...A CASE STUDY OF LOW CSSR ACCOMPANIED BY HIGH RF FAIL PROBLEM STATEMENT: In TIRUPATI MARKET ( Surat 1 MSC) The CSSR and RF fail rate were observed to be abysmally poor values during high call volume period. RESOLUTION STEPS: On inspection of Service Measurements for finding out the contributing factors for RF fail , nothing could be earmarked. All the conventional resources like Power, Packet pipe span, WC, RSSI rise were found within engineered values. That was as per expectation as the Block rate was not high . With this the RF environment was under doubt. Some extensive drive testing and coverage tuning was undertaken but could not yield any improvement. The mystery finally unfolded when we audited the LAPD SIGNALLING engineering ( between AP and BTS). It was found that the BTS which is MODCELL 4 having 4 FA was grown with 1 (64kbps wide) LAPD for each URC . In MODCELL 4 each URC is capable of taking upto 4 carries. When all the associated carrier signalling are imposed on a single URC the signalling load increases manifold and we need to increase the width of LAPD signalling between AP and BTS to 128 Kbps. It is recommended as per SCME ( Lucent DOC NO:401-610-009 Issue 27.0 sep 2004 Section 2-22 Modcell 4.0 (OneBTS) Engineering) that “Signaling Link Width Each fully loaded carrier needs 2 DS0s per signaling link per URC. Each URC supports 1 active signaling link and 1 standby/alternate signaling link. Therefore, if a URC is configured...

...Introduction The evolution of autonomous robots has inspired competitions worldwide, including the most notorious Micromouse Competition. This competition has existed for over 30 years in the United States and hasn’t changed much since the beginning. The goal is simple: the robot must navigate from one corner to the center as fast as possible. The actual final score is comprised of the total time in the maze and the time of the fastest run. The various components include techniques to streamline the methodology and make a proficient automated robot. Maze Solving Strategy The maze solving strategy is comprised of an algorithm. An algorithm is a step-by-step problem-solving procedure, especially an established, recursive computational procedure for solving a problem in a finite number of steps. The implementation The Group chose was a revised version of the bellman flooding algorithm. The algorithm requires around 256 X 3 bytes of memory. The selected microcontroller for implementation had only 256 KB of memory. We need to use software that has exceptional amounts of RAM and ROM memories. To solve the whole maze you will need to set the starting cell to the first cell in the maze. If you want to reverse the path traveled by the robot then you would set the target to the first cell, and the starting cell would then be the center or your current location. The problem statement has been simplified to three rules which we will follow to direct our robot to the center of the maze...

Five men casually walk into the building and ask for their appointments made with the vice president. One man drops his quietly sets his suitcase down beside the security desk. Up they go into VP Wilson’s office. “Are you ready?” Wilson inquires. The men shake their heads and he sends them to the roof. They tear off their suits revealing their advanced tactical gear and begin to open their suitcases and assemble firearms waiting for the signal. Meanwhile, the teams below lock and load also waiting for the signal. The driver of the fifth van nods and honks the horn. “Boom!” A deep thunder echoes throughout the city as the bomb roars. The whole bottom floor swarming with security personnel is...

...biggest problem would be collision if multiple routers are using the same channel a common example of this is Comcast routers are set to use a channel close to the signal for the ps3 so you get a depredation of signal and loss of data packets as the connection goes on. 2. If a previously stated standard is not compatible with your adapter you could have issues with your connection not connecting Lab 6.3 Review 1. Um well I could write a book but simply a guest having access to your network could result in any imaginable results on your network to name a few rootkits,Trojan droppers, Remote Access Terminals, Keyloggers, Viruse’s. 2. Setting a MAC filter is a good way to filter who has access to your network its simply like saying Fred has access to the building with his fingerprint being scanned by a biometric scanner. Although this can be spoofed by spoofing your mac but you would still have to find out which macs are allowed and have to make sure the mac your spoofing is not connected so that you do not receive a duplicate error. Lab Review 6.4 1. A AP’s signal would fade naturally the farther from the signal source you go but with the signal going through walls will further degrade the signal depending on the thickness of the wall. So you would have to account for walls or objects that could further degrade your signal from the source. 2. A student in classroom b connect to AP3. The student in classroom A will connect to AP2.

...Consumers use product to signal status in different ways. They crave status and thus buy more accessible (less expensive), conspicuously branded goods that signal to those below and to other neophytes that they have arrived. But since, many consumers cannot afford authentic goods, they refer to buy counterfeit goods. A counterfeit good is one that seeks to imitate through the use of trademarks or other protected properties without the permission of the owner. Given that the cost of reproducing a brand image on a particular product is fairly low, counterfeit producers can easily duplicate the brand image to send the same signals. Counterfeit producers have lower costs of production that the original producers due to the inferior quality of counterfeits, avoidance of taxes and the lack of costs associated with brand development. It sustains costs arising from attempts to circumvent criminal prosecution and costs associated with creating copies. The demand for counterfeit status goods presents an intriguing paradox between consumption of counterfeit goods and the desire to send status signals. Consumers purchase counterfeit products to convey positive signal to themselves and to others. Particularly in the luxury goods market, consumers knowingly purchase counterfeit products as a social signalling mechanism with low financial costs. Implicit self-esteem is thought to play an important role in predicting status-signalling behaviours as it has been shown to affect materialism...

...The station, a small shack backed by heavy jungle, was a station in name only; for trains only stopped there, if at all, for a few seconds before entering the deep cutting that led to the tunnel. Most trains merely slowed down before taking the sharp curve before cutting. Baldeo was responsible for signalling whether or not the tunnel was clear of obstruction, and his manual signal stood before the entrance. At night it was his duty to see that the lamp was burning, and that the overland mail passed through safely. 'Shall I come too, Father?' asked Tembu sleepily, still lying in a huddle in a corner of the hut. 'No, it is cold tonight. Do not get up.' Tembu, who was twelve, did not always sleep with his father at the station, for he had also to help in the home, where his mother and small sister were usually alone. They lived in a small tribal village on the outskirts of the forest, about three miles from the station. Their small rice fields did not provide them with more than a bare living and Baldeo considered himself lucky to have got the job of Khalasi at this small wayside signal stop. Still drowsy, Baldeo, groped for his lamp in darkness then fumbled...

... The main cause of the misunderstanding was me making the assumption based on previous orders. The customer never said she wanted not breaded, there for I should have asked if I was unsure. A family was sitting at a table, the server kept messing up on little things, like forgetting straws, or extra napkins. The parents at the table found everything and anything to complain about. I noticed they were giving their serve a hard time, so I decided to go over and help her out with the table. I took over the table for her because at that point she was already in tears. So I finish up with the table and I’m standing behind the bar because I’m the bartender, and they used hand signals to ask for their check. I hand signaled them back with what I though was an ‘are you all set?’ hand signal and they took it as they didn’t have a bill because of all the things they complained about. When I went to present them...
