CDMA (Code Division Multiple Access) is one of the major cellular mobile network types, up against GSM (Global System for Mobiles), and has been widely adopted by the majority of the mobile networks in the United States.
While 3G brought about faster data transfer speeds on GSM networks the CDMA equivalent is EV-DO; or Evolution Data Optimised, giving data transfer speeds a much-needed boost.
So in order to make use of these networks (which include Verizon and Sprint) for machine-to-machine (M2M) purposes a different type of module is required. This is why we stock a range of CDMA modules including the CE910 DUAL as well as EV-DO modules such as the DE910-DUAL.
Build reliable, cost-effective, low-power wireless control products that are applicable for industrial and commercial applications. The Zigbee Technology is a wireless control technology at a global standard used in wireless m2m networks.
Zigbee operates on the IEEE 802.15.4 radio specification and operates in bands including 2.4GHz, 900MHz and 868MHz.
The Zigbee protocol is designed to provide a secure and reliable wireless data solution.
The Zigbee platform has been designed to maintain a strong RF communication through hostile environments that are usually common in commercial and industrial applications.
