3 Best Ways to Increase 4G LTE Data Speeds at Home

There are five factors that affect the LTE data speeds you experience.

Roughly by order of importance, these are:

1. Signal Quality (SINR)
   

   In 4G LTE networks, signal quality is measured as SINR. Increasing your SINR can have a dramatic impact on your connection speeds. The best way to improve SINR is to use a directional outdoor antenna, either connected to a signal booster or directly to an LTE hotspot.
   

2. Number of Connected Bands
   

   Your phone or hotspot can use multiple bands to connect simultaneously to the tower. This is called “Carrier Aggregation.” The more bands you’re connected on, the higher your data rates.

3. Signal Strength (RSRP)
   

   Many people think this is the most important factor, but it isn't. Signal strength, which is called RSRP in 4G LTE networks, definitely matters. But it’s often not the most important factor. If your RSRP signal is stronger than around -100 dBm, then a stronger signal won't help increase your data rates.

4. Tower Congestion
   

   The more users on the tower, the lower your data rates will be. In reality, tower congestion varies by band. Generally higher frequencies penetrate buildings less than lower frequencies. As a result, higher frequency bands are generally less congested. Using outdoor antennas connected directly to a hotspot or to a signal booster can help get you access to less-congested bands.

5. MIMO Support
   

   Both the tower and your LTE device use multiple antennas, in a configuration called “Multiple Input Multiple Output,” to increase data rates by around 30%. Most cell phone signal boosters are SISO – "Single Input Single Output" – though you can install two systems in parallel to get a MIMO booster.  

6. Throttling
   

   If you're on an "MVNO" like Tracfone, Straight Talk, or others, you're treated as a second-class citizen on the main carrier's network. Even if you're on AT&T, Verizon, T-Mobile or Sprint directly, you may be throttled if you use a lot of data each billing cycle. Throttling is a process by which carriers de-prioritize certain users or even cap their connection to a certain speed.

There are generally three things you can do to improve your data rates:

1. Get a New Phone/Hotspot
   

   If you're using an old device, a new phone or hotspot may allow you to connect to new bands. Newer devices support newer versions of the LTE specification that allow for faster data rates.

2. Use External Antennas
   

   Many hotspots from major carriers like AT&T, Verizon, Sprint and T-Mobile support external antenna ports. Phones don't have external antenna ports. If you are using a phone, you can use a signal booster with outdoor antennas to get a similar effect. External antennas can improve both signal strength, signal quality, and help you access bands that aren't making it indoors.

3. Use a Signal Booster
   

   Cell phone signal boosters amplify your signal, increasing the signal strength (RSRP). When used in tandem with external antennas, they can allow for wireless rebroadcast of improved signal indoors.

Here’s how each of these affects the five factors above:

If you want the very best data rates, and don’t mind relying on WiFi for distributing indoors, use the latest hotspot from your carrier with external antennas mounted outside the building or vehicle.

If the outdoor signal is very weak, you can add an inline “M2M” booster. We specifically recommend the Wilson Pro IoT 5-Band.

If you don’t have a hotspot, or can’t afford the monthly charges associated with adding a line of service, or if you simply want wireless LTE coverage indoors, use a cell signal booster.

A cell phone signal booster amplifies the signal from outdoors, rebroadcasting indoors wirelessly to get you the best data rates. Check out our in-depth review of the best cell signal boosters to find the right model for you.
