Cellular Overview Introduction A cellular mobile telephone system divides the service area into small, low power radio frequency coverage areas called cells. A cellular system consists of a more or less continuous pattern of these cells, each having a 1 to 40 mile radius (typically 5 - 10 miles). Within each cell is a centralized cell site with an elevated antenna and a building. The building houses a base station with transceivers and related control equipment for the channels assigned to that cell.
Cellular Overview TDMA M3090/M3097 Introduction are defined in Figure 1. The cellular radio frequency spectrum has been divided by the FCC into two equal segments or bands to allow two independent cellular carriers to coexist and compete in the same geographic coverage area. Each band occupies one half of the available channels in the cellular spectrum.
Service Manual Cellular Overview Introduction naling required to establish a telephone call. Control channels are used to send and receive only digital data between the base station and the cellular telephone. Voice channels are used for both audio and signaling once a call is established. The 21 control channels in each band may be dedicated according to two different applications: access and paging channels.
Cellular Overview TDMA M3090/M3097 Introduction applications for each carrier. In 1987 the FCC expanded the cellular spectrum (Expanded Spectrum) from a total of 666 channels to 832 channels, allowing for an increase of 83 voice channels for each carrier. But the number of control channels remained constant, 21 control channels for each carrier.
Service Manual Cellular Overview Analog Cellular Analog Cellular central controller (switch). The simplified block diagram on page 1 - 7 illustrates an imaginary layout of one side (Band A, or Band B) of a hypothetical service area. The hexagons represent cells, and some of the cell sites shown here also illustrate the fact that an antenna tower and set of base stations are associated with each site.
Cellular Overview TDMA M3090/M3097 Analog Cellular the complement of the assigned DSAT. SAT (Supervisory Audio Tone) and DSAT (Digital SAT) The Supervisory Audio Tone (SAT) is one of three frequencies around 6 kHz used in AMPS signaling. On NAMPS channels SAT is replaced by one of seven sub-audible digital equivalents or vectors called DSAT.
Service Manual Cellular Overview Analog Cellular Analog Cellular Signal Summary (AMPS and NAMPS) The diagrams on the following pages outline the various uses of the signals employed in cellular systems. These signals include: SAT (Supervisory Audio Tone) 5970 Hz, 6000 Hz, or 6030 Hz. Used in AMPS for channel reuse, muting audio (squelch), and call continuation [typically ± 2 kHz deviation].
Cellular Overview TDMA M3090/M3097 Analog Cellular Total deviation of two or more signals is cumulative. Step 5. Decision point. Can the overhead message from the strongest control channel be decoded? If not, go to step 6. If it can be decoded go to step 8.* Step 6. The telephone tunes to the second strongest channel. Step 7. Decision point. Can the overhead message stream be decoded? If not, go to step 12. If it can be decoded, go to step 8.* Decision point.
Service Manual Cellular Overview Analog Cellular cessful completion of either steps 5 or 7, the telephone scans a set of paging channels, tunes to the strongest, and attempts to decode the overhead message train. The procedure is exactly equivalent to that followed for the access (control) channel. Also at this point, in a few larger systems, the telephone is commanded to identity itself (transmit) and thereby indicate its location in the system.
Cellular Overview TDMA M3090/M3097 Analog Cellular Placing a Call (Mobile to Land or Mobile to Mobile) When the cellular telephone user originates the call, the cellular telephone re-scans the access channels to assure that it is still tuned to the strongest one. The cellular tele- phone then transmits data at the rate of 10 kilobits per second on the control channel to notify the switch of its mobile identification number (MIN) and the number it wants to reach.
Service Manual Cellular Overview Analog Cellular The cellular telephone tunes to the assigned voice channel and verifies the presence of the proper forward SAT frequency (or DSAT message). If SAT (DSAT) is correct the telephone transponds SAT (DSAT) back to the cell site and unmutes the forward audio. The cell site detects reverse SAT (DSAT) from the cellular telephone and unmutes reverse audio.
Cellular Overview TDMA M3090/M3097 Figure 8. Land to Cellular Telephone Call Processing Landline Network The landline caller dials the cellular telephone number. The Public Service Telephone Network (central office) forwards the call to the central controller (switch). Switch / Cell Site Cellular Telephone DATA Overhead data is sent out on the control channels. FOCC & RECC The switch receives a call from land. The switch pages the cellular telephone.
Service Manual Cellular Overview Analog Cellular Power Steps As a call progresses, the cell site continuously monitors the reverse channel for signal strength. Every cellular telephone has a number of power steps ranging from full power (3 watts in a mobile and .6 watts in a portable) down to as low as about half a milliwatt. In reality all cellular telephones have eight power steps, but portable models are prevented from using the two highest power steps by the cell site.
Cellular Overview TDMA M3090/M3097 Figure 9. Cell Site Handoffs Cellular Telephone Switch / Cell Site Conversation in progress. The voice path is unmuted. VOICE + (D)SAT The cellular telephone acknowledges the handoff request by sending a10 kHz signaling tone for 50 msec or a DST message. The voice path is muted while sending ST. The telephone drops the voice channel and keys up on the new voice channel frequency. The telephone sends the newly assigned SAT (DSAT). Conversation in progress.
Service Manual Cellular Overview Analog Cellular Call Termination When the call is terminated by the landline caller (not the cellular telephone user), the central controller (switch) issues a release order to the subscriber unit. The cellular telephone acknowledges with a 10kHz signalling tone burst for 1.8 seconds and the cellular telephone ceases transmission. signalling tone burst for 1.8 seconds, indicating a call termination request to the switch.

Service Manual Cellular Overview Digital Cellular Digital Cellular Multiplexing Using a single frequency to carry two or more communication links (e.g., conversations) is called multiplexing. There are two types of multiplexing that are feasible for cellular: code division multiplexing and time division multiplexing. Both code division multiplexing and time division multiplexing digitize voice before transmitting the signal.
Cellular Overview TDMA M3090/M3097 Digital Cellular line, such as that shown in the accompanying illustration, will be produced. audio. TDMA (Time Division Multiple Access) In the illustration on page 1 - 19 we saw how speech could be sampled at some rate. Suppose we take only one of every three samples. If our sampling rate is fast enough, and if we can compress the samples, it turns out that we can interleave several different conversations (communication links) on a single frequency.
Service Manual Cellular Overview Digital Cellular voice samples as viewed on oscilloscopes, are clearly shown to be nothing more than varying voltages produced by microphones. Instantaneous samples are discrete voltages. It has been shown that if the sampling rate is fast enough, it is possible to make a faithful representation of each conversation.
Cellular Overview TDMA M3090/M3097 Digital Cellular frequency. The IF is processed in the IF strip, which provides filtering and amplification. A discriminator retrieves audio from the IF and the varying voltages of the audio are used to drive a speaker TDMA Radio TDMA radios use the same circuitry as analog radios, for the most part, but also have additional circuitry to convert analog audio to digitized form and vice versa, and to select the appropriate time slot.

General Description Antenna Circuit NADC IC Two RF ports are designed in this transceiver; internal antenna and external antenna. An RF switch controls which antenna path is going to be used during operation. Since this transceiver operates in two frequency bands(800MHz and 1900MHz), the switch also controls the RF frequency paths. Only one RF port and frequency band is used at a time, therefore, only one RF switch configuration is used while the other is irrevelent. The NADC/PDC ZIF/SYN is a 2.
