Make Your Own Cell Phone Signal Booster for 2G-3G-4G Network

 Make Your Own Cell Phone Signal Booster for 2G-3G-4G Network

Before begin. Where i stay is a rural area., cell phone signal reception is a nightmare. 1 bar or no service, the best i can get is 2 bar. After a long search for a solution, trial and error. Discover this simple solution without purchasing an expensive 3G signal booster. Here the guide to build one from household items.

DIY 2G/3G/4G wireless cell phone signal booster is a home-brew booster which uses common household items. This DIY can improve the signal of cell phone signal inside your house, from 1 bar to full. You need to build 2 units, one indoor, one outdoor, both unit is similar and simple to build if you follow this guide, but i take few hours to R&D. I name it, LauC2 antenna. Before we start, safety first wear eye protector glass and safety gloves. When you see the bold text, it is special for people who want details instructions. This project can be built using materials you can find, finished LauC2 antenna have to 80% like the photo. Primary objective is E GSM 900, 2G signal reception. You need at least have cell phone signal coverage at outside your house for this antenna to function and working, 1 bar signal strength or come and go.

Use the phone as usual, not wired. No wire connected to your phone.

USE AT YOUR OWN RISK

First get all these items from your house:

iron wire from clothes stand / wire coat hanger, [double check using a magnet is iron], 2-4 mm iron wire. Or you can get iron wire without paint coating to improve efficiency.

two piece extend electric cable connector block, 20A [if any]

common cable TV cable / coaxial cable / satellite TV cable, 30 meter good quality coaxial cable, no cut and joined.

wire cutter

pliers

Screw driver, 3-6 mm phillips screw drive and slot screw driver.

You can find all these items at your nearby supermarket, hardware shop.

Look at the drawing. First section we are going to build is the 3G antenna using the iron wire from the clothes stand /wire coat hanger, the black color drawing. Not necessary to remove the paint coating.

Straiten the clothes stand wire / wire coat hanger with pliers [i using hand] and bend it 4cm at the corner about 45 degrees.

Then measure 8cm from the bend and bend forwards at 90 degrees.

Then measure 9cm from the bend and bend forwards at 90 degrees.

Then measure 9cm from the bend and bend forwards at 90 degrees.

Then measure 8cm from the bend and bend forwards at 90 degrees.

Last bending is the same as the first bland 4cm about 45 degrees where install extend electric cable connector block, insert the connector block to the ends of the both end of the wire and tighten it.

All wire is connected inside the connector block. The 4cm area, clean/remove the clothes stand / wire coat hanger shield [paint coating]. You have to use the wire cutter to cut the wire. Build 2 unit. One clothes stand enough for building 2 unit this type of antenna. Maybe take you 1-2 hours or less.

Next step is the wireless antenna, the orange and yellow drawing. This section we need to use the common cable TV cable. So first cut off the plastic jacket about 15-20 cm length, depending on the center core round / turns, if you are planning for testing the center core round / turns, maybe a good idea about 20 cm. depends on the center core round / turns diameter. Now you can see the [metallic shield] like a spider web, cut off this metallic shield and look at the drawing again, the red line is the metallic shield to be installed. No waste. Just twisted down the metallic shield to become a wire without cutting [cut it if too long] and fit into the connector block at the red line and tighten, not necessary a U shape. Then back to the cable, cut off the dielectric insulator carefully, we need the center core for building the wireless antenna.

Back to the drawing again. About 5cm from the edge of the center core [or start at plastic jacket edge depend on the length of center core], we need to make 5 round / turns clockwise, E GSM 900 2G, we can do it using screw driver [3- 6 mm phillips screw drive], just bend the center core round and round / turns on the rod. Then straighten the center core both area like the photo. Now we need to mount this wireless antenna to the 3G antenna. Look at the drawing how this is done. Remember the edge of the center core wire have to join the iron wire and tighten. Don't forget the red wire.

After some testing, B1-WCDMA 2100, 4G have to be center core 7 round / turns at outdoor unit, and center core 5 round / turns at indoor unit. Use your smartphone searching for the location have STRONG 4G signal to put the outdoor unit.

A good signal strength define is maybe a stable 3 bar 2G signal, not an unstable signal strength jump up and down too often. Probably take a while for getting the right place.

If you are not very sure, just make it 7 round /turns at out door unit and 5 round /turns at indoor unit. If the signal strength is still too weak, you can trial and error increase the outdoor unit the center round/turns 1 at a time. 1 round/turns mean 1 complete circle.

So you need both edge [cutting edge] of the cable to be the wireless antenna. Better install the cable one end at the roof top or near the roof top, open area. One end is inside the house, anywhere you like.

Completed assembly, both end of the TV cable have a finished LauC2 antenna like the photo.

When you finish building 2 unit of this antenna. One unit installed at outdoor where you can get STRONG cell signal strength and the front [flat area] of the antenna have to face vertical to cell tower, somewhere. Adjust the LauC2 antenna until you are satisfied with the signal strength, test using your phone, recommended phone set to 2G for antenna adjustment purpose. Stay away from any wire mesh, object blocking, wireless device. Can put inside house window where can get good signal strength. If your house has lighting strike history, keep the antenna in a secure location.

Now the indoor unit, anywhere you like where you want to put the antenna. Recommended at height area and open area for better indoor reception [or center of the hall ceiling], and the location you are always busy with your phone and keep distance with the wireless router. Just one condition, vertical or horizontal. Why? you asking? Take your phone, if the antenna is vertical, the phone also vertical getting strong signal strength. 2G signal always have better cell phone signal reception, tested device Nokia 1110i, 3 bar or full. Lumia 635 2G can get 3 bar signal. Moving too far away from the Lau2C indoor unit antenna, signal drop, tested 20-25m still have 2-3 bar. 1-3m i get full bar using Nokia 1110i. Smartphone always having poor signal strength.

Take off your smartphone additional phone case, some phone case really weakening the reception. If everything is right, you can dial out and receive income call, even the phone shows weak signal inside the house, all phone carriers do have a free call customer hotline, dial the number and listen to the audio quality.

The antenna no insulation part should not touch the wall or electrical conductor.

If you want some dB value, enter Field Test mode on your smartphone

Nokia / Windows Phone, dial ##3282#

iPhone, dial *3001#12345#*

Android, access Settings>General>About Phone> Network or Status

Closer the value to -50dB, better the signal strength

You can also cut a small piece of cooking aluminum foil, around the phone

side body thickness and length. Put it on the left or right side and hidden inside the phone case. To boost 2G signal. In this case I'm using a Nokia Lumia 635 Rubber Silicone case bought from eBay. You can see the photo, is Nokia 1110i, aluminum foil fit inside the transparent phone case.

Somehow you can also use your phone headphones work as an Antenna too, many people look over this.

Look at the photo above. I added additional wire. Something i am trying to do is increase the indoor unit smartphone reception. is additional, trial and error. You only need to cut 1 piece 30cm center wire, from the one edge about 5cm, 4 round / turns on the pencil body then pull a little bit on the wire. Then fit at one of the join, depends on your antenna. This does not increase the signal strength. Show promising result.

The version 2.0. Kind of science fiction, have 3 assembly in 1. This design show more promising result, but you still have to install it at the right location, where have a consistent stable cell signal strength for outdoor unit. Picture coming soon.

Assembly 1, step by step guide

straiten the iron wire coat hanger.

Bend it 4cm at the corner about 45 degrees, only this area has to remove the paint coating.

then measure 8cm from the bend and bend forwards at 90 degrees.

then measure 9cm from the bend and bend forwards at 90 degrees.

then measure 9cm from the bend and bend forwards at 90 degrees.

then measure 8cm from the bend and bend forwards at 90 degrees

Then from the bend rotate 90 degrees.

then measure 9cm from the bend and bend forwards at 90 degrees.

Then measure 10cm from the bend and bend inwards at 90 degrees.

Then measure 10cm from the bend and bend inwards at 90 degrees.

then measure 9cm from the bend.

Last bending is the same as the first bland 4cm about inwards 45 degrees, and remove the paint coating.

End to End 4cm iron wire fit into the connector block and tighten.

so is internal 3G antenna and external 3G antenna in 1.

Assembly 2, step by step guide

you can use the existing 3G antenna or follow the guide at Step 1.

the End to End 4cm area, just measure a sufficient length that can fit into the connector block, maybe a 1cm.

Bend both End 90 degrees forward.

Replace the red wire with this assembly, meaning this assembly is horizontal at the center of the assembly 1.

fit into the bottom of the connector block and tighten.

Assembly 3, step by step guide

the wireless antenna. Almost same like the old design.

7 turns for outdoor unit and 5 turns for indoor unit

The length have to reach the bottom of the assembly 1, you can pull a bit.

fit into the connector block and tighten.

Note: You can also bend this antenna just using one piece of iron wire without paint coating without any cutting too. And also can adjust all the antenna to different angle to improve efficiency.

This what i did to my Dlink 2750E ADSL N-300 Wireless router, as pictures show you. By this simple modification on the wireless router antenna, the antenna is attached on the router antenna. I am able to get more reliable internet through a solid concrete wall, example wireless signal broadcast to my room, in between have a solid concrete wall. You can try this.
