Things to consider when implementing a new IT network…

Implementing a new IT network is a critical decision that can significantly impact the performance, security, and scalability of your business operations. Whether you’re setting up a network for a small office or expanding to support a growing business, there are several factors to consider to ensure the network is reliable, secure, and future-proof. Here are the key things to keep in mind:

1. Assess Your Business Needs

Before starting, it’s essential to understand the specific needs of your business, including:

• Number of Users and Devices: Consider how many employees will use the network and the types of devices they will connect, such as desktops, laptops, tablets, or smartphones.
• Business Applications: Identify the software and applications critical to your business operations. High-demand applications, such as video conferencing tools, cloud storage, or large data transfers, may require additional bandwidth and network capabilities.
• Future Growth: Ensure the network design can scale as your business grows. Planning for future expansion will save time and costs down the line.

2. Choose the Right Network Architecture

The type of network architecture you choose will depend on your organisation’s size and requirements. Common architectures include:

• LAN (Local Area Network): Suitable for smaller offices where all devices are within a single location.
• WAN (Wide Area Network): Ideal for businesses with multiple locations, allowing communication between offices in different geographical areas.
• Cloud-Based Networks: With more businesses embracing cloud computing, cloud-based networks offer scalability and reduced reliance on physical infrastructure.

Tip: If your business relies on remote work or needs to connect multiple locations, a combination of WAN and cloud-based services may be the best approach.

3. Network Security

Security is one of the most important considerations in any network implementation. Without proper protection, your business is vulnerable to cyberattacks, data breaches, and malware. Key security elements include:

• Firewalls: Ensure you have a robust firewall in place to protect your network from external threats.
• Encryption: Encrypt sensitive data, especially when it is transmitted across the network.
• Access Controls: Implement role-based access controls (RBAC) to limit network access based on an employee’s role or department.
• VPN: For remote employees, use a Virtual Private Network (VPN) to provide secure access to the company’s internal resources.

4. Bandwidth and Speed Requirements

The performance of your network depends on having sufficient bandwidth to handle the needs of your users and applications. Consider:

• Data Traffic: Estimate the amount of data your network will process daily. Activities like video streaming, cloud backups, and large file sharing can require high-speed connections.
• Internet Speed: Choose an internet service plan that can support your network’s bandwidth requirements. Fibre-optic connections offer high speeds and reliability for businesses with heavy data demands.

5. Wired vs. Wireless Networks

Choosing between a wired or wireless network will depend on your business environment:

• Wired Networks: Offer more reliable and faster connections, especially for tasks requiring high data transfers. They are ideal for servers, workstations, and devices that don’t need mobility.
• Wireless Networks (Wi-Fi): Provide flexibility and convenience, particularly for mobile devices and laptops. However, wireless networks can be less secure and slower than wired options.

Tip: Consider a hybrid approach, using wired connections for critical infrastructure and wireless for general office use.

6. Hardware and Equipment

The right hardware is vital for the performance and reliability of your IT network. Key hardware components include:

• Routers: Direct traffic between your network and the internet. Ensure your router can handle the data throughput your network demands.
• Switches: Connect devices within your network. Managed switches offer more control over network traffic, which is useful for larger networks.
• Cabling: For wired networks, choose the right type of cabling (e.g., Cat 8 or fibre-optic) to support current and future data speeds.
• Wireless Access Points (WAPs): If using a wireless network, strategically place WAPs to ensure strong coverage throughout the office.

Tip: For medium to large offices consider a Predictive Wireless Survey, this will help to determine where to place WiFi APs to avoid interference and avoid overlap coverage from other APs. For larger, multi-floor offices, a physical Wireless Survey would be preferable.

7. Network Monitoring and Management

A well-managed network is crucial for maintaining performance and security. Consider the following:

• Network Monitoring Tools: Use network monitoring tools to track bandwidth usage, detect bottlenecks, and identify security threats in real time.
• Performance Optimisation: Regularly review your network performance and optimise as necessary to ensure it meets the evolving needs of your business.
• Backup and Disaster Recovery: Ensure that your network includes a robust backup and disaster recovery plan to minimise downtime and data loss in case of system failure or cyberattack.

8. Compliance and Legal Considerations

Depending on your industry, there may be specific legal and regulatory requirements your IT network must meet, such as:

• GDPR: If your business handles personal data, ensure your network complies with GDPR standards to protect customer privacy and data integrity.
• Industry-Specific Regulations: Sectors such as healthcare and finance may have additional regulations around data protection and network security.

9. Scalability and Flexibility

Your network should be able to grow with your business. When designing the network, plan for:

• Additional Users: Ensure that the network can handle an increase in users without performance degradation.
• New Locations: If your business expands to multiple offices, make sure your network can support remote connections and communications between sites.
• Technological Advances: As new technologies emerge, your network should be flexible enough to integrate new systems and tools.

10. Budget and Costs

Finally, consider the overall cost of implementing a new IT network. Expenses to account for include:

• Hardware Costs: Routers, switches, servers, and other equipment.
• Software and Licensing: Network management software, security applications, and operating system licences.
• Ongoing Maintenance: Factor in the cost of ongoing maintenance, monitoring, and upgrades.
• IT Support: Consider whether your business will need to hire additional IT staff or outsource network management to a managed service provider (MSP), such as Capella.

Implementing a new IT network is a significant investment, but with proper planning and attention to detail, it can provide the foundation for efficient and secure business operations. By considering factors such as scalability, security, bandwidth, and hardware requirements, your business can build a reliable network that meets current demands and supports future growth. Engaging with IT experts or managed service providers can help ensure your network is optimised and well-protected.
