Frequently Asked Questions
What topics do CafeTele telecom books cover?
CafeTele publishes 8 professional telecom engineering books covering 5G RAN optimization, O-RAN/Open RAN architecture, 5G NR physical layer, 4G & 5G RF planning, backhaul transport planning (IP/MPLS, microwave, fiber), 5G core network (SBA), AI/ML in telecom networks, and LTE to 5G migration (NSA/SA/EN-DC). All books are verified against official 3GPP and ITU-T specifications.
Are these books based on real 3GPP specifications?
Yes. Every CafeTele book is built entirely on official 3GPP specifications including TS 38.211, 38.213, 38.214, 38.215, 38.300, 38.321, 38.331, 28.552, 28.554, 23.501, 23.502, and 23.503. We use zero vendor-specific PM counter names — only standards-based terminology. This makes the books applicable regardless of whether you work with Ericsson, Nokia, Samsung, or Huawei equipment.
Can I preview the books before buying?
Yes, every book offers free preview chapters — typically the first 2–3 chapters — with no account required. You can read the table of contents, see the writing style, and evaluate the technical depth before purchasing.
Who are these books written for?
CafeTele books are written for telecom engineers, RF planners, optimization engineers, network architects, and technical managers working in 4G LTE and 5G NR networks. They are also valuable for students preparing for telecom interviews and professionals transitioning into 5G roles.
What payment methods are accepted?
We accept payments via Razorpay, supporting credit/debit cards, UPI, net banking (for India), and international cards. Prices are shown in both INR and USD. All purchases are one-time with lifetime access and free updates.
How is this different from vendor-specific documentation?
Unlike vendor documentation that uses proprietary parameter names and counter formats, CafeTele books are entirely vendor-neutral. We reference only 3GPP standard counter names (e.g., TS 28.552) and KPI definitions (TS 28.554). This means the knowledge transfers across Ericsson, Nokia, Samsung, and Huawei networks without relearning terminology.
