How To Join For Telecommunication?


Single or split Wi-Fi, Ethernet, 4G ... there are many telecommuting connection modes. In addition, there is access by VPN and with strong authentication for the security layer.
After a year of intensive teleworking, it is never too late to do well, especially as hybrid work will be long-lasting. The emergency configurations of the first containment are replaced by more lasting solutions, guaranteeing comfort in terms of bandwidth and security of use.
In an article of April 30, Arcep, the telecoms regulator, recalls the best practices to adopt to optimize the quality of its internet connection. A box stored under the television is not necessarily the ideal location, especially when there is Wi-Fi access in a house.
Favor a 5 GHz WI-Fi connection
The authority recommends, for example, to place the box in a place as clear as possible, to keep it away from other wireless equipment, to use a Wi-Fi repeater if the surface to be covered is large, or to favor 5 GHz WI-Fi frequencies.
The latest generation boxes allow you to choose between 2.4 GHz and 5 GHz frequencies. However, some equipment has a feature called "Band steering", or "Smart Wi-Fi". In this case, there is no need to configure the frequencies, the router manages automatically.
Finally, and it is obvious, choose a central position to work from home, ideally as close as possible to the workstation. It will then be possible to connect via Wi-Fi, but also via an Ethernet cable.
The cable is not dead, no. Its use can even be recommended in certain configurations or for specific uses. Thus, in the event of access by VPN (virtual private network), the association with Wi-Fi can result in a slowdown in speed. To log in to his emails is acceptable. On the other hand, this is less so for participating in videoconferences, which are very bandwidth-intensive. Disable VPN? It is not recommended, if not impossible if the security policy of the company requires its activation.
One Ethernet cable and multiple connections
The solution will therefore consist in directly connecting the PC and the box by means of an Ethernet cable. This is delivered by default by all access providers with the connection box. The speeds will then be faster with this connection.
Another avenue for optimization: the distribution of uses according to the networks. If your copper (ADSL) connection is slipping a bit, it may be better to spread the bandwidth consumption. Video conferencing can be carried out directly on a Smartphone connected by 4G, or on a PC via the sharing of its mobile connection. One drawback, however: consumption. Arcep reminds that video requires 1 to 4 GB of data per hour, to be deducted from your data envelope included with the mobile plan. In comparison, the VPN consumes less data.
Likewise, audio calls can be made in 4G, but also via the Internet in IP telephony. In addition, it is now an obligation for telecom operators to offer voice or SMS options over Wi-Fi. The smartphones can be configured for receiving and making calls via a default connection to the Wi-Fi network from the box.
When it comes to telecommuting, the network is not everything. It is still necessary to secure the access. VPN is the basic layer. This secure link makes it possible to connect to the company's resources and to encrypt the exchanges. Another protection can complement the VPN, strong authentication.
It is particularly necessary when users connect from personal terminals. This authentication mode is also recommended for PCs managed by the IT department to protect access to sensitive data and applications. The password will be added or replaced by a unique code or biometric data, for example.
