Также немаловажную роль играет низкая излучаемая мощность радиопередатчиков абонентских устройств.
This informative article analyzes performance of HS-SFN for macro cell scenario below distinct channels with unique type of schedulers by means of substantial method level simulations and indicates that HS- SFN can improve throughput for UEs in softer handover region from forty% to eighty% without reducing the overall efficiency.
It organizes technological innovation and small business procedures into levels described by actions happening, and it outlines how an company can arrange an interface to communicate amid these layers.
HSPA gives important advancements in data speeds, allowing users to download and add data extra quickly than with prior 3G technologies.
抗干扰能力 ：通过扩展信号频谱，减少了信号的能量密度，提高了信号对噪声和干扰的抵抗力。
This paper offers an overview of The fundamental radio interface concepts for the 3G long-expression evolution strategy, like OFDM and advanced antenna solution, and provides efficiency final results indicating to what extent the requirements/targets could be met.
FDMA is utilized for voice and data transmission. For the duration of this process the overall channel bandwidth is shared by multiple buyers, therefore a range of customers can transmit their data simultaneously. N
The variable-rate character of site visitors channels supply decrease-rate frames for being transmitted at reduce energy leading to much less sounds for other indicators however to get properly received. These factors deliver an inherently click here decrease noise stage than other cellular technologies allowing the IS-95 network to squeeze more buyers in to the exact radio spectrum.
采用先进的信号处理技术 ：如使用多用户检测算法来减少多址干扰，从而降低对发射功率的要求。
In all conditions, the catalog desk may be sorted by its highlighted headings. By way of example, it's possible you'll elect to Show the table sorted by Publication Day or doc range.
So in ability Regulate method transmitter nearer to get more info The bottom station transmits much less ability signal that with the transmitter farther. It's of two forms:
3G, the foremost service provider of transportation and transport management software, proudly provides drayage services in the 3G Transportation Suite. Browse extra. Link with industry experts and peers at events, where you’ll get the knowledge and insights click here necessary to guide in logistics
