MonitorMe transmits critical health data. Hence it needs a rock solid reliable communication method. At present the mobile phone is inadequate as conduit for vital health data. Lack of 3/4G signals, Wi-Fi or Broadband is not uncommon in remote & rural areas where Home Monitoring is most needed. Mobile batteries go flat, the ringer can be turned off or the handset left out of hearing. Such challenges prevent mobile devices being suitable as medical grade Vital Signs monitors.
Cordless phones offer reliable communications, but buttons are typically on the handset. Pressing buttons to answer questions not only disrupts the readings but reduces accuracy as patients must remove the device from their ear.
