This is a general guide to improving 4G and 5G data speeds at home. You may also be interested in our updated guide to the latest 5G signal boosters, which covers these in much greater detail.

There are 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 or 5G specification and allow for faster data rates. Newer hotspots often support the use of external antennas as well.

2. Use External Antennas [Best for Hotspots]

   Many hotspots from major carriers like AT&T, Verizon, Sprint and T-Mobile support external antenna ports. If you have a hotspot, check out our hotspot antenna guides and our 2x2 MIMO External Antenna kits or our 4x4 QuadPro and QuadMini antenna kits (depending on the number of cellular antenna ports available for your cellular router).

   We offer a 2x2 MIMO Panel and 2x2 MIMO Log Periodic antenna kit as well as a 4x4 Waveform QuadPro, and 4x4 Waveform QuadMini antenna kits. External antennas can improve both signal strength, signal quality, and help you access bands that aren't making it indoors. 

3. Use a MIMO Signal Booster [Best for Phones]

   Some hotspots and almost all phones don't have external antenna ports. For these types of devices, the best option for improving data rates is a MIMO signal booster/amplifier system.

   Cell phone signal boosters amplify your signal, increasing the signal strength (RSRP) while their directional outdoor antennas reduce interference, increasing the signal quality (SINR).

   We offer a Cel-Fi GO X MIMO Kit that achieves this goal. When using two boosters in a MIMO configuration in tandem with MIMO external antennas, they can allow for wireless rebroadcast of improved signal indoors.

Each of these options has a different set of effects on your 4G/5G signal, and thus your data rates:

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.

Check out our hotspot antenna guides and our 2x2 or 4x4 MIMO External Antenna kits for more information. We offer a 2x2 MIMO Panel and 2x2 MIMO Log Periodic antenna kit as well as a 4x4 Waveform QuadPro, and 4x4 Waveform QuadMini antenna kit.

We recommend using the Waveform QuadPro if you want to aim your antenna at your nearest cell towers for the fastest possible 5G data speeds, but if you'd prefer a more straightforward setup, the Waveform QuadMini will likely suit your needs better.

If your hotspot has four external cellular antenna ports, then it's usually best to go with a 4x4 antenna kit like the QuadPro or QuadMini. However, if it has only two then you’ll want the 2x2 MIMO Antenna Kit.

If the outdoor signal is very weak, but sufficient quality, 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/5G coverage indoors, use a MIMO cell signal booster.

A MIMO cell phone signal booster system amplifies the signal from outdoors, rebroadcasting indoors wirelessly to get you the best data rates.

We offer a Cel-Fi GO X MIMO Kit that is optimized for achieving a 2x2 MIMO connection in this format. When using the two boosters in a MIMO configuration in tandem with MIMO external antennas, they can allow for wireless rebroadcast of improved signal indoors.

There are five factors that affect the LTE/5G data speeds you experience.

Roughly by order of importance, these are:

1. Signal Quality (SINR)

   In 4G LTE and 5G 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 or 5G 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 and 5G 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/5G 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.
