Description
Following the technological evolution of the Cel-Fi G41, the G51 is next in the series, providing all the brilliance of the G41 with the addition of mid-band 5G. G51 automatically scans and boosts the entire channel width of 5G 3500 MHz, which is the major global 5G band known as n78, along with boosting a 4G band to provide long range connectivity.
G51 is essential for any tech professional, enterprise, or industrial environment looking to leverage the low latency and ultra-fast data performance that 5G brings. Unlike complicated "Private 5G" networks or DAS which can take 6-12 months to implement, G51 can be installed in as little as a few hours. The unit identifies and locks on to the network operator's 5G network, and can be connected to one or many antennas distributed throughout the building to provide seamless, strong voice and data connectivity.
Cel-Fi G51 is a very straight forward device, it has a single input RF connector which connects to a roof-mounted (donor) antenna, and a single output RF connector which connects to an indoor (service) antenna. Powertec provide a range of 5G-compatible antennas that have been laboratory verified for best performance on n78 5G.
The output power of G51 is +20 dBm for most bands. It's important to be mindful that while the stated output power for n78 is +27 dBm, the larger 100 MHz channel width (up to 5x wider than 4G) means that more power is required to lift the channel to the same level of output power (per MHz) as its 4G channels, rather than being used to deliver a larger coverage footprint.
