Mobile data is growing at such an unprecedented rate that traditional macro-only mobile network can not meet demand, either economically or operationally. This is because it is difficult to make spectral efficiency improvements as we get closer to the theoretical limits for frequencies predicted by Claude Shannon, and it will be impossible to macrocells everywhere capacity is needed due to regulatory and cost constraints.
Solution to give the solid capacity, the effective segmentation of the radio frequency (RF) into smaller samsung 5610 geographical "bins" or coverage areas. (See Simon Saunders' post about management interference). There are a number of ways to do this: one way is to implement active array antenna (AAA). Another is to use metrocells, a type of small cell operating in the public network.
Metrocells appeal to mobile operators for a number of reasons. They let operators strategically and cost-effectively increase capacity for traffic hotspots to improve the quality of experience samsung 5610 (QoE) for end users. Simply put, more bandwidth and better all the time and connection, means a happier customer. samsung 5610
Bell Labs compared the total cost of ownership (TCO) of a macro-only solution to the situation samsung 5610 of a macro and metro-cell solution with and without the rapid introduction of LTE. The Bell Labs study showed that a W-CMDA macro-and metro-cell solution provides a 38% TCO savings over a W-CDMA macro-only solution. When LTE macrocells are posted with W-CDMA and LTE metrocells is the five-year TCO reduced by 45%, compared to implement W-CDMA samsung 5610 macrocells alone. Why and when should they be deployed?
As a capacity solution that metrocells commonly used in high-traffic locations to offload traffic samsung 5610 from heavily loaded or saturated macro sites. To better understand when high-density W-CDMA network will be saturated, samsung 5610 with and without

the launch of LTE, Bell Labs conducted a five-year network simulation with a Tier 1-operator in Western Europe. The simulation samsung 5610 showed that about 2% of all the W-CDMA macro cell sites are already saturated. samsung 5610 Therefore, if you have a high-density network and plans to launch LTE late, you would benefit from inserting W-CDMA metrocells samsung 5610 as a capacity offload solution right now.
If LTE is to be launched in the beginning, it starting to install metrocells now on a more selective basis, then increase the scope of the deployment in 2013 or 2014, when the macro sites begin to saturate. LTE metrocells, on the other hand, should be incorporated into LTE network design from the start, especially for high-traffic-density zones, which are expected to saturate soon after service launch. Where do they make the most sense?
Metrocells used to provide capacity for urban hotspots, improving coverage in indoor locations and expand network coverage and capacity in rural areas. When used to provide capacity for urban hotspots are metrocells deployed in selected high-traffic locations such as city centers, train stations or shopping centers.
When used to improve coverage samsung 5610 for indoor locations can metrocells be deployed within indoor convention samsung 5610 centers, samsung 5610 hotel lobbies, shopping malls, hospitals and office buildings. And they can be targeted at areas with poor or nonexistent macro coverage. In summary, metrocells deployed where they offer a lower TCO than other methods to extend coverage to the building sites.
For coverage and capacity expansion to rural areas, are metrocells inserted into the villages and other rural areas to provide cost-effective voice and packet data services to locations with poor or non-existing macro coverage. Ideally, would be one of the lower frequency bands, such as the digital dividend band 800MHz or 900MHz refarmed GSM spectrum (refarmed used in 3G). Iuh or IUB?
Adoption of a Iuh (3GPP-defined macro) samsung 5610 architecture for the integration of metrocells in a W-CDMA network operators offer several advantages over a IUB (Home NodeB) architecture. These include multi-vendor support, samsung 5610 easier implementation of underground samsung 5610 cells, relaxed samsung 5610 backhaul samsung 5610 requirements, effective metro-to-metro handovers, IP traffic unload subscriber population control and massive scalability. Soft handovers (Shos), supported by the IUB architecture, samsung 5610 is an important element for maintaining samsung 5610 circuit-switched voice calls over macro-to-macro handovers, but is not essential for metrocells used primarily in shared carries only for HSPA services. Should a dedicated or shared bearer samsung 5610 used?
The economic returns of a metro network is driven by the percentage of traffic that it offloads from the macro network - and this proportion is strongly influenced by the frequency allocated to underground layer. Metrocells can be implemented by using a dedicated frequency or by dividing the frequency of the macro network samsung 5610
With a dedicated carrier reserves you a carrier for the exclusive use of metrocells in geography, specially targeted as needing
