Antenna Tip of the Day!

Bandwidth of Wire Antennas can considerably be increased by making them conical in shape.

Antenna Tip of the Day!

Bandwidth of wire antennas such as monopole and dipole can be increased by increasing their diameter.

A criteria generally used for antenna designs is a VSWR <= 2 or a Return Loss >= 10 dB over the desired frequency band. In this case the power delivered to the antenna will be 89% or more across the whole band. 

Handover Optimization in GSM

Optimizing Handover procedures in a telecom network helps a great deal in decreasing call drop rate, increasing HSR and thus improving mobility and quality of the network. Handover parameters like RxQual thresholds at which handover should be triggered, timers that control the repetition of Handover requests to neighbour cells, penalty on source cells to curb the handover requests on congested cells are some of the areas that create a significantly positive impact on network KPIs.

Fast Drive Investigation (FDI)

Fast Drive Investigation (FDI) is a post processing tool developed by engineers of Pakistan. It is the only product in the field of  RF Optimization fully developed locally by a team of experienced engineers. The tool is in use by telecom operators in Pakistan and Afghanistan and has received tremendous appreciation and acclaim for its world-class algorithms and convenience. The features of the product include overshooters identification with footprints, quick neighbor audit feature, mesh analysis for multi-server environment, low-coverage zones depiction, graphical analysis of various KPIs etc with a standard comparable to international software. Other tools advantageous for Optimization engineers are also included in their product line. More on this can be read from their website. Trial version of the software is not available which needs to be developed to increase its propagation and usage worldwide.

Gain is the product of directivity and radiation efficiency only. If Gain is multiplied by the reflection efficiency, it becomes Absolute Gain (called Realized Gain in HFSS).

3G Auction in Pakistan - Get Ready

Reliable sources from the PTA have confirmed that preparations for the long-awaited 3G spectrum has once again started with a hope to complete the entire process within 6 months from now, a report on the back page of today's Express Urdu edition said. A similar report was published on Express Tribune on 18 Aug 2012 (http://tribune.com.pk/story/423595/3g-auction-process-to-be-completed-by-december/) that quoted Farooq Awan, Chairman PTA, as saying that he was quite optimistic about the introduction of 3G/4G services by December 2012.

The government should realize the importance of this technology, that would serve as catalyst for the nation's economy and employment in all sectors of the industry, not just the technical sector. A plethora of business activities is sure to start after the auction that on one hand would give a strong boost to the economy and on the other hand would be introducing an altogether new customer experience with stronger data speeds. With Android phones already in the market, online shopping, navigation services and social networking applications are expected to be the upcoming market that universities, students, entrepreneurs and venture capitalists in Pakistan should start preparing for!
