With the rise of geofencing technology, it’s now possible for companies to track the location of cell phones with great accuracy. Geofencing has many applications, including marketing and security. In this blog post, we will discuss how geofencing for marketers works and how it can be used to track cell phones.

How Marketers are using Geofencing

Geofencing is a technology that uses WIFI, GPS (Global Positioning System), or RFID (Radio Frequency Identification) to create a virtual boundary around a physical location. When a person enters a geofenced area, marketers can track the smartphones This allows companies to target ads and marketing messages to people who are in the vicinity of their store or office. It also allows them to track the movements of employees and customers.

Location-Based Marketing Information is Derived from Several Sources:

  • From the IP address of your Internet connection
  • From the GPS signal of your mobile phone
  • From the location of nearby cell towers
  • From the location of Wi-Fi hotspots

The geofencing system then uses this information to calculate your location. This process is called trilateration.

Currently, most tracking apps for cell phones work by accessing GPS. This provides users with feedback on an app or software. To understand how tracking works for mobile phones, it is necessary to examine each major model and the options available for tracking the desired device.

The most accurate source of location information is the GPS signal from the phone itself. If a phone does not have a GPS chip, geofencing providers can use cell tower triangulation or Wi-Fi networks to approximate the location of the phone.

IP Addresses

An IP address (also called Internet address) is assigned to your device by your Internet Service Provider (ISP) and is required to access the internet. IP addresses make the connection between your devices, websites, and the services you use. When you geofence someone, you’re using their IP address to pinpoint their location.

GPS Signals

GPS signals are used by geofencing systems to track the location of a mobile phone. GPS stands for Global Positioning System and is a satellite-based navigation system.It can precisely determine the location of a person or object on the earth’s surface. A network of satellites transmits GPS signals which are then received by GPS-enabled devices, such as smartphones.

Cell Towers

Marketers use cell towers to geofence people who do not have GPS-enabled devices. Cell towers are structures that house radio equipment used for communications between cell phones and base stations. Generally, mobile phone service providers own cell towers. These are located in areas with a high density of cell phone users.

Wi-Fi Hotspots

Wi-Fi hotspots are a useful tool in geofencing for marketers. Itis used to geofence people. Wi-Fi hotspots are locations where Wi-Fi networks are available for public use. Therefore, when you geofence someone using a Wi-Fi hotspot, you’re using the location of the Wi-Fi hotspot to pinpoint their location.

Bluetooth Beacons

Bluetooth beacons are another way to geofence people. Bluetooth beacons are small, battery-powered devices that use Bluetooth technology to transmit signals. When a Bluetooth beacon is within range of a compatible device, it can send a signal to geofence the device.


Cell-ID is a technology that uses the signal strength of nearby cell towers for geofencing. In areas where GPS signals are weak or unavailable, you can use Cell-ID for geofencing. It can be used to geofence people who are indoors or in rural areas.

Wi-Fi Networks

Wi-Fi networks are helpful when you want to create a geofence around a certain area. Using a Wi-Fi network for geofencing people allows you to pinpoint their location. Wi-Fi networks are typically used in urban areas where there is a high density of Wi-Fi networks.

Geofencing Platforms use Trilateration

Geofencing platforms use trilateration to calculate the location of a person or object. Trilateration is a process of determining the position of an object using the distances to three other objects. In geofencing, trilateration is used to calculate the location of a mobile phone by using the distance to three nearby cell towers.

Why Marketers Should Use Geofencing?

Geofencing for Marketers

Geofencing is a powerful marketing tool that enables marketers to reach potential customers. Geofencing for marketers allows you to build customer loyalty from a pool of audiences physically attending specific locations. For example, it helps to target people who are near a competitor’s location, store, or event. Geofencing can also be used to target people who are in a certain age group or income group.

Moreover, geofencing is a cost-effective way to reach potential customers. It is a targeted form of marketing that can reach people who are interested in your product or service. Due to its flexibility, you can deliver a message to potential customers in a variety of different ways.

In addition to this, geofencing technology is versatile enough to be used in many different industries. It can be used to target people who are interested in cars, real estate, or even food. Along with this, geofencing can target people who are in a specific location, such as a city or state.

Some Drawbacks of This Application

In recent history, the location of a cell phone was only traceable using triangulation techniques available to law enforcement and other government agencies.  This is before people began to incorporate GPS into the majority of mobile devices sold on the market. Geofencing takes advantage of the GPS capabilities of these devices to provide a more accurate tracking solution.

Geofencing is Cutting Edge Marketing Technology

Geofencing technology is still in its early stages, but it has great potential for marketers. Geofencing for marketers allows you to target ads to people who are in a specific location. For example, geofencing can be used to target people who are near a store or landmark.

Geofencing is a powerful tool for marketers, but it is important to use geofencing responsibly. It has many benefits for businesses and organizations.
