How Saudi Arabia is digitally transforming Hajj 2025 experience: Free WiFi, AI surveillance, and the world's largest cooling system
Every year, millions of Muslims from across the globe journey to the holy cities of Mecca and Medina to perform Hajj — one of the five pillars of Islam and the most significant spiritual undertaking in a Muslim's life.
This year, the Hajj pilgrimage is not only a religious journey of devotion and reflection but also a remarkable feat of digital transformation and technological innovation. For 2025,
Saudi Arabia
has introduced a host of cutting-edge upgrades to ensure pilgrims can perform their rituals with ease, safety, and seamless connectivity. From the provision of free, high-speed internet to the deployment of AI-powered crowd monitoring systems and climate-controlled mosque environments, the Kingdom is leveraging advanced technology to modernize the pilgrimage experience at an unprecedented scale.
This effort reflects the Kingdom's broader Vision 2030 goals, which include transforming Saudi Arabia into a global hub for innovation while preserving its deep-rooted religious and cultural heritage. According to the Gulf News report, with over 10,500 WiFi hotspots, full 4G and 5G coverage, AI-driven safety systems, and even the world's largest mosque cooling infrastructure, Hajj 2025 may be the most technologically advanced pilgrimage in Islamic history.

Hajj 2025 goes digital: Free internet across all holy sites
One of the most talked-about innovations this year is the provision of free, high-speed internet access for all Hajj pilgrims. Saudi Arabia has installed more than 10,500 WiFi access points throughout the pilgrimage zones, including Mecca, Medina, Mina, Arafat, and Muzdalifah. This vast network eliminates the need for pilgrims to seek connectivity during their rituals or logistical movements.
According to Saad Al Shanbari, spokesperson for the Hajj Communications and Technology System, the initiative aims to enhance both the spiritual and logistical journey of the pilgrims, as per the Gulf News report.
'There's no need to search for WiFi,' he stated. 'Internet access is now available for all pilgrims, everywhere.'
This connectivity not only allows pilgrims to stay in touch with family back home and access religious resources but also provides real-time updates, maps, and official communications directly from Hajj authorities.
Hajj 2025 now fully 5G-enabled across all holy sites
In tandem with the WiFi rollout, the Communications, Space and Technology Commission (CST) has achieved 100% 4G and 5G network coverage across all major Hajj sites. This includes high-density areas such as:
The Grand Mosque in Mecca
The Prophet's Mosque in Medina
Mina
Mount Arafat
Muzdalifah
This move ensures high bandwidth and low latency for millions of simultaneous users, accommodating massive data transfers, real-time video calls, and even live religious broadcasts to families and followers around the world.
Saudi authorities report that over 4,000 telecom engineers and technical staff have been deployed to maintain and optimize service during peak Hajj days.
AI-powered crowd management and surveillance
Crowd management during Hajj is critical, given that millions of pilgrims converge in confined spaces, especially during peak rituals like the Day of Arafat or the symbolic stoning at Jamarat. For 2025, Saudi Arabia has introduced an AI-powered crowd control and safety monitoring system developed in collaboration with Aramco Digital.
This system integrates:
Smart surveillance cameras
AI-based movement analytics
Specialized, secure communication networks
The AI monitors crowd flow in real time, identifies bottlenecks or high-density zones, and alerts authorities instantly to deploy crowd control personnel or reroute groups to avoid stampedes or accidents.
Al Shanbari emphasized the real-time responsiveness of the system, saying, 'We've deployed smart surveillance systems to manage crowd flows through AI-based monitoring and secure communications.
The safety of pilgrims is our highest priority.'
World's largest mosque cooling system
Another groundbreaking innovation is the world's largest cooling system installed at the Grand Mosque in Mecca. As Hajj 2025 coincides with the peak of summer in Saudi Arabia, temperatures are expected to soar above 45°C (113°F). To combat this, the Kingdom has enhanced its centralized air conditioning infrastructure, using underground pipelines to pump chilled air across prayer halls and corridors.
The cooling system comprises:
Massive chiller plants located away from the mosque
Pipelines transporting cooled water to air handlers within the mosque
Advanced filtration systems to ensure clean, dust-free air
This is a critical move for public health and comfort, especially for elderly and physically vulnerable pilgrims. Saudi Arabia's Ministry of Hajj and Umrah confirmed that this upgrade has already helped prevent numerous cases of heatstroke and dehydration during the initial phases of Hajj 2025.
AI-assisted medical support and emergency response
As part of the smart Hajj initiative, Saudi Arabia has also digitized its emergency response operations.
Hospitals and medical tents near pilgrimage sites are now AI-integrated and GPS-synced, enabling faster triaging, emergency routing, and real-time coordination between ambulances and medical teams.
An example of the system's success emerged recently when an Egyptian pilgrim survived a heart attack and received immediate treatment thanks to the system's real-time alert and GPS tracking. He is now recovering and is expected to resume his pilgrimage after medical clearance.
Smart Hajj app
: A digital guide in your pocket
To tie everything together, Saudi Arabia has launched the Hajj Smart App, an all-in-one platform offering:
Multilingual navigation tools
Live updates on rituals and crowd status
Emergency assistance contact
Health and prayer reminders
Maps and transit schedules
This app is GPS-enabled and linked to the broader smart infrastructure, allowing pilgrims to navigate easily, even in dense crowds or unfamiliar areas.
