New 4G M2M Router

Category : 产品文章, 伊林思产品FAQ

E-lins H685t is a new 4G/LTE router with wifi,built on components that meet industrial requirements , with a low price but with unlimited features.The router can be mounted on a DIN rail with a separate bracket . It is powered by 12 VDC and has a rich support for different LTE bands, it can communicate via LTE at 800, 900 , 1800, 1900 , 2100 and 2600 MHz. Is not 4G on the spot then transferred router to 3G and then 2G. As for 4G so the router has a theoretical maximum speed of 100 Mbit / s download speed and 50 Mbit / s upload speed , but also for 3G offers the great performance by up to 42 Mbit / s download speed and 5.7 Mbit / s upload speed.

In order to reach these speeds , use of dual external antennas , three antennas included in the package , two for 4G and one for wifi. Because the router has an antenna plug of SMA type antenna can be replaced with more powerful antennas , which can be an advantage in such fixed installations.

Introduction

The H685 series Cellular Router designed for establish a 2G/3G/4G cellular and Wi-Fi wireless network and share a cellular broadband connection. The H685 series Cellular Router enables users to quickly create a secure Wi-Fi (802.11 b/g/n) network and provide access to the Internet using a cellular network. By connect to cellular mobile network; an Internet connection can be accessed and shared virtually anywhere within a wireless broadband network.

The NEW H685 openwrt router adopted the latest developed firmware, which is much more powerful than before. The most  remarkable feature is OpenVPN, this means a lot.

OpenVPN’s use of common network protocols (TCP and UDP) makes it a desirable alternative to IPsec in situations where an ISP may block specific VPN protocols in order to force users to subscribe to a higher-priced, “business grade,” service tier。

 

When OpenVPN uses Transmission Control Protocol (TCP) transports to establish a tunnel, performance will be acceptable only as long as there is sufficient excess bandwidth on the un-tunneled network link to guarantee that the tunneled TCP timers do not expire. If this becomes untrue, performance falls off dramatically. This is known as the “TCP meltdown problem”

Besides, H685 added 700Mhz(B28) in its range this time, especially for Australia users.
