Cel-Fi GO4 (G41) represents the latest in 4G cellular repeater technology. Building on the success of the GO2 model, GO4 has a higher output power (+20 dBm), providing the largest coverage area of all GO models.
GO4 operates on more frequency bands and can be easily switched between Telstra, Optus and Vodafone-TPG (one carrier at a time) should you change service provider.
Cel-Fi GO4 is ideal for inbuilding cellular coverage applications for Telstra, Optus and Vodafone. The higher output power means more service antennas can be run from the one repeater, and by popular request, the unit now has an RJ45 Ethernet network interface for remote management.
Expanding on GO2’s dual-band functionality, GO4 supports carrier aggregation with 40 MHz of relay bandwidth.

• 700L / 850 / 900 / 1800 / 2100 / 2600 MHz (Note:700 band is not supported on Vodafone)
• 3G, 4G, VoLTE, NB-IoT, (5G Ready*)
• Carrier Switching using WAVE App between Telstra, Optus or Vodafone – one carrier at a time
• Up to 3000 m2 coverage area, Two band simultaneous relay
• Total System Relay Bandwidth – Up to 40 MHz

Note: GO4 has the future capability to boost 5G as the feature is there but not enabled as it has not been approved by the carriers. When it does become approved, users will be able to run an update through the app which will enable the 5G functionality on the GO4 device.
