6.10. Microcells
Microcells are designed for use by companies. They can serve the
company’s internal network provide access to its intranet whilst also
allowing telecom equipment (smartphones, tablets, etc.) to connect
directly to the operators’ networks. In other words, they must deliver
two forms of access simultaneously, which may be achieved by two
distinct SSIDs on the same access point, or else by using
virtualization. By virtualization, we are able to put in place two virtual
access points on the same physical access point. In both cases, the two
networks – the company’s and the network that connects to the
operator network – need to be perfectly separated from one another;
this is known as isolation of the two networks.
Microcells also use Wi-Fi techniques, and rely on the new
standards to deliver the quality of service necessary to handle
telephony and video with a good level of quality.
Engineering plays a very important role for the installation of
microcells, because a company needs to cover all of its offices,
workshops and boardrooms, with all of the problems caused by walls,
floors and other obstacles. It is essential, in this context, to minimize
interference between the access points, whilst ensuring overall
coverage with as high a data rate as possible.
6.11. Wi-Fi Passpoint
Passpoint is an architecture proposed by the Wi-Fi Alliance. The
Wi-Fi Alliance was set up when Wi-Fi was first proposed with the aim
of promoting this technology. It has had a significant part to play in
the success of Wi-Fi and the introduction of various standards, such as
WPA2, which offers high security in Wi-Fi networks, or the
introduction of priorities with IEEE 802.11e.
Passpoint is a solution which helps to relieve the workload of
3G/4G antennas by offloading, giving users the option of connecting
in a way that is totally transparent to the 3G/4G networks, using Wi-Fi
networks. In other words, the client will not know how s/he is
