The advantage of using wireless data transmission module... Data transmission can be simply divided into two major types: wired (including the installation of optical cables, cables or leased telecommunication lines) and wireless (including the establishment of dedicated wireless data transmission system or the borrowing of CDPD, GSM, CDMA and other public network information platforms).     In...


Industrial-grade 4G router TCP/IP network architecture 1. Layering of TCP/IP network system   TCP/IP (TransmissionControlProtocol/InternetProtocol), transmission control protocol/Internet protocol. It was developed by the defense advanced research projects agency in the 1970s, and was later integrated into UNIX and popularized. It emerged in the 1980s as the Internet's...


The structure of 4G DTU The main function of DTU is to transmit data from remote devices back to the background center via wired/wireless. Different data transmission modes of DTU include all-network-connected DTU, GPRS DTU, WIFI DTU, CAN DTU and 4G DTU. Today, we will have a look at the structure and work flow of DTU.   To complete...

2.4Ghz WiFi Comparation

Category : 技术相关

WLAN communication criterion live through 802.11a, 802.11b, 802.11g and nowadays’ main 802.11n and 802.11ac.

802.11b 11Mbps
802.11 Super b 22Mbps
802.11g/802.11a 54Mbps
802.11 Super G 108Mbps
802.11 High Speed-G 125Mbps
802.11n 150Mbps
802.11n 300Mbps
802.11n 450Mbps
802.11ac 1200Mbps

450Mbps is the fastest WLAN in 2.4Ghz band. Comparing to 300Mbps wireless products, 450Mbps products have higher transmission band, provide high-efficient steam,more stability and wider coverage.
Real 450Mbps Wireless Products use three WiFi antenna. 150Mbps is two stream in 802.11N protocols. 450Mbps is three stream. One antenna sends and receives one stream, so 300M uses 2 WiFi antenna which is enough.
All E-Lins’ Cellular routers have WiFi feature option. H685 and H820 series use 150Mbps, and H700/H720 series use 300Mbps. H860 openWRT series has expansion WiFi slot for different band even for 450Mbps and 802.11ac dual band.
