Remote and hybrid work depend on a set of technologies that most people use daily without thinking about how they work. Knowing the basics helps when choosing tools, troubleshooting a poor connection or setting sensible security rules for a distributed team.
Video calls
A video call compresses audio and video from each participant's camera and microphone, sends it over the internet and decompresses it on everyone else's screen. Compression software, called a codec, reduces the amount of data needed. When the connection is weak, apps automatically lower video quality to keep audio flowing, which is why the picture blurs before the sound cuts out.
Tips for better calls:
- Use a wired connection or sit closer to the Wi-Fi router when possible.
- Headphones reduce echo, and a basic external microphone often helps more than a better camera.
- Light your face from the front rather than sitting with a bright window behind you.
- Close other bandwidth-heavy activities, such as large uploads, during important calls.
Connectivity
A stable connection matters more than headline speed. Upload speed, which is often much lower than download speed on home broadband, limits how well your own video and screen sharing come across. A mobile hotspot can serve as a backup if the main connection fails.
Cloud collaboration
Cloud document editors let several people work on the same file at the same time. Changes sync through the provider's servers, and version history lets you restore earlier copies. This replaces the old pattern of emailing attachments and merging edits by hand. Good practice includes agreeing where files live, using shared team folders rather than personal ones, and reviewing who has access to sensitive documents.
Chat and asynchronous work
Chat tools handle quick questions, while longer-form updates and shared documents allow asynchronous work, where people contribute at different times. Teams spread across time zones often rely on written updates so that progress does not depend on everyone being online together. Clear channel names, pinned key information and agreed response-time expectations reduce notification overload.
VPNs
A virtual private network (VPN) creates an encrypted tunnel between a device and a network. Organisations have traditionally used VPNs so remote staff can reach internal systems as if they were in the office. A VPN also protects traffic on untrusted networks, such as public Wi-Fi, from local eavesdropping. It does not make a user anonymous or protect against malware or phishing.
Zero trust
A growing approach, often called zero trust, assumes no device or network is automatically trustworthy, inside or outside the office. Instead of granting broad access once someone connects to a VPN, each request to an application is checked: who the user is, whether they passed strong authentication, and whether their device meets security requirements. Access is limited to what each person needs.
Securing the home office
- Change the default password on the home router and keep its firmware updated.
- Use two-factor authentication on work accounts.
- Keep work and personal use separate where possible, especially on shared family computers.
- Lock the screen when stepping away, and be mindful of what is visible on camera.
- Store work files in approved company storage rather than on personal drives.
Ergonomics and wellbeing
Technology is only part of the picture. A screen at eye level, a supportive chair, regular breaks and clear start and finish times help prevent the strain and long hours that can creep in when home and work share the same space.
Choosing tools for a remote team
Prefer a small, integrated set of tools over many overlapping ones. Check that they work on all the devices the team uses, support single sign-on or at least two-factor authentication, and let you export data. Write down which tool is used for what, so new team members can find their way quickly. For more on the underlying services, see cloud computing: common questions answered.
