Kazakhstan, the ninth-largest country in the world, boasts vast landscapes, sparse population distribution, and regions of immense economic potential. Yet, these very features present unique challenges to nationwide connectivity. In a digital-first era, cellular backhaul solutions, especially via satellite have emerged as a game-changing enabler of transformation across sectors.
Why Cellular Backhaul Is Essential for Kazakhstan
Geographically, Kazakhstan is expansive, with a population density of just 7.65 people/km² despite a total population of 20 million. Approximately 1,200 villages still lack mobile broadband, and around 630 hard-to-reach villages remain without any cellular signal. This digital exclusion hampers growth, service access, and innovation.
Cellular backhaul, which connects remote mobile base stations to the core network, becomes crucial here. Without the need to lay fibre-optic cables across challenging terrain, satellite-enabled backhaul provides an agile, scalable, and cost-effective alternative, essential for connecting dispersed populations and supporting nationwide digitalisation efforts.
Understanding Cellular Backhaul
Cellular backhaul refers to the communication link between a mobile network’s core and its edge (base stations or towers). It carries user data, signaling, and control traffic back to central servers, enabling seamless internet and voice services.
Traditionally powered via fibre or microwave links, cellular backhaul in rugged terrains like Kazakhstan’s is better served through satellite connectivity, especially LEO (Low Earth Orbit) networks like Starlink. This removes dependency on ground infrastructure, making it ideal for scaling coverage across remote regions.
Why the Connectivity Gap Exists
Kazakhstan’s current mobile network coverage is concentrated in urban centers. Although 92% of the population uses the internet, this statistic masks a deep urban-rural divide. The challenge stems from:
- Sparse settlements across regions like Ulytau and Mangystau
- Harsh climates and rugged terrain, making fibre deployment cost-prohibitive
- Low ROI for MNOs in investing in traditional infrastructure for remote areas
To address this, cellular operators require a backhaul solution that’s flexible, fast to deploy, and economically sustainable.
Cellular Backhaul via Starlink: A Scalable Solution for GSM Operators
Starlink’s Low Earth Orbit (LEO) satellite constellation offers a high-bandwidth, low-latency alternative to traditional satellite systems—making it an ideal solution for GSM operators looking to expand network coverage into underserved regions.
Starlink was officially launched in Kazakhstan on 13th August, unlocking new opportunities for the regional telecom operators.
With Starlink, GSM service providers can:
- Expand coverage without the cost of terrestrial infrastructure, eliminating the need for fibre or microwave links in remote areas.
- Ensure high service quality, inherent to the Starlink network, thanks to its low latency, high bandwidth, ideal for supporting 4G and 5G rollouts even in hard-to-reach locations.
Globally, Starlink has proven its impact: in rural Nigeria, it enabled a 45% increase in network traffic across more than 100 base stations.
Key Features of Starlink for GSM Operators:
- Inter-Satellite Laser Links for Reliable Routing
Starlink’s satellite constellation is equipped with advanced inter-satellite laser links, allowing data to be routed through space without relying on ground station. For GSM operators, this means more resilient and uninterrupted mobile service in both rural and high-demand environments.
- Low Latency Comparable to Fibre
With latency as low as 20–40 ms, Starlink’s performance rivals traditional terrestrial networks, essential for seamless voice calls, real-time applications, and 5G services.
- High Bandwidth for Data-Intensive Services
Starlink supports high-throughput backhaul, making it suitable for dense traffic zones or base stations serving high user volumes, especially useful during peak hours or seasonal spikes.
- Quick and Scalable Deployment
Starlink terminals can be installed in hours, not weeks, allowing GSM operators to rapidly expand coverage or restore service after outages or disasters without long lead times.
- Cost Efficiency
Starlink backhaul is up to 7x more affordable than traditional satellite options (according to Analysys Mason), reducing the Total Cost of Ownership (TCO) for rural expansion projects.
