What is femtocell?
As with the growing need to get connected all the time increasing. This results in the femtocell. A femtocell is a small device that is installed inside a premise. Maybe it is in the office or home that gives more coverage to the mobile operator and better voice quality to a subscriber. It acts like a BTS or access point for the mobile device, which is a few meters of the radius. On another side, it connects to the mobile core network over a broadband internet connection for signalling and voice. Femtocell is very useful for mobile subscribers, having a high-speed broadband internet connection, but low cellular signal strength or no signal. Maybe because the premises in the basement of the building or mobile company tower is on a distance.
How to get and configure femtocell?
The femtocell option is available from the same mobile operator for an existing SIM card. On request, the service provider installs the device and does configuration in the device to use the gateway. After installing devices, there is a new network that will be shown on the network list for a new small tower. Mobile tries to attaches to a new network (maybe manually you need to select). If all is good, the phone connects to the femtocell. SMS and Voice call works as they are working with a cellular tower.
Facts about femtocell.
There are many things which need to know about new devices before going to buy. Various factors one should consider before using a new option for cellular connectivity.
Do call disconnect while moving from Femtocell to the normal tower?
For a mobile operator, a new device is like any other cell tower. Like other towers, hand-in and handout procedures work in the same way. So the call will not disconnect, if someone moves from away or comes in range, during a call.
Is femtocell a low-cost option?
It may depend on the mobile operator. An operator saves the cost for a base station by using femtocell. A base station requires continuous power consumption and monitoring of mobile towers. The new device may reduce the cost. But still, it is the decision of the network provider for the cost.
Is Call Quality always better with femtocell?
If we see on the radio connection side, then signal strength is good within a small area. So looks call quality will always be good. But there comes another shared connection between femtocell and network, which is broadband internet. Other home equipment( e.g someone watching a movie or on an internet call) also shares the same broadband. While making a call, if the available bandwidth is lower than a certain range, then call quality will below. So buying a good quality internet is a must for good quality.
Is Femtocell is same a WiFi Calling?
For a mobile subscriber, both are similar. Even WiFi calling is better in a way, that it does not require an additional device. The same wifi router will also work as an antenna for cellular connectivity. But on the network-level, these two are totally different concepts. For WiFi calling, a subscriber is limited to a 4G sim only. 3G or 2G sim will not work for wifi calling. In femtocell, a user has to deploy an additional device in-home or office, no change in phone or no extra app is needed. While in WiFi calling, the mobile operator needs to deploy a gateway called ePDG and the device should have support for Wifi calling. Maybe the operator provides an option to download an app to enable WiFi calling or existing phones.
Is femtocell uses VoIP?
VoIP is Voice over IP network. With femtocell, the call is going through an IP based internet connection to the mobile operator network. It may look like VoIP. VOIP does not just call over IP, it having various protocols involved (e.g SIP, GTP ), etc. Device vendors may use existing VoIP technologies or other specific interfaces for voice signalling and media transfer with the core network.
