Elements of a Cellular System
- Mobile Stations (MS)
- Base Stations (BS)
- Mobile Switching Center (MSC)
- Public Switched Telephone Network (PSTN)
Understanding Hand-Over and Hand-Off
These are the necessary changes to keep communication channels uninterrupted when moving from one cell to another.

I. Introduction
Phase 1 of 5G is being standardized in 3GPP. 5G systems are expected to support various usage applications:
- Enhanced Mobile Broadband (eMBB)
- Massive Machine Type Communications (mMTC)
- Ultra Reliable Low Latency Communication (URLLC)
IMT-2020 (5G) is expected to provide the following key performance indicators (KPIs):
- > 10 Gbit/s peak data rate
- 100 Mbit/s user-experienced data rate
- 3x spectrum efficiency
- > 100 Mbps cell edge rates

Elements of Preparation for a Negotiation
- Reservation Point: The least favorable point at which a negotiator is willing to accept a deal. It’s essentially your “walk away” point.
- BATNA: Stands for Best Alternative To a Negotiated Agreement. It’s your best option if the current negotiation fails. A strong BATNA can increase your negotiating power.
- Target or Aspiration Points: These are the ideal outcomes or goals you hope to achieve in the negotiation. They represent what you’re aiming for instead of
