7. Security
Because wireless networks rely on radio signals to transmit data, they are not as secure as wire
network. Wireless networks are susceptible to viruses and breaches like eavesdropping and need to be
protected in order to be secure.
There are many security measures to safeguard wireless networks, protect the data, and keep
unauthorized users out. Hotspots, on the other hand, are often free of standard security practices in an
effort to make it easy for anyone to connect. It may be found that some pay hotspots administered by
service providers offer have some level of security, however, when using a hotspot, it’s always a good
idea to be proactive and to employ security measures of your own.
