As part of the development of digital tools, applied to the management of the customer relationship, Société Générale has equipped its 30,000 employees with connected tablets to acclimatize them to digital uses. But also for them to promote the bank’s mobile and Internet applications to customers.
For this, the banking group has equipped 4G + routers with the operator Bouygues Telecom. In 6 months, all 3,500 branches (Societe Generale and Crédit du Nord) have been equipped with very high speed internet access.
An interconnection available in a few days
The main interest of a 4G router is its speed of implementation. Indeed, a higher speed connection to ADSL, or even in the best conditions equivalent to optical fiber, can be created in a few days, or even in a few hours if a company already has a suitable SIM card. As a reminder, when a company wants to install a very high-speed fixed connection, it must in particular order the un bundling to its operator, which can then take several weeks.
Therefore, companies benefit from the same services available on a shared fixed access such as a private network (VPN / MPLS) and the prioritization of applications through the definition of several classes of services. Within a VPN, a company can prioritize its voice flows or customer relationship management for example, to the detriment of browsing the Internet, less critical.
In general, companies use 4G routers, in addition to other connections (fiber, xDSL), according to three recurring use cases. First, in the majority of situations, operators find that companies are equipped with 4G routers to create a backup link in case of failure of their wired link. In case of failure of the fixed service, the mobile solution then takes over instantly.
According to a study by the Nemertes Research Research Institute, the average duration of an Internet service interruption is more than 16 hours. In addition, a site suffers on average 3.6 cuts per year, thus totaling nearly 60 hours of interruption. “Many of these cuts are the result of loss of electricity at the site itself due to natural disasters, work that has led to a deterioration of the fixed link, or a supply problem from the service provider itself” says John Burke, senior analyst at Nemertes Research. The 4G router is then a satisfactory backup in two of these three typical failures.
Furthermore, outside of these cut-off times, the 4G router is active and can be used as an additional interconnect link, thus offloading the main access.
Connect temporary and underserved sites
Connecting a temporary site to the Internet is another frequent use of 4G routers, providing Internet service at events, on construction sites, and so on. where a fixed connection is not available. This mobile solution is adapted to punctual needs, not lasting more than a few months. There is indeed no economic interest to install a fixed link on which the company will have to engage with an operator for a longer period.
In addition, in some cases a 4G router can substitute for a wired link, when an agency is underserved by the DSL or fiber optic, or that the rates are not sufficient. Fixed mobile replacements are now marginal, but the development of 5G, with the increase in speed, the reduction of latency and the possibility of finding quality of service, should see this case. application progress.
In any case, if a 4G router provides connectivity quickly in the geographical areas covered, it has some limitations. On the one hand, the communications transit on a shared network, on which it is not possible today to apply quality of service.
On the other hand, each router is limited in the number of concurrent users that can connect to it. Currently, equipment manufacturers such as Huawei (used by Orange Business Services and Bouygues Telecom Entreprises) host up to 64 users at the same time.
Finally, like private phone packages, the use of a 4G router requires a SIM card and a suitable data plan. While the needs depend on the activity of each company, operators believe that companies consume an average of at least 50GB of data per month.
