The 1900MHz PCS band is divided between six basic bands. The band plan has two 30MHz blocks (15 base, 15 mobile) licensed to an entire "Metropolitan Trading Area" or MTA. These blocks, A and B, were auctioned off. The C block is also a 30MHz block, but was auctioned by "Basic Trading Area", or BTA - a subdivision of the MTA. The C block was set aside for carriers with minority ownership to help open competition. The other three bands - D, E, and F - are 10MHz blocks auctioned by BTA (5 base, 5 mobile). The F block was set aside with similar restrictions as the C band.

Many licenses in the A, B, and C bands have now been subdivided - mostly by their licensees selling part of their allocation. Some are now assigned by BTA or are less than 30MHz. The C band is the most notable division, with the FCC auctioning 10MHz chunks as C3, C4, and C5, or 15MHz divisions as C2 and C1.

Note that the FCC does not divide PCS into discrete channels - leaving that to the carriers based on their choice of technology.

CDMA carriers are 1.25MHz wide and in the arrangement above are allotted 25 channels each. Each block has a guard band at the top and bottom to prevent interference with neighboring carrier blocks. Each CDMA carrier can carry multiple calls through Code Division of the signal.

TDMA carriers are 30kHz and divide the blocks into channels. The A, B, and C blocks have a calculated 499 channels each (unless the carrier has sold of a portion of their frequency) while the D, E, and F blocks have 165 channels each.

Each TDMA channel can carry multiple calls through Time Division of the channel into slots.

GSM carriers are 200kHz and divide the blocks into channels. The A, B, and C blocks have a calculated 74 channels each (unless the carrier has sold of a portion of their frequency) while the D, E, and F blocks have 24 channels each.

Like CDMA and TDMA, GSM allows multiple users on each channel through sharing.

Motorola iDEN is a monopolistic proprietary digital format. Businesses and individual citizens plus government use Motorola iDEN (used by Nextel). The iDEN systems can be a two-way radio for communications when using the "Direct Connect" features. Local and state governments and the Federal Government are using it for routine and emergency communications and for surveillance, investigation, arrests, protective, and administrative operations.

Nextel has plans to break the Motorola iDEN monopoly when they switch to CDMA2000 1X.

Just like cellular, the iDEN (used by Nextel) system overloads and becomes useless during major events or emergencies and has dead spots and drops calls! In addition, the iDEN downlink signals at their cellular base stations significantly degrade performance of other 800 MHz base station receiver systems. It results in loss of coverage and channel quality to public-safety and other types of cellular communications. Thus, iDEN (used by Nextel) has endangered police officers causing the inability for them to communicate.
Interference To 800 MHz Public Safety Radio Systems
Nextel Motorola iDEN Interference

Bearcat scanners and most frequency counters will not detect or scan iDEN systems. However, expensive test equipment by Motorola, SAFCO, Ericsson, and others can be used for analyzing and decoding Motorola iDEN. Modified Motorola radios can also be used.

  1. When first powered up, an iDEN mobile radio scans selected iDEN frequencies and locks on to the designated control channel. The control channel carries information continuously broadcast by the fixed end system regarding system identification and timing parameters for the mobile radio to use when it operates on the system. The control channel also defines the maximum transmit power that radios on the system may use.
  2. In its operational mode, the mobile radio aligns its frequency and transmit timing to the outbound signal received from the fixed end system.
  3. Each mobile radio in an iDEN system is identified by an international mobile station identifier (IMSI), which is assigned to it when it is first placed in service and performs an initial registration with the fixed end system. When making its registration request, the mobile radio supplies its international mobile equipment identifier (IMEI) to the fixed end system. After determining the validity of the IMEI, the fixed end station assigns an IMSI to the subscriber radio.
  4. When operating in a moving vehicle, an iDEN mobile radio can assist the fixed end system in determining when a handover to another cell should be executed. Whenever the mobile radio is not actually transmitting or receiving a signal from the fixed end system, it monitors outbound signals from neighboring cells and measures the received power and signal quality of these signals. When it determines that the signal from a neighboring cell is of higher quality than the signal from the fixed end system in its currently assigned cell, it transmits a handover request to the fixed end system. The iDEN infrastructure can also query a mobile radio for a measurement report. The mobile radio then transmits data back to the fixed end system indicating the received signal strength detected and measured by the mobile radio.

An example of an interconnect call follows:
1. When the mobile radio is powered up, it scans and locks on to a control channel.
2. The mobile radio registers on the system.
3. When it initiates a call, the mobile radio places a service request on the control channel.
4. The fixed end system assigns the mobile radio to dedicated control channel.
5. The mobile radio uses the dedicated control channel to transmit the information required by the fixed end system to complete the call.
6. The fixed end system assigns the mobile radio to a traffic channel to be used for communication of voice or data.

AMPS
The 800MHz cellular band is divided equally between two carriers. The original band plan had 333 channels per carrier, with base frequencies running from 870.030 to 889.98MHz and mobile frequencies 45MHz lower (825.030 to 844.980MHz). Each channel is allotted 30kHz. The center channels, 313-333 and 334-354, are used as control channels for the AMPS system.

When the band was expanded to 832 channels (covering 869.040 to 893.970 base, 824.040 to 848.970 mobile) the original channels remained with 33 channels being added at the bottom and 133 to the top. This led to an "A" band of channels (666-716) dividing the B band.

AMPS channels cannot be used on neighboring cells at the same time. In general, the allotment has been divided into seven pools with each cell or sector using one pool. This allows an approximate maximum of 56 users per cell sector.

CDMA
CDMA carriers are 1.25MHz wide but in the arrangement above are allotted 1.23Mhz (or 41 channels) each. The CDMA carrier is numbered based on the center channel of the carrier, using the AMPS channel numbering. The display above shows how a CDMA system can be overlaid on the existing 800MHz bands. This use starts with the Primary CDMA channel, 283 or 384, and works outward until enough carriers have been added to handle the desired level of CDMA traffic. Channels 691 and 777 are the Secondary CDMA channel.

Note that the "A" carrier has room for eight contiguous CDMA carriers and one carrier at 691. The "B" carrier has room for seven contiguous CDMA carriers and one carrier at 777. While an additional CDMA carrier can be added at 739, it would interfere with the carrier at 777. Note also that a certain number of AMPS channels are not overlaid with CDMA channels. These are used for guard bands between services, AMPS service, and remain available for other possible uses.

Each CDMA carrier can carry multiple calls through Code Division of the signal. CDMA carriers are designed to be reused on neighboring cells and sectors, with a maximum 64 users per carrier per cell sector. 1x CDMA technology doubles the number of possible users on each cell. This allows for an 10 to 20 fold increase over AMPS technology. (Although some capacity is lost when a user is being handed off between cell sectors.)

TDMA
TDMA carriers are 30kHz and follow the same assignments as AMPS channel numbers. As with AMPS, channels may not be reused on neighboring cells or sectors. Each TDMA channel can carry multiple calls through Time Division of the channel into slots. Normally this is 3 slots per channel, but the specification allows for 6 with reduced quality. This allows for a 3 or 6 fold increase over AMPS technlogy.

GSM
GSM 850MHz band carriers are 200kHz and are numbered 128-251 in the cellular band. Both carriers have a maximum of 61 carriers. (The "A" carrier has 128-181 and 233-239, and the "B" carrier has 183-231 and 240-251.) Each GSM carrier can carry multiple calls, but cannot be used on neighboring cells. The GSM carrier is divided by time into frames, allowing up to 24 users per GSM channel. As each GSM carrier consumes 7 AMPS channels worth of bandwidth, this provides for an approximate 4 fold increase over AMPS.

Summary
US providers are currently required to offer AMPS service by the FCC (this requirement is scheduled to sunset in November of 2007). In addition, many carriers offer another technology - TDMA, CDMA, or GSM - to better use their bandwidth. Some carriers have decided to support multiple advanced technologies (such as CDMA and TDMA) in order to serve roamers or during their own transition to other advanced technologies.

Enter a phone number into your cell phone and press the [SND] key. This is what happens next:

1.Scan Control Channels: Your cell phone needs to use the "closest" base station because that's the one with the strongest signal and the one that will give the best connection. To find the closest base station, your phone checks all 21 control channels and determines which has the strongest signal.

2.Choose Strongest: Your cell phone chooses the strongest signal and decides to use that one for placing the call.

3.Send Origination Message: Your cell phone now transmits a very short message (about 1/4 second) that contains the MIN (Mobile Identification Number, aka your cell phone number), its ESN (Electronic Serial Number), and the number you just dialed.

4.Get Channel Assignment: After the cellular service provider verifies that you are a valid, paying customer (based on the MIN and ESN your phone sent), the base station sends a Channel Assignment message to your phone (also a short 1/4-second burst). This message tells your phone where (that is, on which channel) the conversation will take place.

5.Begin Conversation: Your cell phone tunes to the assigned channel and begins the call. The spurts you hear that indicate the phone is ringing at the other end (which is called "ring back") or the busy signal that you hear do not begin until you get to this step. Both of these are transmitted by the base station.
