Band 66 frequency

Therefore, for any cell signal booster to help, outside signal strength must be at least -110dBm (3G) or -120dBm (4G) or there must be a clear line of sight to a cell tower that is within twenty miles of your home / building. Please check outside signal level in decibels before ordering.

Are Cell Phone Boosters Safe? Although some people believe that cell boosters are dangerous and emit greater levels of radiation compared to a traditional cell phone, the opposite is true. Cell signal boosters emit considerably less radiation than a cell phone, and they keep harmful radiation away from the user .

Band 66 is an LTE operating frequency Band . LTE is designed to work across a number of frequency bands – E-UTRA operating bands- currently ranging from 450 MHz up to 3.8GHz. The available bandwidths are also flexible starting with 1.4 MHz up to 20 MHz with Carrier Aggregation allowing use of wider multiples.

The gain of your cell phone signal booster kit comes primarily from two components: the amplifier (also called the booster) and the outdoor donor antenna. Most cell boosters are limited to between 64 dB and 72 dB gain by the FCC, however, single-carrier devices can amplify signal by up to 100 dB .

【SUPPORTS MOST CARRIERS】- The booster supports All U.S. Carriers 4G LTE for Verizon, AT&T, T-mobile, Straight Talk, MetroPCS, Mint Mobile, Cricket Wireless etc. Works with all cellular devices operating on band 4/66 . (1700/2100Mhz).
