A system and method for a simultaneous examination of synchronized forward and reverse link data of a telecommunication network is provided. An RF optimizer system first gathers inputs from both the forward link data as saved by a mobile diagnostic unit (MDU) and the reverse link data as provided by a mobile telephone exchange (MTE), and then merges and synchronizes these two distinct and individual data sets. Various parametric data can be viewed simultaneously from different perspectives (map, grid, graph, message views) with each individual perspective to be synchronized with all others.

The electrostatic transfer type liquid electrophotographic printer of claim 1, wherein the concentration control unit is spatially separated from the plurality of development units. 5. The electrostatic transfer type liquid electrophotographic printer of claim 1, wherein the concentration control unit controls the concentration of the toner images in the range of 20-40%. 6. The electrostatic transfer type liquid electrophotographic printer of claim 2, wherein the concentration control unit comprises a concentration control belt circulating by being supported by at least two rollers, the concentration control belt being installed with a predetermined separation gap from the photoreceptor web; and wherein the concentration control belt removes excess liquid carrier from the photoreceptor web, and retains an appropriate amount of liquid carrier thereon to allow the liquid carrier to permeate into the toner images. 7. The electrostatic transfer type liquid electrophotographic printer of claim 2, wherein the concentration control unit comprises a concentration control roller having a diameter at least two times larger than the diameter of the developer roller, and rotating while being separated by a predetermined gap from the photoreceptor web; and wherein the concentration control roller removes excess liquid carrier from the photoreceptor web, and retains an appropriate amount of liquid carrier thereon to allow the liquid carrier to permeate into the toner images. 8. The electrostatic transfer type liquid electrophotographic printer of claim 4, wherein the concentration control unit comprises: a carrier reservoir for storing a liquid carrier; and a concentration control belt installed in the carrier reservoir with a predetermined separation gap from the photoreceptor web, the concentration control belt circulating by being supported by at least two rollers, and wherein the concentration control belt allows the liquid carrier supplied in the gap between the photoreceptor web and the concentration control belt to permeate into the toner images. 9. The electrostatic transfer type wet electrostatic printer of claim 8, wherein the concentration control unit further comprises a carrier supply unit for supplying the liquid carrier in the gap between the photoreceptor web and the concentration control belt. 10. The electrostatic transfer type liquid electrophotographic printer of claim 4, wherein the concentration control unit comprises: a carrier reservoir for storing a liquid carrier; and a concentration control roller installed in the carrier reservoir to be operative to rotate while being separated by a predetermined gap from the photoreceptor web, the concentration control roller having a diameter at least two times larger than the developer roller, and wherein the concentration control roller supplies the liquid carrier in the gap between the photoreceptor web and the concentration control roller, and allows the supplied liquid carrier to permeate into the toner images. 11. The electrostatic transfer type liquid electrophotographic printer of claim 6 or 8, wherein a blade is installed in contact with a lower portion of the concentration control belt to remove a liquid carrier from a surface of the concentration control belt. 12. The electrostatic transfer type liquid electrophotographic printer of claim 6 or 8, wherein the concentration control belt circulates in an opposite direction to the circulation direction of the photoreceptor web. 13. The electrostatic transfer type liquid electrophotographic printer of claim 6 or 8, wherein the gap between the concentration control belt and the photoreceptor web is in the range of 50-100 μm. 14. The electrostatic transfer type liquid electrophotographic printer of claim 6 or 8, wherein a surface of the concentration control belt is charged to a first potential having the same polarity as the toner. 15. The electrostatic transfer type liquid electrophotographic printer of claim 7 or 10, wherein the concentration control roller rotates in an opposite direction to the circulation direction of the photoreceptor web. 16. The electrostatic transfer type liquid electrophotographic printer of claim 7 or 10, wherein the surface of the concentration control roller is charged to a first potential having the same polarity as the toner. 17. The electrostatic transfer type liquid electrophotographic printer of claim 1, further comprising a setting roller for setting shapes of the toner images formed on the photoreceptor web and passed through the concentration control unit, a surface of the setting roller being charged to a second potential having the same polarity as the toner.
