Wireless technology

Cellular networks, also known as mobile phone networks, now handle much more than voice calls. Faster data speeds and better devices like smartphones and tablets make them vital for businesses needing flexible connectivity.

Cellular network technologies

Technologies connected with cellular phone services include:

• 5G - matches ultrafast broadband speed; coverage is rolling out in the UK
• 4G - delivers fast broadband-like performance for most data needs
• 3G - older standard for basic data which is being phased out
• global positioning system (GPS) - pinpoints device location accurately
• short messaging service (SMS) - for text messaging
• multimedia messaging services (MMS) - for exchange of images, audio and video
• global system for mobile communication (GSM)/general packet radio service (GPRS) - legacy data services, largely replaced by 4G/5G

What cellular networks offer

Cellular technologies offer additional ways for networking mobile devices. The worldwide coverage of cellular networks means that such facilities are often available in places where other types of networking, such as local area networks (LANs) and wireless LANs, cannot reach. As a result, you can use these technologies alongside local networks as a means of 'roaming' - maintaining contact while travelling.

Smartphones and tablets give staff access to the internet, email, apps and online tools anywhere with signal. This supports remote working and real-time tasks like ordering, billing and online buying. 4G and 5G provide the speed for advanced apps. They outpace older GSM/GPRS, offering better value despite higher initial data costs.

Disadvantages of cellular technology

Despite many benefits, cellular solutions have drawbacks that could affect your budget and performance. For example:

• costs for handsets data plans vary enormously
• streaming or heavy data use can get expensive
• speeds depend on location and network congestion
