On account of a new type of ventilation,stratum ventilation,tests air distribution in a model office with different air changes,the measure parameters in the experimental study including temperature,velocity and concentration,and studies the thermal comfort in breathing-zone.

The all fresh air conditioning in some area of office can simply improve the air quality of breathing area.

The theoretical analysis and simulation experiment show that it well considers the cell breathing effect.

In this thesis, some characteristics are summarized in WCDMA radio network, such as multi-service and multi-bit ratio, soft handover factor, cell breathing, pilot frequency pollution, self-interference specialty and so on, and at the same time, an in-depth analysis of the difference of WCDMA and GSM in the radio network planning is carried out.

To realize load balancing,researchers introduced the concept of cell breathing in Code Division Multiple Access (CDMA) networks into wireless local area networks (WLANs) due to requiring no special modification of clients.
