- Signal Booster
A fix for a Verizon-only dead zone at home, not a general-purpose signal booster, and it depends entirely on having decent broadband already in place.

Overview
This is the Verizon Wireless 4G and 5G LTE Network Extender, model ASK-SFE116, a signal booster built only for the Verizon network. It works by tapping an existing home broadband connection to create a local cell signal indoors, rather than by amplifying an outside signal that is already weak.
A network extender is a different device from a passive signal amplifier: it uses your home internet as backhaul and broadcasts its own small Verizon cell inside the building, which is why it can restore service in a spot where there is no outside signal to amplify at all. That also means it is only as good as the broadband connection feeding it, and it does nothing for phones on other carriers. The listing shows a 3.1 average across 56 ratings, on the low side for this category.
- Verizon-branded 4G and 5G LTE network extender
- Model ASK-SFE116
- Creates a local signal using home broadband as backhaul
- Fixed indoor installation, not a portable booster
Who it's for
Verizon customers with a reliable home broadband line and a specific room or floor where calls drop or data crawls. It is not a fit for anyone on AT&T, T-Mobile, or another carrier, since the device only serves Verizon-connected phones.
Strengths and trade-offs
Drawn from this product's published specifications.
- Restores Verizon service where outside signal does not reach at all
- Covers both 4G LTE and 5G on the Verizon network
- Fixed installation suits a home office or a whole-house dead zone
- Useless without an existing broadband connection to plug into
- Only benefits phones on the Verizon network
- Average rating of 3.1 across 56 ratings is middling for the category
Performance notes
The extender pulls a data connection from your router and uses it to generate a small local LTE and 5G cell for Verizon devices nearby, which is why it can work in rooms with zero outside signal. Coverage is limited to roughly the area immediately around the unit, and call or data quality on it will only be as stable as the broadband line it rides on.

Questions about the Verizon signal boosters
Common buyer questions answered straight from the product spec data - no fluff, no "it depends".
Does the Verizon ASK-SFE116 work with other carriers?
No. It is built specifically for the Verizon Wireless network and only benefits phones on that carrier.
Do I need internet service for this to work?
Yes. A network extender like this one connects to your existing home broadband and uses it to generate a local cell signal, rather than amplifying an outside signal directly.
Will it work in a spot with zero Verizon bars today?
That is the scenario it is designed for, since it broadcasts its own signal from broadband rather than relying on outside coverage reaching the building.
