2G GSM Interview Preparation: Currant channel definitions -------------------------------------------------------------------------------------- 1.Time: It is system time of computer. 2.Cell name: It displays the name of the sector which is serving according to the cell file that is loaded in TEMS. 3.CGI : It stands for the Cell Global Identity which is unique for every sector of the site. It consists of MCC,MNC,LAC,CI. MCC: Mobile Country Code 0 – 999 MNC: Mobile Network Code 0 – 99 LAC : Location Area Code 0 -65535 CI: Cell Identity 0 – 65535 •Cell GPRS Support: Tells sector is having GPRS or not. Values are Yes or No . •Band : It tells in which Freq. Band mobile is operating e.g. GSM 900/ 1800. •BCCH ARFCN: It tells by which BCCH is the mobile station getting served. •TCH ARFCN: On which Traffic Freq. call is going on. •BSIC (Base Station Identity Code) : It is combination of Network Color Code (NCC) (0 – 7) & Base Station Color Code (BCC) (0 – 7). e.g. 62. It is decoded by mobile on every Sync. Channel Message. •Mode: It is shows in which state is mobile operating, Idle, Dedicated & Packet. •Time slot: On which time slot of current TCH call is going on. Viz. time slot no. of TRX. •Channel Type: Type of channel mobile is getting now. Like BCCH / SDCCH/8 + SACCH/C8 or CBCH / TCH/F +FACCH/F +SACCH/F. •Channel Mode : Shows mode of coding like Speech Full Rate of Half Rate. •Speech Codec: It shows FR for Full Rate, HR for Half Rate & EFR for Enhanced Full Rate. •Ciphering Algorithm : It shows ciphering algorithm used by the system to protect data for privacy. E.g.

E.g. 2. •Hopping Channel : It shows that current sector is having hopping feature or not. Values are Yes or No. •Hopping Frequencies : It displays no. of freq. on which mobile is allowed to hop. viz. MA List for hopping of that sector. •Mobile Allocation Index Offset (MAIO): It is the number which tells from which freq. from given MA list for sector hopping has to be started. E.g. 0 means sector will start from first freq. to hop. •Hopping Sequence Number (HSN) : Indicates sequence in which frequencies are allowed to hop from the MA List. 0- 63. 0 for Cyclic Hopping, 1 – 63 random hopping sequences. #GSM #2GInterview #TelecomJobs #TelecomRF #RadioFrequencyJobs #Jobs #Optimizer #TeamLead #RFManager #DriveTestEngineer #Globalsystemformobile

A network engineer interview is a process in which candidates for a network engineering position are assessed by potential employers. The interview typically evaluates both technical skills and soft skills necessary for the role. The interview process may include: 1. Technical Questions: Questions that assess the candidate's knowledge of networking concepts, such as TCP/IP, subnetting, routing, switching, firewalls, VPNs, and network protocols. 2. Practical Problems: Scenarios or problems that require candidates to demonstrate their problem-solving skills, such as troubleshooting network issues or designing network architectures. 3. Behavioral Questions: Questions that explore how the candidate handles various situations, teamwork, communication, and other soft skills. 4. Hands-On Tests: Practical assessments that may involve configuring network devices, using network simulation tools, or writing scripts to automate network tasks. 5. Experience and Projects: Discussion of the candidate’s previous experience, projects they have worked on, and specific technologies they have used. A network engineer interview aims to ensure that the candidate has the necessary technical expertise and the ability to effectively apply their knowledge in real-world situations. Note: interview is not always about your skills its about your behaviour, professionalism, attitude, body language and commitment.

I solve company's IT Infrastructure problems and coach IT Professionals on building their career. Network Architect | .ı|ı.ı|ı. CCIE EI #65745
10 things every Network Engineer should do before an interview: Ensure that you have a strong understanding of fundamental networking concepts like TCP/IP, subnetting, VLANs, and routing protocols (e.g., OSPF, BGP). Be prepared to demonstrate your problem-solving skills by practicing common network issues and their resolutions. You can even use Cisco Packet Tracer. Learn about the company’s history/products/services. Understand as much as you can about your probable future employer. Review the job listing to identify the key skills and qualifications required for the position. Always highlight what they consider to be preferential for the role and you already have it. Understand any specific networking challenges or projects the company might be facing by reviewing their blog, press releases, or news articles. Practice answering common interview questions related to network engineering. You can do this using a mirror or ask a close friend, a family member to help you practice the interview. Be familiar with everything on your resume, including your previous projects, experiences and skills. If you have irrelevant things for that specific role, remove it from your resume. Utilize salary research websites like Linkedin, Glassdoor and Payscale to get insights about the market value for that specific position. Have a clear number for your salary before the interview. Don’t look at the gross salary because that’s your salary before deducting taxes. always look at the net salary because that is what will stay in your pocket. Think beyond salary and consider total compensation packages, including benefits such as health insurance, retirement plans, bonuses and stock options. Bonus: salaries differ based on the size of the company (startup vs large corporation) and the type of company. Want to take your network career to the next level?🚀 DM and let me know how I can help you 🔥 #binaryavenue #networkengineer
