Industrial Level 7-Mode 4G Routers
Product Overview

The KR2201 series industrial level 7-mode 4G routers, based on MIPS 400MHz processor, and featured with built-in 512M DDR2 SDRAM and 128MB Flash support 7-mode 4G wireless communication to meet the demand of high speed communication of field devices.

The KR2201 industrial 4G routers are equipped with a 10/100Mbps adaptive WAN, a 10/100Mbps adaptive LAN, a Console port, and a DI/DO port.  They also support IEEE802.11 b/g/n and GNSS selections. The 4G module of KR2201 series supports 7 communication modes, including WCDMA, EVDO, TD-SCDMA, HSPA+, TDD LTE, and FDD LTE, as well as compatibility with both CDMA1x and EDGE/GPRS. The upstream speed and downstream speed of the KR2201 can reach 50Mbps and 100Mbps respectively, and the transmission rate of WLAN can reach 300Mbps. The KR2201 series also provides dual SIM cards and dual redundant power inputs. The features of strict EMS protection and wide operation temperature range ensure the operating stability in severe environments.
