Cellular gateway board takes up to five 4G mini PCIe cards, one 5G M.2 module, seven SIM cards

One Banana Pi customer asked them to customize Banana Pi BPI-R64 Linux router board based on MediaTek MT7622 WiFi processor as part of their “BPI 4.0 server” OEM/ODM customization service. Specifically, they were asked to design a cellular gateway board with the same five Gigabit Ethernet ports as on the original board, but adding five mini PCIe sockets and SIM card slots for 3G/4G cards, and one M.2 socket plus two SIM cards for a 5G module. Here’s the result! Banana Pi “GrassRouter” cellular gateway board specifications: SoC – MediaTek MT7622E dual-core ARM Cortex-A53 processor @ 1.35GHz System Memory – 1 or 2GB RAM Storage – 8GB eMMC flash, MicroSD card slot Connectivity Cellular 1x 5G via M.2 Key-B module (USB 3.0 or PCIe bus), 2x SIM card slots.

GSM repeater & signal booster extends 2G/3G/4G cellular coverage in your house or building

If your WiFi router range does not cover some of your rooms what do you do? You install a WiFi repeater or some of the more recent WiFi mesh networking solutions. What I did not know is that you can do something similar for cellular connectivity if you don’t quite get a reliable signal from your telco’s base station. Specifically, I’ve just come across a 900 MHz GSM repeater & signal booster that claims to be able to extend the 2G, 3G, and 4G cellular signal in a 100 to 300 m2 area, and sold for $59 on Banggood. Here are the specifications listed for the GSM repeater: Operating Frequency Band – GSM Uplink: 890-915Mhz Downlink: 935-960Mhz Gain: 70dbm Outdoor Directional Antenna Gain – 8dB Compatible with 2G / 3G / 4G cell phone signal Power Supply – 12V DC via 110-240V DC adapter Dimensions – 135 x 105 x […]

Orange Pi 4 SBC Gets a $16 4G LTE mini PCIe Card based on Rockchip RM310

Orange Pi 4 SBC is one of the most cost-effective Rockchip RK3399 SBC’s, as it sells for as low as $50 with 4GB RAM, Gigabit Ethernet, WiFi, and Bluetooth, HDMI 2.0 output, etc.. The board also comes with a 24-pin PCIe connector that’s not of much use on its own, so the company introduced a $4 PCIe adapter board providing access to a standard mPCIe socket and a SIM card slot so you could install your own. 4G mini PCIe cards can easily cost around $50 or more, but Shenzhen Xunlong Software has now launched its own 4G LTE mini PCIe card based on Rockchip RM310 module and sold for $16 on Aliexpress, excluding shipping. mPCIe card and RM310 module specifications: Frequency bands LTE-FDD – B1, B3, B5, B8 LTE-TDD – B38, B39, B40, B41 WCDMA – B1, B5, B8 GSM – 850, 900, 1800, and 1900 MHz Data rates […]
