Business broadband routers explained

Everyone knows that routers are essential, but few understand what they actually do.

In this article, we explain what routers are, why they are important and where they fit into a business broadband network.

Check out the shortcuts below if you already know what you’re searching for.


Broadband routers for businesses

Business broadband routers refer to top-tier routers designed for businesses and enterprises. They boast features like high-speed and bandwidth support, multiple Wi-Fi bands and WAN ports, and integrated VPN capabilities.

While these routers are tailored for the commercial sector, they are available to anyone who requires them. Prices range from approximately £60 to over £1,000 for a single device but will likely be included within your package if you opt for a business broadband deal.

What is a router?

A typical business broadband router will have a visible antenna and multiple WAN ports.

A router is a physical device that distributes data traffic within computer networks.

It acts as a central routing hub that directs the flow of data from multiple devices like smartphones, tablets, laptops, and smart devices to and from the internet or to each other within a local network.

This is akin to an international airport like London Heathrow that routes passenger traffic within the UK (like a local area network) and internationally (like the World Wide Web).

Much like airports and airplanes, routers can send and receive data through the air wirelessly by using a WiFi network that uses electromagnetic waves that travel at high speeds through the air at different frequencies (akin to planes flying at different altitudes).

Routers are tasked with establishing local area networks (LAN) for devices to communicate with each other within a home or business. They also bolster local network security through encryption and firewalls, independent of those set up by a modem.

On that note, routers are frequently mistaken for modems. While both come equipped with cybersecurity features and are integral to any broadband network, they serve very different purposes.

How does a router differ from a modem?

Unlike routers, modems typically lack a WiFi antenna.

While the router is essential for routing data across networks and establishing LAN and Wi-Fi, a modem acts like a gatekeeper/intermediary between the local network and the broader internet and works closely with your ISP (in this instance, a business broadband provider).

Expanding on the London Heathrow analogy, if the router represents the planes and airlines responsible for safely transporting passengers, the modem embodies the customs and immigration officers overseeing the inflow of international traffic.

The modem is positioned at the entry point of any fixed broadband connection entering your business, irrespective of the technology. It’s indispensable for ADSL, Cable, and Fibre optic broadband connections, as it modulates/demodulates the digital signals transmitted and received from your ISP (Internet Service Provider).

Acting as the gatekeeper and ‘ISP agent’ at your property, the modem obtains its designated public IP address from the broadband provider. It’s also tasked with encrypting and decrypting data flowing from the wider web to the devices in your business.

Serving as the ‘border control and international translator’ of your business network, it enforces any firewalls directed towards the broader internet, whether set by the broadband provider or you, the network administrator.

But we digress. Now that you grasp the distinction let’s return to discussing routers 👇

How does a router work?

The router is in charge of directing and diverting internet traffic efficiently and securely within a local network and between the local network and the wider World Wide Web.

While every business or home is recognised by a public IP address, routers must pinpoint the exact device to which they should send data packets, be it for streaming a video call or updating a Google Sheet. This is similar to someone sending a letter to your home address; they still need to specify the recipient’s name to ensure the gossip reaches the right person!

Thankfully, every internet-capable device (e.g. smartphone, tablet, laptop) possesses a unique MAC address. When a device connects to the local network, the router assigns it a unique local IP address based on its unique MAC. Think of this as the device’s ID badge that is recognised within the local network.

To securely translate between a device’s local IP address and the public IP address, the router employs two techniques: NAT and PAT. When data circulates within the local network (i.e., between the router and devices on the network), it uses its local IP for identification. However, when it ventures onto the public internet, the router translates it into a public IP address (valid ID in the wider internet).

So, when John Smith’s laptop sends a request to refresh Google Sheets, the router translates the data into its public format before dispatching it to the Google cloud. Upon receiving the data, the router then translates it back into the local IP format.

In terms of security, the router also encrypts these data packets to facilitate their wireless transmission over a Wi-Fi network, employing WPA/WPA2 encryption. We might overlook it, but wireless technology has profoundly transformed our interaction with devices!

Lastly, routers come equipped with more advanced features. These include supporting VPNs to simulate local connections beyond the physical local network and the ability to establish multiple sub-networks within a primary network (e.g., distinct networks for guests, administrators, and staff, each with varying privileges and quality priorities).

What are ‘business broadband’ routers?

The term ‘business broadband routers’ is relatively self-explanatory: routers specifically tailored to meet the typical demands of businesses and enterprises. Such entities often need more advanced features, heightened security, superior performance, and greater customisability.

For instance, financial trading firms may want a router that supports multiple broadband connections (for redundancy) to make sure they are ALWAYS online, as losing connection during a key trade may be catastrophic. On the other hand, a large enterprise will require routers equipped with multiple Wi-Fi bands and a mesh network to accommodate hundreds of devices simultaneously across a large area.

In contrast, a corner shop that only needs Wi-Fi for its PoS will do just fine with a cheap ADSL broadband deal and the default router that comes with this package!

Business router vs. home router

First and foremost, it’s essential to clarify that business broadband and business routers are available for homes and vice versa. The terms “business” and “home” are primarily marketing labels used to simplify communication and address the needs of each segment.

That said, business routers typically offer:

  • Higher Performance: Business routers are crafted to manage more traffic, ensure faster speeds, lower latencies, and the ability to connect hundreds of devices simultaneously without notable lags. Large enterprises can achieve speeds surpassing even full-fibre broadband through leased lines. Business routers are designed to support such capabilities and are scalable to accommodate network expansion.
  • Enhanced Security Features: Security is often paramount for businesses, so business routers incorporate advanced security measures, including built-in VPN support, intrusion detection and prevention systems, DDoS protection, and 2FA, to name a few. Moreover, manufacturers frequently release firmware updates for business routers, ensuring they remain up-to-date.
  • VPN Support: This feature is vital for enabling employees to connect securely to the business network from remote locations, facilitating a secure remote working environment.
  • Multiple WAN Ports: Some business routers come with multiple WAN (Wide Area Network) ports, which permits the use of multiple internet connections from different providers simultaneously. This ensures redundancy as there is always a fallback connection or provides additional bandwidth if both connections are used at the same time. Occasionally, businesses might opt for two slower, concurrent broadband connections over a single high-performance one.
  • Multiple WiFi bands: Analogous to 5G technology, Wi-Fi operates across various bands, determining signal speed and range. Supporting multiple bands equates to accommodating more devices and diverse Wi-Fi connection tiers.
  • Quality of Service (QoS): Routers with integrated QoS allow network administrators to prioritise specific traffic types. For instance, VoIP traffic can take precedence over standard web browsing, ensuring crystal-clear voice calls. This is vital for businesses demanding consistent performance, such as online retailers and financial entities.
  • Guest Networks: These routers frequently support the establishment of distinct guest networks, crucial for businesses wishing to offer internet access to visitors without granting them entry to the primary business network. Most organisations maintain guest networks for their visitors.
  • Router Management Systems: These are software or cloud-based platforms that allow IT teams to monitor, update, and troubleshoot the supported network(s) remotely. While home routers might also feature apps, their functionalities are generally more restricted.
  • More Expensive: The advanced capabilities and features of business routers come at a price. They are invariably pricier than routers intended for residential use.

How can I get a business broadband router?

The easiest way of getting a business router is when switching business broadband providers.

In the same spirit, tech-savvy small businesses or individuals may prefer configuring their networks and selecting routers tailored to their needs, likely at a lower cost.

In any case, we hope this article has helped you gain a better understanding of business broadband routers! Should you have any lingering queries, be sure to check our FAQ section below

Business broadband routers – FAQs

Our broadband experts answer those frequently asked questions about business broadband routers.

Why are routers and modems kept separate?

It may seem weird at first to keep these devices separate since both play vital roles in security, decoding and encryption within a network (see our Modem vs Router section above).

However, there are key advantages to this separation, primarily centred around flexibility and customisability.

Modems are intrinsically tied to the broadband provider, and troubleshooting them often falls within the provider’s remit. By having an independent router, you gain the freedom to upgrade whenever a new Wi-Fi standard emerges without the need to replace the modem.

Can I install a home router at my business?

Certainly, but it’s essential to consider your specific needs. While homes can indeed install business broadband routers and vice versa, this will not suit everyone.

For instance, a home broadband connection and router will suffice if you run a small corner shop and only need broadband for a Point of Sale (PoS) system.

But if you’re a pro gamer using the highest-spec gaming broadband, you’re unlikely to be satisfied with a typical “home” router and will likely be using an enterprise-grade one.

What is the best brand of business broadband router?

There are many reputable router brands, each with its own product to meet the requirements of each segment.

Well-known brands available in the UK include Cisco, Linksys, TP Link, HPE, DrayTek, Meraki, Netgear, D-Link and Grandstream.

Enterprise vs. business router

It’s vital to understand that terms like “enterprise”, “business”, and “home” when referring to routers are primarily marketing labels. They describe routers tailored to meet the typical needs of these segments. However, they aren’t strictly exclusive to each category. For instance, one could install enterprise-grade routers at home to achieve an unparalleled broadband experience.

In terms of performance, the hierarchy is as follows:

  1. “Residential” routers (most basic)
  2. “Business” routers (mid-range)
  3. “Enterprise” routers (premium tier).

How much is a business broadband router?

The cost of a business broadband router in the UK varies widely and depends on its features, performance, and brand.  It’s essential to assess your business needs to choose the right router within your budget.

For example, a router that supports 10.8 Gbps speeds, 200 simultaneous devices, five Wi-Fi bands including the latest generation 6Ghz Wi-Fi, and two mesh devices currently costs £1,699.99 on Amazon.

Conversely, a more basic router, limited to 750 Mbps and supporting up to 40 devices, is available for £69.99.

How many routers do I need for my business?

This largely depends on the nature and size of your business. A single router may suffice for most small to medium-sized businesses with a single office space and a dozen or more staff.

High-performance business routers can support hundreds of simultaneous devices, support ultrafast speeds, and have redundancy through the use of multiple WAN ports.

However, for large enterprises with multiple departments or expansive public infrastructures such as airports, bus terminals, or university campuses, a single router won’t cut it.

Given the sheer volume of individuals connecting to these networks and the vast geographical spread, multiple routers working in tandem are essential. Such setups also typically demand the expertise of extensive IT teams.

Do business routers come with mesh networks?

Yes, many (if not most) business routers support mesh networks. A mesh network is a system comprising multiple devices (nodes) that work together to distribute the WiFi coverage of a single router over a larger area.

Such a system guarantees consistent and robust coverage, effectively eradicating the notorious “dead zones” frequently encountered in offices with expansive or intricate layouts.

It’s worth noting that support for mesh networks isn’t exclusive to business routers; it’s also a prevalent feature in-home broadband routers.
