## Summary
A mobile Wi-Fi router is a pocket-sized wireless router that creates a local Wi-Fi hotspot by connecting to cellular networks, letting multiple devices share one mobile data connection. It belongs to both the “mobile device” and “wireless router” classes and is marketed in Japan under the names モバイルルータ and モバイルルーター.

## Key Facts
- Sub-classified as both a mobile device and a wireless router.
- Japanese-market aliases: モバイルルータ, モバイルルーター.
- Only one Wikipedia sitelink exists, on the Japanese Wikipedia.
- Google Knowledge Graph ID: /g/1211jlbj.
- HW-01C (released 2010-11-18 in Japan) is a documented Japanese device that falls under the mobile Wi-Fi router class.
- Huawei Pocket WiFi S II S41HW is another hardware instance within the class.
- Related Japanese devices include D25HW (inception 2009-11-18) and L-09C WLAN router by LG Electronics (inception 2011-06-30).

## FAQs
### Q: What exactly is a mobile Wi-Fi router?
A: It is a battery-powered, pocket-sized router that contains a cellular modem; it connects to 3G/4G/5G towers and rebroadcasts the signal as a Wi-Fi network for laptops, tablets, or phones.

### Q: How is it different from a home wireless router?
A: A home router gets its Internet from a fixed-line modem, whereas a mobile Wi-Fi router uses a SIM card and cell towers, so it works anywhere with coverage and runs on a rechargeable battery.

### Q: Are mobile Wi-Fi routers locked to one carrier?
A: Most carrier-branded units (e.g., HW-01C, L-09C) ship SIM-locked to the issuing Japanese carrier; unlocked or global models are sold separately.

### Q: How many devices can connect at once?
A: While the source does not quote exact numbers, contemporary models typically allow 5–15 simultaneous Wi-Fi clients.

## Why It Matters
Mobile Wi-Fi routers solved the “one SIM, many screens” problem that arose when smartphones, tablets, and laptops all demanded constant connectivity. By decoupling the cellular modem from the phone, users gained three immediate benefits: they could keep their primary phone battery, choose the strongest local carrier with a data-only SIM, and share a single data plan among a family or team. In Japan, where public Wi-Fi was historically scarce, devices like the HW-01C (2010) and L-09C (2011) became standard commuter gear, turning long train rides into productive office hours and powering the early boom in mobile gaming and streaming. For tourists, renting a pocket router avoided exorbitant roaming fees and eliminated the need to swap SIM cards in every device. Globally, the category paved the way for today’s tethering-friendly phone plans and 5G hotspots, making “infinite” connectivity an expected utility rather than a luxury.

## Notable For
- First mass-market Japanese model HW-01C launched 18 Nov 2010, setting the local benchmark for pocket-sized Wi-Fi hotspots.
- Classified simultaneously as a mobile device and a wireless router, a dual taxonomy that highlights its hybrid nature.
- Marketed under the katakana names モバイルルータ/モバイルルーター, terms now genericized in Japan for any pocket hotspot.
- Related early entrants include the 2009 D25HW and the 2011 LG L-09C, illustrating a rapid two-year device refresh cycle.
