Jazz has deployed what it describes as Pakistan’s first and highest-capacity 15.1 Gbps microwave link operating over a single antenna, strengthening the infrastructure that carries mobile data between cellular sites and the wider telecom network.
The deployment uses a Super Dual Band configuration based on Huawei Technologies’ microwave platform.
Rather than requiring several separate antenna dishes to provide additional capacity, the system combines multiple carrier outdoor units on a single high-efficiency antenna.
The result is substantially higher data-carrying capacity while reducing the amount of physical equipment required on a telecom tower.
The development is particularly relevant as Pakistan’s mobile networks handle increasing data consumption and operators expand their recently launched 5G networks.
But the headline figure needs some explanation.
The 15.1 Gbps figure does not mean Jazz customers will receive 15.1 Gbps download speeds on their phones.
It refers to the capacity of a backhaul connection — one of the less visible but critically important parts of a mobile network.
What Has Jazz Actually Deployed?
Jazz says the new microwave connection can carry up to 15.1 gigabits per second over a single antenna configuration.
The system uses Huawei’s microwave technology and a Super Dual Band configuration.
According to the operator, it is Pakistan’s first and highest-capacity 15.1 Gbps microwave link operating over a single antenna.
The technology combines multiple carrier outdoor units rather than requiring separate antenna dishes for every additional link.
That allows Jazz to increase transmission capacity while using less tower space.

The deployment forms part of Jazz’s broader transport-network expansion across both microwave and fibre infrastructure.
What Is Mobile Backhaul?
When a smartphone connects to a nearby cellular tower, the tower is only the first stage of the connection.
Data must then travel from that mobile site into the operator’s wider network and eventually toward internet services, data centres and other networks.
The infrastructure carrying that traffic is known as backhaul.
A simplified mobile connection looks like this:
Smartphone → Mobile tower → Backhaul → Core network → Internet/service
Backhaul can be provided through several technologies.
Two particularly important ones are:
Fibre-optic connections
and
Microwave radio links.
Jazz uses both technologies within its transport network.
Why Does Backhaul Capacity Matter?
Imagine a mobile tower capable of providing extremely fast 5G connections to hundreds or thousands of devices.
The radio network may theoretically support enormous speeds.
But all of the data generated by those customers still needs to leave the mobile site.
If the backhaul connection cannot handle enough traffic, it can become a bottleneck.
This is why upgrading only the antennas that communicate with smartphones is not sufficient when building a high-performance mobile network.
Operators also need to upgrade:
- Backhaul
- Core networks
- Fibre networks
- Microwave links
- Data centres
- Routing equipment
- International connectivity
A modern 5G network therefore depends on much more infrastructure than the 5G antenna visible on a tower.
15.1 Gbps Does Not Mean 15.1 Gbps Mobile Internet
The distinction is important for consumers.
Jazz’s announcement refers to the aggregate capacity of the microwave backhaul link.
It does not mean an individual customer will be able to run a speed test and receive a 15.1 Gbps result.
A mobile site’s available capacity is shared among many users and network services.
Actual smartphone speeds depend on factors including:
- Available spectrum
- Signal strength
- Distance from the tower
- Number of connected users
- Network congestion
- Smartphone capabilities
- Radio configuration
- Backhaul capacity
- Core-network performance
- Internet-server capacity
Backhaul is therefore one part of the overall performance equation.
Increasing it helps prevent the transport network from becoming a bottleneck as mobile traffic grows.
Why Use Microwave Instead of Fibre?
Fibre is generally considered the preferred technology for extremely high-capacity fixed connections.
However, deploying fibre to every mobile site is not always practical.
Installing fibre can require:
- Trenching
- Road excavation
- Right-of-way approvals
- Civil construction
- Significant deployment time
- Higher installation costs in difficult locations
Microwave links transmit data wirelessly between two fixed points.
That can make them particularly valuable where fibre deployment is difficult, expensive or slow.
They can also provide network redundancy.
An operator therefore does not necessarily have to choose exclusively between fibre and microwave.
Modern mobile networks can use both.
How Microwave Backhaul Works
Unlike a normal cellular antenna serving smartphones across a wide area, microwave backhaul usually establishes a highly directional point-to-point connection.
Two network locations communicate with each other through carefully aligned antennas.
Data is transmitted using high-frequency radio signals.
Because the signal is highly directional, large amounts of data can be transported efficiently between sites.
The connection generally requires suitable line-of-sight conditions between the two endpoints.
Advances in modulation, spectrum utilisation, antenna design and multi-band technologies have allowed modern microwave systems to achieve capacities that would once have required fibre connections.
What Is Super Dual Band?
The Jazz deployment uses what is described as a Super Dual Band configuration.
The basic idea is to combine different frequency resources to increase overall capacity while maintaining a practical transmission distance.
Different microwave frequency bands have different characteristics.
Lower-frequency microwave links can generally provide better range and availability.
Higher-frequency bands can offer considerably more bandwidth.
Combining them allows an operator to use their complementary strengths.
This can provide much greater aggregate throughput than relying on a conventional single-band configuration.
Why a Single Antenna Matters
The 15.1 Gbps headline is only part of the technical achievement.
Jazz specifically emphasises that the capacity is being delivered through a single high-efficiency antenna.
Traditional expansion could require operators to install additional dishes and supporting equipment.
Tower space is limited.
Every additional antenna also creates considerations involving:
- Weight
- Wind loading
- Mounting structures
- Cabling
- Power
- Maintenance
- Installation complexity
Combining multiple carrier outdoor units with one antenna can therefore increase capacity without multiplying the number of large dishes mounted on the tower.
Useful for Crowded Urban Telecom Sites
The smaller physical footprint could be particularly useful in dense Pakistani cities.
Telecom towers and rooftop sites in areas such as Karachi, Lahore, Islamabad and Rawalpindi can face significant space constraints.
Operators may need to support equipment for multiple:
- Frequency bands
- 4G layers
- 5G layers
- Microwave links
- Power systems
- Transmission systems
Reducing the amount of hardware required for backhaul can make network expansion easier at these locations.
Why Jazz Needs More Backhaul Capacity
Pakistan’s mobile-data consumption continues to increase as consumers use smartphones for more bandwidth-intensive services.
Typical mobile traffic now includes:
- YouTube and other video streaming
- TikTok and short-form video
- Video calls
- Cloud storage
- Mobile gaming
- Social media
- Digital payments
- Remote work
- AI applications
- High-resolution content
5G can further increase the amount of data moving through each mobile site because users can consume information significantly faster.
If radio capacity increases without corresponding upgrades to the transport network, network performance can eventually become constrained by backhaul.
Jazz Launched 5G in Pakistan in March 2026
The microwave deployment also comes shortly after Pakistan entered its commercial 5G era.
Jazz officially launched its 5G services in March 2026 following the award of its Next Generation Mobile Services licence by the Pakistan Telecommunication Authority.
During the first phase, Jazz said 5G was active across approximately 180 sites.
Initial deployment covered major locations including:
- Islamabad
- Rawalpindi
- Lahore
- Karachi
- Peshawar
- Quetta
- Multan
- Faisalabad
Jazz secured spectrum across the 700 MHz, 2300 MHz, 2600 MHz and 3500 MHz bands during Pakistan’s spectrum process.
Different frequency bands allow operators to balance coverage and network capacity.
Why 5G Places More Pressure on Backhaul
A 4G tower serving relatively modest amounts of traffic may operate adequately with existing transmission capacity.
5G changes that calculation.
The radio interface can handle considerably more data, particularly when using wider spectrum channels.
Suppose hundreds of customers connected to the same site simultaneously begin:
- Streaming 4K video
- Downloading large files
- Uploading cloud backups
- Using video conferencing
- Playing online games
- Running AI applications
The aggregate traffic can become very large.
A high-capacity backhaul link allows more of that traffic to move between the tower and the wider network without encountering a transport bottleneck.
Jazz Is Also Expanding Fibre Capacity
Microwave is not the company’s only transport-network investment.
Earlier in 2026, Jazz announced another major upgrade involving its optical network.
The operator said it had deployed Pakistan’s first 1.2 Tbps per-wavelength capacity on its optical transport network in collaboration with Huawei.
Jazz also announced deployment of 100 Gbps Fiber-to-the-Site (FTTS) ring technology.
Those figures are much larger than the new 15.1 Gbps microwave link because fibre and microwave serve somewhat different network requirements.
The technologies should therefore not be compared simply by asking which has the higher headline speed.
Fibre and Microwave Have Different Strengths
A simplified comparison helps explain why operators continue investing in both technologies.
| Feature | Fibre Backhaul | Microwave Backhaul |
|---|---|---|
| Maximum capacity | Extremely high | Increasingly high |
| Physical cable required | Yes | No between endpoints |
| Deployment speed | Can require civil work | Often faster |
| Line of sight | Not required | Usually required |
| Difficult terrain | Can be expensive | Often advantageous |
| Dense urban deployment | Excellent where fibre exists | Useful where fibre access is difficult |
| Redundancy | Yes | Yes |
| 4G/5G suitability | Excellent | Excellent when properly engineered |
Large telecom networks typically use the appropriate technology depending on the location and capacity requirement.
Microwave Remains Relevant in the 5G Era
The arrival of 5G does not automatically mean every tower must immediately receive fibre.
Modern microwave technology can provide multi-gigabit capacities capable of supporting substantial mobile traffic.
That makes microwave particularly important in countries where universal fibre connectivity to every cellular site would require significant time and investment.
The technology can also provide backup connectivity where fibre already exists.
If a fibre route is damaged, a separate microwave path can improve network resilience.
Network Resilience Matters Too
Capacity attracts the most attention, but reliability is equally important.
Telecom networks can experience outages because of:
- Fibre cuts
- Construction accidents
- Power failures
- Flooding
- Equipment faults
- Severe weather
- Infrastructure damage
Having multiple transport technologies can provide operators with additional options for maintaining connectivity.
A combination of fibre and microwave can therefore improve both capacity and resilience when the network is designed with suitable redundancy.
Will Customers Immediately Get Faster Internet?
Not necessarily.
Installing a high-capacity microwave link does not automatically increase the speed of every Jazz connection across Pakistan.
The deployment applies to particular parts of the operator’s transport infrastructure.
However, expanding backhaul capacity can improve the network’s ability to support:
- More simultaneous users
- Higher peak traffic
- Additional 4G capacity
- Expanding 5G sites
- Lower congestion
- Higher data consumption
- Future network upgrades
Customers connected through sites benefiting from improved transport capacity could ultimately experience better performance, particularly where backhaul had previously become a constraint.
Why This Upgrade Matters More Than the Headline Speed
The most important aspect of the announcement is not simply that Jazz reached 15.1 Gbps.
It shows how Pakistan’s telecom infrastructure is changing beneath the consumer-facing network.
Consumers normally see:
4G
or
5G
on their smartphone screens.
Behind those icons is a much larger network involving fibre, microwave, routers, data centres, core networks and international connectivity.
As radio networks become faster, all of those supporting layers need to scale as well.
Pakistan’s 5G Expansion Will Require Continuous Infrastructure Investment
Pakistan’s initial 5G rollout is only the beginning of a much longer infrastructure cycle.
As operators expand coverage and more consumers purchase compatible smartphones, data consumption is likely to rise.
Network operators will therefore need additional investment in:
- Radio equipment
- Spectrum
- Fibre
- Microwave backhaul
- Power systems
- Core networks
- Edge infrastructure
- Data centres
Backhaul upgrades such as Jazz’s 15.1 Gbps microwave deployment form one part of that larger transition.
What Happens Next?
The significance of the new link will ultimately depend on how broadly similar technology is deployed.
A single high-capacity connection demonstrates what the technology can achieve.
The bigger consumer impact comes when higher-capacity backhaul becomes available across a larger number of network sites.
Jazz has not publicly detailed in this announcement how many additional sites will receive the same 15.1 Gbps configuration.
Future deployments will likely depend on traffic demand, available spectrum, site characteristics and the economics of fibre versus microwave at individual locations.
The Bottom Line
Jazz’s new 15.1 Gbps microwave link represents an important upgrade to the infrastructure behind Pakistan’s mobile networks.
Using Huawei’s microwave platform and a Super Dual Band configuration, the system combines multiple carrier outdoor units with a single high-efficiency antenna.
That allows significantly greater transmission capacity while reducing the number of separate antenna dishes and associated tower hardware.
For consumers, however, the 15.1 Gbps figure should not be confused with individual mobile internet speed.
It represents backhaul capacity — the high-speed connection carrying aggregated traffic from mobile sites into the wider Jazz network.
As Pakistan’s 5G network expands and mobile-data consumption grows, infrastructure such as this will become increasingly important.
Faster radios alone cannot deliver a high-quality 5G experience.
The network behind those radios needs enough capacity to carry the traffic — and that is exactly the problem high-capacity microwave and fibre backhaul are designed to solve.
