Problems solved by technology

This kind of base station structure consumes a lot of power, is bulky and bulky, and can only be placed in high-end four-wheel drive SUVs. In addition, it is often unreasonable in terms of heat dissipation design and power distribution.
[0005] However, the existing WCDMA downlink field strength measurement devices are generally implemented by wireless terminals, with low receiving sensitivity and slow measurement speed

Embodiment Construction

[0039] The core idea of ​​the portable field strength measuring device of the present invention is to redesign a brand-new baseband unit by changing the original vehicle-mounted integrated base station uplink field strength measurement scheme, and simultaneously send the uplink signal of the mobile phone or wireless network card and the downlink signal of the base station into the The baseband unit processes, measures the received power change, and implements the reporting operation. In order to achieve the receiving sensitivity of the base station, the radio frequency unit adopts a superheterodyne scheme (that is, the uplink and downlink radio frequency signals are down-converted to uplink and downlink baseband signals through frequency mixing technology), and simultaneously receives uplink and downlink WCDMA wireless signals, and the baseband unit adopts band Latched RF cable connection. This not only increases the reliability of the connection, but also has the replaceabili...

Abstract

The invention discloses a portable WCDMA (Wideband Code Division Multiple Access) wireless signal field intensity measuring device. The portable WCDMA wireless signal field intensity measuring device comprises a baseband unit and a radio frequency unit, wherein the radio frequency unit has a tidy super heterodyne structure, so that the size can be reduced, and the same receiving sensitivity as a base station radio frequency unit can be achieved; in the baseband unit, the functions of a plurality of board cards are clipped, so that a brand new wireless portable baseband processing framework is formed on a baseband processing board card; the radio frequency unit is connected with the baseband unit through a radio frequency cable provided with a lock catch, so that field intensity measuring devices of different systems can be switched by only replacing the radio frequency unit; and meanwhile, a charging and discharging management unit of a portable unit for a lithium ion battery is added, so that a battery power supply working mode is supported, and the maneuverability of the field intensity measuring device is enhanced. The portable WCDMA wireless signal field intensity measuring device can meet flexible field intensity measuring requirements in various complex wireless environments.

Description

technical field [0001] The invention relates to the wireless field, in particular to the field of WCDMA uplink and downlink wireless signal power measurement. Background technique [0002] As the WCDMA wireless commercial network tends to be stable and mature, the penetration rate of WCDMA wireless communication terminals, wireless Internet access and other services has greatly increased. In view of the user's demand for measuring the field strength of WCDMA uplink and downlink wireless signals, it is necessary to develop an effective WCDMA uplink and downlink wireless signal measurement and processing device. [0003] In the field of wireless communication, the current devices used to measure the field strength of WCDMA wireless signals include commercial base stations and wireless terminals, and there is no complete portable solution for the measurement of terminal transmit power (uplink) and base station transmit power (downlink). The original purpose of commercial base ...
