5 RF PCB Layout Design Guide For user PCB, the characteristic impedance of all RF signal traces should be within 50Ω. In general, the impedance of the RF signal trace is determined by the dielectric constant of the material, the trace width (W), the ground clearance (S) and the height of the reference ground plane (H). The control of the characteristic impedance of the PCB usually in two ways: microstrip trace and coplanar waveguide.

Appendix C GPRS Multislot In the GPRS standard, 29 types of GPRS multislot modes are defined and can be used by mobile stations. The multislot class defines the maximum rate of uplink and downlink. The expression is 3+1 or 2+2, the first number represents the number of downlink timeslots and the second number represents the number of uplink timeslots. Active timeslot represents the total number of timeslots that the GPRS device can use for both uplink and downlink communications.
