Overview

Most business internet providers in Australia are resellers. They sell you a connection that runs on someone else's network, which means when something goes wrong, they are waiting in the same queue as you. Summit Internet is different. We hold ACMA Carrier Licence #388, which means we build, own, operate and maintain the fixed wireless network your business connects to. When you call us with a question, you are speaking to the people who built the network.

Our fixed wireless service delivers business-grade internet via a small antenna installed on your rooftop, connecting directly to our transmission towers and fibre backbone. There is no copper, no cable in the ground, and no reliance on shared NBN infrastructure. The result is a dedicated, high-performance connection with symmetric speed options, low latency, and the kind of reliability that businesses running cloud applications, VoIP phone systems, and EFTPOS terminals actually need.

Whether you are a single-site office in Richmond or a multi-location retail chain spread across Melbourne's suburbs, our fixed wireless network gives you a genuine alternative to NBN, one that is faster to install, built exclusively for business, and backed by a team that has been doing this for over 26 years.

Key Benefits

  • Your Own Dedicated Connection

    Unlike standard NBN plans where your traffic shares bandwidth with dozens of other users (contention ratios can exceed 50:1), Summit's fixed wireless delivers dedicated bandwidth to your premises. Your speeds stay consistent whether it is 10am or 3pm on a busy weekday.

  • Symmetric Speeds Available

    Standard NBN plans are heavily asymmetric: uploads are a fraction of download speeds. The ACCC found that NBN fixed wireless upload speeds averaged just 11.2 Mbps during busy hours on popular plans. Summit offers symmetric speed options, giving your business the upload performance it needs for cloud backups, video conferencing, VoIP, and sending large files.

  • Connected in as Little as 10 Business Days

    Waiting weeks or months for a fibre build is not an option when your business needs to be online. Our installation team can have your fixed wireless connection live in as little as 10 business days from order. If we do not meet that timeframe, your first month is on us.

  • Built and Supported by the People Who Own It

    Because the network is ours, a fault is ours to fix rather than a ticket with a wholesaler. For businesses where every minute of downtime costs revenue (retailers losing EFTPOS transactions, pharmacies unable to dispense eScripts, legal firms missing court filing deadlines), our SLA provides genuine accountability.

  • No Underground Infrastructure Risk

    Fibre and copper cables buried underground are vulnerable to accidental cuts from construction, excavation work, and flooding. Our fixed wireless infrastructure operates above ground, which means a backhoe on the street outside your office will not take your internet down. When repairs are needed, they take hours rather than days.

  • Business-Only Network

    There are no residential customers on our network. Every design decision, every capacity upgrade, and every support process is built around the needs of business users. Your traffic is never competing with someone streaming video at home.

  • DDoS Protection Included

    Distributed denial-of-service attacks can cripple a business. Our network includes DDoS protection as standard, keeping your connection secure from volumetric attacks without the need for expensive third-party security services.

  • Support That Can Actually Fix It

    When you call 1300 049 749, you reach our own support team, people who know our network, understand business connectivity, and can resolve issues without reading from a script. No being transferred between departments, and no waiting on hold for hours.

Coverage

Summit's fixed wireless network covers 500+ suburbs across more than 4,500 square kilometres of Melbourne and regional Victoria. From the CBD to the outer suburbs, our network reaches businesses that other providers simply cannot serve with dedicated infrastructure.

Our coverage spans inner Melbourne, through the eastern, south-eastern, northern, and western corridors, and into regional Victoria. Whether your business is in a modern office park, a heritage shopfront, or an industrial estate, there is a strong chance we can connect you.

Not sure if you are in our coverage area? Enter your address on our coverage checker or call our team on 1300 049 749 for a quick assessment. If we cannot reach your premises with fixed wireless, we will recommend the best alternative from our range of business internet services.

How It Works

  1. 1 Coverage Check

    Enter your business address into our coverage tool or call our team. We will confirm whether your premises has line-of-sight to one of our transmission towers.

  2. 2 Site Survey

    If needed, our technicians will visit your premises to confirm the optimal antenna placement and signal quality. This is a quick, no-obligation process.

  3. 3 Installation

    Our installation team mounts a small, unobtrusive antenna on your rooftop and runs cabling to your network equipment inside. The antenna connects wirelessly to our nearest transmission tower, which links via fibre backhaul to our core network and data centre Points of Presence at NEXTDC facilities.

  4. 4 Go Live

    Your connection is configured, tested, and handed over, typically within 10 business days of your order. You are online and running on your own dedicated business link.

The Technology Behind It

Our network uses a combination of sub-6 GHz frequencies for last-mile access (the link between your antenna and our tower) and 11-80 GHz licensed microwave spectrum for high-capacity backhaul between towers and our fibre backbone. This architecture delivers:

  • Low latency typically between 5-20 ms, comparable to fibre
  • High throughput with speeds ranging from 10 Mbps up to 10 Gbps
  • Weather resilience: at the frequencies we use, Melbourne's weather conditions have minimal impact on performance
  • Dedicated capacity for each business connection

Our towers connect via fibre to our Points of Presence in NEXTDC data centres (M1 Melbourne, B2 Brisbane, P1 Perth, S1 Sydney), providing direct peering with major cloud platforms, carriers, and internet exchanges.

Use Cases

  • Offices Running Cloud Applications

    If your team relies on cloud-based tools such as Microsoft 365, Google Workspace, Xero, MYOB, Salesforce, or industry-specific software, your internet connection is essentially your office infrastructure. Fixed wireless delivers the consistent speeds and low latency these platforms need to run smoothly, without the busy-hour congestion that plagues shared NBN connections.

  • Retail and Hospitality Venues

    EFTPOS terminals, cloud-based POS systems, and inventory management platforms all need reliable, always-on connectivity. When your internet goes down, your tills stop working. Our fixed wireless with optional 4G backup ensures your business keeps trading.

    Retail

  • Healthcare and Medical Practices

    Medicare claiming, telehealth consultations, digital imaging, and practice management software all depend on reliable internet. Fixed wireless with symmetric upload speeds handles the demands of modern healthcare, and our 4G backup option means you never miss a Medicare claim.

    Dentists & GPs

  • Multi-Site Businesses

    Retail chains, franchise networks, real estate agencies with branch offices, and professional services firms with multiple locations can connect every site to our network without waiting for individual fibre builds. Consistent performance and centralised management across all your locations.

    Lawyers & Accountants

  • Businesses in NBN Black Spots

    Not every commercial premises gets reliable NBN service. Industrial estates, older commercial buildings, and areas still on legacy copper infrastructure often suffer from poor speeds and frequent dropouts. Our fixed wireless bypasses NBN entirely, giving you a dedicated connection regardless of the state of the copper or cable in your street.

  • Businesses That Need to Be Online Fast

    Opening a new office? Relocating? Setting up a temporary site? Where fibre builds can take months, our fixed wireless can have you connected in as little as 10 business days. Time is money, and we do not waste yours.

    This is the fundamental difference. Summit Internet holds ACMA Carrier Licence #388. We are a licensed telecommunications carrier, not a reseller. We built this network, we maintain it, and when something needs attention, our technicians are on it directly. There is no intermediary, no wholesale provider to wait on, and no finger-pointing between companies. The buck stops with us.

    26 Years of Melbourne Business Focus

    We have been connecting Melbourne businesses since August 2000. That is over 26 years of building, expanding, and refining our network to serve the specific needs of businesses across this city. We understand Melbourne's commercial geography, we know which areas are underserved by other infrastructure, and we have the track record to prove our reliability.

    Fixed wireless is our flagship, but it is not all we do. Summit provides business internet, hosted PBX phone systems, SIP trunking, business mobile SIMs, 1300/1800 numbers, fax to email, and 4G backup, all from a single provider. When your internet and phone system come from the same company running on the same network, you get integrated quality of service, a single point of accountability, and one invoice instead of four.

    The NBN Alternative Melbourne Businesses Have Been Waiting For

    If you have experienced NBN congestion during business hours, waited weeks for an NBN connection, or been told your premises cannot get the speeds you need, our fixed wireless network exists precisely for you. Faster installation, dedicated bandwidth, symmetric speed options, and a business-only network. It is everything NBN should have been for business.

  • After working with another ISP for several months to deliver a critical internet service for a major international sporting event, we were ultimately advised that the required upgrade was unlikely to be completed prior to event week. This left us facing a significant risk to service delivery. After exhausting all other options (and a few sleepless nights) we came across Summit Internet. From the initial conversation, Allan immediately understood the severity of the situation and quickly engaged his technical delivery team. Michael “Radar” was on site within days to assess and finalise a solution. Despite challenging conditions, including large trees and other obstructions, he worked tirelessly to design and implement an alternative approach. Leveraging an adjacent building, a temporary NBN connection, and a wireless link into the comms room, the solution was delivered within 24 hours of the initial site visit. Not only was the outcome faster than expected, but it was also more cost effective and delivered higher speeds than originally promised by the previous ISP. Over the course of the event, the service handled terabytes of data and supported hundreds of concurrent users without a single speed or performance issue. I cannot thank Summit Internet, particularly Allan and Radar enough for their exceptional service, technical expertise, and commitment to delivering under pressure. Highly recommended.Read more

Frequently asked questions

What is fixed wireless internet?
Fixed wireless internet uses radio signals to deliver a broadband connection between a small antenna on your rooftop and a nearby transmission tower. Unlike mobile broadband, both endpoints are fixed in place, which allows for much higher speeds, lower latency, and more consistent performance. Think of it as a dedicated, invisible cable between your business and our network, just without the cable.
How fast is Summit's fixed wireless?
Our fixed wireless speeds range from 10 Mbps to 10 Gbps, depending on your business requirements and location. We offer symmetric speed options, meaning your upload speeds can match your download speeds, something standard NBN plans do not provide.
Is fixed wireless affected by weather?
At the frequencies our network operates on (sub-6 GHz for access links), Melbourne's weather has minimal impact on performance. Our links are engineered with adequate signal margin to maintain connectivity even during heavy rain. Business-grade fixed wireless in 2026 is a very different technology from consumer-grade wireless. It is built to be resilient.
How does it compare to NBN?
Summit's fixed wireless offers several advantages over standard NBN for business: dedicated bandwidth rather than shared infrastructure, symmetric speed options, faster installation (10 business days vs weeks or months), no dependency on underground copper or cable, and direct support from the network owner. For businesses that need reliable, consistent performance, fixed wireless is typically the stronger choice.
What does installation involve?
Our technicians mount a small antenna on a suitable high point on your building (typically the roof) and run a cable to your internal network equipment. The process is quick, clean, and minimally disruptive. We handle all the technical setup and testing before handing the connection over to you.
Do I need line-of-sight to a tower?
Yes, fixed wireless requires a clear or near-clear line of sight between your antenna and our nearest transmission tower. Our coverage check and site survey process will confirm whether your premises can be connected. With towers across 500+ suburbs, most Melbourne business locations are within range.
Is there a lock-in contract?
We offer a range of contract options to suit your business. Contact our team on 1300 049 749 to discuss the terms that work best for your situation. We believe in earning your loyalty through service quality, not trapping you in a contract.
Can I keep my existing phone numbers?
Absolutely. If you bundle your fixed wireless with our hosted PBX or SIP trunking services, we can port your existing phone numbers across. You keep your numbers, and your callers will not notice any change, except perhaps that call quality has improved.
What happens if there is a fault?
Because we own the network, our own support team can diagnose and resolve issues directly. There is no waiting for a third-party wholesale provider to investigate. We monitor our network proactively, which means we often detect and address issues before you even notice them.
Can I add 4G backup to my fixed wireless connection?
Yes. We offer automatic 4G failover that kicks in seamlessly if your primary connection is interrupted. For businesses where downtime is not an option, such as retail, healthcare, and hospitality, this provides an essential safety net.
