TP-Link 300Mbps Wireless N 3G Router detachable 2T2R, 2.4GHz, 802.11n/g/b, UMTS/HSPA/EVDO Compatible 3G On-the-Go TP-LINK's TL-MR3420 3G/3.75G Wireless N Router allows you to quickly set up a 300Mbps wireless network on-the go and share a 3G/3.75G mobile connection. By connecting a UMTS/HSPA/EVDO USB adapter to the router, a Wi-Fi hotspot is instantly established allowing users to share an Internet connection anywhere 3G/3.75G coverage is available. So wherever you are you'll have a reliable wireless connection to accommodate your networking needs.   Always Connected Nothing is more frustrating than losing your Internet connection in the middle of your work. To avoid such interruptions and provide our customers with an always-online connection, TP-LINK introduces the TL-MR3420, a robust 3G/3.75G wireless N router with true 3G/WAN fallover capability. You can set the primary link as 3G/3.75G or WAN (xDSL/Cable). TL-MR3420 switches to the secondary link when your primary service is interrupted. Once the service is restored, the router will automatically fallback to the primary link-keeping your business online with the minimal interruption to users.  
  • Compatible with UMTS/HSPA/EVDO USB modems, tested in the field
  • 3G/WAN fallover guarantees an 'always-online' Internet connection
  • Wireless N speeds up to 300Mbps
  • Supports PPPoE, Dynamic IP, Static IP, PPTP, L2TP Cable Internet access
  • SST technology dramatically increases link robustness and stability
  • CCA technology enhances your signal stablility by automatically avoiding channel conflicts
  • Wireless security encryption is easy to setup, just push the QSS button
  • WDS wireless bridge provides seamless bridging to expand your wireless network
  • IP based bandwidth control allows administrators to determine how much bandwidth is allotted to each PC

Wireless LAN features
Top Wi-Fi standard Connection of this device is done via Wi-Fi in a high standard. Wi-Fi 4 (802.11n)
Wi-Fi standards The type of wireless local area network (LAN). It can be ad-hoc, where units in a network communicate peer-to-peer, or Infrastructure, where units communicate with each other via an access point A LAN interconnects computers in a small area e.g. home, school or office. 802.11b,802.11g,Wi-Fi 4 (802.11n)
Modulation Modulation is the process of varying one or more properties of a periodic waveform, called the carrier signal (High Frequency Signal), with a modulating signal which typically contains information to be transmitted. The aim of digital modulation is to transfer a digital bit stream over an analog bandpass channel, for example over the public switched telephone network (where a bandpass filter limits the frequency range to between 300 and 3400 Hz), or over a limited radio frequency band. The aim of analog modulation is to transfer an analog baseband (or lowpass) signal, for example an audio signal or TV signal, over an analog bandpass channel at a different frequency, for example over a limited radio frequency band or a cable TV network channel. 16-QAM,64-QAM,CCK,DBPSK,DQPSK,OFDM
