The necessary set of equipment for high-quality Internet in the car

Question

Do it yourself

Dear Khabrovites!

Please tell me who had experience or is familiar with the solution of such a problem:

There is a car that constantly moves from one city to another, which needs constant high-quality Internet. In different cities, on different sections of the route, and even in the same city, but in different areas - all mobile operators work differently. Someone is better, someone is worse, someone gives a confident 3G signal, and the other in the same place is barely EDGE. In some places, LTE works perfectly.

I would like to build a small set of equipment in the trunk of a car, in the form of:

1. Wi-Fi router with the ability to plug in several SIM cards from different operators at once (preferably with LTE support), and so that the Internet is distributed the best one (ideally), or switched via the web interface
2. External antenna to amplify the signal (or amplifier separately), which one is better, which brand …

I will be glad to any proposed options.

Thanks to all!

Answer 1

2-4 phones turned on in WiFi Tethering mode and plugged into power. Bad connection? Switched to another wifi.

Answer 2

I'm just thinking about a similar task, but in Ukraine, you can get by with one operator. I looked at the curious mifi router Sierra W802 from the equipment . It also has GPS, but you can use it only when the router is connected to the PC like a regular modem, until you fully figure it out.

Answer 3

While the bottom line is, knowledgeable people suggested this device:
Robustel R3000 is an industrial 4G router with two SIM cards for LTE / HSPA / UMTS / EDGE / GPRS networks.
Reliable 4G R3000 router is designed to receive/transmit data via cellular networks in M2M systems.
Special Features:
Dual SIM redundancy for uninterrupted cellular coverage, supports 4G.
Antenna diversity method to improve transmission performance
Two Ethernet ports, can be configured as 2 LAN or 1 LAN - 1 WAN (supports wireless WAN and wired WAN redundancy).
1x RS232, 1x RS485, 1 console port, 2 digital inputs, 2 digital outputs, 1 Hi-Speed ​​USB up to 480Mbps.
6 LED indicators show network status and signal strength (RSSI).
Wide range of input voltage — from 12 to 70 V, and operating temperatures -40°С…+70°С.
Metal housing with the possibility of mounting on a DIN rail or wall, also with additional grounding.
Network protocols PPP, PPPoE, TCP, UDP, DHCP, ICMP, NAT, DMZ, RIP, OSPF, DDNS, VRRP, HTTP, HTTPs.
VPN tunneling: IPSec/OpenVPN/PPTP/L2TP client/server, GRE, DMVPN.
Management via Web, CLI, SNMP, SMS.
Supports Modbus/RTU to Modbus/TCP.
Always "on-line", "waking up" by SMS or during a specified time of day.
Automatic reboot via SMS or at a specified time of day.
Remote configuration via SMS.
Software update via Web-interface.

And connect any Wi-Fi from it.
Everything seems to fit, but you still need to choose the right antenna so that when driving at speed there is the most confident signal reception.

Answer 4

Convenient mobile antennas are made here - connect.remo-zavod.ru . Sold in many places. They are not expensive, while in the country where there was only an edge, the black grouse confidently catches 3G.
