What’s LTE Band 31 450MHz Repeater?
LTE 450, also known as band 31, is a private LTE network applications using a 450MHz frequency.
Long-Term Evolution (LTE) telecommunications networks use several frequency bands,Band 31, FDD, 450, NMT, 452.5 – 457.5, 462.5 – 467.5 .
The most obvious difference in LTE 450 is its low frequency, at 450 MHz. Typical public networks have frequencies of 900, 1800, 2100 or 2600 MHz. The frequency of LTE 450, or band 31 as it is sometimes known, requires a dedicated LTE 450 module. This immediately gives LTE 450 an advantage in terms of less signal congestion.
LTE 450 itself is a wireless communication network based on a 450 MHz frequency. More importantly, it’s a network band that offers wide reach, deep signal penetration, high speeds and secure, dependable connection.
