Mobile Phone Networks
and the Physical World
Ethernet and WiFi are handy ways to talk to people and things on the
Internet, but there's a great big chunk missing: the mobile telephone
network. Nowadays, telephony and the Internet are so intertwined that it
doesn't make sense to talk about them separately. It's getting increasingly
easy to connect physical devices other than mobile phones through mobile
phone networks. In this chapter, you'll learn how to connect these two
networks, and when it's useful to do so.
ohai lion, how r u??? txt me l8r!!!
This lion can send you an SMS. Groundlab, in conjunction with Living with Lions and Lion Guardians, developed
this tracking collar that utilizes a GPS/GSM module to transmit lions' locations via SMS to researchers and Maasai
herders. This open source system aims to help conservationists protect the last 2,000 lions living in the wild in
Southern Kenya, and safeguard the Maasai herders' cattle, restoring Maasai land to a working ecosystem. Photo
