Part - I Project Scope


Objectives and Scope - I

• Project Name : Saudi Mobily WiMAX & LTE Project 5508500

• In order to meet the requirement of Mobily multiple networks deployment, Huawei presents multi-

mode BTS solution which is applicable for WiMAX/TDLTE multi-mode deployment and smooth

evolution from WiMAX to LTE

• Scope :

• 1)Huawei 265 WIMAX sites upgrade, and 150 new sites based on Huawei WIMAX coverage cities.

• 2) 99 new TDL and WIMAX co-sites will be built in the New cities.

• 3) 477 new TDL and WIMAX co-sites will be built in Easten, Madinah and Yanbo area.

• Huawei will introduce a new LTE network with two SAE geographically separated in location

within the same access network using single ran solution which will put up with the exceeding

data demands of end users.

Objectives and Scope - II

• Two new ASN-GW’s will be added to the existing network and will be installed in GOSI–Dammam and Silver-Khobar. Huawei is proposing two possible scenarios for the Target Network Topology. The distribution is done based on geographic location of cities keeping in mind the transmission delay consideration. Both scenarios are as following:

ScenarioScenarioScenarioScenario DescriptionDescriptionDescriptionDescription Advantage Risks Remarks

Scenario 1Install and then dismantle(Temp

frequency available)

This solutions is available . All the Installation and alignment can be done without MDT. It can be roll back

Small risk when MDT

Scenario 2Install and then dismantle(Temp

frequency unavailable)

This solutions is available when there is no Temp frequency. It can be roll back

Alignment time depending on the size of new antenna . Medium risk.

Scenario 3Direct swap then

install new link

This solution is available when there is no space available on the original infrastructure and no space to erect a new structure on the tower.

Link outage vary from case to case, depending on the size of the newly install antenna and path distance. And it can not be roll back. High risk.

Scenario 4 Re-rout

The outage downtime is short in solution. The link only stays down during the cutover. After re-routing, it can release some spaces on the congested infrastructure for future swap.

Need new licensed frequency and LOS risk .

Rollback PrinciplesWiMAX Rollback criteria:

•Base on number of sites unsuccessfull in SWAP cluster

WiMAX Rollback Actions:•Troubleshooting unsuccessfull sites during MDT•Request support to rollback to samsung.

MW Rollback criteria:• Base on number of sites unsuccessfull in SWAP cluster

MW Rollback Actions:

• Troubleshooting unsuccessfull sites during MDT• Request support from Trx team if required.

Proposed Solution6


Risks Analysis

• WiMAX Risks Involved:– On time support required to dismantle existing equipment and incase of rollback.

• MW Risks Involved:• 1. Some Fiber sites are not confirmed. This will affect the LOS &site survey. This still affect our implement

design.• 2. Swap risk:

– Customer request use the existing link’s frequency. It means we will face 2 scenarios: • Enough space to install. Can roll back but can not forecast how long the downtime it will be .• No space to install: first dismantle existing link, then install new link and alignment. This can not roll

back, high risk. And all the work on the tower need to be done in the day time.

• RNP Risks Involved:• In the swap period, everyday the network will have new provisional boundary with Samsung sites.

Because of this the HO KPI may be bad.But for that the wimax service is fixed wireless service so there is not some real heavy affection to the users.

• About the detail performance risk considering and solution preparation, Huawei need to first collect the Samsung current network information then do the analyse and report to Mobily.

Recommended Proposal:

1. Proposal One: – First Swap Wimax Sites– Then Swap MW transmission

2. Proposal Two: (Recommended)– Start Swap Wimax in Region A and SWAP MW in Region B simultaneously .

3. Proposal Three:– Precondition: Match RF cluster with MW link design

• 3.A: First Swap WiMAX according to RF clusters, Once all Wimax sites are Swapped in a particular MW link, then Swap MW for that Link.

• 3.B: Swap Both MW and WiMAX Simultaneously in same RF cluster. (Some sites might be require two or even more MDT’s depending on MW link design)

– BBU [Base Band Unit for WiMAX]

• Transmission Rack in Block-8 Should be utilized for installation unless

specified otherwise. [Block 8 is the right most 60 cm*60cm block when

entering the shelter ]

• 63A fuses should be used to connect DCDU with exist ing DC-

Distribution BOX [DCDB] installed usually on wall i n block 7 of the

shelter.

• If DCDB is full then the direct connection with rec tifier can be made but

power team approval is required from Mobily.

– DCDB uses round fuses while rectifier uses fuse with pins on top and

bottom.

OUTDOOR EQUIPMENT [Key points]

• Outdoor Equipments Include:

– RRU

– GPS Antenna

– Antenna RF

– Combiner

• GPS should be connected to BBU through antenna arre stor.

• Color Coding for feeder Antenna – Combiner , and CPR I for RRU – BBU is

extremely important to get rid of any cross connect ions.

• Swap Sites = RF Antenna azimuth for Existing [Samsu ng] Antennas should be

noted before installation of Huawei RF antennas.

• Three RRU power cables should be routed in one PVC pipe.

• Three RRU CPRI cables should be routed in one PVC p ipe.

• Its important to note RRU type Wimax/LTE , before i nstalling on pole/rack.

GPS Antenna Installation

• The location requirements for installing the GPS antenna are as follows:– Install the GPS antenna in open

air. The installation place should have no obstacles at the angle of 10° above the horizon.

– Keep the antenna away from high buildings and accessory construction on the roof.

– Install the GPS antenna on a platform as large as possible. The antenna must have an upright visual angle greater than 90°.

Note :In phase 1 we just leave this cable there because we don’t insert the LTE board yet.In phase 2 we can do the connection


1) Total RRU’s = 6 [3 for Wimax, 3 for LTE ]2) Total CPRI’s required = 9 [3 for Wimax , 6 for L TE ] which means each WiMAX RRU will use only 1 CPRI and each LTE RRU will us e 2 CPRI’s.3) For Project Phase 1 [Wimax 30MHZ]CPRI connection will be as follows:WiMAX RRU Sector 0 : no connection WiMAX RRU Sector 1 : no connectionWiMAX RRU Sector 2 : ConnectionLTE RRU Sector 0 : Connection [CPRI 0 only]LTE RRU Sector 1 : Connection [CPRI 0 only]LTE RRU Sector 2 : no Connection4) For Project Phase 2 [Wimax 10MHZ, LTE 20 MHZ]WiMAX RRU Sector 0 : ConnectionWiMAX RRU Sector 1 : ConnectionWiMAX RRU Sector 2 : ConnectionLTE RRU Sector 0 : ConnectionLTE RRU Sector 1 : ConnectionLTE RRU Sector 2 : Connection
