The recently enhanced Land-Cellular CDM-819s and CDM-819u CDMA-1xRTT cellular modem with either RS-232 or USB interface is the best choice for use in a broad range of M2M (machine-to-machine) wireless industrial communication applications. Land-Cellular modems have demonstrated their quality and reliability in security and surveillance, point of sale and ATM, vending machine, oil and gas pipeline and many other applications. The CDM-819 is based on the 1.2.0x version of the Kyocera RF module with support for multiple profiles and Static IP. Features like dual-band capability, support for IS-2000 data rates, Mobile IP (MIP) and Static IP (carrier dependent) means your communications needs will be secure today and tomorrow.
  • Dial-Up Networking interface (PPP) for intelligent devices with a TCP/IP stack for Packet Data connections to 1xRTT network for ATMs, Kiosks, Irrigation Control, etc.
  • Environmental monitoring by circuit switch data call from central landline modem bank to CDMA modem in field.
  • Security monitoring; uninterruptible wireless alarm call on intrusion, answers incoming data calls for test and status check by Alarm Company.
  • Gas and Oil monitoring equipment can call out on alarm conditions to a cell phone for emergency alert. Scheduled data collection from a central landline modem bank is handled by calling into the CDMA modems phone number with a Circuit Switch Data Call.
  • Asset monitoring of Tank Levels and Flood/Water Level Management with Circuit Switch Data and IP network control via PPP connections.
