Embodiment Construction

[0024] For the purposes of this allocation, the International Telecommunication Union ['ITU'] divides the world into three regions. The Indian subcontinent belongs to region 3 of this classification, while Europe and Africa belong to region 1, and the Americas belong to region 2.

[0025] The design and availability of devices supporting the various platforms of cellular mobile telecommunications must be compatible with and based on this global spectrum allocation.

[0026] In summary, the available and emerging platforms can be divided into [GSM & WCDMA] and CDMA 2000 from a spectrum allocation point of view.

[0027] The global spectrum allocation for such platforms is shown in Fig. [Table] 1. As can be seen from the analysis of the table, the two basebands of the spectrum allocated to GSM / WCDMA are the 900MHz cellular frequency band and the 1800MHz DCS frequency band.

[0028] figure 2Depicts the actual frequency band allocation and deployment of the uplink and downlink ...

Abstract

A method and architecture for pairing of Guard Band Frequencies in PGSM / EGSM 900 MHz and DCS 1800 MHz Bands, as also in US Cellular Bands and US PCS Bands, for effecting duplexed cellular mobile telecommunication services like I-Den, GSM, PGSM, EGSM, CDMA, CDMA 2000, UMTS & WCDMA & any other duplexed use in the guard bands. The method and architecture- of the present invention / innovation leads to two additional interspersed Bands available for exploitation of mobile cellular telecommunication systems, leading to an inherently additional utilization of spectrum that was unutilized in the Art, leading to a near optimal and efficient utilization of a scarce natural resource like spectrum. Further, this present embodiment leads to a balanced link compared to the embodiment in the Art.

Description

technical field [0001] One for pairing guard band frequencies in PGSM / EGSM 900MHz and DCS 1800MHz bands and US Cellular band and US PCS band to implement in guard bands such as I-Den, GSM, PGSM, EGSM, CDMA, CDMA 2000, Methods and architectures for duplex cellular mobile telecommunication services such as UMTS and WCDMA and any other duplex applications. Background technique [0002] Over the past decade, wireless cellular telecommunication technologies and applications have experienced unprecedented development and growth. One of the fundamental limiting factors and challenges facing the field is the availability of valid carrier frequencies, also commonly referred to as spectrum. This is a natural resource, and like all such natural resources is limited, it needs to be used very sparingly and efficiently. [0003] During these years, the world's telecommunications authorities have managed and allocated various frequency bands in different regions for different classes of ...
