Latest H685 Openwrt LTE Router for Australia

Category : 产品文章

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.

E-Lins’ mobile data products are widely used in more than twenty industrial fields, such as power control, water schedule, traffic, oil field, weather forecast, environmental protection, street lamp control, post, bank and many other areas

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.
