What is AWIN? • The statewide, multiple site, digital 700/800 MHz trunked communications system using the Association of Public Safety Communications Officials (APCO) Project 25 (P 25) standard. • AWIN provides a reliable, statewide means of communication for the state’s first responders. The AWIN system consists of over 100 tower sites and over 27, 000 authorized radios. • AWIN provides statewide operations, • AWIN is monitored 24/7/365 to within the coverage area of the system ensure that it is available whenever for public service entities using P 25 the first responder needs it. digital 700/800 MHz radios.

Trunking Radio Systems – Basic Overview What is Trunking? • Trunking is defined as: “The sharing of a limited number of communication paths (or Trunks) among many users” • Trunking is not a term that is owned or belongs to a specific vendor/manufacturer. • Trunking is not a term that is exclusive to radio systems.

Trunking vs. Conventional Radio Systems • Conventional Radio (repeater) System: • Uses a dedicated radio frequency for each radio channel in a system (unless sharing a channel) • A Channel = a Frequency (i. e. , 155. 555 MHz is County Sheriff, 156. 555 is County Fire) • Each frequency is assigned to a group of users.

Trunking vs. Conventional Radio Systems • Conventional Radio (base or repeater) System: • A Channel = A Frequency • If a channel is in use, the radio user must wait in “queue” before being able to transmit on the system. • A new frequency must be obtained each time another “channel” is needed in the radio system. • The system is limited by the number of frequencies in the system.

Trunking vs. Conventional Radio Systems • Trunked Radio (repeater) System: • Uses a group of similar radio frequencies to create a “pool” for radio system user to access. • Systems can by built using VHF, UHF, 700, or 800 MHz. (AWIN is 700/800) • A Channel is NOT a Frequency (generally speaking) • A Channel (on your radio) is now a computer generated code… • …referred to as a TALK GROUP

Trunking vs. Conventional Radio Systems • Trunked Radio (repeater) System: • The entire system is managed by a computer, on AWIN this is called the Zone Controller. One Zone Controller for the North ½ of the State and one Zone Controller for the South ½ of the State. • All radio in the system, also, are computer controlled, and communicate to the Zone Controller via one frequency know as the “Control Channel”.

Trunking vs. Conventional Radio Systems • Trunked Radio System Benefits: • Greatly improved usage of radio frequencies (can be quite scarce depending on frequency band) • Brings radio users together on a common radio system. • Consistency in radio coverage. • Greater over radio system flexibility, including: • Channel (Talk Group) capabilities. • Various user features, including Emergency Alarm, PTT ID, Channel Regrouping, Call Alert, and Radio Inhibit.

Trunking vs. Conventional Radio Systems • Talk Group Dragging ◦ Dragging is when a talk group is being used across the radio system and is not part of the incident/area they are listening in to. ◦ A trunked (AWIN) radio system can not tell when a radio is just listening – It assumes all affiliated radios are equally important and needs the recourses. ◦ This “just listening” will use up resources at each tower it crosses to get the message/PTT to you.
