IP Transceiver


Instant Wide Area Coverage Over an LTE (4G) and 3G Network

Communication throughout the Coverage of LTE (4G) and 3G Network

Using an existing LTE (4G) and 3G network, the IP503H is able to provide a network with wide area coverage capabilities. The IP503H does not require its own repeaters or IP network which reduces the cost of building and maintaining a wide area radio network.

* Service availability depends on the country. Network coverage provided by custom ICOM SIM card.

Simultaneous TalkListen Function for Full-Duplex Communication

The Simultaneous TalkListen function provides full-duplex one-to-many communication which users can talk and receive at the same time like a telephone style conversation.

Multiple User Communication

Multiple users in the call groups can initiate calls instantaneously. Removing the need to wait for available channels to communicate.

Priority Interrupt Calling

The IP503H supports group calls with three or more people. In case of an emergency, you can break into an on-going call to transmit an important message.

Industry Leading Compact and Lightweight Body

Compact 59 × 95 × 32 mm; 2.3 × 3.7 × 1.3 in and 240 g; 8.5 oz (approximate) lightweight body* allows non-intrusive mobility and use.

* With BP-272 battery pack and antenna. Projections are not included.

IP67 Dust-Tight and Waterproof

The IP503H has been designed to preserve its waterproof integrity in water of a depth of 1 meter for 30 minutes. It can be used for outdoor work or places prone to get wet.

Optional Charger Cradle With Bluetooth® Function

When the optional BC-218, charger cradle and HM-215, speaker-microphone is used, calls can be made with the microphone, while charging the IP503H. Even when the IP503H is not dropped into the BC-218, the Bluetooth® function enables you to wirelessly use the speaker-microphone.

* May not be available in some countries. Please confirm the regulations in your country before you use.
