Model 210M industrial radio

Long Range Wireless Ethernet Radio with Serial Port

Equipped with one Ethernet port (10/100/1G) and one independent Serial RS-232C dataport, ESTeem Model 210M industrial radios are specifically designed to withstand the most rigorous Industrial, Public Safety, and Federal applications where the mid-band VHF is needed for terrain coverage. The Model 210M narrow band licensed long-range Ethernet radio features selectable Quadrature Amplitude Modulation (QAM) that delivers up to 64.8 Kbps of data rate over distances greater than 10 miles in high noise environments, depending on the antenna used. The 210M’s internal Digi-Repeating feature makes Wireless networks over large geographical areas a reality. A Client Mode feature allows the 210M Ethernet radio to be used in mobile applications for roaming under a 210M RF canopy.

Software Features

  • High Security AES Encryption. 210M industrial radios uses the high-security 128-bit AES-CCMP required in most municipal, public safety and federal applications.
  • Network Optimization. Enhanced network operation through limited bandwidth is possible using networking features such as Static ARP Tables and IP Address Whitelist.
  • Enhanced Network Operation. Support for VLAN pass-through and network optimization is included to support enhanced network functionality.
  • Internal Digital Repeater Capability. Used as a series of digital repeaters, the 210M long-range radio modem can extend its range over line-of-sight obstacles to cover large geographical areas.

The Model 210M is well-suited for use as an Ethernet radio in long range wireless bridge applications and as a serial radio in point to multipoint networks as well as a wide range of other modes of operation.
