With a bit of elbow grease and some creative thinking, you can set up a multi-connection network in your home on wheels that’ll have you surfing the web smooth as the highway.
The Need for Speed (and Reliability)
As any RV nomad knows, cellular data networks can be real fickle, especially once you get off the beaten path. And public WiFi hotspots at campgrounds often have less bandwidth than a duck tape slingshot. But with the right gear and setup, you can combine multiple internet connections for speed, redundancy, and reliability.
I’ll tell you how to:
- Use cellular amplifiers and external antennas to pull in signals from multiple carriers
- Create a wireless access point for connecting devices
- Bond multiple sources like cell networks, WiFi, and satellite for maximum bandwidth
- Automate failover and load balancing between connections
Stick with me and I’ll break it down so even a chicken plucker could understand it.
Why You Need Multiple WAN Connections
Now if you’re just checkin’ your email or scrolling through the Facebook every so often, a single cellular connection might suit you just fine. But for data-hungry tasks like streaming HD movies or video chat, you’ll want more bandwidth.
And cellular data drops ain’t no rarer than flies on cow patties. So having a backup source for when your primary goes out is critical. With multiple connections, you’ll stay online even if your cell signal fades or the satellite gets obstructed. Redundancy is your friend!
A Tale of Two Networks: WAN and LAN
Before we go much further, we best pause for a terminology tidbit. Now your RV network has two main parts:
- WAN (wide area network) – This connects your RV to the outside world through cell towers, WiFi hotspots, and satellites.
- LAN (local area network) – This allows devices within your RV to talk to each other and share the WAN connections.
The WAN fetches data from the web and brings it into your LAN. Kinda like a pack mule hauling supplies to a frontier campsite. Now let’s look closer at each section…
Expanding Your Wide Area Network
The WAN side is all about getting usable signals from multiple sources. That starts with amplifying feeble cell connections and positioning external antennas.
Cellular Amplifiers
You’re probably already familiar with cell signal boosters. They grab weak signals from nearby towers and amplify them for improved speed and reliability. But did you know you can parallel connect boosters from different carriers? With a multi-carrier setup, you get both expanded coverage and bandwidth bonding.
Some things to ponder:
- Antenna placement – Roof mounts give best line-of-sight to towers. Use high gain directional antennas to target sources.
- Booster connectivity – Ensure amplifiers have adequate PCI-E or USB ports for connecting modems from multiple networks.
- Carrierfirmware updates – Keep carrier-specific firmware on modems updated for compatibility.
- Overamplification risks – Boost only as much as needed or risk desensing the cell network. Start conservatively and increase gain as needed.
With the right gear, you can grab signals from three or more carriers at once for serious bandwidth potential!
WiFi Antenna Tricks
In addition to cell networks, strategically positioned WiFi antennas can help latch onto campground hotspots. For best reception:
- Use directional high-gain antennas to reach out toward sources. Omnidirectional whips are fine for general coverage.
- Mount antennas high with line-of-sight to where humans congregate. Many RV parks arrange sites in spokes around a common hub.
- Visually scan antenna orientation while watching signal strength for peak gain.
- Use parabolic dish antennas to focus signals from a single direction. These work great for targeting a specific hotspot.
With some trial and error, you can tune your setup to pull in the most signals from surrounding campsites. Just be mindful of your download limits!
Satellite Internet
Satellite internet like Starlink can provide truly remote connectivity. But dish placement is critical:
- For travel use, portability trumps all. Choose self-aligning dishes with easy setup. Automatic satellite switching is ideal.
- Visually scan for obstructions from tree branches, awnings, ladders, etc. Outages are no fun when you need reliable connectivity.
- Watch for data caps and throttling limits. Unbridled streaming can chew through precious allocations.
With the right gear and setup, even boondockers in the boonies can get functional satellite internet during stops. Just don’t expect fiber optic speeds while rolling down the highway!
Local Network Distribution
Alrighty, so now your WAN side is optimized to pull in multiple connections. But how do you share them locally and combine their power? That’s where your RV’s LAN comes in.
Creating a Local WiFi Network
Nearly all cellular amplifiers have a built-in WiFi router that shares the enhanced cell signal in your RV. Similarly, satellite internet dishes create a local hotspot for connecting devices.
With multiple WAN sources, your RV network could look like this:
- Cell booster 1 > Local WiFi Network A
- Cell booster 2 > Local WiFi Network B
- Satellite modem > Local WiFi Network C
Problem is, you want ONE unified local network to connect all your gadgets easily. Here are two good solutions:
Use WAN Ports for Chaining Routers
Most cellular and satellite routers have WAN ports to connect upstream to an existing network. Simply daisy chain your various routers into one master router via their WAN ports:
Cell Booster 1 WAN port > Main Router WAN port
Cell Booster 2 WAN port > Main Router WAN port
etc...
This bridges all the local networks together into one unified WiFi hotspot. Just be sure your main router has enough WAN ports for all sources.
Combine Networks with Mesh Routers
Instead of chaining separate routers, mesh WiFi systems like Netgear Orbi combine into a single seamless network. Set your satellite modems and hotspots into “bridge mode” to pass traffic to the mesh system. Voila!
Considering Load Balancing and Failover
Now you could just connect everything into one jumbled hotspot and call it done. But intelligently managing traffic between sources unlocks the true potential.
Load Balancing
This spreads bandwidth usage evenly across your links for fastest speeds and congestion avoidance. As one connection slows, traffic shifts automatically to another. It’s like opening multiple cashier lanes at the grocery store – traffic moves faster!
Failover
This designates a prioritized hierarchy of connections for redundancy. Lower priority links only engage if higher ones go down. It’s like your buddy with the pickup truck. Call him first for help moving houses. But if he’s busy, try your other friends before getting stuck.
Purpose built routers like Peplink Balance offer robust features for managing traffic intelligently across WAN links. Though cheaper consumer routers have some basic failover functions as well.
Prioritize your fastest and most reliable connections first, then fail down to backup sources as needed. Cellular and WiFi are prone to dropouts, so designate satellite as the final failover for true redundancy.
Bonding Cellular Connections with MIMO
Now if you really want to geek out, there are some super advanced techniques for bonding multiple cell networks together into a virtual fat pipe, multiplying your bandwidth.
This combines the unique virtues of each carrier – Verizon’s rural coverage, AT&T’s cities, T-Mobile’s speed – into an aggregated Voltron-like mega-network!
Introducing MiMo Antenna Arrays
The key technology enabling this cellular bonding voodoo is MIMO – Multiple Input, Multiple Output antennas. MIMO uses multiple radios and antennas simultaneously to multiply bandwidth.
By connecting MIMO-capable modems and antennas to different carrier networks, you can fuse their signals together for major performance gains.
It takes specialized gear, but you can potentially bond three or more LTE networks:
Speed and Reliability
With MIMO cellular bonding, you get explosive bandwidth potential coupled with the reliability of multiple independent connections. The whole becomes greater than the sum of its parts.
While not easy or cheap, this approach delivers fiber-like performance for the most demanding mobile network needs. We’re talking 100+ Mbps speeds! Of course with great power comes great data usage, so watch those caps.
For most RV use cases, failover and load balancing across separate links is plenty. But MIMO bonding is the pinnacle of mobile networking if you have need for extreme speed and redundancy.
Implementation Challenges
While tantalizing, multi-carrier bonding presents some challenges:
- Cost – MIMO gear, antennas, and unlimited data plans required
- Setup complexity – Precise antenna positioning and modem configuration
- Carrier cooperation – Networks use protections against unrestricted bonding
This is deep down the rabbit hole of cutting edge mobile networking. But with patience and technical savvy, the payoff is a robust redundant array even NASA would appreciate!
Final Thoughts
Well if you made it this far without nodding off, you’re clearly serious about getting properly connected out on the road! Once you get your network ducks in a row, you’ll be streaming, surfing, and video chatting even in the most remote boondocking locations.
