A method of beginning a data exchange over a wireless communication channel between a destination device and a sending device comprising:

• waiting, by the sending device, a period of time that is at least as long as a predetermined time period and detecting no communication on the wireless communication channel;
• attempting, by the sending device, to initiate communication to the destination device;
• and
• if the attempt to initiate communication to the destination device proves successful, transmitting, by the sending device, a series of packets wherein each two consecutive packet transmissions are separated by no more than the predetermined time period.

A method of beginning communication within a wireless communication network among a plurality of devices comprising:

• determining whether communication is being performed from a first device of the plurality of devices to a second device of the plurality of device, the communication being performed on a communication channel within the wireless communication network;
• initiating communication between the first device and the second device after determining that no communication is being performed;
• and
• continuing the communication when the communication proves successful.
