These people will use phrases such as ‘tell me’, ‘let’s talk it over’ and will be best able to perform a new task after listening to instructions from an expert.

These are the people who are happy being given spoken instructions over the telephone, and can remember all the words to songs that they hear!

Adding additional service providers and the hardware associated therewith, will therefore, tax the tower to its physical capacity.

Furthermore, weight is not the only concern, as the antennas and cables increase wind resistance for towers that must withstand 60 mile/hour winds.

Filtering and signal processing circuitry define digital band portions for each of the at least two service providers, and drive the antenna to define at least one individual beam for each individual service antenna having an array of elements arranged in columns of multiple elements and operable to define multiple, individual beams by controlling elements of the columns, for handling signals of at least two individual service providers in a common, analog RF communication frequency band;converter circuitry to convert the antenna signals associated with the beams between the common RF communication frequency band and a common digital IF band representing the signals of the at least two service providers;digital filtering circuitry for processing the duplicated digital IF band and defining individual portions of the respective duplicated digital IF bands, such that a separate band portion is defined for signals of each of the at least two individual service providers;signal processing circuitry for each of the at least two service providers, the signal processing circuitry operable to process channel signals associated with the individual digital IF band portions defined for the individual service providers and to simultaneously drive the antenna to define at least one individual beam for each individual service provider, with at least one of the defined beams being steerable in at least one of azimuth and elevation.

wherein the converter circuitry includes frequency converter circuitry to convert the antenna signals between the frequencies of the common, analog RF communication frequency band and common intermediate frequencies for the band; and further comprising a frequency multiplexor coupled between the antenna and the converter circuitry to provide transmit and receive signals for each of the plurality of communication frequency bands for individual conversion.a plurality of sector antennas positioned proximate the top of the tower, each sector antenna oriented to face a sector and having an array of elements arranged in columns of multiple elements and operable to define multiple, individual beams in that sector by controlling elements of the columns, for handling signals of at least two individual service providers in a common, analog RF communication frequency band; converter circuitry to convert the antenna signals of the sector antennas between the common RF communication frequency band and a common digital IF band;digital filtering circuitry for processing the duplicated digital IF bands and defining individual portions of the respective duplicated digital IF bands for a sector, such that a separate band portion is defined for signals of each of the at least two individual service providers in the sector;signal processing circuitry for each of the at least two service providers, the signal processing circuitry operable to process signals associated with the individual digital IF band portions defined for the individual service providers in the sectors and to simultaneously drive the antenna to define at least one individual beam in each sector for each individual service provider in that sector with at least one of the defined beams being steerable in at least one of azimuth and elevation.generating at least one individual beam for a first service provider in a first band portion with an antenna having an array of elements arranged in columns of multiple elements and operable to define multiple, individual beams for signals in at least one analog RF communication frequency band through control of elements of the columns;digital signal processing the signals associated with the separate digital IF band portions for the first and second service providers and driving the antenna to define individual beams of the first and second service provider; andan antenna positioned proximate the top of the tower and having an array of elements arranged in columns of multiple elements and operable to define multiple, individual beams for signals of at least two individual service providers in an analog RF communication frequency band by controlling elements of the columns;signal processing circuitry for each of the at least two service providers, the signal processing circuitry operable to process the digital IF band and define individual digital IF band portions corresponding to the service providers and to process signals of the service providers associated with such digital IF band portions and simultaneously drive the antenna to define at least one individual beam for each individual service provider wherein at least one defined beam is steerable in at least one of azimuth and elevation.

Still further, ice on the various antenna hardware and cables will further increase physical strain on a tower.

A base station has at least one cellular tower associated therewith, utilizing RF antennas which communicate with a plurality of remote devices, such as cellular phones and paging devices.

Simply building more towers is not a desirable solution.

In addition to the cost to build and maintain the tower, communities are starting to vigorously protest the location of such towers due to their unsightly addition to the landscape.

Odds are, every student in your class has a different preferred learning style, which can make it difficult for you to be the most effective teacher.

However, by trying to incorporate various methods into your teaching, you may be able to reach the majority of your students.
