GSM network uses different frequency bands.

Features:

1. Supporting RM500U-CN core module, supporting 5G and LTE-A multiple network standards, supporting 5G NSA and SA networking, supporting four major domestic operators
2. Integrate rich network protocols, support multiple drivers and software functions, and support Windows / Linux / Android and other operating systems
3. Onboard USB 3.1 interface, backward compatible with USB 2.0, can be used to connect to a computer, Raspberry Pi or Jetson Nano motherboard for high-speed 4G Internet access
4. Onboard M.2 B KEY standard interface, compatible with optional RM500U-CN / RM500Q-CN / RM500Q-GL series 5G modules
5. Onboard UART, PWR and RST control pins, built-in level conversion, support DIP switch enable, compatible with master controllers such as Raspberry Pi or Arduino
6. Onboard USB Type-C interface, which can be enabled by switch, can be used for external power supply to supply power to the module separately, so as to connect more loads, the power supply is stable and flexible
7. Onboard power switch, reset button and LED indicator light, easy to control the module power on and off and check the running status
8. Onboard two SIM card slots, dual-card single-standby, can be switched and enabled by AT command
9. Onboard high-efficiency power circuit that can output up to 3A
