In addition to supporting GSM base station functions, HBTS also supports WiFi functions. Thus users can enjoy both GSM services and high-speed data services.
Intelligent frequency search and frequency point setting
ZXG10 S8001 automatically searches frequency points within the specified resource range and reports searched signal information to iBSC.
Carrier frequency point setting of the base station is determined by iBSC.
Since HBTS has small coverage range, it is both time consuming and arduous to plan frequency points by the traditional macro base station network planning and optimization method. Thus HBTS provides the intelligent frequency search and frequency point setting functions, providing convenience for users to the maximum extent.
Frequency deviation correction
ZXG10 S8001 can search for a nearby base station with the best signal quality, of which the FCCH is taken as reference. According to the reference, S8001 calculates the carrier frequency deviation between the current base station and the reference base station, and calculates the clock bias. Then, S8001 makes compensation to correct the frequency deviation.
PoE and local power supply, supports instant switching between PoE and local power supply
ZXG10 S8001 adopts DC -48 V for remote power supply, which is a safety power supply. The base station starts working once the network cable is connected. Installation is simple and convenient. IEEE802.3af PD controller is adopted, which can be connected with any hub satisfying IEEE802.3af PSE. The base station can be installed anywhere if the network cable is present. Considering that the old hub can not provide power supply, remote power supply equipments are added between hubs and base station.
The power supply mode is very flexible. Local power supply and remote power supply are combined and interfaces of the two modes are provided, satisfying requirements of various customers. It also supports automatic protection for over-voltage, under-voltage and over-current.
For PoE power supply, the maximum power consumption is 13 W. For local power supply, the power supply adapter is connected to 90 V AC ~ 260 V AC. The built-in battery in power supply adapter
Chapter 1 - Introduction
Confidential and Proprietary Information of ZTE CORPORATION 9
provides power supply for HBTS to work with full load up to 30 minutes in case of power failure.
All four frequency bands of GSM
HBTS supports the four frequency bands of GSM: 850 MHz/900 MHz/1800 MHz/1900 MHz. Priority is given to 900/1800 MHz.
Lightning Protection Level
The lightning protection level is C.
The external protection level (standard) is IP30.
Restart duration (due to power-off)
The duration of restart due to power-off is 60 s ~ 90 s.
BTS Synchronization Mode and Precision Requirement
HBTS supports both internal synchronization and external synchronization. The precision requirement is 0.1 PPM.
Maximum transmission power: 8PSK: 16 dBm; GMSK: 18 dBm
HBTS is used to solve indoor coverage problems for enterprise and home users, solving two kinds of problems:
1. Poor indoor coverage;
2. Network capacity is not enough (for enterprise and office applications) though indoor coverage is good.
Such purposes determine HBTS only covers shorter distance, for example, within 50 m. Thus the transmission power is restricted and is 16 dBm for 8PSK and 18 dBm for GSMK, satisfying the Pico-BTS transmission power requirement in GSM 05 05 of 3GPP specification. The maximum transmission power is according to the safe value approved by the industry for indoor solution.
Abis over IP
HBTS connects with iBSC through Abis interface and adopts IP bearer (Abis Over IP).
ZXG10 S8001 (V1.1) In-Door Pico Cell Base Transceiver Station User Manual
10 Confidential and Proprietary Information of ZTE CORPORATION
In downlink direction, HBTS receives the control signal sent by iBSC through network interface, and subsequently controls and manages HBTS radio channels. Meanwhile, HBTS sends the service data received from iBSC to radio terminal users.
In uplink direction, HBTS reports radio terminal user information to iBSC and sends radio terminal user data to iBSC after processing. In addition, HBTS also reports O&M information to network side through this interface, facilitating GSM O&M center for HBTS management and maintenance.
Radio Channel Management
In GSM system, radio channels are divided into two categories called logical channels and physical channels. ZXG10 S8001 performs mapping between logical channels and physical channels and controls and manages these channels.
Based on the channel configuration information sent by iBSC, ZXG10 S8001 performs the following functions for information transmitted on various channels:
Coding
Decoding
Digital modulating (GMSK or 8PSK)
Digital demodulating
Interleaving
De-interleaving
Encryption
Decryption
ZXG10 S8001 provides random access attempt test for radio terminal users and reports the information to iBSC to request assignment command, thus to complete a call.
ZXG10 S8001 performs uplink radio link measurement, sends the downlink radio link quality reported by radio terminal users to iBSC. It also performs preprocessing of received information.
ZXG10 S8001 reports the interference level and congestion on channels to iBSC. iBSC then judges and allocates channels, which improves the channel usage ratio.
ZXG10 S8001 sends the paging commands according to correct paging group requirements. These paging commands are sent from MSC and initiated by iBSC.

Um Interface and Radio Carrier Functions
ZXG10 S8001 modulates the GMSK/8PSK-modulated baseband signals on the carrier frequencies to be sent and transmits them into air after power amplification.
For Um interface, the site frequency error does not exceed ±0.1 PPM.
For GMSK modulation, Root Mean Square (RMS) of phase error does not exceed 5° and the peak value does not exceed 20°. For 8PSK modulation, RMS of EVM does not exceed 7% and the peak value does not exceed 22%.
ZXG10 S8001 demodulates the modulated carrier signal sent from radio terminal users and restores it to the baseband signal.
ZXG10 S8001 adjusts the transmission power according to measurement report and downlink power level reported by radio terminal users. This reduces the influence on radio channels of other users.
GSM/GPRS/EDGE/FR/EFR/HR/AMR Support
Considering working environment and performance/price ratio optimization, at most 7 TCH service channels are supported for GSM/GPRS and 2 ~ 4 PDTCH service timeslots are supported for EDGE.
In addition, it also supports Full Rate (FR), Enhanced Full Rate (EFR), Half Rate (HR), and Adaptive Multi Rate (AMR).

Ethernet Cable
The Ethernet cable is used to realize IP Abis and PoE. Connect the Ethernet cable with the network interface of S8001 directly.
Note:
If S8001 adopts PoE as the power supply mode, the HBTS gets power supply directly from the Ethernet cable.
Pay attention that the HBTS should be connected with a HUB that satisfies the IEEE802.3af PSE requirement. If the HUB is of old type and can not provide power supply, then a Remote Power Supply (RPS) should be added between the HUB and the HBTS.

Note: For the link parameter configuration of S8001, users could choose obtaining an IP address automatically or static link parameter configuration. While choosing to obtain an IP automatically, the local IP address, subnet mask and gateway of S8001 could be obtained automatically. The ALARM indicator and LINK indicator both flash at 5 Hz when fault appears. While choosing static link parameter configuration, the local IP address, subnet mask and gateway information need to be configured manually. The ALARM indicator flashes at 1 Hz when fault appears.
While choosing to obtain an IP address automatically, the fault may be caused by DHCP server error.
While choosing static link parameter configuration, the fault may be caused by LMT connection failure, flash writing failure, or timeout.
