Assignee: GLOBAL MARKET DEVELOPMENT INC.
Field: Telecommunications (Electrical engineering)
Classification: CPC H  G | IPC H

Claim 0:
1. An integrated telecommunications handset/field phone comprising:
a microphone, earphone, a volume control wheel, headset jack, first and second push to talk (PTT) buttons for connection to a first radio net channel, and said second PTT button for connection to a second radio net channel;
a programmable microcontroller;
a user manipulatable touchscreen; and
an integrated electronics system including a DTMF encoder/decoder;
wherein said integrated electronics system cooperates with said programmable microcontroller, keypad and said DTMF encoder/decoder, enabling Bluetooth communications directly between handsets that are authenticated as part of a group of handsets, such authentication being effected by a display on said touchscreen that highlights a list of authenticated group members that are enabled to communicate with each other using a subset of the members of a group in a conference call, and provide screenshots to users that request information including defining the extent of the Bluetooth range of a group of authenticated handsets, which handsets in a group of authenticated handsets have permissions to communicate directly to each handset member of the group of handsets as determined by software in said programmable microcontroller; and
said programmable microcontroller knowing when a radio channel is inoperational will switch to an operational radio channel.
