Late this week, the FCC approved some changes to the current allotment of the wireless spectrum, paving the way for Sprint to expand its current 3G network and launch an LTE service. The FCC also approved a second set of spectrum-use rules, regulating the 2360-2400 MHz band for use in hospitals as a "Medical Body Area Network," or MBAN. The MBAN will allow doctors to hook their patients up to the physiological sensors like EEGs, heart monitors or neo-natal sensors and have those lightweight and often disposable sensors transmit information back to the monitoring equipment without wires.
