The chapter focuses on the changeover of some RRM features such as the packet scheduler into NodeB. The variations in RRM capabilities on the network nodes led to additional modifications of HSDPA air interface including introduction of higher‐buy modulation and coding techniques, and modification with the MAC protocol architecture for enabling the fast scheduling in the BTS.
There is not any delicate handover and for this reason pico-cells overlap in identical setting up and will generate self interference

Foundation station sends the received sign electrical power information into the transmitter and tells to increment or decrement the transmission power appropriately in subsequent transmissions.
The very first version of EVDO (Rev. 0) supplies peak obtain speeds of around 2.4 Mbps and peak upload speeds of around 153 kbps. Rev. B gives even more enhancements here by delivering a multi-provider functionality where a cell cell phone or data card can talk with multiple carriers simultaneously. By undertaking this, Rev. B proficiently enhances the data rate by two or even more instances.
速率分配： 根据调度结果和用户信道条件动态地分配每个用户的数据速率。
ISA-ninety five establishes an architecture depending on the Purdue model that enterprises can implement regardless of here the technological know-how utilised. This gear hierarchy product may also be used across discrete, ongoing and logistics industries.
Adopting sustainable techniques in multi-copyright shipping is ever more critical. Companies can select carriers with environmentally friendly logistics initiatives and optimize delivery routes to cut back their carbon footprint.
Packet Data Protocol: EVDO makes use of a packet-switched data protocol, that means data is split into packets right before transmission. Each packet is encapsulated with information about its resource, desired destination, and sequence within the data stream.
