Network Setup for BoxPhone
Sikrid TeamSikrid Engineering TeamLAN, Wi-Fi, IP, and bandwidth — what to think about before you scale
How the network fits in
Every device in a BoxPhone fleet needs three things:
- Internet (over Wi-Fi or proxy)
- A connection back to the host PC (USB or ADB-over-TCP)
- Its own IP address
Once you go past 50 devices, consumer routers start having a bad time — DHCP tables overflow, the NAT pool runs out, throughput drops.
What each piece does
Router
Pick one that can handle:
- 100+ devices connected at the same time
- VLAN configuration
- Static DHCP / IP reservation
- QoS — so you can prioritize traffic
We recommend Ruijie EG series, MikroTik RB series, or UniFi USG/UDM. Not the free router your ISP gives you.
Wi-Fi vs LAN
| Wi-Fi | LAN | |
|---|---|---|
| Stability | Medium | High |
| How phones connect | Native | Via USB tether |
| Scaling to 100+ | Multiple APs needed | Use a switch |
| Best for | General BoxPhone use | Heavy automation |
Most setups land on Wi-Fi because Android just works with it. But you do need enterprise-grade APs to make it stable.
Bandwidth
Rough numbers to plan around:
- A device scrolling normal content: ~0.5–1 Mbps
- A device watching a live stream: ~2–3 Mbps
- A device uploading video: ~3–5 Mbps
100 devices on a mixed workload peaks at around 150–200 Mbps both directions — so 500/500 Mbps fiber as the floor.
What you need to put together
- Internet line — 500/500 Mbps fiber or better
- Enterprise router — handles 100+ devices
- Wi-Fi APs — business-class like UniFi, TP-Link Omada, or Aruba — 1 AP for every 30–50 devices
- Switch (if using LAN) — Gigabit switch with VLAN support
- Static DHCP — pin a fixed IP to each device so debugging stays sane
- Proxy management — software that hands a different proxy to each device (see What is a proxy?)
Where it usually breaks
- Consumer router that can't keep up — DHCP overflows at 50 devices
- Wi-Fi channel congestion — multiple APs sitting on the same channel
- NAT port exhaustion — 100 devices × lots of sessions = the router runs out of ports
- ISP throttling — some ISPs throttle quietly without telling you
- Not setting up Static DHCP — when something breaks, you can't tell which IP belongs to which device
Wrapping up
The network isn't something you bolt on later — it's the foundation everything else sits on.
Spend the money once and do it right — it's a lot cheaper than rebuilding the whole thing after you outgrow it.
FAQ
01Can I use a regular home router?+
Sure, up to 5–15 devices. Past that, consumer routers start running into DHCP table overflows, NAT pools running out, and throughput dropping. Move to enterprise gear before it bites you.
02How much bandwidth do I need for 100 devices?+
Peak around 150–200 Mbps on a mixed workload. We'd say 500/500 Mbps fiber is the floor — live streaming and uploads in particular need that upload headroom.
03Wi-Fi or LAN — which is better?+
Most setups use Wi-Fi because Android handles it natively. But you do need enterprise-grade APs, roughly 1 AP per 30–50 devices. If you're running heavy automation, LAN is the better call.
04Do I have to set up VLANs?+
Past 50 devices, yes. VLANs split your device groups apart so one group's problem doesn't take down everything, and debugging gets way easier.
