While FSO has some potential advantages over traditional modes of communication, it also has several implementation problems. These challenges include (i) FSO integration into prevailing networks; (ii) interference betweenFSO devices, and (iii) intrusion from signal power and ambient light deterioration...
Converging these two models has its set of challenges. These are to conform to government regulations, change in control model retained by the MNOs, and to implement stronger security mechanisms. IMS leans toward the centralized model of control, with some flexibility to allow P2P interactions with...
If the fast ICMP reply function works properly, the high delay and packet loss occur because the STA is in power-saving mode, which does not affect actual services. When the STA runs services, it automatically exits from the power-saving mode. Some handheld PDAs, such as voice phones, barc...
A voice avatar module is connected in a wireless terminal or a server for implementing a voice avatar for multiuser entertainment services allowing voice-based communication over a wireless network. The voice avatar module has a memory including a plurality of voice avatars. A user of the wireless...
The top two challenges are to make sure that there is enough coverage and that the controllers are configured right. Use Cases The tool will be able to troubleshoot the following use cases. • Poor call quality – Red/Yellow QoS – TSM Report – High Channel Utilization – High Roaming ...
Voice services require a short delay, low jitter, and low packet loss ratio, and are second only to protocol packets in terms of importance. NOTE: The bandwidth dedicated to the EF PHB must be restricted so that other services can use the available bandwidth. AF The AF PHB defines that...
