    4G LTE Network Extender is rated 3.9 out of 5 by 33.
    Rated 5 out of 5 by from Best in Home Service in Remote Area After reading the other reviews, I was not certain this would meet my needs for extending my Verizon service in my home. It MORE than met my needs and expectations! We live in a rural area where in home signal strength never exceeds 2 bars and is often 0. We have a metal roof which I think contributes to the problem too. I ordered this device and now have 4-5 bars 4g LTE through our rather large home. I simply plugged it in and it was setup and ready for use in about 15 minutes. It uses both WiFi and the tower signal to amplify the signal throughout the house. My wife has an Iphone and I have a Nexus 6P phone. The Nexus 6P was not listed as a compatible device, but it connected right away with no additional settings changes. Our downloads and uploads of messages, pictures and files is just like 4G LTE service in a city. I am very pleased with this product and recommend it.

    Rated 5 out of 5 by from Excellent Coverage at my home is horrible. Everywhere else is fine, so to I bought this Extender. It has amplified my poor signal excellently since. I hated the price but I caved because all of the other cell phone networks are terrible around my home as well. I would definitely recommend this Extender if you need to improve your 4G coverage.

    Rated 5 out of 5 by from Order of magnitude better than 3G Network Extender! Terrain makes it impossible to get VZW 4G LTE service at my home. Intermittent 3G service sometimes, but generally not good enough to hold a call. I have struggled with the Verizon 3G Network Extender(s) since the first model (SCS-26UC4) and later multiple second generation (SCS-2U01) trying to get whole house coverage. More recently we purchased WiFi Calling capable iPhone SEs but even that did not work well because the phones still prioritized to the wimpy 3G cellular signal. Entering Airplane Mode then turning WiFi and Bluetooth back on helped, but that's a hassle and you have to remember to undo it when you leave home. Plus, our iPhones would spend much battery life searching for a "real" cellular signal. This week when I found that the new 4G LTE Network Extender was available, I thought I'd spring for yet another one to add to my collection. It couldn't possibly be worse and the reviews seemed promising. It arrived yesterday and as an initial test I set it up in my south facing office window, connected an Ethernet cable to my home network switch and powered it up. Initial GPS fix was acquired within 15 minutes and shortly thereafter In Service. Wow! I got excellent (4-5 bars) service all over my home. This morning I pulled my old 3G Network Extender from my network shelf in a closet on the second floor and replaced it with the new 4G LTE NE, connecting to the previously installed remote GPS antenna in the attic. GPS fix acquired and In Service in under 5 minutes this time. I get -80 dBm all over second floor, -89 dBm in my office (which is about the farthest point from the Network Extender, and -82 dBm on the first floor. Speedtest testing consistently shows download in excess of 65 Mbps, upload averages 10 Mbps (limited by my Xfinity HSI service), 45 ms ping times. As a bonus, I get good 4G LTE cellular coverage outside as well, up to my detached garage I made no adjustments whatsoever to my home network router (an 802.11ac AirPort Extreme) and the 4G LTE NE had no difficulty connecting to Verizon's servers. Very impressed.

    Rated 5 out of 5 by from Perfect Upgrade Seamless upgrade from Samsung 3G Network Extender to 4G LTE. Easy setup: unplug old unit and plug in new - your ready to go! 4G LTE self setup took approximately 40 minutes to connect to the Verizon Network. We had full coverage throughout our home and was finally able to enjoy HD calling on both iPhone 7 and Samsung Galaxy 7 Edge devises.

    Rated 5 out of 5 by from So relieved! This was a lot of money to spend but since moving to the country a month ago none of our calls were going through. After much research I bit the bullett and bought. Within a half hour both husband and I had full bars. Set up was easy. This was money well spent!
