Wireless Sensor Design Challenges: Gateways

Mon, 07 Oct 2013 15:00:15 +0000

Wireless sensors are intended to operate via short range wireless communications. That's why they're called "body area" networks. Due to power consumption constraints, wireless sensor radios typically don't operate as 802.11 a/b/g/n radios used in enterprise networks. The reference designs from the manufacturers of radios intended for wireless sensors often indicate a range of a […]
