Picocells are already being deployed today, and work very well on 2G networks, However, both picocells and femtocells will both work on 3G networks. Picocells are well suited to cope with the voice and data requirements of business users, particularly in the SME sector, whereas femtocells - which have much higher capacity and are therefore ideal for Mobile TV and other high bandwidth applications - are, in our opinion, more for home users.
So why do we need these new devices? Todays mobile networks are overloaded, particularly in dense areas such as cities. Indoor coverage is a problem too: whatever investment is made in a network, there will always be holes in network coverage caused by obstacles, including thick, insulated walls. The problem is worse with 3G, but is an issue with 2G as well.
Mobile design techniques can go some way to alleviate these problems, but they are not enough. Building more mobile masts is not an option, due to cost, land availability and local pressure.
Wi-fi is not the answer either: it leads to limited handset options whereas with femto and picocells consumers will be able to choose from the entire range of handsets available ; reduced power efficiency battery life is dramatically reduced compared to 2G handsets ; security is complicated; and the increased density of wi-fi routers can lead to interference, causing reduced data speeds and unreliable connections.
Business benefits In comparison, femtocells and picocells have distinct business benefits for mobile network operators and consumers. Operators can dramatically improve their coverage and capacity, offloading demand from the existing macro cell network, thus helping them to improve return on investment from 2G and 3G network infrastructure investment.
However, as with any new market introduction, there are some issues to address, not least of which is the cost of deployment. Installing potentially millions of femtocells in consumers homes is a new business model for mobile operators, and potentially very costly. Essentially, they take care of the small areas that macrocells struggle to reach.
They consist of small low-powered antennas to improve the cellular coverage and capacity in smaller areas. There are three types of small cells: metrocells, picocells, and femtocells. Femtocells are the smallest type of small cell and operate on licensed frequency bands.
They are low-power cellular base stations that require a high-speed broadband connection to improve cell phone signal in homes and small businesses.
They look similar to wireless access points routers , but they work very differently. Routers create a local wireless network and femtocells create a local cellular network. Unlike routers, femtocells use your internet connection and convert it into a reliable cellular signal. Many people are able to get internet in their homes but struggle with poor cell phone signal and dead spots. Femtocells are designed to solve those problems.
They are typically provided by your cellular carrier. To create a cellular network, the femtocell will need to establish a connection with your cellular provider through a broadband internet connection. Most femtocell systems are compatible with cable, DSL, and fiber internet. They will not work with satellite or wireless internet.
An ethernet backhaul will be required to connect the femtocell to your router. After the device has been installed, you will have to register the phone numbers of the subscribers mobile phones that will be connecting to it.
Many devices can be registered, but only handset devices will be able to use the femtocell simultaneously. The other subscribers will have to wait for their turn. Essentially, femtocells are your personal mini cell towers.
As a result, you will no longer have to rely on WiFi calling to avoid dropped calls and unsent SMS messages. But, like with all connectivity devices, you have to be within the femtocells range to maintain a reliable network connection. Typically, they provide a coverage area of 10 meters 32 feet , but it can vary based on the make and model.
If 10 meters is not enough, you might need additional units to cover large indoor spaces. The registered devices should experience a seamless handover when transitioning from the femtocell to macrocell, assuming reliable cellular signal is available.
On the other hand, transitions from macrocells to femtocells can be challenging. However, there are two drawbacks to femtocells. Since they use your internet connection's bandwidth to create a cellular signal, you can experience speed slowdowns when the internet is in use and phone calls are being made simultaneously. Mobile phones would thus maintain the connection on the femtocell as much as possible, but risk dropping the call or having an short outage if the call needs to be switched across to an external macro or microcell.
Femtocell vendors have been promoting the use of their products within the enterprise, in order to displace picocells. Their arguments are based on lower operational costs ease of installation, ongoing maintenance etc. The business case for femtocells in the enterprise is potentially stronger than for picocells, because of the lower installation and ongoing operational costs. It would piggyback on the existing IP network infrastructure provided by the business IT department, who could use mechanisms to prioritise the traffic above mainstream data traffic to ensure high voice quality.
Corporations would expect to benefit from lower cost calls within their enterprise locations in return for installing and maintaining these systems, which would also be offset by not requiring fixed phones at the desk. Table of differences between femtocells and picocells. A significant number of users continue to report poor mobile coverage in their homes. There will always be areas which are uneconomic for mobile operator to reach. They range from rural areas.
The term Enterprise addresses any non-residential in-building including hotels, convention centres, transport hubs, offices, hospitals and retail outlets. It's not just intended for businesses to. Urban small cells sometimes also named metrocells are compact and discrete mobile phone basestations, unobstrusively located in urban areas. They can be mounted on lampposts, positioned on the. A rural small cell is a low power mobile phone base station designed to bring mobile phone service to small pockets of population in remote rural areas.
