Increase in system capacity and data rates can be achieved efficiently in a wireless system
by getting the transmitter and receiver closer to each other. Femtocells deployed in the …

OFDMA has been selected as the multiple access scheme for state-of-the-art wireless
communication systems. Efficient resource allocation in OFDMA wireless networks is …

Femtocells are a solution that helps to reduce the capital and operational expenditure of a
mobile network while enhancing system coverage and capacity. However, the avoidance of …

Interference control and quality-of-service (QoS) awareness are the major challenges for
resource management in orthogonal frequency-division multiple access femtocell networks …

Femtocell technology addresses the problem of poor indoor coverage, benefiting both
wireless service provider (WSP) and end users. With the introduction of femtocell, the cross …

In this article, we evaluate the economic gains of a joint deployment of femtocells and
macrocells for the provision of long-term evolution mobile broadband services in urban …

Femtocells are a promising technology to improve network performance with short-range,
low-power, and cost-beneficial small base stations. There will be many prospective benefits …

A fundamental choice in femtocell deployments is the set of users which are allowed to
access each femtocell. Closed access restricts the set to specifically registered users, while …

There are two main access policies (open and closed) to Femtocell Access Points (FAPs),
being closed access the customers favorite. However, closed access is the root cause of …

For two-tier networks consisting of macrocells and femtocells, the channel access
mechanism can be configured to be open access, closed access, or hybrid access. Hybrid …
